Ingredients Method Notes

Ingredients
  

  • or Basic Butter
  • 3 lbs russet potatoes peeled and cut into 2-inch cubes
  • 1 ¼ cups chicken broth vegetable broth can be used for a vegetarian option
  • 2 tablespoons 28 g unsalted butter
  • ½ teaspoon sea salt plus additional to taste after cooking
  • ¼ cup warmed whole milk or cream or more to reach desired consistency
  • Add-ins for Sour Cream & Chive
  • ½ cup finely chopped chives lightly packed
  • ½ cup sour cream or plain Greek yogurt
  • Add-ins for Garlic Rosemary
  • 8 whole peeled garlic cloves to cook with the potatoes
  • ½ teaspoon freshly minced rosemary

Method
 

  1. Place the cubed potatoes, broth, butter, and ½ teaspoon of sea salt into the Instant Pot. For the Garlic Rosemary version, include the garlic cloves at this stage.
  2. Secure the lid and ensure the vent is set to sealing. Select Manual High Pressure and cook for 10 minutes. Note that the Instant Pot requires approximately 10 minutes to reach pressure before the cooking timer begins.
  3. After cooking, allow the pressure to naturally release for 5 minutes, then carefully release any remaining pressure. Stir in the warmed milk or cream along with your selected flavorings, and mash until the potatoes achieve a smooth texture. Adjust seasoning to taste and serve immediately.
