This Butternut Squash Pasta Sauce is a super easy recipe that’s creamy, flavorful and packed with butternut squash and tomatoes. You can serve it as a pasta sauce or use it as a base for soups!
If you have picky eaters in your house, you’ll love this butternut squash sauce. They’ll never know it’s made with so many good-for-you ingredients!
This recipe was inspired by a trip to my local farmer’s market. I couldn’t resist all of 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!
Some of our other favorite ways to use butternut squash include:
- Curried Red Lentil and Butternut Squash Soup
- Roasted Butternut Squash Soup in two steps
- Butternut Squash Soup with grilled cheese croutons
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. The flavors of these vegetables (that are technically fruit!) 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 normally use 3-4 tomatoes in this sauce and I cut them into large chunks for roasting.
- Onion. For added flavor, I use half of a large onion. Again, you just 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 on 350ºF for about 20-25 minutes.
- When the veggies are roasted, peel the garlic and then blend together the tomato, garlic, onion, and butternut squash with some pasta water (if you’re making pasta to go with the sauce) or use water or veggie stock.
- Transfer it to a saucepan, add some more oil and season with black pepper, chilli 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 to use.

Storage and freezing tips
Storage: The 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 then place it in a freezer-safe container, leaving some 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 then reheat it in the microwave or on the 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 some nutritional yeast and smoked paprika to the sauce, and serve it as a cheese sauce for chips and nachos.
Additional recipe tips
- Have fun with the ingredients. Make this recipe your own and add more tomato or 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 clean up.
- Hide the garlic. Make sure 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.
Add some liquid. If the mixture is too thick for your blender, you can add more water or veggie stock to help it blend into a smooth sauce.
