Notes

  • Add even more flavor to your 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.
