Ingredients

Below, I discuss the ingredients and possible substitutions if you don’t have a specific ingredient. However, if you are looking for the specific measurements of each ingredient, scroll down to the bottom of this article, just above the comments, for the printable recipe card, which includes all the ingredients and the specific amounts of each one.

• Butternut squash – You’ll need a fresh whole butternut squash.
• Water – You’ll need plenty of water to cover the butternut squash in the Instant Pot. You could also use vegetable broth or vegetable stock.
• Butter – I recommend using real butter. You can also use vegan butter or coconut oil.
• Salt – Use Kosher salt to taste.
• Black Pepper – I like to use crushed black pepper from a grinder.
• Cream – You can use sour cream, Mexican Crema, or heavy cream. For a vegan version, you can use coconut cream.
• Garnish – Garnish with chives, fresh rosemary, or basil.

Directions

1. Slice the ends off of the squash. Then cut the squash in half lengthwise and then cut each of those in half widthwise, and then those in 2, until you have a total of 8 pieces.
2. Scoop out the seeds in the center cavity of the squash. Cut them once again in halves, leaving you with a total of 8 sections that are similar in size.
3. Place the trivet inside your Instant Pot and add 2 cups of water.
4. Add the butternut squash to the trivet and close the lid.
5. Set the cooking time for 15 minutes under high pressure.
6. Once cook time has elapsed, release the vent and open the IP when the steam is gone.
7. Remove the squash from the IP, drain, and gently remove the skin from the squash.
8. With a fork or a potato masher, mash the squash until the lumps are gone and you get the texture you would like. If you want it smoother, you can also use an electric mixer, but I suggest leaving a bit of texture in your mashed butternut squash.
9. Continue by placing the squash into a large bowl. Add in the butter so it melts into the mixture.
10. Continue by adding the salt, pepper, and sour cream, mix until combined, and serve.
11. Optional: garnish with fresh rosemary, chives, or basil.

Recipe Tips

• Smooth. If you want a smoother texture, you can also use an electric mixer, but I suggest leaving a bit of texture in your mashed butternut squash.
• Drain Water. When removing the squash from the Instant Pot, be sure to drain well, so the butternut squash is not too watery.

Variations

• Vegan – Use vegan butter and coconut cream instead of real butter and sour cream.
• Maple – Add a 1/4 cup of real maple syrup to the squash.
• Cinnamon – Add a teaspoon of cinnamon to the mashed butternut squash with 1/2 cup brown sugar.
• Pecan – Add chopped pecans to the top of the butternut squash.

Serving Suggestions

• Apple Walnut Cranberry Salad
• Green Bean Casserole
• Sweet Potato Casserole

FAQs

Can I Remove the Skin Before Pressure Cooking?

Yes, you can do that first if you prefer. However, I found it easier to remove the skin after the butternut squash had been pressure cooked.

How Do I Store Mashed Butternut Squash?

Store it in an airtight container for up to 5 days in the refrigerator.

Can I Freeze Mashed Butternut Squash?

Yes, place the butternut squash in a freezer-safe, airtight container and freeze it for up to 3 months.
