The Best Instant Pot Mashed Potatoes

Recipe by Bailey Sissom

This instant pot mashed potatoes recipe makes rich, creamy mashed potatoes in a fraction of the time. Yukon gold potatoes, warm milk, butter, and garlic come together for fluffy, smooth, restaurant-level mashed potatoes perfect for any holiday dinner or weeknight meal.


  • Total Time40 minutes
  • Yield6 servings 1x

Ingredients

  • Yukon gold potatoes (3 lbs | 1.36 kg), peeled and cut into chunks
  • Garlic cloves (4 cloves | ~12g), peeled
  • Water (1.5 cups | 360 ml)
  • Unsalted butter (4 tablespoons | 57 g), divided
  • Warm milk (½ cup | 120 ml)
  • Heavy cream (¼ cup | 60 ml)
  • Kosher salt (1 teaspoon | 6 g, plus more to taste)
  • Black pepper (¼ teaspoon | 1 g)

Instructions

  1. Add the water (1.5 cups) to the Instant Pot and place the Yukon gold potatoes (3 lbs) and garlic cloves (4 cloves) inside.
    Seal the lid and set the valve to sealing. Cook on manual high pressure for 10 minutes, then perform a quick pressure release.
  2. Drain the potatoes completely, then return them and the garlic cloves (4 cloves) to the warm pot.
  3. Add unsalted butter (2 tablespoons) and mash until the potatoes begin to break down.
  4. Slowly stir in the warm milk (½ cup) and heavy cream (¼ cup) until smooth and creamy. Add the remaining unsalted butter (2 tablespoons) and continue mashing until fully incorporated.
  5. Season with kosher salt (1 teaspoon, or to taste) and black pepper (¼ teaspoon). Adjust cream and butter as needed for your desired texture.
  6. Transfer to a serving dish and top with additional unsalted butter (as desired) before serving.

Notes

If your garlic cloves are large, cut them in half before cooking so they mash evenly and disappear into the potatoes. 

Steamer basket optional: Lifting potatoes above the water can create a fluffier texture, but they can cook directly in the pot if you do not have one. 

Skin on potatoes work for a rustic mash; scrub well.
