Chicken broccoli rice casserole is a cozy one-dish dinner that combines tender chicken, fluffy rice, and broccoli in a creamy cheddar sauce. It is easy to prep, bakes in one pan, and works beautifully for weeknights or meal prep.
This recipe is ideal when you want comfort food without a lot of cleanup. If you like easy baked chicken dinners, compare this to our cheesy loaded chicken potato bake on a night when you want potatoes instead of rice.

Why This Recipe Works
Cooking the broccoli briefly before baking keeps it bright green and tender instead of mushy. Combining sour cream with cream of chicken soup and cheddar creates a stable sauce that coats the rice and chicken evenly.
Baking everything together lets the flavors meld while the cheese turns golden and bubbly on top. For another broccoli-forward bake, try our creamy chicken quinoa broccoli casserole when you want a lighter grain base.
Ingredients
- 2 cups cooked chicken breast, shredded or diced
- 1 cup uncooked rice, or 3 cups cooked rice
- 2 cups broccoli florets, chopped
- 1 can (10.5 oz) cream of chicken soup
- 1/2 cup sour cream
- 1 cup shredded cheddar cheese, divided

How to Make Chicken Broccoli Rice Casserole
1. Preheat and prep the pan
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
2. Cook the rice
If using uncooked rice, cook it according to package directions until tender. If using leftover rice, break up any clumps before mixing.
3. Blanch the broccoli
Cook the broccoli in boiling water for 2 to 3 minutes until bright green and slightly tender. Drain well.
4. Make the creamy sauce
In a large bowl, whisk together the cream of chicken soup, sour cream, half of the cheddar cheese, milk, garlic powder, salt, and pepper until smooth.
5. Combine the filling
Add the cooked chicken, rice, and broccoli to the sauce. Stir gently until everything is evenly coated.
6. Assemble and bake
Spread the mixture into the prepared baking dish. Top with the remaining cheddar and breadcrumbs if using. Bake for 25 to 30 minutes until hot and bubbly.
7. Rest and serve
Let the casserole rest for 5 minutes before serving so the sauce sets slightly.
Tips for the Best Casserole
- Drain broccoli well so the casserole does not turn watery.
- Use freshly shredded cheddar for better melting.
- Season the sauce before adding the chicken and rice.
- Cover with foil if the top browns too quickly.
