Ingredients

  • 3 pounds Russet potatoes, peeled and quartered
  • 1 cup water
  • ½ cup unsalted butter
  • 1 cup milk
  • ½ cup sour cream
  • Kosher salt and black pepper to taste

Instructions

  • Add the potatoes, water, and a couple pinches of salt to the Instant Pot, lock the lid in place, and set to manual, high, and 10 minutes cook time.
  • Add the butter and milk to a small pot and bring to a simmer on the stovetop. Remove from the heat and set aside.
  • When the timer goes off, turn the valve to “quick release.” Drain any remaining water and transfer the potatoes to a large mixing bowl. Mash the potatoes with a potato masher until smooth.
  • Slowly add the hot milk and butter to the potatoes and stir with a spatula to combine. Add the sour cream and stir. Season to taste with salt and black pepper.
