  • 5 lbs Potatoes cubed or quartered
  • 2 teaspoon kosher salt
  • 2 tablespoon butter
  • 1 teaspoon white or black pepper (or to taste)
  • 1 to 1 ½ cups heavy cream half & half or milk, (I use heavy cream) See Note*


  • Wash, peel and cube potatoes. Put potatoes in Instant Pot {6 Quart} and cover with water until potatoes with 1 inch of water. Add in salt. Close and lock lid. Turn vent to closed. Set on Manual High for 8 minutes.
  • When cooking time is complete. Quick release (manually open to release pressure) the valve. I like to place a damp cloth over mine. 
  • Drain water off potatoes in a collander. Add back into Instant Pot.
  • Add butter, heavy cream, and pepper, if desired, to potatoes. Beat with a hand mixer or potato masher (I use electric hand mixer). Taste and adjust salt if needed.


*I start with 1 cup of cream and add to that until the potatoes are the consistancy desired. ** If you want to make these on the stove top, boil potatoes until fork tender. Usually about 45 minutes.
