Easy mashed sweet potatoes using the Instant Pot are a colorful and tasty alternative to the classic pale side dish. The electric pressure cooker transforms the dense tubers into soft and tender pieces that are easy to mash.

The pressure built up in the Instant Pot elevates the cooking temperatures while using hot steam to soften the cells of the potato within minutes. The result is tender taters that can be made into a creamy puree. Sweet potatoes already have a plentiful amount of natural sugar, so I add warm holiday spices like cinnamon and nutmeg to balance the taste. It’s like dessert in a bowl but without guilt!
All that’s needed for this pressure cooking technique is a few pounds of chopped sweet potatoes and water. Additional mix-ins are up to you, as this recipe makes for a versatile base to create a sweeter or more savory flavor.
Sweet potato size matters
With various types of sweet potatoes available at the grocery store, I recommend Garnet sweet potatoes. They have bright orange flesh that cooks up to be very sweet and moist. Other types like purple, Jewell, Japanese, Okinawa, and Hannah can be used. However, they may have a slightly different texture.
For quick and even cooking of the sweet potatoes, cut them into 1-inch pieces. Anything smaller, and they’ll crumble apart too easily.
Tips for pressure cooking
Insert the steamer basket into the bottom of the pot, then put the cut potatoes on top. Elevating the ingredient will allow the steam to cook the potatoes evenly. All you need is 1 cup of water for 2 pounds of sweet potatoes to get the pot up to pressure and properly cooked.
Getting the right texture
Using a potato masher, it’s important to mash the potatoes with butter. The fat helps to coat some of the starch particles so that the texture stays creamy but not gluey. If you want a smoother consistency, puree in a food processor for a few seconds. I use this technique for my sweet potato casserole recipe.
While dispersing the seasonings more evenly as you mash, add the spices and salt with the butter to save you an extra step. For a lighter product, fold in some cream, milk, non-dairy milk, or coconut milk until the desired consistency is reached.
A drizzle of pure maple syrup or honey would also be tasty. For those with a sweet tooth like me, you can add a pinch or two of brown sugar.
This mashed sweet potato recipe can be made ahead of time and reheated right before serving on the stovetop or in the microwave. Using an electric pressure cooker is an efficient alternative to other methods. If you don’t have time to make baked sweet potatoes, this Instant Pot method is a great option.

Pressure cooker time
Using the high-pressure setting, tender sweet potatoes that can be easily flaked with a fork cook relatively quickly. The high pressure of around 13 psi plus the steam heat can cook a whole unpeeled sweet potato in 15 to 16 minutes. For cut and cubed pieces, 10 minutes is plenty of time.
