Scrumptious Chicken Broccoli Rice Casserole brings caramelized onions, sweet garlic, and sautéed chicken together with long-grain rice and steamed fresh broccoli in a creamy cheddar cheese sauce, all topped with a buttery cracker topping.

This no-canned soup recipe requires a little more effort, but with some helpful tips, even the novice cook can handle this comfort food recipe. My family loves this recipe, and it is always a welcome dish, even with my picky son.
I am not a fan of cream-of-anything soup, including cream of mushroom soup or cream of chicken soup. They taste so bland, so I like to make my sauces from scratch. Hamburger potato casserole, king ranch chicken, and chicken a la king are just a few of our favorite recipes without canned soup.
Ingredient Notes and Substitutions
See the complete list of ingredients on the recipe card below.
- Butter: Unsalted or salted. If using salted butter, reduce the added salt by a pinch or two.
- Chicken: Boneless, skinless chicken breast cut into thin, bite-sized pieces so they cook quickly and evenly.
- Rice: Long-grain like basmati or jasmine. You can substitute brown rice for white rice, but it takes a little longer to cook.
- Broccoli: Fresh or frozen. If using frozen, thaw it and drain any moisture. Frozen broccoli is already blanched.
- Seasonings: Red pepper flakes, onion powder, dried marjoram, dried or fresh thyme, or rosemary
- Milk: Whole or 2%
- Cheese: Cheddar, preferably a good quality sharp cheddar with lots of flavor
- Toppings: Ritz crackers, cornflakes, panko bread crumbs, or Italian breadcrumbs.

Frequently Asked Questions
Yes, you can, but be sure to thaw it and remove any excess moisture. Frozen broccoli is already blanched, so there is no reason to steam it.
That is a great time saver, and these delicious rotisserie chickens are available almost everywhere. Remove the skin and cut about 2 cups of chicken off the bone into bite-sized pieces. Stir it into the cheese sauce with the onions, garlic, broccoli, and rice.
This dish can be prepped up to 24 hours in advance and stored in the fridge. However, hold off mixing the crackers and butter until right before baking.
Remove the casserole from the refrigerator 30 -40 minutes before baking to bring it to room temperature. Then mix and add the buttery cracker topping and bake.

Could you add another vegetable with the broccoli,, like zucchini?
Beth Pierce
Yes, you can but I think I would saute the zucchini just a little bit. Steaming zucchini makes it too soft. You could saute the broccoli as well with the zucchini instead of steaming it.
