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.

Preparation Tips

- Other vegetables to add to this recipe include mushrooms, carrots, and zucchini.

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.

I love casseroles, they are always so filling and smell good when they’re cooking. I love the fact that you’ve added a cracker topping. I’m going to test this out tomorrow.

Thank you, Carole Ann! Enjoy!

I used to rely on those canned soups for dinner until I realized how much better a scratch sauce tastes. Sautéing the chicken with fresh garlic makes the whole kitchen smell way more inviting than the processed stuff.

Cooking from scratch without those canned soups makes a massive difference in how the meal tastes. My family also appreciates a buttery cracker crust because it adds a nice texture to the cheesy rice.
Vanessa
This sounded delicious to begin with, but adding the cheesy, crumbly topping was a genious move for that extra bit of flavour and comfort. A very tasty recipe. We loved it.
