Cheesy chicken broccoli rice casserole combines seasoned chicken, cooked white rice, broccoli, a creamy two-soup sauce, and Colby Jack under a bubbling cheese topping. It is a practical family dinner that uses familiar ingredients and can be assembled in one skillet before going into a 9-by-13-inch dish.
The chicken is cooked first so its doneness is certain, while frozen broccoli can go straight into the mixture. Use three cups of already cooked rice, melt two cups of cheese into the sauce, and reserve the final cup for the top.
Ingredients for Chicken Broccoli Rice Casserole
For the chicken, use 2 boneless skinless chicken breasts, 1 tablespoon olive oil, 1 teaspoon onion powder, 1 teaspoon garlic powder, 1 teaspoon seasoned salt, and salt and pepper to taste.
The sauce needs two 10.5-ounce cans cream of chicken soup, one 10.5-ounce can cream of mushroom soup, 1/2 cup heavy cream, and 3 cups shredded Colby Jack cheese, divided. Complete the casserole with 12 ounces frozen broccoli and 3 cups cooked white rice.
- Cooked rice: Measure after cooking. Raw rice will not have enough liquid or time to cook correctly in this casserole.
- Frozen broccoli: Add it frozen; it heats through during the covered bake.
- Colby Jack: Two cups enrich the sauce and one cup creates the browned top.
- Condensed soups: Use them straight from the cans rather than diluting with water.
- Chicken: Cook to 165°F before cutting it into bite-size pieces.

How to Make Cheesy Chicken Broccoli Rice Casserole
- Prepare the oven and dish. Heat the oven to 350°F and lightly grease a 9-by-13-inch baking dish.
- Season the chicken. Coat the breasts with olive oil, onion powder, garlic powder, seasoned salt, pepper, and only as much additional salt as needed.
- Cook the chicken. Heat a large skillet over medium-high. Cook the breasts for 4 to 5 minutes per side, until browned and 165°F in the thickest part. Rest briefly, then cut into bite-size pieces.
- Make the sauce. Lower the skillet to medium. Add cream of chicken soup, cream of mushroom soup, and heavy cream. Stir until smooth and hot, then melt in 2 cups Colby Jack. Season to taste.
- Combine. Fold the chicken, frozen broccoli, and 3 cups cooked rice into the sauce until every spoonful is evenly coated.
- Assemble. Spread the mixture in the prepared dish and scatter the remaining 1 cup cheese across the top. Cover with foil.
- Bake. Bake for 30 to 40 minutes, until hot and bubbling throughout. Remove the foil near the end if you want more color, then rest 5 to 10 minutes before serving.

Use Cooked Rice, Not Raw Rice
The recipe calls for three measured cups of cooked white rice. Raw rice needs a precise amount of free liquid and sustained covered heat, neither of which this thick cream sauce provides. Using it raw can leave hard grains while drawing moisture away from the casserole.
Day-old refrigerated rice is convenient because its grains are firm and separate. Fresh rice also works; let excess steam escape for a few minutes before folding it into the sauce. Break up any cold clumps so the filling heats evenly.

Cook Juicy Chicken Before Assembly
Chicken breast thickness varies, so temperature is more reliable than time alone. Cook over medium-high heat for about 4 to 5 minutes per side and check the thickest part for 165°F. If one end is much thicker, pound the breast to a more even thickness before seasoning.
Rest it briefly before cutting to retain juice. The chicken is already fully cooked when it enters the casserole; the oven reheats it rather than finishing raw meat. Avoid cooking far beyond 165°F in the skillet because the pieces spend another half hour in the hot sauce.
Make the Cheese Sauce Smooth
Lower the skillet temperature before adding the condensed soups and cream. Stir them together until no streaks remain, then add two cups of cheese in several handfuls. Moderate heat melts Colby Jack evenly without making the sauce oily.
The sauce should look thick because frozen broccoli releases a little water during baking. If it seems impossibly stiff, add one or two tablespoons of milk or chicken broth. Taste before adding salt: condensed soup, seasoned salt, and cheese all contribute plenty.
Using Frozen Broccoli Successfully
Frozen broccoli saves preparation and can be mixed in without thawing. Separate any pieces frozen into a solid clump and cut unusually large florets so they distribute throughout the pan. Keeping the dish covered for most of the bake traps enough steam to heat them through.
If using fresh broccoli, cut it into small florets and blanch for 2 minutes before draining thoroughly. Raw large florets may remain too firm by the time the already-cooked chicken is hot. Whether fresh or frozen, excess surface water can thin the sauce, so do not add ice crystals from the bottom of the bag.
Topping and Serving
Reserve a full cup of Colby Jack for the top rather than mixing all three cups into the sauce. This creates an even golden layer and makes the casserole easy to portion. Uncover for the final 5 to 10 minutes if you prefer light browning, or broil very briefly while watching continuously.
Serve with a crisp salad, roasted carrots, or sliced tomatoes for contrast. The casserole already contains protein, starch, and broccoli, so a fresh simple side is enough. A sprinkle of parsley or sliced scallions adds color after baking.
Troubleshooting
- Casserole is dry: The rice may have been overmeasured or the dish baked uncovered. Measure three cooked cups and keep the foil on.
- Center is cold: Return the covered dish to the oven and check in 5-minute intervals.
- Sauce is watery: Avoid loose ice from the broccoli bag and let the casserole rest 10 minutes before serving.
- Chicken is tough: Stop skillet cooking at 165°F and cut it only after a short rest.
- Top is pale: Uncover near the end or broil briefly, keeping the dish close under observation.
Make Ahead, Storage, and Reheating
Assemble the casserole up to one day ahead, cover tightly, and refrigerate. A cold dish usually needs extra oven time, so keep it covered and verify that the center is fully hot before serving. If using a glass dish, follow its manufacturer's guidance about moving directly from refrigerator to oven.
Refrigerate cooked leftovers for up to 3 days. Reheat covered in a 325°F oven or warm individual portions in the microwave with a small splash of milk. The casserole can be frozen, but rice and cream sauce are at their best freshly baked; if freezing, wrap airtight, thaw overnight in the refrigerator, and reheat covered.
Conclusion
Cook seasoned chicken breasts to 165°F and cut into pieces. Stir condensed soups with cream over medium heat, melt in 2 cups Colby Jack, and fold in chicken, frozen broccoli, and 3 cups cooked rice. Top with the remaining cheese and bake covered at 350°F for 30 to 40 minutes.
Frequently Asked Questions
- → Can I use uncooked rice in this casserole?
No. Use three cups of already cooked white rice. Raw rice does not have the correct liquid ratio or cooking environment in the thick sauce.
- → Do I need to thaw frozen broccoli?
No. Add it frozen after separating clumps and discarding loose ice crystals. The covered casserole provides enough heat and steam.
- → Can I assemble the casserole ahead?
Yes. Cover and refrigerate it for up to one day. Bake until the center is steaming hot, allowing extra time because the dish starts cold.
- → How long do leftovers keep?
Store cooled leftovers airtight in the refrigerator for up to 3 days. Reheat covered with a small splash of milk if the rice has absorbed sauce.
