Tools

Ingredients

  • 4 pounds russet potatoes - peeled and chopped
  • 1 cup cold water
  • 1 cup butter - plus more for serving
  • 1 cup whole milk - or half-and-half
  • 1 cup sour cream - or plain Greek yogurt
  • Salt - to taste
  • Black pepper - to taste

Instructions

  • Place the metal trivet or silicone basket inside the stainless steel cooking pot of your Instant Pot. Add 1 cup of cold water.
  • Peel the potatoes, then chop them into 1 to 2-inch chunks of equal size. Place the potatoes on top of the metal trivet or inside the silicone steamer basket.
  • Cover and switch the pressure valve to the sealing position. Cook on high pressure for 8 minutes. Note: The Instant Pot will take about 15 minutes to reach pressure before the countdown begins.
  • Switch the steam release valve to the venting position for a quick release. Remove the lid once the valve pops.
  • Drain the potatoes in a large colander and set aside. Meanwhile, remove the inner pot from the Instant Pot, wash and dry well, then transfer the potatoes back to the Instant Pot.
  • Gently heat the butter, milk, and sour cream in a small saucepot set over medium heat until warm. Set the Instant Pot to “warm” and add the dairy mixture to the potatoes.
  • Use a potato masher to mash the potatoes until the desired consistency is reached. Add additional milk or cream, as needed, and season with salt and black pepper to taste.

Notes

  • You may use salted or unsalted butter.
  • The best potatoes for mashed potatoes: starchy potatoes including russet potatoes or Yukon gold potatoes, or some combination of the two.
