How to Make Creamy Cauliflower Casserole

Step 1: Prepare the Cauliflower

Cut the cauliflower into bite-sized florets and steam or boil until just tender. Avoid overcooking, as excess moisture can make the casserole watery.

Step 2: Make the Cheese Sauce

In a saucepan, combine cream cheese, shredded cheddar, heavy cream (or Greek yogurt), garlic, and seasonings. Stir until smooth and creamy.

Step 3: Add the Protein

If using bacon or diced ham, cook until crisp and stir into the sauce. You can also use cooked shredded chicken or turkey.

Step 4: Assemble

Place the cooked cauliflower in a baking dish, pour the cheese sauce over the top, and mix gently to coat.

Step 5: Bake

Sprinkle with extra cheddar and Parmesan cheese, then bake until bubbling and golden brown.

Step 6: Garnish

Finish with chopped parsley or chives before serving.
