Recipe tips and variations
- Instead of cauliflower – Make this easy cauliflower casserole with any steamed vegetable you like. Either replace the cauliflower or try adding broccoli, carrots, asparagus, green beans, or zucchini.
- Not a fan of mozzarella cheese? Try swapping it out for American, cheddar, provolone, or your favorite melty cheese.
- Fresh or frozen cauliflower? You can use fresh or frozen cauliflower in this recipe. Fresh cauliflower must be steamed first and frozen cauliflower should be thawed before it’s added to the casserole dish (no steaming needed).
- Gluten free – Replace the breadcrumbs with gluten free breadcrumbs or omit them completely.
- Looking to add some extra protein? Mix in pre-cooked and shredded chicken or turkey, leftover rotisserie chicken, sausage, diced ham, bacon, or ground beef to this casserole.
Frequently asked questions
What else can I use instead of half and half?
Here’s my favorite 2 substitutions for half and half:
1) You can use 1/2 cup whole milk + 1/4 cup heavy or light cream.
2) You can use 3/4 cup whole milk + 1 tablespoon butter.
(btw you can freeze half and half leftovers!)

You can easily freeze the uncooked or leftover mozzarella cauliflower casserole for up to 3 months in the freezer. Just be sure to thaw it before baking or reheating in the oven.
