Dump-and-Bake Cheesy Chicken Breast Casserole puts the rice, cooked chicken, zucchini, creamy sauce, and cheddar in one baking dish, so there’s no separate pot of rice or skillet to deal with. The rice cooks right in the chicken broth and cream of chicken soup, soaking up the savory liquid as the casserole bakes.
The key is keeping the dish tightly covered until the rice is tender. That trapped steam does the cooking, while the final cup of cheddar goes on afterward for a fresh melted cheese layer.
Why This Dump-and-Bake Chicken Casserole Is So Useful
There’s very little prep between you and the oven. The rice doesn’t need boiling, the zucchini doesn’t need sautéing, and using cooked chicken breast makes this an easy way to turn leftovers or rotisserie chicken into another dinner.

For Dump-and-Bake Cheesy Chicken Breast Casserole, the covered baking stage matters more than repeatedly checking the oven. The rice needs both liquid and trapped steam to soften evenly.
You can assemble the casserole ahead, although rice begins absorbing moisture while it sits in the liquid. For the most predictable texture, mix it shortly before baking.
Ingredients for Dump-and-Bake Cheesy Chicken Breast Casserole
The ingredient list is deliberately straightforward, with sharp cheddar supplying much of the flavor.
Creamy casserole base
- 1 can (10.5 ounces) condensed cream of chicken soup: Forms the creamy base.
- 2 cups low-sodium chicken broth: Supplies the liquid needed to cook the rice.
- ½ teaspoon kosher salt
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon paprika
- ¼ teaspoon black pepper
Chicken, rice, vegetables, and cheese
- 1 cup uncooked long-grain white rice: Use regular rice, not instant or quick-cooking.
- 2½ cups cooked chicken breast, diced or shredded: Leftover or rotisserie chicken breast works well.
- 1 medium zucchini, coarsely grated: About 1½ cups.
- 2 cups freshly shredded sharp cheddar, divided: Half goes inside and half over the top.
- 2 tablespoons chopped fresh parsley or chives: Optional.
- Nonstick cooking spray
Why long-grain rice matters
The broth amount and baking time for this cheesy chicken and rice casserole are designed specifically for regular uncooked long-grain white rice.
Brown rice takes considerably longer to cook, while instant rice softens much faster. Switching varieties without adjusting the liquid and baking time can leave the casserole either crunchy or overly soft.
How to Make Dump-and-Bake Cheesy Chicken Breast Casserole
1. Build the sauce directly in the baking dish
Preheat the oven to 375°F and lightly coat a 9 × 13-inch baking dish with cooking spray.
Add the cream of chicken soup, chicken broth, salt, garlic powder, onion powder, paprika, and black pepper directly to the dish. Whisk until the condensed soup is evenly incorporated into the broth.
It’s worth spending an extra few seconds here. A smooth base gives the uncooked rice evenly distributed liquid as it bakes.
2. Add the rice, chicken, zucchini, and cheese
Stir in:
- Uncooked long-grain white rice
- Cooked chicken breast
- Grated zucchini
- 1 cup shredded cheddar
Spread everything evenly through the dish and look around the edges for exposed grains of rice. Push them underneath the liquid so they don’t remain firm while the rest of the Dump-and-Bake Cheesy Chicken Breast Casserole cooks.
3. Cover it tightly
Cover the baking dish tightly with aluminum foil, crimping it firmly around the edges.
Bake at 375°F for 55 to 60 minutes.
Try not to lift the foil repeatedly. Every peek releases some of the steam the uncooked rice needs.
4. Check the rice, not just the timer
Carefully remove the foil and taste several grains from the center of the casserole.
The rice should be tender and most of the liquid should be absorbed. A small amount of moisture is fine because the casserole continues settling during its resting time.
If the rice is still firm, cover the Dump-and-Bake Cheesy Chicken Breast Casserole again and bake for another 5 to 10 minutes.
5. Add the cheesy finish
Once the rice is tender, gently fluff the casserole with a fork rather than stirring aggressively.
Scatter the remaining 1 cup cheddar over the surface and return the dish to the oven uncovered for about 5 minutes, until melted.
For a little extra color, broil for 1 to 2 minutes, watching closely. Let the casserole rest for 5 to 10 minutes before serving.
How to Tell When Chicken and Rice Casserole Is Ready
The rice is a better guide than the clock because oven temperature, baking dishes, and rice brands can all affect cooking time.
| Check | What you’re looking for |
|---|---|
| Rice | Tender through the center |
| Liquid | Mostly absorbed without a watery pool |
| Cheese | Fully melted |
| After resting | Creamy and scoopable, not soupy |
If the rice in your Dump-and-Bake Cheesy Chicken Breast Casserole is still firm, cover the dish again. Continuing to bake it uncovered allows the moisture it still needs to escape.
Why the Foil Is Non-Negotiable
Uncooked rice absorbs the hot broth while steam circulates beneath the foil. If the seal is loose, too much moisture can escape before the grains finish cooking.
That can produce dry edges and crunchy rice even when the casserole has been in the oven for nearly an hour. Press the foil firmly around the rim before baking and reseal it if the rice needs extra time.

Best Chicken Breast for This Cheesy Casserole
You’ll need about 2½ cups cooked chicken breast for Dump-and-Bake Cheesy Chicken Breast Casserole.
Good options include:
- Leftover baked chicken breast
- Poached chicken breast
- Rotisserie chicken with the skin removed
- Meal-prepped chicken breast
- Plain grilled chicken breast
Dice or shred the chicken into bite-sized pieces so it distributes evenly through the rice.
When using strongly seasoned leftover chicken, taste it first and reduce the added salt if necessary.
Easy Cheesy Chicken Casserole Variations
Once you keep the rice and liquid ratio intact, there are several easy ways to change the casserole.
- Chicken and broccoli: Replace the zucchini with small thawed broccoli florets.
- Peas and carrots: Stir in frozen vegetables for another low-prep option.
- Pepper Jack: Replace some or all of the cheddar for extra heat.
- Colby Jack: Use it for a milder cheese flavor.
- Crunchy topping: Add buttered panko or cracker crumbs with the final cheese.
- Herbs: Try thyme, parsley, oregano, or a small amount of rosemary.
- Smokier flavor: Increase the paprika or substitute smoked paprika.
For a richer variation on chicken and rice, Cream Cheese Chicken and Rice One-Dish Dinner uses cream cheese for a heavier, creamier finish.
What to Serve With Cheesy Chicken Breast Casserole

Dump-and-Bake Cheesy Chicken Breast Casserole already combines chicken, rice, zucchini, and cheese, so simple sides work best.
Good choices include:
- Green salad with vinaigrette
- Roasted green beans
- Steamed broccoli
- Roasted asparagus
- Roasted carrots
- Tomato and cucumber salad
- Dinner rolls or biscuits
A crisp or acidic side is particularly useful next to the creamy chicken and rice.
Pro Tips for Better Dump-and-Bake Chicken and Rice
- Keep the rice submerged. Exposed grains can remain crunchy.
- Seal the foil tightly. Trapped steam is essential for properly cooked rice.
- Stick with long-grain white rice. The liquid and timing were developed for it.
- Check the center. Rice around the edges may soften before the middle.
- Fluff gently. A fork separates the cooked rice without crushing it.
- Rest before serving. Those final 5 to 10 minutes help the remaining moisture settle.
Common Problems and Quick Fixes
| Problem | Likely cause | What to do |
|---|---|---|
| Rice is crunchy | Steam escaped or it needs more time | Cover tightly and bake 5–10 minutes longer |
| Casserole is watery | Rice hasn’t absorbed enough liquid | Continue covered baking, then rest |
| Rice is mushy | It baked too long | Begin checking earlier next time |
| Cheese looks oily | It overheated | Add the final cheese only after the rice cooks |
| Flavor is bland | Broth or chicken was lightly seasoned | Adjust seasoning before serving |
| Top won’t brown | Cheese has only melted | Broil briefly and watch closely |
| Leftovers are dry | Rice absorbed more liquid overnight | Add broth before reheating |
Can You Assemble It Ahead?
Yes. Dump-and-Bake Cheesy Chicken Breast Casserole can be assembled several hours before dinner, covered, and refrigerated.
The tradeoff is that uncooked rice begins absorbing liquid before baking, which can make the finished grains softer. If you assemble it early, start checking for tenderness a little sooner.
For the most predictable texture, mix everything shortly before it goes into the oven.
Storage and Reheating
Refrigerator
Cool leftover Dump-and-Bake Cheesy Chicken Breast Casserole and refrigerate it in an airtight container for 3 to 4 days.
Reheating individual portions
Add a small splash of chicken broth to each serving, cover loosely, and microwave until hot.
Reheating in the oven
Transfer leftovers to an oven-safe dish, add a little broth, and cover with foil. Reheat at 350°F for about 20 to 25 minutes.
The added broth replaces some of the moisture the rice absorbs while refrigerated.
Dump-and-Bake Cheesy Chicken Breast Casserole FAQs
Do I need to cook the rice first?
No. Regular uncooked long-grain white rice goes directly into the casserole and cooks in the broth and condensed soup.
Can I use instant rice?
Not as a direct substitute. Instant rice cooks faster and has different liquid requirements.
Can I use brown rice?
Not without changing the recipe. Brown rice requires more cooking time and different liquid proportions.
Can I use raw chicken breast?
This Dump-and-Bake Cheesy Chicken Breast Casserole is specifically written for cooked chicken breast. Substituting raw chicken changes both the preparation and food-safety requirements.
Can I replace cream of chicken soup?
Cream of mushroom or cream of celery can provide a similar creamy structure, although either will change the flavor.
Why is my rice still crunchy?
Check the foil seal first. Escaping steam can prevent the rice from cooking properly. Cover tightly and continue baking if enough moisture remains.
Can I leave out the zucchini?
Yes. You can omit it or replace it with another suitable vegetable.
When should I add the cheese?
Mix 1 cup into the casserole before baking. Add the remaining 1 cup only after the rice is tender.
A Better Reason to Keep a Casserole in the Dinner Rotation
Dump-and-Bake Cheesy Chicken Breast Casserole works because the shortcuts don’t interfere with how the rice cooks. Broth and condensed soup provide the liquid, a tight foil seal holds in steam, and using cooked chicken keeps the preparation simple.
Once the rice is tender, the last layer of cheddar finishes the dish without another pan or cooking step. After a short rest, you get creamy rice, plenty of chicken, soft zucchini, and melted cheese in every scoop.

Dump-and-Bake Cheesy Chicken Breast Casserole
- Total Time: 1 hr 15 min
- Yield: 6 servings 1x
Description
Dump-and-Bake Cheesy Chicken Breast Casserole combines uncooked long-grain rice, cooked chicken breast, zucchini, creamy chicken soup, broth, and sharp cheddar in one baking dish. The casserole stays covered while the rice cooks, then gets a final layer of melted cheese for an easy one-dish dinner.
Ingredients
1 can (10.5 ounces) condensed cream of chicken soup
2 cups low-sodium chicken broth
½ teaspoon kosher salt
½ teaspoon garlic powder
½ teaspoon onion powder
¼ teaspoon paprika
¼ teaspoon ground black pepper
1 cup uncooked long-grain white rice
2½ cups cooked chicken breast, diced or shredded
1 medium zucchini, coarsely grated, about 1½ cups
2 cups freshly shredded sharp cheddar cheese, divided
2 tablespoons chopped fresh parsley or chives, optional
Nonstick cooking spray
Instructions
1. Preheat the oven to 375°F. Lightly coat a 9 × 13-inch baking dish with nonstick cooking spray.
2. Add the condensed cream of chicken soup, low-sodium chicken broth, kosher salt, garlic powder, onion powder, paprika, and black pepper directly to the prepared baking dish. Whisk until the condensed soup blends smoothly into the broth with no large lumps remaining.
3. Add the uncooked long-grain white rice, cooked chicken breast, grated zucchini, and 1 cup of shredded sharp cheddar. Stir until everything is evenly distributed throughout the creamy liquid.
4. Spread the mixture into an even layer. Check around the sides of the dish and push any grains of rice sitting above the liquid back underneath so they can cook evenly.
5. Cover the baking dish very tightly with aluminum foil, crimping it securely around the edges to trap steam.
6. Bake covered at 375°F for 55 to 60 minutes. Avoid repeatedly lifting the foil during baking because releasing steam can interfere with the rice cooking properly.
7. Carefully remove the foil and check several grains of rice from the center of the casserole. The rice should be tender and most of the liquid should be absorbed. If the rice remains firm, cover the dish tightly again and bake for another 5 to 10 minutes before checking once more.
8. Once the rice is tender, gently fluff the casserole with a fork rather than aggressively stirring it with a large spoon.
9. Sprinkle the remaining 1 cup shredded cheddar evenly over the surface. Return the casserole to the oven uncovered for approximately 5 minutes, or until the cheese has completely melted.
10. For a lightly browned cheese topping, place the casserole under the broiler for 1 to 2 minutes after the cheese melts. Watch continuously to prevent burning.
11. Remove the casserole from the oven and let it rest for 5 to 10 minutes. Garnish with chopped parsley or chives if desired, then scoop and serve.
Notes
Rice: Use regular uncooked long-grain white rice. Instant rice, quick-cooking rice, and brown rice have different liquid requirements and cooking times and should not be substituted directly.
Chicken: This version uses cooked chicken breast. Leftover baked chicken, poached chicken, meal-prepped chicken breast, or rotisserie breast meat all work well.
Foil: A tight seal is essential. The trapped steam helps cook the uncooked rice. If too much steam escapes, the rice can remain firm even after the expected baking time.
Doneness: Use the rice rather than the clock as your final test. The grains should be tender and most of the liquid should be absorbed.
Pan differences: Glass, ceramic, and metal baking dishes can cook at slightly different rates, so actual baking time may vary.
Rice still firm: If the casserole still contains moisture, cover it tightly again and continue baking for 5 to 10 minutes at a time until the center is tender.
Zucchini: Coarsely grated zucchini can be replaced with suitable vegetables such as thawed broccoli, peas, corn, or mixed vegetables.
Cheese: Sharp cheddar gives the casserole a stronger cheese flavor, but Colby, Colby Jack, Monterey Jack, mozzarella, or Pepper Jack can also work.
Crunchy topping: After the rice has finished cooking, add buttered panko or cracker crumbs with the final cheese and bake uncovered until golden.
Make ahead: The casserole can be assembled ahead and refrigerated, but the uncooked rice will begin absorbing liquid while it sits. Start checking for doneness earlier if it has rested in the liquid for several hours.
Storage: Refrigerate cooled leftovers in an airtight container for 3 to 4 days.
Reheating: Add a splash of chicken broth to prevent the rice from drying out. Cover and reheat in a 350°F oven for approximately 20 to 25 minutes, or microwave individual portions until hot.
Freezing: Rice texture can soften after freezing and thawing, so refrigeration provides the most reliable leftover texture.
