Butternut Squash Pasta Sauce Ingredients
For the Sauce
• Frozen Diced Butternut Squash – The main base for the creamy sauce; using fresh butternut squash is also an option for a more intense flavor.
• Fresh Chopped Tomatoes – Adds a burst of acidity and freshness; if you’re in a pinch, canned tomatoes can be a suitable substitute but may alter the taste.
• Yellow Onion – Provides depth and sweetness to the sauce; shallots can be used for a milder flavor if preferred.
• Olive Oil – Essential for roasting the vegetables and adding richness; feel free to swap with avocado oil for a variation.
• Salt – A crucial ingredient for enhancing the sauce’s flavor—always adjust to your taste!
• Black Pepper – Adds a hint of spice; omit if you’re looking for a milder dish.
• Dried Thyme – Infuses the sauce with a wonderful herbal aroma; fresh thyme can elevate the flavor if you increase the quantity slightly.
For Cooking
• Pasta – Choose your favorite type, whether it’s traditional or gluten-free, to pair with the sauce.
• Reserved Pasta Water – This is key for achieving the right sauce consistency; don’t skip this step as it binds the sauce beautifully to the pasta.—can be substituted with vegetable broth if needed.
Step‑by‑Step Instructions for Creamy Vegan Butternut Squash Pasta Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (232°C). While the oven warms, line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze. This high temperature will beautifully caramelize your vegetables, enhancing their natural sweetness in the butternut squash pasta sauce.
Step 2: Prepare the Vegetables
Spread the frozen diced butternut squash, fresh chopped tomatoes, and yellow onion evenly on the prepared baking sheet. This arrangement allows the ingredients to roast uniformly. Make sure everything has enough space; you want them to roast rather than steam, achieving the vibrant flavors needed for your creamy sauce.
Step 3: Season and Toss
Drizzle the vegetables with olive oil, then sprinkle with salt, black pepper, and dried thyme. Using your hands or a spatula, toss everything gently to ensure an even coating of olive oil and seasonings. This step is essential for developing that rich, savory flavor that defines your butternut squash pasta sauce.
Step 4: Roast the Vegetables
Place the baking sheet in the preheated oven and roast for about 20 minutes. You’ll know they’re ready when the squash is tender and the edges of the tomatoes and onions turn a lovely golden color. This roasting process enhances their natural sweetness, setting the foundation for a delightful creamy sauce.
Step 5: Cook the Pasta
While the vegetables are roasting, bring a pot of salted water to a boil and cook your pasta according to the package instructions. Before draining, reserve about 1/3 cup of the pasta water to help adjust the sauce’s consistency later. Set aside the reserved water, then drain the pasta, returning it to the pot.
Step 6: Blend for Creaminess
After removing the roasted vegetables from the oven, let them cool slightly. Then, transfer them to a blender or food processor. Add the reserved pasta water to the blender and blend until smooth and creamy, creating the perfect consistency for the butternut squash pasta sauce.
Step 7: Combine and Serve
Pour the creamy sauce back into the pot with the drained pasta, tossing gently to combine the two evenly. Allow the heat to warm everything together for a minute or two. The butternut squash pasta sauce should cling beautifully to the pasta—serve immediately for a cozy meal, topped with your choice of grated parmesan or vegan cheese.

Storage Tips for Butternut Squash Pasta Sauce
Fridge: Store leftover butternut squash pasta sauce in an airtight container for up to 7 days. This keeps your sauce flavorful and fresh, ready for quick meals.
Freezer: For longer storage, freeze the sauce in individual portions for up to 3 months. Use freezer-safe containers or bags, removing as much air as possible to prevent freezer burn.
Reheating: To reheat, thaw the frozen sauce overnight in the fridge and warm gently on the stove, adding a splash of water or vegetable broth to achieve the desired consistency.
Container Guidelines: Always store the sauce separately from pasta to maintain texture. This ensures your butternut squash pasta sauce remains creamy and doesn’t clump when heated.
Make Ahead Options
This Creamy Vegan Butternut Squash Pasta Sauce is a fantastic candidate for meal prep! You can roast the butternut squash, tomatoes, and onions up to 24 hours in advance. Simply follow the roasting instructions and then store them in an airtight container in the refrigerator. The sauce can also be blended ahead of time and refrigerated for up to 7 days, allowing the flavors to meld beautifully. When you’re ready to serve, just reheat the sauce gently on the stove, adding a splash of reserved pasta water if needed to maintain that silky texture, and toss it with freshly cooked pasta. By prepping the sauce ahead, you’re ensuring a cozy, delicious meal with minimal effort on your busy nights!
Expert Tips for Butternut Squash Pasta Sauce
Roasting Perfection: Ensure that the butternut squash and tomatoes are spread out evenly on the baking sheet. Overcrowding may lead to steaming instead of roasting, affecting flavor.
Blend Smoothly: When blending, add the reserved pasta water gradually for the perfect creamy consistency. Too much liquid can make the sauce overly thin.
Freshness Matters: If using fresh tomatoes instead of canned, choose ripe ones for the best flavor. Avoid over-roasting them, as they can become too mushy.
Taste as You Go: Always taste your sauce before serving and adjust seasoning as needed. Adding more salt or thyme can elevate the flavor of your butternut squash pasta sauce.
Store Properly: To maintain the sauce’s creamy texture when reheating, store it separately from the pasta. This will help prevent overcooking and keep your meal fresh.
