  • 1 cup Water (for the pressure cooker)
  • 1 large head Cauliflower, chopped
  • 3/4 tsp Coarse Salt (or 1/2 tsp table salt, or to taste)
  • 1/4 tsp Pepper
  • 1 Tbsp Butter (or more to taste)
  • 1/4 cup Parmesan Cheese, grated

Optional (use any or all!)

  • Roasted Garlic Cloves, to taste
  • 1/4 cup Sour Cream
  • 1/2 cup Bacon (cooked & chopped)
  • More Parmesan to taste
  • 1/4 cup Chives, finely chopped


  1. Pour the water into the inner liner pot of the pressure cooker. Place a steamer basket or trivet in the pot. If using a steamer basket, use one that can hold the entire amount of cauliflower, otherwise, cut the cauliflower slightly larger and put it directly on the trivet.

  2. Add the chopped cauliflower and place the lid on and set the steam release knob to the Sealing position.

  3. Press the Pressure Cook/Manual button or dial and then the + or - button or dial to select 4 minutes. When the cook time is finished, turn off the pot and do a quick release of the pressure/steam.

  4. Remove the cauliflower to a mixing bowl and mash it with a potato masher. Some people like to use an immersion blender, or hand mixer. Whatever you want to use is fine.

  5. Add the salt, pepper, and butter. Mix well.

  6. Add the parmesan and mix well.

  7. Add any other extras you like, mix them in, and serve immediately.
