Ingredients for keto cauliflower and cheese casserole including cauliflower, Parmesan, cheddar, cream cheese, chicken broth, butter and seasonings

Ingredients List

  • Cauliflower florets
  • Avocado oil
  • Chicken broth
  • Sharp cheddar cheese
  • Parmesan cheese
  • Cream cheese
  • Dijon mustard
  • Black pepper
  • Garlic powder
  • Onion powder

Substitutions

Cauliflower I used pre-cut and washed cauliflower florets from the produce department to save some time. But you could also use frozen, or cut a head of cauliflower into 1 inch pieces.

Oil The recipe calls for avocado oil, but you could use olive oil or even butter or ghee.

Broth I like the taste of chicken broth in this recipe, but you could substitute vegetable broth for it. You could also use milk or half-n-half if you want even more creaminess.

Cheeses The options are limitless here! I used parmesan, cheddar, and cream cheese, but you could sub in so many other cheeses. Play around with different combos.

Dijon mustard I’m not a fan of mustard in general, but I love Dijon. I think it complements the cheeses in this recipe perfectly, but you could use another mustard or even mustard powder.

How to Make Cauliflower Cheese in Ninja Air Fryer Multi Cooker

I have a Ninja Foodi multi cooker with an air fryer function, so the directions are specific to that. But the recipe could be adapted to other multi cookers, too.

Step 1 Add the cauliflower pieces to the cooking pot of the Ninja Foodi and drizzle with oil. Stir to make sure the oil coats all the pieces. Bake at 375° for 15 minutes.

Step 2 While the cauliflower is cooking, add the remaining ingredients to a bowl and mix until the cream cheese is evenly distributed.

Step 3 When the air fryer shuts off, pour the sauce over the cauliflower. Stir to coat all the pieces and allow the cheese to almost completely melt. Close the lid and bake another 5-10 minutes on 300°.
