  • 1 large head cauliflower cut into florets ( about 4 cups)
  • 1 small celery root ( also called celeriac) peeled and cut into ½ inch cubes (about 1 cup)
  • 1 cup water
  • Salt and pepper to taste
  • Butter, chives, sour cream, cheese or any other topping of your choice


  • Add a steamer basket to the bottom of the instant pot (silicone or metal). Add one cup of water to the instant pot. Add cauliflower florets and celery root into the steamer basket.
  • Close the lid and set the valve to sealing position. Using the MANUAL setting, cook for 3 minutes on high pressure. Do a quick release to release pressure and steam.
  • Remove steamer basket and cauliflower/celery root from pot. Drain the remaining water from Instant Pot and return cauliflower/celery root back to the Instant Pot. Use an Immersion blender to mix/mash the cauliflower and celery root . If you don’t have an immersion blender you can use a regular hand mixer or a food processor mash the cauliflower and celery root.
