  • 2 stalks celery
  • 1/2 large yellow onion
  • 2 cloves garlic
  • 1 head cauliflower *
  • 3 tablespoons salted butter
  • 1 pound breakfast sausage
  • 8 ounces cream cheese
  • 1 pound chicken cooked and shredded
  • 1 cup cheddar cheese shredded
  • 1 cup Colby Jack cheese shredded
  • 1 teaspoon salt
  • 1/2 teaspoon ground black pepper
  • 1/2 teaspoon paprika
  • 1 cup water


  • Wash and chop or mince the celery, onion, and garlic; also wash and chop the cauliflower.
  • Pre-heat the Instant Pot in sauté mode.
  • Add the butter to your Instant Pot, and let it melt.
  • Sauté the celery, onion, and garlic for about 3 to 5 minutes.
  • Add the sausage in with your veggies and allow it to brown, crumbling it up with the veggies.
  • Add the cream cheese and shredded chicken in with your vegetable mixture, and mix together well.
  • Put the cauliflower, shredded cheeses, salt, pepper, and paprika on top of the vegetable mixture in the Instant Pot.
  • Add a cup of water.
  • Put the lid on your Instant Pot.
  • Turn off the sauté function, press Manual, and set your timer for 8 minutes; allow a natural pressure release.
  • When it's done, stir the casserole together... If there's extra water, you may need to turn the sauté function back on and let it cook down just a little bit.
  • You can top it off with chopped basil or parsley if desired. Serve and enjoy!



*While you can use already riced cauliflower, I recommend using fresh for this recipe. Frozen riced cauliflower can have extra water, which changes the entire texture/consistency of this casserole.
