Ingredients

  • 4 pounds russet potatoes or Yukon Gold, peeled and sliced
  • 3 cups low sodium chicken stock or broth or water
  • 3 cups water
  • 2 teaspoons kosher salt divided
  • ½ cup unsalted butter
  • ¼ cup half and half or whole milk
  • ½ cup sour cream
  • ½ teaspoon ground black pepper

Instructions

  • Place the prepared potatoes into the Instant Pot. Add the chicken stock and water and one teaspoon of salt. If the liquid is not covering the potatoes, add more water until it does. Give the potatoes a quick stir to make sure the salt is evenly distributed.
  • Secure the instant pot lid and set the pressure valve to sealing. Cook on ‘MANUAL HIGH’ for 12 minutes. When done, switch the valve to ‘QUICK RELEASE’ to release the remaining pressure.
  • Drain the remaining water from the Instant Pot. Use a potato masher to mash the potatoes until they are smooth.
  • In a small saucepan, heat unsalted butter and half and half (or whole milk if using) until the butter melts.
  • Pour the mixture over the potatoes and stir to combine.
  • Add sour cream, one teaspoon kosher salt and freshly ground black pepper. Stir until the ingredients are blended. Taste test and add additional salt and/or pepper if needed.
  • Transfer the mashed potatoes to a large serving bowl. Garnish with additional butter and ground pepper.
  • Serve hot and ENJOY!
