Mashed cauliflower is an excellent low carb alternative to mashed potatoes, and the Instant Pot makes prep and cooking super easy. Cream and Parmesan cheese add brilliant flavor, while fresh chopped parsley adds color. Feel free to change the flavors up with sour cream and chives instead of the cream and parsley.

Scale
  • 1 head cauliflower (medium)
  • 1 1/2 cups water or stock

  • 3 to 4 tablespoons cream (light or heavy, or milk, to taste)
  • 1 to 2 teaspoons fresh chopped parsley

Instructions

  1. Place a trivet in the Instant Pot inner pot. Add 1 1/2 cups of water or stock. Put the garlic in the pot.

  4. Remove the lid and let the cauliflower stand for 2 to 3 minutes to dry slightly.
  5. Carefully remove the cauliflower; discard the water and garlic. Break the cauliflower up and place it in the food processor with the Parmesan cheese and 3 tablespoons of cream or milk.
