How do I make Mashed Butternut Squash in the Instant Pot?

The instant pot has quickly become a popular cooking device, and for good reason. It can do the work of a slow cooker, pressure cooker, and rice cooker all in one. I love preparing this butternut squash recipe in it! Here is what you will need to do to make it.

Step 1: Prepare the squash

Slice the ends off of the squash. Then cut the squash in half lengthwise and cut each of those pieces in half widthwise. Then, cut those pieces in half, so that you have a total of 8 pieces. Scoop out the seeds in the center cavity of the squash. 

Note: You do not need to peel the butternut squash before cooking it. The peel can easily be removed after it is cooked by using fingers to peel it off or scooping squash off of the skin.

Step 2: Cook the Butternut Squash in the Instant Pot

Place the trivet inside your Instant Pot and add 2 cups of water.Add in the butternut squash on the trivet and close the lid.
Set the cook time for 15 minutes on high pressure. Once cook time has elapsed, hit cancel and allow pressure to release naturally. When valve falls down and steam is gone, open the lid.

Step 3: Mash the Butternut Squash

Remove the squash from the Instant Pot and gently remove the skin. The skin should peel off easily, or you can scoop squash off of the skin. Next, mash the squash with a potato masher or fork until the lumps are gone and texture smooths out. If you want it smoother you can also use an electric mixer, but I suggest leaving a bit of texture into your mashed butternut squash.

Step 4: Add in remaining ingredients, serve & enjoy!

Next, place the squash in a large bowl, add in butter and stir until it melts. Then, add in sour cream and stir until well-combined. Season with salt and pepper to taste. Serve warm with fresh herbs sprinkled on top if desired.
