Mashed potatoes are one of the top comfort foods, but they often seem like a bit of a time-consuming project that you have to properly plan for. However, if you're using a pressure cooker instead of waiting for water to boil and then the potatoes to cook, making mashed potatoes is no longer a chore. These Instant Pot mashed red potatoes are a snap to put together because the pressure cooker cuts the cooking time considerably—they're ready in about 20 minutes.

The recipe calls for red-skinned potatoes, but feel free to use Yukon Gold (they make for creamy mashed potatoes, too) or another kind of potato in this recipe. The amount of butter can be adjusted as well, or use olive oil, ghee, or coconut oil in place of the butter. Similarly, you can use water, but potatoes taste even better if cook them in a low-sodium chicken or vegetable stock. Fresh herbs, such as parsley and/or chives, are a classic add-in for these Instant Pot mashed potatoes.

If you don't have an Instant Pot or similar multi-cooker, another brand will work as well. Just follow the manufacturer's guidelines for setting and releasing steam.

Why Did My Mashed Potatoes Turn Out Gummy?

It's an all-too-common problem: gummy mashed potatoes. This happens when the starches in the potatoes become overworked during the mashing process. It's also important to make sure the potatoes are drained well and are as dry as possible before mashing. To completely avoid any possibility that your potatoes will turn out gluey, many people are devoted to using a ricer to guarantee fluffy mashed potatoes.


  • This recipe is made with red-skinned potatoes which are low in starch, or "waxy." For fluffier mashed potatoes, use russets or baking potatoes, which are high in starch, or use a medium starch potato such as Yukon Gold or long whites.

Recipe Variations

Mashed potatoes are a blank slate and are easily adaptable. Here are some variations.

  • Replace the cream or milk with coconut milk or broth.
  • Replace half of the potatoes with cauliflower for a lighter mash lower in carbs.
  • Add 1 to 2 cups of chopped cooked cabbage or kale to the pot for a traditional Irish-inspired colcannon.
  • Replace one-third to one-half of the potatoes with peeled and cubed rutabagas for a delicious mashed potato and rutabaga combination.
