Preheat your oven to 450°F and line a baking sheet with parchment paper.
Spread the frozen diced butternut squash, chopped tomatoes, and sliced onion on the baking sheet.
Drizzle olive oil over the vegetables and sprinkle with salt, pepper, and dried thyme. Mix well to coat the vegetables evenly.
Bake in the preheated oven at 450°F for 20 minutes. (Cooking tip: Stir halfway through for even roasting.)
While the vegetables are baking, cook the pasta following the package instructions.
Before draining the cooked pasta, reserve 1/3 cup of the pasta water and set it aside.
Once the vegetables are done baking, transfer them to a blender along with the reserved pasta water. Blend until a smooth sauce forms.
Pour the butternut squash sauce over the cooked pasta and toss to coat the pasta evenly.
Serve the butternut squash pasta immediately, garnished with grated parmesan cheese or plant-based parmesan. (Tip: For a creamier sauce, add a splash of cream or milk when blending the vegetables.)
