How to Make Butternut Squash Pasta Sauce

Step 1: Preheat the Oven

Preheat your oven to 450°F (232°C) and line a baking sheet with parchment paper to prevent sticking.

Step 2: Prepare the Vegetables

Place frozen cubed butternut squash, chopped tomatoes, and sliced onion on the baking sheet.

Step 3: Season the Veggies

Drizzle olive oil over the vegetables. Season with salt, black pepper, and dried thyme.

Step 4: Mix Everything Together

Use your hands or a spatula to mix everything until all vegetables are evenly coated with oil and seasonings.

Step 5: Roast the Veggies

Bake at 450°F (232°C) for about 20 minutes or until tender and slightly caramelized.

Step 6: Cook the Pasta

While your veggies are roasting, cook your pasta according to package instructions until al dente.

Step 7: Reserve Pasta Water

Before draining the cooked pasta, reserve 1/3 cup of the starchy pasta water to help create a creamy sauce later.

Step 8: Blend the Roasted Vegetables

Once roasted, take the hot veggies out of the oven. Place them in a blender along with the reserved pasta water. Blend until you achieve a smooth sauce consistency.

Step 9: Combine Sauce and Pasta

Pour the creamy butternut squash sauce over your cooked pasta in a large mixing bowl. Toss gently to coat each piece of pasta evenly.

Step 10: Serve and Enjoy

Serve immediately with freshly grated parmesan cheese or plant-based parmesan for an extra burst of flavor!
