  • Total Time: 40 minutes
  • Yield: 6 servings

Ingredients

Vegetables

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

Seasonings and Oils

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

Pasta

  • 1 lb pasta
  • 1/3 cup reserved pasta water from cooked pasta

Instructions

  1. Preheat Oven: Preheat your oven to 450°F and line a baking sheet with parchment paper to prepare for roasting the vegetables.
  2. Arrange Vegetables: Place the frozen diced butternut squash, chopped tomatoes, and sliced onion evenly on the prepared baking sheet.
  3. Season Vegetables: Drizzle the olive oil over the vegetables, then sprinkle with salt, black pepper, and dried thyme to evenly coat everything with seasoning.
  4. Mix Vegetables: Toss the vegetables gently on the baking sheet to make sure all pieces are well coated with the oil and spices.
  5. Roast Vegetables: Bake the vegetables in the preheated oven for 20 minutes until tender and slightly caramelized.
  6. Cook Pasta: While the vegetables roast, cook the pasta according to the package instructions until al dente.
  7. Reserve Pasta Water: Before draining the pasta, reserve 1/3 cup of the cooking water and place it into a blender.
  8. Blend Sauce: Immediately transfer the hot roasted vegetables to the blender with the reserved pasta water and blend until smooth to create a creamy sauce.
  9. Combine Pasta and Sauce: Pour the blended butternut squash sauce over the cooked pasta and toss well to coat the pasta evenly.
  10. Serve: Serve the pasta immediately, garnished with parmesan cheese or a plant-based alternative for added flavor.

Notes

  • Using frozen butternut squash saves peeling and chopping time while still delivering great flavor.
  • Reserve pasta water to help achieve a creamy sauce consistency without adding extra cream.
  • Feel free to add fresh herbs like basil or parsley for garnish.
  • If you prefer a smoother sauce, blend it longer or strain before tossing with pasta.
  • This sauce pairs well with short pasta shapes like penne or rigatoni, but any pasta works.
