Chicken Broccoli Casserole is one of those simple, dependable dinners that always come in clutch.
Mom has been makingย this cheesy chicken and broccoli casserole for years. While broccoli was not always a favorite, now we love it all, and our kids are learning to love broccoli sooner than we did.
This dish is creamy, cheesy, and packed with tender chicken and broccoli, then finished with a buttery breadcrumb topping that bakes up golden and crisp.
What makes this recipe so special is how easy it is to throw together with simple ingredients, especially if you use leftover chicken or rotisserie chicken. It is perfect for busy weeknights, bringing dinner to a friend, or making ahead when you know the week is going to be hectic.
If you love easy comfort-food casseroles like this, you should also try Chicken Spaghetti, Funeral Potatoes, and Cheesy Hashbrown Casserole.
Why you’ll love it + Why it works:
- Great for leftovers. Using cooked chicken makes it fast and perfect for leftovers or rotisserie chicken.
- Meal prep fav. It is great for meal prep and reheats well for leftovers.
- Foolproof creamy sauce. Cream of chicken soup and mayo make it rich, smooth, and reliably creamy every time.
- Crispy topping every time. Buttered breadcrumbs brown up golden and crunchy, not soggy.

Kristyn’s Recipe Tips
- Drain the broccoli really well so the casserole does not turn watery, extra moisture can thin the sauce.
- Rotisserie chicken works great here and makes prep so fast.
- Spread the sauce evenly all the way to the edges so every serving gets plenty of creamy topping.
- If you want extra crunch, add a little more breadcrumbs or broil for 1 to 2 minutes at the end, watching closely.
