Step‑by‑Step Instructions for Butternut Squash Pasta Sauce
Step 1: Preheat Your Oven
Begin by preheating your oven to 450°F (232°C). This high temperature will help caramelize the veggies, adding depth to your Butternut Squash Pasta Sauce. While the oven heats, line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze.
Step 2: Prepare the Vegetables
Place the frozen diced butternut squash, fresh chopped tomatoes, and sliced yellow onion onto your prepared baking sheet. The squash will be the base of your creamy sauce, complemented beautifully by the sweetness of the tomatoes and onions. Ensure the veggies are spread out evenly for consistent roasting.
Step 3: Season and Drizzle
Drizzle 2 tablespoons of olive oil over the vegetables, then sprinkle with 1 teaspoon of salt, ¼ teaspoon of black pepper, and ½ teaspoon of dried thyme. These seasonings create a flavorful blanket for the veggies, enhancing the Butternut Squash Pasta Sauce's natural flavors. Toss everything gently to ensure even coverage.
Step 4: Roast the Vegetables
Slide the baking sheet into the preheated oven and bake for 20 minutes. You'll know they're ready when the squash is tender and slightly caramelized, while the tomatoes and onions are soft and aromatic. This roasting process transforms your ingredients, giving your sauce a wonderful depth.
Step 5: Cook the Pasta
While your veggies are roasting, bring a pot of salted water to a boil and cook 1 pound of pasta according to package instructions until al dente. Make sure to stir occasionally, ensuring even cooking. Reserve ⅓ cup of pasta water before draining to help adjust your sauce consistency later.
Step 6: Blend the Roasted Vegetables
Once the veggies are caramelized, carefully remove the baking sheet from the oven. Using a blender, combine the roasted vegetables with the reserved pasta water and blend until you achieve a smooth, creamy consistency. This blended mixture is your luscious Butternut Squash Pasta Sauce.
Step 7: Combine Sauce and Pasta
Pour the smooth sauce over your drained pasta in a large mixing bowl. Toss everything together gently to ensure the pasta is generously coated with the vibrant sauce. The heat from the pasta will help meld the flavors, creating a warm and inviting dish.
Step 8: Serve and Enjoy
Finally, serve your Butternut Squash Pasta Sauce immediately, topped with freshly grated parmesan cheese or a plant-based alternative for a delightful finishing touch. Embrace the comforting flavors in each bite and savor the satisfaction of homemade goodness!

Butternut Squash Pasta Sauce Recipe FAQs
What type of butternut squash should I use?
Absolutely! Using frozen diced butternut squash not only saves time but is also convenient. However, if you prefer a fresher option, choose a butternut squash that feels heavy for its size, with a firm, unblemished skin. Avoid any that have dark spots or soft patches, as these indicate overripeness.

Very! To freeze the sauce, pour it into a freezer-safe container, label it with the date, and it will keep well for up to 3 months. For best results, let the sauce cool completely before sealing. When you're ready to use it, thaw it in the refrigerator overnight or use the microwave for a quicker option.
What should I do if my sauce is too thick?
No worries! If your Butternut Squash Pasta Sauce turns out too thick, simply mix in some reserved pasta water—start with a tablespoon and add more as needed until you reach your desired consistency. This starchy water not only dilutes the sauce but also helps it cling to the pasta.
Is this sauce suitable for special dietary needs?
