Like potatoes, cauliflower has a mild flavor that can be easily upgraded with the addition of some cheese. Need proof? Meet our loaded cauliflower casserole.
This side is essentially a veggie-forward version of a loaded baked potato, in casserole form. By steaming the cauliflower for 20 minutes before folding in the cheese mixture, the florets soften significantly, resulting in a texture that bears resemblance to mashed thick potatoes.
According to our Test Kitchen, this is not necessarily a "light" recipe. The combination of cream cheese, sour cream, and two types of shredded cheeses make the casserole quite rich, but the cauliflower lightens the whole dish up to make it a justifiably indulgent side.
Best of all, this dish can be made up to three days ahead, and the leftovers keep well. When you're getting ready to serve, just pop it in the oven, top with bacon for crunch and chives for freshness, and you're well on your way to an easy Sunday dinner.

Ingredients for Loaded Cauliflower Casserole
To make this casserole, you'll need:
- Cooking spray: To keep the casserole from sticking to the pan. (Hello, easy cleanup.)
- Cauliflower: Buy heads of cauliflower and cut into florets, or grab prepackaged florets if you're short on time.
- Cream cheese: Full-fat is the way to go here for extra creaminess, but low-fat is a good substitute.
- Sour cream: Full-fat sour cream or low-fat sour cream if preferred.
- Garlic powder: For added complexity and flavor.
- Sharp Cheddar cheese: A classic sharp, cheesy flavor that's always comforting and delicious.
- Pepper Jack cheese: Creamy with a hint of spice that livens up the rich sauce.
- Cooked bacon slices: Crisp, salty finish for this loaded casserole. If going vegetarian, eliminate completely or try swapping with a panko breadcrumb topping or fried shallots for extra crunch.
- Fresh chives: A mild, oniony flavor that freshens and brightens the dish.

Frequently Asked Questions
-
Frozen cauliflower often contains more liquid as it defrosts than fresh cauliflower. Fresh is best in this case, but if using frozen, thaw and pat dry before using.
-
If you find your cauliflower looks moist after steaming, pat dry with a paper towel to absorb excess moisture before folding into the cream cheese mixture.
