How To Make Mashed Potatoes In The Instant Pot
Making mashed potatoes in the instant pot is not only very easy but they turn out so perfect and creamy every time.
You could take the time to peel all your raw potatoes but I prefer to leave the peel o and wash them. I think the peeling process is much easier when the potatoes are fully cooked.
Start by filling the inner pot with 1 cup of water. I recommend using a steamer basket like this one but if you don’t have one be sure to place your trivet in the bottom before you stack the washed potatoes inside.
Pressure Cook Whole Potatoes
Place the lid on the pot using the manual or pressure cook setting on high pressure for 8-12 minutes depending on the size of the potatoes you’re cooking. This will take about 15 minutes for the Instant Pot to come to pressure. When the cooking time is complete allow the pressure to naturally release.

When the lid can safely be removed, carefully remove the potatoes using the steamer basket handle. Turn the Instant Pot off and clean the inner pot, return it back to the instant pot.
Allow the potatoes to cool for a few minutes then run the potatoes under cold running water for 1 minute. Using your fingers or a small knife to easily peel the skins off.
Turn the Instant Pot back on to keep warm, pour half of the milk in the bottom of the inner liner place peeled potatoes back in along with divided butter, black pepper, sea salt, garlic powder and, onion powder.
To “mash” the potatoes you can use a traditional handheld potato masher or a hand mixer. I prefer the hand mixer for a thick but creamy texture. Either way I “mash” I do it right in the stainless steel inner pot. No need to dirty another bowl. As you mash the potatoes add the rest of the milk a little bit at a time until you’ve reached the desired consistency.
Top with another pad of butter and some fresh chopped parsley. If you have a glass lid, it comes in handy when using the keep warm setting until you are ready to serve.

How To Freeze Mashed Potatoes
To freeze mashed potatoes in individual portions I prefer to use my Souper Cube Trays. This allows me to freeze individual portions I can use for an easy side dish or use multiple cubes for a family-sized meal. Frozen mashed potatoes can be stored for up to two months in a freezer bag or up to 6 months if vacuum sealed.
How To Reheat Frozen Mashed Potatoes
Oven: Place mashed potatoes in a glass baking dish and bake at 350° for 15 minutes and stir. Continue to bake for another 15 minutes or until the mashed potatoes are warmed through completely.
Microwave: Place cubes of frozen potatoes in a microwave-safe dish and microwave in one-minute increments for about 5 minutes stirring frequently to be sure the potatoes are warmed through completely.
Stovetop: Place frozen cubes in a pot and heat on low to medium heat. Stirring frequently until the potatoes are hot and ready to serve.
