Ingredients

Scale

Vegetables and Sauce

  • 16 oz bag of frozen diced butternut squash
  • 1.5 cups fresh chopped tomatoes
  • 1/2 yellow onion, sliced

Seasonings and Oil

  • 2 tbsp olive oil
  • 1 tsp salt
  • 1/4 tsp black pepper
  • 1/2 tsp dried thyme

Pasta

  • 1 lb pasta of choice
  • 1/3 cup reserved pasta water

Optional Garnish

  • Parmesan cheese or plant-based parmesan cheese

Instructions

  1. Preheat and Prepare Vegetables: Preheat your oven to 450°F (230°C). Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
  2. Arrange Vegetables: Place the frozen cubed butternut squash, fresh chopped tomatoes, and sliced yellow onion evenly on the prepared baking sheet.
  3. Season and Oil: Drizzle the olive oil over the vegetables, then sprinkle salt, black pepper, and dried thyme on top. Mix gently to coat the vegetables evenly with oil and seasonings.
  4. Roast Vegetables: Bake the seasoned vegetables in the preheated oven at 450°F for 20 minutes, or until the butternut squash is tender and starting to caramelize.
  5. Cook Pasta: While the vegetables are roasting, cook the pasta according to the package instructions until al dente. Just before draining, reserve 1/3 cup of the pasta cooking water and set it aside.
  6. Blend Sauce: Transfer the hot roasted vegetables to a blender. Add the reserved pasta water and blend until the mixture forms a smooth and creamy sauce.
  7. Toss Pasta with Sauce: Pour the blended butternut squash sauce over the cooked pasta. Toss well to coat all the noodles evenly with the sauce.
  8. Serve: Serve the pasta immediately, garnished with grated parmesan cheese or a plant-based alternative if desired, for an extra touch of flavor.

Notes

  • Using frozen diced butternut squash saves prep time but fresh can be used if preferred; adjust roasting time accordingly.
  • Reserve pasta water is crucial for thinning the sauce to your desired consistency and helps the sauce cling to the pasta.
  • Optional garnishes like fresh basil or red pepper flakes can enhance the flavor profile.
  • This sauce pairs well with any pasta shape, but short pasta like penne or rigatoni works especially well.
  • For a vegan version, omit the parmesan or use a plant-based cheese alternative.
