Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Cauliflower florets – The star of this dish. Cauliflower absorbs flavor beautifully and develops a tender, buttery texture when baked.

Butter – Adds richness and helps the sauce cling to the cauliflower.

Cream cheese – Creates the creamy base that gives the casserole its signature velvety texture.

Heavy cream – Adds smoothness and binds the cheeses into a perfectly thick, luscious sauce.

Cheddar cheese – The main cheese component, bringing sharp, tangy flavor and that golden, bubbly topping everyone loves.

Mozzarella cheese – Melts beautifully, giving the casserole its gooey, stretchy texture.

Garlic powder – Enhances the overall savory flavor of the sauce with just a touch of warmth.

Onion powder – Adds depth and balances the creaminess with a subtle hint of sweetness.

Salt and black pepper – Essential for seasoning and bringing out all the flavors in the dish.

Fresh parsley – Optional, but adds a pop of freshness and color to the finished casserole.
