Instant Pot Mashed Potatoes are creamy and so easy to make. Much faster than cooking on the stove. Cook the potatoes and mash them all in your pressure cooker.


  • 3 lbs russet potatoes (peeled and quartered)
  • 3-4 cups water (enough to just cover the potatoes)
  • 1 1/2 teaspoons kosher salt (divided)
  • 1/4 cup unsalted butter
  • 1/2 cup Milk (nonfat, 2%, or whole milk)
  • 1/2 cup sour cream
  • 1/4 teaspoon ground black pepper
  • chopped parsley or chives (optional for garnish)


  1. Add to Instant Pot - Add the potatoes and water to instant pot. The water should just cover the potatoes. Add 1/2 teaspoon of the salt.
  2. Pressure Cook - Place lid on Instant Pot, set valve to sealing, and cook on manual high pressure for 12 minutes. When done cooking, allow to natural release for 2 minutes, then quick release the pressure.
  3. Mash Potatoes - Drain the potatoes and add them back to the instant pot. With Instant Pot on warm setting, add the butter, milk, sour cream, 1 teaspoon of salt, and 1/4 teaspoon of pepper. Mash and stir potatoes until desired consistency is reach. Taste and adjust salt and pepper as needed.
  4. Serve - Serve potatoes with herbs and a big pat of butter on top, if you'd like. Enjoy!
