Instant Pot Mashed Potatoes

Instant Pot Mashed Potatoes use peeled, quartered russet potatoes pressure-cooked until soft, then mashed with butter, sour cream, and buttermilk for a creamy texture. Seasoned with salt and black pepper, they can be garnished with fresh chives or parsley, offering a smooth, rich side dish prepared efficiently in the pressure cooker.

Description

This recipe begins by quartering and peeling russet potatoes, which are placed in the Instant Pot with water and salt. Cooking on high pressure for 10 minutes softens the potatoes thoroughly. After quick releasing pressure and draining, the potatoes are mashed with whipped butter, sour cream, and low-fat buttermilk, creating a creamy and tangy consistency. Black pepper is added for seasoning to taste.

The resulting mashed potatoes have a smooth texture enhanced by the dairy ingredients. Garnishing with chopped chives or parsley adds a mild herbaceous note and visual appeal. Leftover mashed potatoes can be loosened with reserved cooking water when reheated to maintain creaminess.

Using an Instant Pot speeds up the cooking process while achieving tender, well-cooked potatoes. The balanced acidity from buttermilk and the richness from butter and sour cream contribute to their flavorful profile. This side pairs well with various main dishes.

Ingredients

Servings
  • 2 pounds russet potatoes quartered, peeled
  • 3 cups water
  • 1 1/2 teaspoons kosher salt (divided)
  • 1/3 cup buttermilk low-fat 1%
  • 1/4 cup sour cream I prefer Breakstone’s, light
  • 2 tablespoons butter whipped
  • black pepper to taste, fresh
  • chives for garnish, chopped, or parsley

Instructions

  1. Add potatoes to the instant pot and pour enough water to just cover, season with 1 teaspoon salt.
  2. Cover and cook on high pressure 10 minutes, quick release to check the potatoes are soft. They are done when a sharp knife can easily be inserted through the potato.
  3. Drain and reserve 1/2 cup of the water, add the butter, sour cream and buttermilk, 1/2 teaspoon salt and black pepper and mash with a potato masher.
  4. Adjust salt to taste and keep on warm until ready to serve. It’s best to eat right away, but if you’re eating them later and the potatoes get dry, add the reserved water to loosen them.
  5. Serve garnished with chopped chives or parsley.
