This Cheesy Broccoli Casserole is made from scratch with tender broccoli florets, an easy cheese sauce, and a buttery crumbs topping.
- Fresh broccoli best in this recipe
- Boil or steam broccoli just until tender-crisp (do not overcook)
- Frozen broccoli can be used in place of fresh but the casserole will be softer (defrost first)
- Whether using fresh or frozen, drain very well to keep the sauce from getting watery.
- Cheese sauce can be made with any cheese you’d like
- Dry mustard adds a bit of depth, if you don’t have any, add a small dash of Worcestershire or dijon mustard
- Buttery round crackers (like Ritz) can be replaced with any kind of crackers or even chips
- Panko bread crumbs can be used, add a bit of extra butter to the topping
You can swap out other veggies (cauliflower or asparagus) for some or all of the broccoli. Add in ham or leftover Chicken Breasts to make this a main dish.
Pasta or rice are great additions but do soak up some of the sauce so if you’re adding rice, I’d suggest using a Broccoli Rice Casserole or Broccoli and Cheese Casserole recipe to get the best ratios.
How to Make Broccoli Casserole
This casserole is as easy as 1,2,3!
- Boil or steam broccoli until tender-crisp.
- Prepare the cheese sauce (per recipe below).
- Toss with broccoli.
- Top with buttery crumbs and bake until golden and bubbly.
To Make Ahead of Time
Prepare as directed keeping the topping in a separate container. Cover and refrigerate up to 48 hours.
To bake remove from the fridge 30 minutes before baking. Bake 15 minutes and stir. Add crumb mixture and bake an additional 20 minutes or until hot and bubbly. You may need to add up to an additional 10 minutes to heat through.
To reheat broccoli casserole, cover with aluminum foil and bake in the oven at 350 degrees.
In the microwave (without foil of course) reheat until heated through. The crumbs won’t be as crisp in the microwave.
