  • 3 pounds Yukon Gold Potatoes , or Russet potatoes
  • 1 cup water * you want about an inch of water in the bottom of your pressure cooker, so you may need to add a little more depending on the size of pressure cooker you use
  • 1/4 teaspoon salt , or more, to taste
  • 1/4 cup milk
  • 1/4 cup sour cream
  • 1/4 cup butter
  • 1 teaspoon chicken bouillon paste , optional, for flavor


  • Wash the potatoes, peel them (optional) and cut into quarters. 
  • Add water, potatoes and salt to the instant pot. 
  • Secure the instant pot lid and close the pressure release valve. Select manual/High pressure and cook at high pressure for 10 minutes. 
  • When the timer beeps, allow the pressure to naturally release for 3-5 minutes, and then quick release the remaining pressure.
  • Carefully open the lid. Add the milk, sour cream, butter, bouillon paste, and salt and pepper.
  • Mash everything combine, but be careful not to over mash the potatoes, which leads to gummy mashed potatoes instead of fluffy mashed potatoes.
  • Taste and add more seasonings, as needed. 


Make Ahead Tip:
Mashed potatoes can stay in the instant pot on "keep warm" for 1-2 hours. Gently stir them and taste them before serving. They may need another splash of milk and a little salt or additional seasonings.
*You can double or triple this recipe for a 6 or 8 quart instant pot. The water amount and cooking time will stay the same. Just be sure you don't go above the "fill" line".
