Ingredients

  • 3 lbs potatoes, peeled and cut into cubes
  • 2 cups water
  • 4 tbsp butter, melted
  • ¼ cup milk
  • ¼ cup sour cream
  • tsp salt, divided
  • ½ tsp onion powder
  • ½ tsp garlic powder
  • tsp black pepper

Instructions

  • Wash and peel the potatoes. Cut the potato into about sixteen pieces each, making equal sized cubes.
  • Add 2 cups water into the Instant Pot along with about 1 tsp salt and your 3 lbs potatoes. Put the lid on the Instant Pot, then set to MANUAL or HIGH for 8 minutes. Once the cooking cycle is complete, perform a Quick Release. Drain any remaining water.
  • Add the melted 4 tbsp butter, ¼ cup milk and ¼ cup sour cream, then mash the potatoes with a potato masher until smooth and creamy, adding more milk or salt if necessary.
  • Add the rest of the seasonings (½ tsp salt, ½ tsp onion powder, ½ tsp garlic powder, ⅛ tsp black pepper) into the potatoes, and use a spoon to mix until well combined. Garnish with parsley if desired. Enjoy!

Notes

  1. Russet Potatoes: Idaho will also work for this. If you want a chunkier mashed potato that is a little richer, you can try yukon gold!
  2. Water: Using water to cook your potatoes is fine, but if you really want to amp up the flavor without any extra work, try using chicken broth instead.
  3. Butter: I recommend unsalted butter so that you can control the amount of salt in your potatoes. To really make your potatoes taste high end, use a European-style butter that has a higher fat content and will create a richer taste. My favorite brand is Kerrygold!
  4. Milk: Use whole milk for the creamiest potatoes or low fat milk if you are looking for a lighter dinner.
  5. Sour cream: While heavy cream makes potatoes lighter, sour cream gives them more of a creamy and substantial texture, with a slightly tangy taste which I love! If you want a more neutral taste and a fluffier texture, you can substitute this for heavy whipping cream!  
  • After pressure cooking, drain excess water to prevent watery potatoes.
  • Slightly heat your milk, butter, and sour cream before adding to help them absorb better into your potatoes without ruining the texture.
  • Use a hand masher or ricer to give you the best control over how mashed your potatoes are. Don’t use an electric hand mixer or your potatoes could turn out gluey!
  • Salt the cooking water and then season again after mashing for a balanced flavor.
  • Do your best to chop potatoes into uniform cubes so they cook evenly and mash smoothly.
