This deliciously creamy butternut squash pasta sauce is a super easy vegan, healthy, and flavorful recipe. This meal can be a pasta sauce or soup with roasted butternut squash, tomatoes, garlic, and onion.
Perfect for picky eaters, this butternut squash sauce is an autumnal dream! This pasta sauce captures all fall flavors and is creamy, healthy, and vegan.
This perfect butternut squash pasta sauce is great:
For picky eaters. You’ll love this butternut squash sauce if you have picky eaters. They’ll never know it’s made with so many good-for-you ingredients.
When you buy a lot of autumn produce, this recipe was inspired by a trip to my local farmer’s market. I couldn’t resist all the fall produce, so when I came home with way more butternut squash than we could eat, I roasted it up to create this sauce.
Craving Autumnal flavors. I love the combination of tomato and butternut squash in this pasta sauce as the acidity of the tomato cuts through the sweetness of the butternut squash and makes this pasta sauce savorier and challenging to stop eating. The flavors of these vegetables (technically fruits) balance each other very well.

Ingredients for butternut squash sauce
- Olive oil. To flavor the sauce and for roasting the squash and tomatoes.
- Butternut squash. You’ll need 2 ½ cups of cubed butternut squash. To save time, you can even buy pre-cut squash cubes.
- Tomatoes. I usually use 3-4 tomatoes in this sauce and cut them into large chunks for roasting.
- Onion. For added flavor, I use half a large onion. Again, you need to slice it into large chunks for roasting.
- Garlic cloves. You’ll need two, and leave the skins on while they roast and peel them after. For an extra garlicky flavor, feel free to add more.
- Salt. Just a little to enhance the flavors of the other ingredients.
- Seasonings. A pinch of dried chili pepper flakes, dried oregano, and freshly ground black pepper.
How to make butternut squash tomato pasta sauce
- Chop your veggies into chunks and toss them with some oil and salt.
- Place them on a sheet pan in a single layer and bake at 350ºF for about 20-25 minutes. Roasting the vegetables gives them an extra layer of flavor.
- When the veggies are roasted, peel the garlic and then blend the tomato, garlic, onion, and butternut squash with some pasta water (if you’re making pasta go with the sauce) or use water or veggie stock. Use a regular blender or an immersion blender (affiliate link).
- Transfer it to a saucepan, add more oil, and season with black pepper, chili pepper flakes, and a pinch of salt. Warm on the stovetop until heated through. Taste for seasoning and adjust if needed.
- Add to pasta, use as a soup base, or store covered in the refrigerator until ready.

Storage and freezing tips
Storage: The butternut squash sauce can be stored in an airtight glass container in the refrigerator for 3-4 days. When ready to use, reheat in the microwave or on the stovetop.
Freezing: Let the sauce cool completely and place it in a freezer-safe container, leaving space at the top for the sauce to expand. You can also store it in freezer bags. It should last for up to 3 months in the freezer. To defrost, let it sit in the refrigerator overnight and reheat it in the microwave or stovetop.
- Serve it with wheat pasta, gluten-free pasta, or chickpea pasta.
- Toss it with zucchini noodles.
- Try using it as a pizza sauce.
- Enjoy it as a thick and creamy soup with a grilled cheese sandwich on the side or croutons on top.
- Add a tablespoon of nutritional yeast and smoked paprika to the sauce, and serve it as a cheese sauce for chips and nachos.
- Finish it with a big cream dollop or Mexican crema
Additional recipe tips
Have fun with the ingredients. Make this recipe your own and add more tomato, onion, or other ingredients.
Roast your veggies in a single layer. This will help them roast evenly. If the pan is overcrowded, the veggies will steam instead of roast. And you want all the flavor that roasting brings out.
Line your sheet pan with parchment paper. This makes for easy cleanup.
Hide the garlic. Ensure you hide the garlic cloves under the tomatoes or butternut squash pieces, so they don’t burn.
Carefully transfer the roasted veggies to a stand blender. The veggies will be hot right out of the oven, so be careful. Use a heat-proof blender, or if the veggies are too hot to handle, wait for them to cool slightly.
Blend in batches. Depending on the size and power of your blender, you may need to blend the sauce in batches.
Finish the pasta with fried sage, fresh basil, or chopped cilantro. Roasted walnuts or almonds (affiliate link) will be great here, as well as roasted chickpeas.
Add some liquid. If the mixture is too thick for your blender, add more water or veggie stock to help it blend into a smooth sauce.
