An Easy Way to Make Mashed Potatoes

  • Mashed potatoes are the most popular side dish year-round, and it doesn’t take long for the Instant pot to make them in minutes with minimal prep!
  • For those busy holiday meals, the Instant Pot saves precious time and stovetop space.
  • For larger gatherings (or those who really love mashed potatoes!), cook in batches of mashed potatoes and keep them warm in the crock pot and let everyone help themselves!
  • Serve alongside small bowls of sour cream, salsa, sliced green onions, diced red bell peppers, shredded cheddar cheese, or bacon bits!

Ingredients and Variations

POTATOES: Any potato will do for Instant pot mashed potatoes, but Yukon Golds are extra starchy which means they’ll cook up fluffier than other varieties.

SEASONINGS: Full-fat butter and milk offer the best flavors in mashed potatoes. Sour cream or Greek yogurt can be added to thicken mashed potatoes. Add a little garlic powder for a more savory flavor.

ADD-INS: Stir in a dash or two of Tabasco, cheese sauce, or parmesan cheese.

Pro Tips for Mashed Potatoes

  • Don’t overcrowd the Instant Pot, cook in batches if needed.
  • The warmed milk and melted butter can be whisked together before adding them to the potatoes.

Storing Mashed Potatoes

  • Keep leftover Instant pot mashed potatoes covered in the refrigerator for up to 4 days.
  • Freeze portions in zippered bags for up to 8 weeks. Thawed mashed potatoes will be watery but simply reheat them on the stove or in the Instant pot and that liquid will evaporate.
  • Always add extra butter and adjust the seasonings.
  • Make in advance and reheat in the Instant Pot by adding a little bit of milk and some extra butter.
