Variations For Easy Cheesy Cauliflower Casserole

Cauliflower bake– Layer the ingredients in a baking dish and bake at 350 degrees F until the top is bubbling and lightly browned.

Broccoli cauliflower casserole– Use half broccoli and half cauliflower.

Chicken cauliflower casserole– Add cubed or shredded chicken from leftover meals or a rotisserie chicken.

Add rice– Mix in cooked white rice, brown rice, or even wild rice.

Add sausage– It should already be cooked beforehand.

Make it healthy– Use low-fat cheeses instead of full-fat.

Add buffalo sauce– For a spicy version.

Add crumbled bacon topping– Do this just before serving.

Add other cheeses– Such as goat, gouda, gruyere, or parmesan.

Loaded casserole– Add chives or green onions, bacon crumbles, and sour cream as toppings.

Add seasonings– Such as Mexican, Cajun, or Italian.

Top with breadcrumbs– After slow cooking, put in a casserole dish under a broiler with bread crumbs and butter for a crispy topping.

Add ranch seasoning– 1 packet should be enough. Omit all other seasonings.

Tips And Techniques

Fresh cauliflower vs. Frozen cauliflower– I used frozen since it cooks faster but fresh can be used too. It will take a bit longer so make note of that for the cooking time. Also, make sure they are all evenly sized.

Adjust seasoning– Add more or less according to your preference.

Layer the cauliflower and cheeses– This ensures that the cauliflower on the bottom doesn’t burn.

How long to slow cook for? For 3 hours on low heat.

Stir half-way through– This prevents the cauliflower and cheese from burning on the bottom of the slow cooker.

Refrigerate– In a sealed container for up to 2 days.

Freeze– I do not recommend freezing because the cauliflower will become mushy and the dairy will separate.

Reheat– In the microwave or on the stovetop.
