Why a Casserole?

Well, in the South we LOVE our “throw it all in one dish” casseroles. They are yummy and require less time and prep than making several dishes. They are also almost synonymous with the word “comfort”. Prepare, let it cook while you do other things, then serve it!

Substitutions for Ham and Cheese Casserole Ingredients

This is a pretty basic recipe, and you can easily substitute or add to the ingredients if desired.

  • It calls for packaged, diced ham, but if you have leftover baked ham from another meal, you can use it instead.
  • Cheddar cheese can be changed to any flavor of cheese you prefer. Let your taste buds decide.
  • Spicing it up with a little hot sauce, cayenne pepper, or ground black pepper will add a kick!
  • Broccoli can be used in place of the cauliflower.

Low Carb and High Protein

Following a low carb or keto diet? This dish uses cauliflower in lieu of a pasta or potato, keeping it low carb but still substantial. And the meat and cheese pack a nice punch of protein. The butter and cream keep this dish rich and very filling.

If you’re having this casserole for breakfast or brunch, just serve with some crispy bacon to keep it keto. For dinner, adding a cup of either peas or green beans to this recipe are excellent options.

We hope you’ll enjoy our Keto Ham and Cheese Casserole!

  • 2 cup ham cubed
  • 2 heads cauliflower stems removed and florets separated
  • 1 cups unsalted butter (2 sticks)
  • 3 cups sharp cheddar cheese shredded
  • 2 cups heavy cream
  • 1 tsp salt
  • Sliced green onions for garnish


  • Preheat the oven to 350 degrees. Prepare a 9 x 13 casserole dish with nonstick cooking spray.
  • Fill a large stockpot with water to three-quarters full. Add 1 teaspoon salt. Bring the water to a boil over high heat. 
  • Add the cauliflower florets to the pot, and cook florets for about 10 minutes or until fork tender. Drain the cauliflower well and place in the casserole dish.
  • Sprinkle the ham over the cauliflower and tuck into the cauliflower florets.
  • Meanwhile, in a large skillet, melt the butter over medium-low heat. When the butter is melted, add the heavy cream and bring to a boil, stirring often. Allow to simmer for 10 minutes. 
  • Stir in 2 ½ cups of the cheese into the skillet and stir until melted. Allow the sauce to simmer, stirring often, for an additional 3 to 4 minutes or until the sauce coats the back of a spoon and begins clinging to the sides of the skillet.
  • Pour the sauce over the cauliflower and ham. Top with the remaining cheese.
  • Bake for 45 minutes or until the cheese has melted and the cauliflower begins to brown. Garnish with the sliced green onions.
