Every fall I look forward to cooking with butternut squash. The sweet, nutty flavor and creamy texture of this winter squash is completely irresistible! My family loves this Instant Pot Butternut Squash Soup, as well as Roasted Butternut Squash and I make both often throughout the fall and winter seasons.

I use my Instant Pot multiple times a week, so of course I had to try cooking butternut squash in it. After a bit of recipe testing, I’m happy to report that cooking butternut squash in the Instant Pot is not only fast and easy, but it makes perfectly tender and delicious butternut squash. 

I’m including directions for how to cook butternut squash cubes, as well as quartered unpeeled squash. My preferred method is to cook quartered squash because it’s fast and easy to prep, since you don’t have to peel or dice the squash. But I know that the pre-cut cubes of butternut squash that you can purchase at the grocery store are a time-saver, so I wanted to be sure to include instructions for how to cook cubed squash too.

How to Use Instant Pot Butternut Squash

There are so many ways to serve Instant Pot butternut squash!

It makes a delicious side dish. You can serve it as is or you can mash the squash. I love it with just a pat of butter and some salt and pepper. For added sweetness, add a drizzle of pure maple syrup, a sprinkle of brown sugar, or a spoonful of Honey Butter. Or, for savory squash, sprinkle on some Parmesan cheese.

Add it to salads, grain bowls or pasta dishes. Or stir cooked squash cubes into a pot of chili.

Instant Pot butternut squash can also be used in your favorite butternut squash recipes that use cooked butternut squash. Here are a few to try:
