How to Make Loaded Cauliflower Broccoli Casserole
Follow these simple steps to prepare this delicious dish:
Step 1: Prep the Veggies and Chicken
Preheat your oven to 375°F (190°C). Wash and cut the cauliflower and broccoli into bite-sized florets. Dice the chicken breast into small, roughly 1-inch cubes. Chop the onion and mince the garlic.
Step 2: Sauté the Aromatics
In a large skillet, melt the vegan butter over medium heat. Sauté the onions until softened, about 5 minutes. Add the garlic and cook for another minute until fragrant. Be careful not to burn the garlic.
Step 3: Cook the Chicken
Add the chicken cubes to the skillet and cook until browned and cooked through, about 7-10 minutes. Season with salt, pepper, paprika, garlic powder, and onion powder.
Step 4: Combine the Casserole Ingredients
In a large bowl, combine the cooked chicken, sautéed vegetables, cauliflower, broccoli, vegan cream of mushroom soup, and milk. Stir well to coat everything evenly. If using, stir in a small amount of agar-agar to help it set.
Step 5: Bake to Perfection
Pour the mixture into a greased 9×13 inch baking dish. Top with the vegan cheddar cheese and panko breadcrumbs. Bake for 30-35 minutes, or until golden brown and bubbly.
Step 6: Serve and Enjoy
Let the casserole cool slightly before serving. Serve warm, perhaps with a side of crusty bread for dipping into the creamy sauce.
This Loaded Cauliflower Broccoli Casserole is a triumph. It’s a culinary adventure that’s both easy and impressive. You’ll be the star of the next potluck. Trust me.
Perfecting the Cooking Process

First, roast the cauliflower and broccoli until tender-crisp. While those are roasting, prepare the cheese sauce. Combine the cooked vegetables with the sauce and bake until bubbly and golden brown. This ensures perfectly cooked vegetables and a creamy, delicious casserole.
Add Your Touch
Experiment with different cheeses for varied flavor profiles. Add sauteed mushrooms or onions for extra texture and depth. A sprinkle of fresh herbs like parsley or thyme adds a lovely aromatic finish to your Loaded Cauliflower Broccoli Casserole.
Storing & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until heated through. Avoid over-reheating, as this can dry out the casserole.
- Don’t overcook the vegetables; you want them tender-crisp, not mushy.
- Use good quality cheese for a richer, more flavorful cheese sauce.
- A little bit of nutmeg in the cheese sauce elevates the entire dish.

Ingredients You’ll Need
: A Gathering of the Culinary Clan
Before we embark on this culinary journey, let’s gather our ingredients. Think of it as assembling your superhero team, each player crucial to the final victory (a delicious casserole!).
For the Roasted Vegetables:
Large head of cauliflower, cut into florets
Large head of broccoli, cut into florets
2 tablespoons olive oil
1 teaspoon salt
1/2 teaspoon black pepper
For the Cheese Sauce:
1/4 cup butter
1/4 cup all-purpose flour
3 cups milk (or a plant-based milk alternative)
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon nutmeg (optional, but highly recommended)
2 cups shredded cheddar cheese (or a blend of your favorite cheeses)
1/2 cup shredded Gruyere cheese (optional, for extra richness)
Roasting the Vegetables
: Unleashing the Inner Fire
The secret to a truly spectacular Loaded Cauliflower Broccoli Casserole lies in the perfectly roasted vegetables. We’re not aiming for mushy florets here, folks; we want tender-crisp perfection. Preheat your oven to 400°F (200°C). Toss the cauliflower and broccoli florets with olive oil, salt, and pepper. Spread them out on a baking sheet in a single layer. Roast for about 20-25 minutes, or until tender-crisp and slightly browned. Keep an eye on them to prevent burning.
Crafting the Creamy Cheese Sauce
: A Symphony of Flavor
While your vegetables are roasting, let’s whip up a cheese sauce that would make even the most discerning cheese connoisseur swoon. Melt the butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to make a roux. Gradually whisk in the milk, ensuring there are no lumps. Bring the mixture to a simmer, stirring frequently, until it thickens slightly. Reduce the heat to low, stir in the salt, pepper, and nutmeg (if using). Remove from the heat and stir in the cheddar and Gruyere cheeses until melted and smooth. This is where your tastebuds will start doing a happy dance.
Assembling the Casserole
: The Grand Finale
Now for the exciting part! Preheat your oven to 375°F (190°C). In a large bowl, combine the roasted cauliflower and broccoli with the creamy cheese sauce.

FAQs
Can I make this Loaded Cauliflower Broccoli Casserole ahead of time?
Absolutely! This casserole actually tastes even better the next day. Prepare it completely, then cover it tightly and refrigerate it for up to two days.

You can even assemble it the night before, saving you precious time on the day you plan to serve it. Just pop it in the oven when you’re ready!
What can I substitute for the chicken broth?
Feeling adventurous? Experiment! Vegetable broth provides a similar savory base and works wonderfully. For a richer flavor, try beef broth. If you’re aiming for a lighter taste, chicken broth alternatives like mushroom broth or even a simple blend of water and bouillon cubes can work just as well. Remember to adjust seasonings to your preference after substituting the broth. The key is to find a broth that complements the other flavors in your Loaded Cauliflower Broccoli Casserole without overpowering them.
Is this Loaded Cauliflower Broccoli Casserole gluten-free?
Yes, this recipe is naturally gluten-free, assuming you use gluten-free breadcrumbs. Many commercially available breadcrumb brands offer gluten-free versions, and you can even make your own using gluten-free bread. Double-check your breadcrumbs’ ingredients to be absolutely certain. Making sure your breadcrumbs are gluten-free will keep this Loaded Cauliflower Broccoli Casserole completely safe for those with gluten sensitivities.
How can I make my Loaded Cauliflower Broccoli Casserole extra cheesy?
While this recipe is already bursting with cheesy goodness, there are ways to amplify that cheesy flavor! You could add a sprinkle of extra sharp cheddar or Parmesan cheese on top before baking. For a truly decadent experience, consider adding a layer of your favorite cheese sauce underneath the breadcrumb topping. A creamy cheese sauce adds another dimension to the casserole. Just remember that adding extra cheese will increase the overall calorie count, but hey, it’s worth it sometimes, right?
