Step‑by‑Step Instructions for butternut squash pasta sauce

Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (230°C). This high temperature is essential for roasting the butternut squash, tomatoes, and onion to perfection. While the oven heats, you can prepare the vegetables to ensure they roast evenly and develop a beautifully caramelized flavor.

Step 2: Prepare the Pasta Water
In a large pot, bring salted water to a boil for the penne pasta. The water should be bubbling vigorously before you add the pasta, which will cook according to package instructions. This step is crucial as it allows the pasta to achieve the right texture to pair with the creamy butternut squash pasta sauce later on.

Step 3: Mix the Vegetables
In a large bowl, combine diced butternut squash, plum tomatoes, and yellow onion. Drizzle with olive oil and sprinkle in salt, black pepper, fresh thyme, and red pepper flakes. Toss everything together until the vegetables are evenly coated. This mixture will roast beautifully, creating a rich and flavorful base for your sauce.

Step 4: Roast the Vegetables
Spread the seasoned vegetables in a single layer on a baking sheet. Roast in the preheated oven for 20-30 minutes, stirring halfway through. Keep an eye on them; you want the squash to be tender and slightly browned with a delicious caramelization. This step enhances the natural sweetness of the butternut squash pasta sauce.

Step 5: Cook the Pasta
While the vegetables roast, cook the penne pasta according to the package instructions until al dente. Remember to reserve ½ cup of the pasta cooking water before draining. This starchy water is a secret ingredient; it will help you achieve the desired creamy consistency in your sauce.

Step 6: Blend the Sauce
Once the vegetables are perfectly roasted, transfer them to a blender or food processor. Add the reserved pasta water to the roasted mix, then blend until smooth and creamy. If needed, you can adjust the consistency of your butternut squash pasta sauce by adding a little more pasta water until it reaches your preferred texture.

Step 7: Combine and Serve
Toss the creamy butternut squash pasta sauce with the cooked penne pasta in a large mixing bowl. Stir gently to coat all the pasta evenly with the sauce. To finish, serve with a drizzle of olive oil on top and a sprinkle of grated Parmesan cheese, if desired, for an extra burst of flavor.

Make Ahead Options

This creamy butternut squash pasta sauce is a fantastic meal prep option that saves you precious time on busy weeknights! You can roast the butternut squash, tomatoes, and onion up to 24 hours in advance. Simply cool the vegetables and store them in an airtight container in the refrigerator. When you’re ready to enjoy the sauce, blend the roasted veggies with reserved pasta water until smooth, and cook the pasta fresh to ensure it maintains its perfect texture. This way, you’ll have a delicious, nutritious butternut squash pasta sauce that’s just as flavorful as if made the same day, yet takes minimal effort to finish!
