This butternut squash pasta sauce is easy to make and comforting and delicious to eat. A few ingredients create a silky sauce, which pairs wonderfully with your favorite pasta. Cubes of butternut squash are tossed with olive oil and sage roasted along with garlic cloves, then pureed and thinned with half and half and some water. We also like to add toppings—anything from plenty of grated Parmesan to toasted nuts to chicken cutlets. It’s the kind of cozy dinner that has everyone asking for seconds. 

Make a batch and freeze portions to use for nights when you need a fast meal.

Serving Suggestions

Pasta

Our butternut squash pasta sauce has never met a pasta it didn't get along with. Generally, we serve it tossed with a short pasta that has ridges or is shaped so that sauce clings onto it, like penne rigate, cavatappi, farfalle, or fusilli. It's also great with stuffed pasta, such as cheese or meat ravioli. If you serve it with a skinny long pasta like spaghetti, you’ll notice you get more sauce-to-pasta ratio.


Toppings

Our recipe calls for serving the sauce and pasta topped with Parmesan cheese, toasted walnuts and sage leaves. If you want to try something different:

  • Play to the sauce's creamy side by adding a dollop of fresh ricotta to each potion, maybe topped with some hot pepper flakes.
  • Crumble cooked bacon over each portion.
  • Swap the nuts for another toasted nut such as almonds.


What to Serve With the Pasta

Make this dish dinner by rounding out the meal with a salad or a side of roasted vegetables. Add protein by using the sauce for cheese ravioli or meat ravioli, or serving the pasta with simple sautéed chicken cutlets, pork cutlets, or crumbled  Italian sausage.

Cool the sauce to room temperature; then transfer to airtight containers, leaving 1 inch of space. Freeze for up to three months.

Defrosting and Reheating

When ready to use, place containers upside-down under hot tap water to help release frozen blocks of sauce. Place blocks in a saucepan; cover and reheat over medium-low, adding water to thin if necessary.

Frequently Asked Questions

Can you use precut butternut squash for this recipe?

Yes, we generally use a whole butternut squash when we make this sauce because it’s more economical, but you can use precut butternut squash if you prefer.


Is this butternut squash pasta sauce bland?

No, our butternut squash pasta sauce is not bland. Cutting the butternut squash into chunks and roasting them amps up the sweet vegetal flavor of this favorite winter squash. And roasting garlic alongside the squash, then pureeing them together means the sauce has plenty of rich roasted garlic flavor as a backdrop to the squash. Half and half adds richness and a luscious mouthfeel to the sauce, and serving it with toasted nuts and plenty of Parmesan adds to the savory fall flavors of the dish.
