Ingredients

  • 3 pounds golden potatoes peeled and sliced
  • 3 cups filtered water
  • 1 cup milk of choice whole milk or 2%
  • 2 teaspoons kosher salt plus more to taste
  • ½ teaspoon ground black pepper plus more to taste
  • 2 tablespoons butter or olive oil
  • Fresh parsley finely chopped (optional, for garnish)

Instructions

  • Place the prepared 3 pounds golden potatoes into your instant pot and pour in the 3 cups filtered water and 1 cup milk of choice.

  • Season generously with 2 teaspoons kosher salt and ½ teaspoon ground black pepper (What I used, you can alter).

  • Give everything a stir, then set the lid on and seal the valve. Press the MANUAL button and set it for 8 minutes. Once the timer is off, allow the pressure to self-release for 10 minutes. Then cover the valve with a thin kitchen towel and turn on the valve so it releases.

Notes

  • Cut potatoes into the same size chunks so they cook evenly.
  • Mash with a masher or ricer for a fluffy texture (avoid over-mashing).
  • Save some cooking liquid to adjust consistency if needed.
  • Season the cooking water well so the flavor goes all the way through.

Storage & Reheating

  • Refrigerator: Store leftovers in an airtight container for up to 5 days.
  • Reheat: Microwave individual servings on high for about 1 minute, or until heated through.
