  • When the butter melts and they're completely smooth, add 2 cups whole milk. Blend well, then season with salt and pepper to taste.
    Gradually adding milk and seasoning to the mashed potatoes



  • Add even more flavor to your Instant Pot mashed potatoes by including chopped green onions and additional butter!
  • No need to cut your potatoes. After peeling, you can cook them whole in the Instant Pot. That's part of what makes this recipe so convenient!
  • Be careful not to over-mix. If you mix them on too high of a speed or for too long, they will come out gluey! Mix gently.
