Instant Pot Garlic Herb Mashed Potatoes

The fluffiest, creamiest, and most buttery mashed potatoes are yours without having to babysit a pot of boiling water, and with an easy option to keep them warm as long as needed. Mashed potatoes used to be a big hassle, and this recipe changed the game!

Ingredients

  • 3 pounds russet potatoes
  • 6 whole cloves garlic peeled
  • 2 teaspoons salt
  • 1/2 teaspoon dried rosemary
  • 1/2 teaspoon dried thyme
  • 3 cups water
  • 1/4 cup unsalted butter
  • 1/4 cup sour cream
  • 2 ounces cream cheese
  • fresh rosemary, thyme, chives, or parsley for optional garnish

Instructions

  • Peel and chop potatoes into pieces 1-2 inches thick, then place in the Instant Pot. Add garlic and sprinkle with salt, rosemary, and thyme. Pour water on top, cover, seal, and cook for 8 minutes on manual/high pressure. While the potatoes cook, melt the butter in a large liquid measuring cup, then add the sour cream and cream cheese and set aside.
  • When the 8 minutes are up, use the quick release function to vent the steam, and leave the pot on “keep warm.”
  • Carefully open the lid and lift out the insert. Drain the potatoes, return them to the pot, and mash thoroughly with a potato masher or large spatula. This should be easy - they’ll be very soft and ready to fall apart.
  • Scoop in the butter, sour cream, and cream cheese, and mix vigorously with a spatula to incorporate. Taste and add more salt, if desired. Garnish as desired and serve!

Notes

  • Either reduced or full-fat sour cream and cream cheese are fine, use whichever you prefer.
  • The finished potatoes are fine on the “keep warm” setting for at least an hour. If it’s much longer than that, or if you’re reheating from the fridge, add a splash of milk and stir well to lighten things back up.
