Some dinners never go out of style, and Chicken Broccoli Rice Casserole is one of those dependable favorites in our home.
Creamy rice, tender chicken, broccoli, and melted cheese baked together in one dish always feels comforting and complete.
I first started making this casserole when I needed something hearty, easy, and family-friendly on busy evenings. It quickly became a regular request because it uses simple ingredients, feeds everyone well, and tastes just as good the next day.
Why You’ll Love This Recipe
This recipe brings together protein, vegetables, and a comforting starch in one easy pan. Every bite has creamy rice, savory chicken, tender broccoli, and rich cheesy flavor.
It is also wonderfully practical for home cooks. Many ingredients can be pre-cooked or leftover, and the oven does most of the final work.

This recipe makes six generous servings, depending on portion size. It can easily be doubled for larger families, potlucks, or meal prep.
Ingredients You’ll Need
For the Casserole
- 3 cups cooked rice
- 2 cups cooked chicken, shredded or diced
- 4 cups broccoli florets, chopped
- 2 cups cheddar cheese, shredded
- 1 cup mozzarella or Monterey Jack cheese, shredded
- 1 small onion, finely diced
- 2 cloves garlic, minced
For the Sauce
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 cup chicken broth
- 1/2 cup sour cream
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1/2 teaspoon paprika
For the Topping
- 1 cup breadcrumbs or crushed buttery crackers
- 2 tablespoons melted butter
- 2 tablespoons grated Parmesan cheese
Optional Add-Ins
- 1/2 teaspoon Dijon mustard

Rotisserie chicken works especially well in this recipe and saves time on busy nights. Leftover cooked rice is also a great shortcut.
Pro Tips
Use cooked rice that has cooled slightly. Freshly steaming rice can make the casserole softer than needed.
Cut broccoli into bite-sized pieces so it blends evenly throughout the casserole. Smaller pieces are often more family-friendly too.
Shred your own cheese when possible. Freshly shredded cheese usually melts smoother than packaged varieties.
Do not overcook the sauce before baking. A slightly loose sauce thickens more in the oven.
Let the casserole rest for 10 minutes after baking. This helps it set for cleaner servings.
For families with younger children, chop the broccoli smaller and use mild cheddar for a gentler flavor.
Tools You’ll Need
- 9×13-inch baking dish
- Large mixing bowl
- Medium saucepan
- Whisk
- Wooden spoon or spatula
- Knife
- Cutting board
- Measuring cups
- Measuring spoons
- Small bowl for topping
A glass or ceramic baking dish works especially well because it holds heat nicely and serves beautifully at the table.
Substitutions and Variations
Use brown rice, wild rice blend, or cauliflower rice instead of white rice depending on preference. Cooking times stay similar if ingredients are already cooked.
Swap chicken for turkey, ham, or cooked ground turkey. This recipe is a great way to use leftovers.
Use Greek yogurt instead of sour cream for a lighter tangy option.
Cheddar can be replaced with Colby, Monterey Jack, mozzarella, Swiss, or pepper jack. Mixing cheeses creates extra flavor.
If you need gluten-free options, use gluten-free flour and gluten-free crackers or breadcrumbs.
For a vegetable-packed version, add mushrooms, carrots, peas, spinach, or sautéed peppers. Cook watery vegetables first if needed.
Add hot sauce, cayenne, or pepper jack cheese for a spicier casserole.
For a lower-carb version, reduce the rice and add extra broccoli or cauliflower rice.
Use cream of chicken soup instead of homemade sauce for a quicker shortcut version.
Top with extra cheese during the last 10 minutes of baking for an even cheesier finish.
Make Ahead Tips
This casserole is perfect for planning ahead on busy days. You can cook the rice, shred the chicken, chop the broccoli, and prepare the sauce up to one day in advance. Store each component separately in the refrigerator until ready to assemble.
You can also fully assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. This makes dinnertime much easier when schedules are full.
If baking from chilled, allow the dish to sit at room temperature for about 20 minutes while the oven preheats. This helps the center cook more evenly.
For meal prep, bake the casserole fully and portion leftovers into containers for easy lunches.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
A prepared dish helps prevent sticking and makes cleanup much easier after dinner.
Step 2: Prepare the Broccoli
Bring a pot of water to a boil. Add the chopped broccoli and cook for 2 minutes until bright green and slightly tender.
Drain immediately and set aside. This quick blanch keeps the broccoli vibrant and prevents it from becoming too firm in the casserole.
Step 3: Cook the Onion and Garlic
In a medium saucepan, melt 3 tablespoons butter over medium heat. Add the diced onion and cook for 4 to 5 minutes until softened.
Stir in the minced garlic and cook for 30 seconds more. This builds a flavorful base for the sauce.
Step 4: Make the Sauce
Sprinkle the flour over the onion mixture and stir well. Cook for 1 minute, then slowly whisk in the milk and chicken broth until smooth.
Continue cooking for 4 to 6 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon.
Step 5: Finish the Sauce
Reduce the heat to low. Stir in the sour cream, salt, black pepper, garlic powder, paprika, and Dijon mustard if using.
Mix until smooth and creamy. Taste and adjust seasoning if needed.
Step 6: Combine the Casserole
In a large mixing bowl, combine the cooked rice, chicken, broccoli, and half of both cheeses. Pour the warm sauce over the mixture.
Stir gently until everything is evenly coated. The mixture should look creamy but not dry.
Step 7: Fill the Baking Dish
Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle the remaining cheddar and mozzarella over the top.
In a small bowl, mix breadcrumbs or crushed crackers with melted butter and Parmesan. Sprinkle evenly over the cheese layer.
Step 8: Bake the Casserole
Bake uncovered for 25 to 35 minutes, or until hot and bubbling around the edges. The topping should be golden brown and crisp.
If you would like more color, broil for 1 to 2 minutes at the end while watching closely.
Step 9: Rest Before Serving
Remove the casserole from the oven and let it rest for 10 minutes. This helps it firm up slightly for easier scooping and serving.
The flavors also settle nicely during this short resting time.
Step 10: Serve
Spoon onto plates and serve warm. Add extra black pepper, chopped parsley, or hot sauce if desired.
This casserole works beautifully as a complete meal or with simple sides.
Serving Suggestions
Serve this casserole with a crisp green salad and vinaigrette for freshness and balance. The light salad contrasts nicely with the creamy dish.
Add warm dinner rolls, garlic bread, or biscuits for a cozy family dinner. Bread is always welcome with casseroles.
Serve smaller portions beside roasted vegetables for a balanced plate. Carrots, asparagus, or green beans work especially well.
Offer hot sauce or red pepper flakes at the table for those who enjoy extra heat.
Use leftovers with sliced tomatoes or cucumber on the side for an easy lunch plate.
For potlucks, keep the casserole warm and garnish with parsley before serving.
Leftovers and Storage
Allow leftovers to cool slightly before storing. Cover the baking dish tightly or transfer portions to airtight containers and refrigerate for up to 4 days.
To reheat, microwave individual servings in short intervals until hot. Stir halfway through if needed for even heating.
For larger amounts, cover the casserole and warm in a 350°F oven until heated through. Add a splash of milk if it seems thick after chilling.
You can freeze cooled portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating.
