• Salt – Enhances flavor; adjust to taste and use kosher or sea salt.
• Black Pepper – Provides seasoning and a bit of heat; fresh cracked pepper is recommended for better flavor.

Step‑by‑Step Instructions for Butternut Squash Pasta Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (232°C) while you prepare your baking sheet. Line the baking sheet with parchment paper to prevent sticking and facilitate easy cleanup. This is the first step in creating your creamy butternut squash pasta sauce, so make sure your oven is hot and ready to roast those delicious vegetables.
Step 2: Prepare the Vegetables
Spread your frozen diced butternut squash, fresh chopped tomatoes, and sliced onion evenly on the prepared baking sheet. Ensure all the vegetables have some space between them to roast properly, allowing for even browning. This mix will create a flavorful base for your sauce, and the bright colors will make your kitchen feel warm and inviting.
Step 3: Season the Mixture
Drizzle a generous amount of olive oil over the vegetables, then sprinkle with salt, black pepper, and dried thyme. Use your hands or a spatula to toss everything well, ensuring all the vegetables are coated in oil and seasonings. This step infuses the butternut squash pasta sauce with rich flavor, setting you up for a truly delicious dish.
Step 4: Roast the Vegetables
Place the baking sheet in the oven and roast the vegetable mixture for about 20 minutes, or until they are tender and slightly browned. You'll know they're ready when the squash is easily pierced with a fork and has developed a lovely caramelization. Keep an eye on them, enjoying the tantalizing aroma filling your kitchen.
Step 5: Cook the Pasta
While the vegetables roast, bring a large pot of salted water to a boil. Add your favorite pasta and cook according to the package instructions until al dente. Before you drain the pasta, scoop out about ⅓ cup of the starchy cooking water into a small bowl to use later in your creamy butternut squash pasta sauce.
Step 6: Blend the Sauce
Once the vegetables are done roasting, transfer them to a blender along with the reserved pasta water. Blend until smooth and creamy. This step transforms your vegetables into a velvety sauce that will beautifully coat your pasta. Be cautious blending hot ingredients to avoid splattering, and enjoy watching the vibrant colors come together.
Step 7: Combine Pasta and Sauce
In a large mixing bowl, toss the cooked pasta with the creamy butternut squash sauce. Make sure each piece of pasta is thoroughly coated in the rich sauce. This step is crucial as it brings the two components together, creating a delightful harmony of flavors and textures ready to wow your family at the dinner table.
Step 8: Serve and Enjoy
Dish out the creamy butternut squash pasta sauce onto plates, serving it hot while it’s still comforting and delicious. If desired, top with cheese or a plant-based alternative for added flavor. This hearty meal captures the essence of fall and is perfect for those cozy dinner moments shared with loved ones.

Butternut Squash Pasta Sauce Recipe FAQs
How do I choose the best butternut squash?
Absolutely! Look for butternut squash that feels heavy for its size, indicating it’s ripe and full of moisture. The skin should be a vibrant beige with a few dark spots, as these signify that it has developed flavor. Avoid squash with too many blemishes or soft spots.
How long can I store the butternut squash pasta sauce in the fridge?
You can keep your creamy butternut squash pasta sauce in an airtight container in the refrigerator for up to 7 days. This is perfect for meal prep; just make sure to let it cool down to room temperature before sealing it for storage!
Can I freeze butternut squash pasta sauce?
Absolutely! To freeze, transfer your cooled pasta sauce into a freezer-safe container or resealable bag. Make sure to label it with the date, and it can stay fresh for up to 3 months. For best results, defrost it in the fridge overnight before reheating.
What should I do if my sauce is too thick?
If you find your butternut squash pasta sauce is too thick, don’t worry! Simply stir in some reserved pasta cooking water, a little at a time, while mixing on low heat. You can also add vegetable broth or a splash of plant-based milk to achieve your desired consistency.
Is this recipe suitable for those with nut allergies?
Very! This creamy vegan butternut squash pasta sauce is nut-free, making it a safe choice for those with nut allergies. However, always double-check your other ingredients—like any add-ons you plan to use—just to be sure they meet your dietary needs.
Can I use fresh butternut squash instead of frozen?
Definitely! If you prefer fresh, peel, seed, and cube approximately 2 cups of butternut squash. Roast it alongside the other vegetables, but keep an eye on the cooking time, as fresh squash may take a bit longer to become tender, around 25–30 minutes.
