Frequently Asked Questions

Can I make this recipe vegetarian?

Absolutely! You can easily make a delicious vegetarian version. Simply omit the sausage and add in some extra veggies like sautéed mushrooms or sun-dried tomatoes for a savory, meaty flavor. A can of drained and rinsed white beans would also be a fantastic addition for some plant-based protein.

My sauce seems too thick. How can I thin it out?

No problem at all! The sauce can thicken as it sits. The easiest fix is to simply stir in a little more of the reserved pasta water, a tablespoon or two at a time, until it reaches your desired creamy consistency.

What’s the best way to store and reheat leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will continue to absorb the sauce, so when reheating, add a splash of broth, milk, or water to a skillet along with the pasta. Warm it over medium-low heat, stirring gently, until heated through.

Can I use a different type of squash?

You sure can! While butternut squash is our star for its sweetness and creamy texture, acorn squash or sweet potato would be wonderful substitutes. Just make sure to roast them until they are completely tender and easily mashable.
