  • 2.5 lbs. potatoes whole and peeled
  • 1/2 stick butter
  • 5 Tbsp. salt
  • 2 cups whole milk
  • green onions for garnish
  • additional butter for extra flavor
  • additional salt & pepper to taste


  • Place 2.5 lbs peeled whole potatoes (Russet potatoes or Yukon golds) in your Instant Pot after it has already been heated.
  • Add water to the pot enough to cover the potatoes halfway, but not all of the way.
  • Replace the lid of your pot and cook on pressure for 12 minutes.
  • Once done cooking and after releasing the pressure, CAREFULLY (you can see here we're using oven mitts!) remove the inside pot and drain your potatoes, then return to the cooker.
  • Use a hand mixer on medium to mash the potatoes until they are well mashed. Add in 1/2 a stick of butter 1 tablespoon at a time while continuing to blend.
  • When the butter melts and the potatoes are completely smooth, add 2 cups whole milk. Blend well, then season with salt and pepper to taste.



  • Add even more flavor to your Instant Pot Mashed Potatoes by including chopped green onions and additional butter!
