No reviews

Sweet, caramelized butternut squash and crisp Brussels sprouts meet bright pesto and al dente pasta. This 2-step roasting and boiling method delivers peak autumn comfort.

  • Total Time: 35 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 12 ounces penne or rotini pasta
  • 1 small butternut squash, peeled and cubed (about 3 cups)
  • 1 pound Brussels sprouts, trimmed and halved
  • 3 tablespoons olive oil, divided
  • 1/2 cup basil or arugula pesto (store-bought or fresh)
  • 1/4 cup toasted pecans or walnuts, chopped
  • 1/4 cup grated Parmesan cheese (for topping)
  • Salt and freshly ground black pepper, to taste

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). On a large baking sheet, toss the cubed butternut squash and halved Brussels sprouts with 2 tablespoons of olive oil, salt, and pepper. Roast for 20-25 minutes, stirring halfway through, until the vegetables are tender and slightly caramelized.
  2. Step 2: While the vegetables are roasting, bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente. Reserve about 1/2 cup of the starchy pasta water, then drain the remaining water.
  3. Step 3: Return the drained pasta to the empty pot or a large mixing bowl. Immediately stir in the pesto and the remaining 1 tablespoon of olive oil, using a little of the reserved pasta water if needed to create a creamy coating.
  4. Step 4: Gently fold in the roasted squash and Brussels sprouts until evenly distributed. Toss in the toasted nuts and adjust seasoning with additional salt and pepper if necessary.
  5. Step 5: Serve the Autumn Harvest Pasta warm, garnished with a sprinkle of grated Parmesan cheese.

Notes

  • If you anticipate leftovers, store the toasted nuts and Parmesan separately, only adding them right before serving to keep their delightful crunch.
  • When reheating, gently warm the pasta in a skillet on the stovetop, adding a tablespoon of water or broth to restore the creamy consistency of the pesto sauce.
  • For a brighter flavor, serve the warm pasta with a generous sprinkle of fresh lemon zest or a squeeze of lemon juice just before eating.
  • Chef's secret: Do not crowd your roasting pan; use two baking sheets if necessary so the vegetables caramelize beautifully rather than steam, boosting their autumnal sweetness.
