Get ready to transport your taste buds straight to the bayou and back, all within 20 minutes, because life is too short for boring fish and long prep times.

  • This recipe delivers an incredible flavor contrast, pairing the smoky heat of a robust Cajun spice rub with a vibrant, cooling lime and avocado dressing.
  • Achieve flaky perfection every time; baking salmon ensures minimal effort and easy cleanup, making this dish ideal for chaotic weeknight dinners.
  • The striking visual appeal features rich orange-red fish against the bright green sauce, guaranteed to impress guests, or just your hungry self.
  • Incredibly versatile, this spicy baked fish pairs beautifully with simple rice, roasted root vegetables, or even a fresh summer salad for a complete meal.

The Tale of the Two Sauces: Why This Flavor Combination Works

I must confess, my relationship with weeknight cooking used to be purely transactional: minimal effort, maximum edible result. This recipe, however, taught me that culinary excellence does not require a full eight-hour workday in the kitchen. I first concocted this Cajun-inspired dish during a particularly aggressive heatwave when the thought of stirring anything for more than five minutes felt like a personal insult.

The inspiration came from a moment of pure spice craving colliding violently with a deeply overripe avocado. Most people think of creamy sauces as heavy, but here, the avocado and lime transform into a light, almost ethereal dressing. It’s the perfect foil for the intense, earthy kick of the spice-rubbed salmon. Without the cooling agent, that Cajun crust might send your palate running for the hills, but the bright, tangy sauce is the perfect peacekeeper.

Think of it as a culinary negotiation: the salmon brings the heat, the sauce brings the chill, and your mouth enjoys the benefits of their beautiful, delicious compromise. It’s the kind of dish you make when you want to feel like a five-star chef but only have the time and energy of a sleepy raccoon.

Why Salmon is the Ultimate Weeknight Hero

Salmon truly deserves a medal for its services to quick dinners. It cooks fast, it takes seasoning like a champ, and it manages to feel fancy even when paired with nothing but a fork. When preparing the salmon fillets, always pat them completely dry before applying the Cajun rub. Dry surfaces ensure that the spices create a beautifully crisp, dark crust instead of steaming off, which results in lackluster flavor. Baking it at a high temperature, typically 400°F (200°C), guarantees a moist interior and a speed-run dinner, usually done in about 12 to 15 minutes, depending on the thickness.

Mastering the Cajun Spice Blend for Maximum Flavor

The Cajun rub is the backbone of this dish. Forget those bland spice shakers lurking in the back of your cupboard; we need flavor that speaks with an unmistakable, resonant accent. This homemade blend relies on depth from paprika and chili powder, earthiness from oregano and thyme, and a glorious wallop of heat from cayenne pepper. Remember, you control the volume on the spice rack. If you prefer a gentle hum to a full-blown siren, simply dial back the cayenne.

When you apply the spice blend, don’t be shy. Massaging the rub directly onto the fish is crucial; the oils on the salmon will help the spices adhere and bloom during baking. The magic really happens when the oils in the fish melt, fusing with the dry spices to create that irresistible, blackened crust we all crave. This intense flavoring on the fish is precisely what requires the beautiful cool contrast provided by the Creamy Avocado Lime Sauce.

Balancing Heat and Smoke: Tips for Customizing the Spice

To achieve a deeper, smokier flavor without adding actual smoke, utilize smoked paprika rather than the regular sweet variety. This substitution adds instant complexity. If you are serving this dish to children or those sensitive to heat, substitute half of the cayenne pepper with extra onion powder or garlic powder. These additions maintain the savory foundation without overwhelming the palate with heat. Always prepare a double batch of the rub and store it in an airtight container for future weeknight dinner emergencies—it works wonders on turkey cutlets and chicken breasts too.

The Secret Weapon: Creamy Avocado Lime Sauce

The avocado lime dressing is the reason theBaked Cajun Salmon | Creamy Avocado Lime Saucebecame a weeknight staple. It is bright, zesty, ridiculously easy to make, and provides an addictive, creamy texture without any dairy whatsoever. The sauce is truly the culinary equivalent of hitting the “reset” button after a bite of fiery, spiced fish.

To make this vibrant green elixir, you need a high-powered blender or food processor. The key is using ripe, almost yielding avocados; they provide the necessary fat and structure. We boost the flavor with fresh cilantro—which adds herbaceous brightness—a sharp punch of lime juice, and just a splash of water or broth to ensure it drizzles beautifully rather than sitting in a thick, unmoving blob. If your sauce is too thick, resist the urge to add cream; instead, add broth, a tablespoon at a time, until the consistency mimics a pourable vinaigrette.

This sauce is so good, you will want to put it on everything. It transforms simple grilled vegetables, makes an exceptional dip for tortilla chips, and can even be used as a luscious spread on sandwiches.

Achieving Peak Creaminess Without Dairy

The secret to non-dairy creaminess lies in the healthy fats provided by the avocado itself. For a super smooth texture, always make sure the blender runs long enough to completely emulsify the ingredients. If you find your avocado sauce separating after refrigeration, don’t worry—this is normal. Simply whisk it vigorously or give it a quick pulse in the blender just before serving to restore that velvety smooth texture. The lime juice acts as a natural stabilizer, preventing the avocado from browning too quickly, meaning you can often make the sauce a few hours ahead of time.

Perfect Pairings for Your Cajun Salmon

Since the salmon already delivers substantial flavor and richness, pairing it with simpler, lighter side dishes works best. I often serve this spicy baked fish over fluffy jasmine rice that soaks up any extra sauce. Roasted sweet potatoes or simple steamed green beans tossed with olive oil and salt are also excellent choices. For a fresher take, serve theBaked Cajun Salmon | Creamy Avocado Lime Sauceatop a bed of mixed greens with corn and black beans for a vibrant, satisfying salad.

Ingredients for Baked Cajun Salmon | Creamy Avocado Lime Sauce

Here’s what you’ll need to make this delicious dish:

  • Salmon FilletsLook for four equally sized, skin-on or skin-off portions, ensuring they are about 6 ounces each for even cooking.
  • Olive OilThis acts as a binder for the rub and prevents the fish from sticking to the baking sheet.
  • Cajun Spice MixA robust blend including smoked paprika, cayenne, garlic powder, onion powder, dried oregano, and thyme to deliver intense flavor.
  • AvocadosSelect two ripe Hass avocados; they should yield slightly to gentle pressure for optimal creaminess.
  • Fresh Lime JuiceCrucial for balancing the fat in the avocado and providing a necessary acidic kick to cut through the heat of the salmon.
  • CilantroA large handful of fresh cilantro leaves adds brightness and an essential herbaceous note to the dressing.
  • Garlic CloveOne small clove provides savory depth to the sauce without overwhelming the lime and avocado flavors.
  • Water or Vegetable BrothUsed only to thin the sauce to a perfect drizzly consistency.
  • Salt and PepperEssential seasonings for both the fish and the sauce, always use coarse sea salt or Kosher salt.

The full ingredients list, including measurements, is provided in the recipe card directly below.

How to Make Baked Cajun Salmon | Creamy Avocado Lime Sauce

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat and Prep the Salmon

Preheat your oven to 400°F (200°C). Line a sturdy baking sheet with parchment paper for easy cleanup. Pat the salmon fillets completely dry using paper towels. Drying the surface is critical for achieving a crisp crust. Lightly brush the fillets with olive oil on all sides.

Step 2: Apply the Cajun Rub

In a small bowl, combine all the dry Cajun spice ingredients, ensuring the mixture is homogeneous. Generously coat all sides of the salmon fillets with the spice blend, pressing the spices into the flesh firmly. Place the seasoned fish onto the prepared baking sheet, leaving space between the pieces.

Step 3: Bake the Salmon to Perfection

Bake the salmon for 12 to 15 minutes. The precise cooking time depends on the thickness of your fillets and your desired doneness. The fish is ready when it flakes easily with a fork and the internal temperature reaches 145°F (63°C). Do not overbake, or the fish will dry out.

Step 4: Prepare the Creamy Avocado Lime Sauce

While the fish bakes, combine the ripe avocado, fresh lime juice, cilantro, garlic clove, and a pinch of salt in a blender or food processor. Blend until completely smooth. If the sauce is too thick, add water or vegetable broth, one tablespoon at a time, until it reaches a thick, pourable consistency.

Step 5: Rest and Serve

Once the salmon finishes baking, remove it from the oven and allow it to rest for about three minutes; this locks in the juices. Transfer the hotBaked Cajun Salmon | Creamy Avocado Lime Sauceto individual plates. Generously spoon or drizzle the vibrant green sauce over the top of the fiery fish. Transfer to plates and drizzle with sauce for the perfect finishing touch.

Frequently Asked Questions About Baked Cajun Salmon

You can definitely prepare the Creamy Avocado Lime Sauce up to four hours in advance. Store it in an airtight container in the refrigerator, pressing plastic wrap directly onto the surface of the sauce to minimize air exposure. The acidity of the lime juice helps prevent browning.

If you need to avoid all heat, replace the Cajun seasoning with a smoky, savory blend like Creole seasoning that omits the cayenne, or use a simple mix of smoked paprika, dried thyme, brown sugar, and onion powder for depth without the burn.

Absolutely! The Cajun rub and creamy sauce work beautifully with other sturdy white fish fillets, such as halibut or cod. Adjust the baking time accordingly, as thicker cuts of fish may require a few extra minutes in the oven to cook thoroughly.

Store leftover salmon separately from the sauce. Keep the cooked salmon in an airtight container for up to three days. Store the sauce in a sealed container in the refrigerator for up to 48 hours. Reheat the salmon gently in a low oven or air fryer to maintain moisture.

We are about to swap out that kitchen dread for a culinary triumph that feels utterly decadent yet takes minimal effort. I’m talking about a dish so vibrant and perfectly balanced it should frankly come with a warning label: potential obsession ahead.

For years, I believed quick meals had to be bland. Then I discovered the power of contrasting textures and temperatures.

Get ready to master the ultimate duality: intensely seasoned, high-heatBaked Cajun Salmon | Creamy Avocado Lime Sauce.

The beauty of this recipe lies in its simplicity. We rely on the oven to handle the heavy lifting for the salmon, resulting in a tender, moist fillet every time, while the vibrant, zesty sauce comes together in the time it takes the oven to preheat. Forget complicated cooking techniques; we focus purely on maximizing flavor impact with minimal fuss.

The Essential Ingredients for Maximum Impact

You might already have most of these ingredients hiding in your pantry. We are using standard kitchen staples, spiced up with a fantastic homemade (or good quality store-bought) Cajun blend. Remember, quality salmon makes all the difference here, so choose thick, well-marbled fillets if possible.

For the Baked Cajun Salmon

  • 4 (6-ounce) salmon fillets, skin on or off
  • 1 tablespoon olive oil
  • 2 teaspoons smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • ½ teaspoon cayenne pepper (adjust for heat preference)
  • ½ teaspoon dried thyme
  • Salt and freshly ground black pepper to taste

For the Creamy Avocado Lime Sauce

  • 2 ripe avocados, peeled and pitted
  • ½ cup plain Greek yogurt (full fat recommended for texture)
  • Juice of 2 large limes (about ¼ cup)
  • ¼ cup fresh cilantro, packed
  • 1 small clove garlic
  • 2 tablespoons water (or chicken broth, to adjust thickness)
  • Pinch of salt

The Method: From Prep to Plate

The secret to dinner efficiency is starting the oven immediately. Preheat your oven to a fiery 400°F (200°C). This allows the salmon to cook quickly, retaining moisture and yielding that fantastic flaky texture we all crave.

Seasoning the Fillets

First, combine all your Cajun spices—paprika, garlic powder, onion powder, oregano, cayenne, and thyme—in a small bowl. Pat your salmon fillets dry; this is critical for achieving a beautiful crust and helping the seasoning adhere properly. Brush the fillets lightly with olive oil, then generously coat them with the spice mixture, gently pressing the spices into the fish flesh. Place the seasoned salmon on a baking sheet lined with parchment paper.

Crafting the Creamy Avocado Lime Sauce

While the oven is heating, prepare the luscious sauce. This zesty avocado dressing balances the spicy salmon perfectly. In a food processor or high-powered blender, combine the avocado, Greek yogurt, lime juice, cilantro, garlic, and salt. Pulse until the mixture is smooth and creamy. If you prefer a thinner consistency, add water or broth one tablespoon at a time until you reach your desired texture. Taste and adjust the lime or salt as needed—sometimes, a little extra zing is exactly what you need!

Baking and Final Presentation

Bake the salmon for 12 to 15 minutes, depending on the thickness of the fillets. The internal temperature should reach 145°F (63°C), and the fish should flake easily with a fork. Once cooked, let the salmon rest for a minute or two before serving. Serve the hot, intensely flavorfulBaked Cajun Salmonimmediately, generously drizzled with or alongside a cool dollop of the Creamy Avocado Lime Sauce. This contrasting temperature and flavor profile is truly sensational.

Perfecting the Cooking Process

Achieve culinary efficiency by preparing the creamy avocado lime sauce first, storing it covered in the refrigerator while the oven preheats. Next, season the salmon aggressively before immediately placing it in the hot oven. This sequencing ensures the fish is served piping hot, ready to be paired with the refreshing, chilled sauce.

Add Your Touch

Feel free to experiment with this recipe! Swap out the salmon for cod or chicken breast, adjusting the cooking time accordingly. For a smoky flavor depth, consider adding a dash of liquid smoke to the Cajun spice blend. Alternatively, fold in a tablespoon of finely diced red onion into the sauce for a delightful textural bite.

Storing & Reheating

Store leftover salmon and the creamy avocado lime sauce separately in airtight containers for up to three days. Reheat the salmon gently in a toaster oven or air fryer to maintain crispiness. Avoid microwaving the sauce, as heating avocado can alter its beautiful color and texture.

My grandmother once tried this recipe, claiming she “didn’t like spicy food,” only to ask for seconds and then thirds. She even tried dipping her morning toast in the leftover avocado sauce—that’s when I knew I had a winner.

Chef’s Expert Tips for Flawless Results

  • Don’t skip patting the salmon dry; moisture prevents the Cajun spices from forming a beautiful, flavorful crust during the high-heat baking process.

  • Use high-quality Greek yogurt in the sauce, as it provides the necessary tang and richness, ensuring the dressing stays thick without needing excess stabilizers.

  • Check the salmon for doneness by inserting a fork into the thickest part; it should easily separate into large, moist flakes when fully cooked.

Choosing the Perfect Sides

While the salmon and sauce combo is certainly the star of the show, a truly balanced meal needs supporting actors. Pairing spicy, rich flavors requires something refreshing and slightly acidic or starchy to complete the palate experience. We recommend sticking to light, vibrant sides that complement the lime and cilantro notes in the sauce.

Fantastic Pairings for Spicy Salmon

A simple yet elegant choice is Lemon Herb Rice Pilaf. The citrus helps cut through the richness of the fish. If you prefer a lighter carb alternative, try a Quinoa Salad tossed with cucumber, bell peppers, and a simple vinaigrette. For a vibrant green vegetable, look no further than perfectly roasted asparagus or green beans dusted lightly with salt and pepper.

Alternatively, if you are hosting a gathering, consider serving this over crunchy, thinly sliced cabbage slaw dressed lightly with apple cider vinegar. The added crunch and tanginess provide a satisfying contrast to the soft salmon and creamy sauce, making every bite dynamic and interesting.

The Science Behind the Flavor Contrast

Why exactly does the pairing of fiery Cajun seasoning and cool avocado work so miraculously well? It’s simple flavor science, really. Capsaicin, the chemical compound responsible for the heat in chili peppers, dissolves poorly in water but readily in fat. The healthy fats present in the salmon and, more significantly, the dense, rich avocado sauce, effectively neutralize the heat while allowing the depth of the Cajun spice profile to shine through.

This means you get all the complex, savory, and aromatic notes of the spices—the oregano, garlic, thyme, and paprika—without the lingering, overwhelming burn. This is a dish designed for maximum sensory enjoyment, offering comfort through its texture and excitement through its bold flavor.

Don’t be afraid to make this a staple in your meal rotation. It’s ideal for impressive weekend entertaining and easy enough for a Tuesday evening. The quick prep and baking time mean you spend less time hovering over the stove and more time basking in the glow of a job well done. Mastering theBaked Cajun Salmon | Creamy Avocado Lime Sauceis truly a badge of honor in the modern kitchen.

Frequently Asked Questions About Baking Salmon

How do I ensure my salmon doesn’t dry out?

Avoid Overcooking

The single biggest mistake is overcooking. Use a meat thermometer to pull the fish out precisely when it reaches 145°F. Since the salmon continues to cook slightly after removal (carryover cooking), aim for the lower end of the time range if you prefer medium-rare.

Can I grill the salmon instead of baking it?

Grilling Instructions

Absolutely! Coat the salmon as directed, then grill over medium-high heat, skin side down, for about 5 to 7 minutes until the skin is crispy. Flip and cook for another 2 to 4 minutes until done. Grilling adds an extra layer of smoky char that complements the Cajun seasoning beautifully.

Can the Creamy Avocado Lime Sauce be made ahead of time?

Prep Timing for Avocado Sauce

Yes, but with caveats. Because avocados tend to oxidize quickly, the sauce is best made within 2 hours of serving. The high amount of lime juice helps preserve the green color, but you should always store it tightly covered in the refrigerator to minimize air exposure.

The Weeknight Warrior: Conquering Bland Dinners with Flavor

We’ve all been there: staring into the fridge, desperately searching for dinner inspiration that doesn’t involve yet another boring sheet pan chicken. You deserve excitement! You need a dish that punches you playfully in the mouth with spice, then immediately offers a cooling, velvety hug. That’s exactly why you need this recipe forBaked Cajun Salmon | Creamy Avocado Lime Saucein your life.

This isn’t just fish; it’s a culinary vacation. Imagine tender, flaky salmon coated in a robust, smoky spice blend, baked until absolute perfection. Then, picture a vibrant green sauce—smooth, tangy, and rich—drizzled liberally over the top. It’s the perfect marriage of fire and ice, demanding attention at the dinner table but ready in under 30 minutes. Forget the takeout menus; we are crafting magic tonight.

The Secret to the Perfect Cajun Spice Rub

If you’re buying pre-made Cajun seasoning, stop right now. We are building flavor from the ground up, and trust me, it’s worth the extra sixty seconds. A great Cajun rub isn’t just about heat; it’s about depth. We use paprika for smokiness and color, onion and garlic powder for aromatic foundation, dried thyme for herbaceous notes, and of course, cayenne pepper for that essential kick. Mix it all up, and don’t be shy about coating your salmon fillets completely. Think of it as giving your fish a vibrant, spicy blanket before its tanning session in the oven. Generously rubbing the spices ensures every bite bursts with authentic Louisiana flavor.

Crafting the Creamy Avocado Lime Sauce

The salmon brings the heat, so the sauce must bring the chill. This creamy avocado lime sauce is the superhero sidekick of this dish. It’s unbelievably simple but delivers monumental flavor. We combine ripe Hass avocados (the creamier the better), fresh lime juice for necessary acid, a splash of water or broth to achieve that beautiful drizzle consistency, and a hint of fresh cilantro. The goal is a velvety smooth texture that perfectly complements the spicy, flaky salmon. Use a blender or food processor to whip it until it resembles a smooth, emerald green dream. Taste it! Does it need more lime? Be bold. The acidity is crucial for cutting through the richness of the fish and the avocado.

Ingredients for the Ultimate Flavor Combination

Gathering your ingredients is the first step toward flavor domination. Quality salmon is key here, so look for thick, pink fillets. The thickness helps keep the interior juicy while the exterior crisps up nicely under the Cajun spice.

Ingredients List: Cajun Salmon

  • Four 6-ounce salmon fillets (skin on or off, your preference)
  • 1 tablespoon smoked paprika
  • 1 tablespoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1/2 teaspoon cayenne pepper (adjust to desired heat)
  • 1 teaspoon sea salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon olive oil

Ingredients List: Creamy Avocado Lime Sauce

  • 1 large, ripe avocado
  • Juice of 2 large limes (about 1/4 cup)
  • 1/4 cup fresh cilantro leaves
  • 2 tablespoons water or vegetable broth
  • 1/2 teaspoon sea salt

Step-by-Step Instructions for Baked Cajun Salmon

Preparation and Baking

  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup—because nobody wants to scrub pans after eating this masterpiece.
  2. In a small bowl, mix all the Cajun spice ingredients (paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and pepper).
  3. Pat the salmon fillets dry. This is important for achieving a crispier spice crust. Brush each fillet lightly with olive oil, then generously coat all sides with the Cajun seasoning mix, pressing it gently onto the fish.
  4. Place the seasoned salmon fillets onto the prepared baking sheet.
  5. Bake for 12 to 15 minutes, depending on the thickness of the fish, until the salmon is opaque, flakes easily with a fork, and reaches an internal temperature of 145°F (63°C).

Making the Creamy Avocado Lime Sauce

  1. While the salmon is baking, prepare the sauce. Combine the avocado, lime juice, cilantro, salt, and water/broth in a high-speed blender or food processor.
  2. Blend until the sauce is completely smooth and creamy. If the sauce is too thick, add water or broth one tablespoon at a time until you reach a pourable, drizzle-friendly consistency.
  3. Taste and adjust seasoning. You might need a pinch more salt or a squeeze of lime to brighten the flavor.

Serving Suggestions: Pairing for Perfection

Once the salmon emerges from the oven, flaky and fragrant, you are ready to serve. Drizzle that gorgeous creamy avocado lime sauce over the top immediately. What do you serve alongside such a flavor explosion? Keep it simple yet complimentary. A simple coconut rice provides a great, slightly sweet counterpoint to the spice, or maybe roasted sweet potatoes for an earthy balance. A simple side salad dressed with a light vinaigrette also works wonders, ensuring the focus remains squarely on the star of the plate: your perfectly spiced fish.

Conclusion for Baked Cajun Salmon | Creamy Avocado Lime Sauce

This recipe proves that weeknight meals should never be boring or complicated. We successfully transformed simple salmon fillets into a vibrant, flavor-packed experience using a homemade Cajun spice blend that brings serious heat and aromatic depth. The true genius of this dish, however, lies in the accompanying creamy avocado lime sauce. This velvety, tangy, and cool counterpoint perfectly cuts through the salmon’s richness and the spice’s warmth. Whether you are aiming to impress guests or just treating yourself after a long day, this balanced, easy-to-make Baked Cajun Salmon | Creamy Avocado Lime Sauce guarantees a meal that tastes like you spent hours in the kitchen, when in reality, you conquered dinner in minutes.

FAQs

How long can I store the leftover Baked Cajun Salmon | Creamy Avocado Lime Sauce?

You can safely store leftover baked Cajun salmon in an airtight container in the refrigerator for up to three days. It reheats best gently in the oven or air fryer to maintain its flaky texture and prevent drying out. Regarding the creamy avocado lime sauce, because it contains fresh avocado, it tastes best consumed immediately. If you must store it, cover it tightly with plastic wrap pressed directly onto the surface of the sauce to minimize air exposure. This technique helps reduce browning, allowing you to use the sauce the following day, though the color might slightly degrade.

Can I use a different fish instead of salmon for this Cajun recipe?

Absolutely! While salmon’s rich fat content holds up wonderfully to the robust Cajun spices, you can certainly substitute it. Flaky white fish like cod, halibut, or even firm options like mahi-mahi work beautifully with this spice blend. If using a thinner fillet, reduce the baking time to approximately 8 to 10 minutes to prevent overcooking. Regardless of the fish you choose, remember that the cooling element provided by the creamy avocado lime sauce is essential for balancing the heat from the seasoning.

What is the best way to prevent the avocado sauce from turning brown?

Avocado naturally oxidizes quickly, leading to an unappetizing brown color. The high amount of fresh lime juice in this creamy avocado lime sauce acts as the primary defense against oxidation. To maximize green color retention, blend the sauce right before serving and store any leftovers immediately. When storing, pour the sauce into a small container and press a layer of plastic wrap directly onto the surface, sealing out air completely. Stored this way, the sauce retains its vibrant green color for up to 24 hours.

Is it possible to prepare the spice rub for the Cajun salmon ahead of time?

Preparing the Cajun spice rub ahead of time is a fantastic time-saving strategy for busy weeknights. Simply mix all the dried spices together and store them in a small, sealed jar away from heat and moisture. This homemade blend remains potent for several months. When ready to cook, all you need to do is pat down your salmon fillets, coat them generously with the pre-mixed rub, and pop them into the oven. This speeds up dinner prep significantly while ensuring maximum flavor infusion in your baked Cajun salmon.
