How This Recipe Comes Together

Mamaw’s chicken and rice casserole is refreshingly straightforward, which is exactly what makes it so beloved. You’ll start by greasing a 9×13-inch casserole dish and preheating your oven to 400°F. The beauty of this recipe is that everything goes into the dish raw—no pre-cooking required. You’ll cube boneless, skinless chicken breasts into roughly 1-inch pieces, then combine them directly in the casserole dish with water, instant white rice, and three cans of cream soup: chicken, celery, and mushroom. These soups provide all the seasoning and creaminess the dish needs, though you’ll add salt and pepper to taste. After stirring everything together, you’ll arrange pats of butter (a full half-stick if you’re going the authentic Southern route) evenly across the top. The casserole then bakes uncovered for 60 to 75 minutes, during which time the rice absorbs the liquid, the chicken cooks through completely, and the butter creates a golden, flavorful top layer. After a brief cooling period, you’ll have a bubbling, creamy casserole that’s ready to serve straight from the dish.

What You’ll Need

Boneless, skinless chicken breasts (3, cut into cubes) – Cut into roughly 1-inch pieces for even cooking. Don’t worry about being too precise—rustic cubes work perfectly fine.

Water (2 cups) – Provides the liquid the rice needs to cook properly. Some cooks prefer substituting chicken broth for extra flavor.

Instant white rice (2 cups) – The key to this recipe’s simplicity. Instant rice cooks perfectly in the time it takes the chicken to reach a safe temperature.

Cream of chicken soup (1 can, 10.5 ounces) – Adds creamy chicken flavor throughout the casserole.

Cream of celery soup (1 can, 10.5 ounces) – Contributes subtle vegetable notes and additional creaminess.

Cream of mushroom soup (1 can, 10.5 ounces) – Brings earthy, savory depth that balances the other soups perfectly.

Salt and ground black pepper (to taste) – Simple seasonings that let the other ingredients shine. Start conservatively since the canned soups contain sodium.

Butter (½ cup, sliced into pats) – Creates a rich, golden topping as it melts and browns during baking. This is non-negotiable in the traditional version, though you can reduce it if desired.

Step-by-Step Instructions

Prepare your dish and oven – Preheat your oven to 400°F. Grease the sides and bottom of a 9×13-inch casserole dish with butter or cooking spray to prevent sticking.

Gather your ingredients – Lay out everything you’ll need on your counter. This makes the assembly process quick and stress-free.

Cube the chicken – Using a sharp knife or kitchen shears, cut the three chicken breasts into roughly 1-inch cubes. They don’t need to be perfect—just aim for similar sizes so everything cooks evenly.

Combine the base ingredients – Add the cubed chicken, water, instant rice, cream of chicken soup, cream of celery soup, and cream of mushroom soup directly into your prepared casserole dish. Stir everything together thoroughly until well combined and the rice is evenly distributed.

Season to taste – Add salt and ground black pepper according to your preference. Remember that the canned soups already contain salt, so start with less than you think you need.

Top with butter – Slice the half-cup of butter into pats (about 6 to 8 pieces) and arrange them evenly across the top of the casserole mixture. As the casserole bakes, the butter will melt and create a delicious golden layer.

Bake uncovered – Place the casserole in your preheated oven and bake for 60 to 75 minutes. You’ll know it’s done when the rice is tender, the chicken is cooked through to 165°F, and the top has developed a golden color.

Cool before serving – Remove the casserole from the oven and let it rest for 10 to 15 minutes before serving. This resting period allows the sauce to thicken slightly and makes serving much easier.

Best Ways to Enjoy It

Mamaw’s chicken and rice casserole is a complete meal on its own, but certain accompaniments elevate the experience beautifully. Serve it alongside a simple green salad with vinaigrette to add freshness and cut through the richness. Steamed green beans or roasted broccoli provide a crisp vegetable contrast that balances the creamy casserole. Cornbread or dinner rolls are perfect for soaking up the extra sauce on your plate. For a true Southern spread, add coleslaw and sweet tea to round out the meal. This casserole also shines at potlucks and church dinners—simply keep it warm in a slow cooker set to low, or transport it in an insulated carrier. For family-style serving, bring the casserole dish directly to the table and let everyone help themselves, which creates a warm, communal atmosphere.

Storage and Reheating Tips

Refrigerator storage – Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors continue to meld, making leftovers especially delicious.

Important reheating safety – It’s crucial to reheat any rice dish thoroughly, as leftover rice can harbor bacteria that causes foodborne illness even when refrigerated. Always reheat to at least 165°F.

Reheating in the oven – Place portions in an oven-safe dish, add a few drops of water to maintain moisture, cover with foil, and heat at 350°F for 15 to 20 minutes until piping hot throughout.

Reheating in the microwave – Transfer a portion to a microwave-safe dish, add a splash of water, cover, and heat in 1-minute intervals, stirring between each, until steaming hot all the way through. Use a food thermometer to verify it reaches 165°F.

Freezing instructions – This casserole freezes beautifully for up to 3 months. If planning to freeze, cook the recipe in an aluminum pan. Let it cool completely, then cover with a layer of plastic wrap followed by aluminum foil. Label with the date.

Thawing and reheating from frozen – Thaw the casserole overnight in the refrigerator, then reheat in the oven at 350°F for 20 to 30 minutes until heated through, or microwave individual portions until piping hot.

Tricks for Success

Don’t skip the greasing – Properly greasing your casserole dish prevents sticking and makes cleanup much easier after dinner.

Use the right size dish – A 9×13-inch casserole dish (also called a 3-quart dish) is essential. Using a smaller dish will cause overflow; a larger dish will result in dried-out edges.

Embrace the butter – While you can reduce the amount, that full half-stick creates the signature golden, flavorful topping that makes this recipe special. Consider it part of the charm.

Check doneness properly – After an hour, pull out a chicken piece from the center and check with a meat thermometer. It should read 165°F. If not, continue baking in 5-minute increments.

Let it rest – Those 10 to 15 minutes of resting time allow the sauce to thicken and make serving much neater. Resist the urge to dig in immediately.

Customize seasonings – The base recipe is intentionally mild. Feel free to add garlic powder, onion powder, poultry seasoning, or your favorite herbs to boost flavor.

Make it ahead – You can assemble this casserole the night before, cover it tightly, and refrigerate. Add 10 to 15 minutes to the baking time if going straight from fridge to oven.

Creative Twists

Add cheese – Stir in 1 cup of shredded sharp cheddar or Pepper Jack cheese for extra creaminess and flavor. You can also sprinkle cheese on top during the last 15 minutes of baking.

Boost with broccoli – Add 1 to 2 cups of fresh or frozen broccoli florets for color, nutrition, and texture. Mix them in with the other ingredients before baking.

Use rotisserie chicken – Skip cubing raw chicken and use 3 to 4 cups of shredded rotisserie chicken instead. This saves prep time significantly.

Substitute regular rice – Many cooks successfully use regular long-grain white rice (not instant) with the same liquid amounts, though you may need to cover the dish with foil for the first 30 minutes.

Add vegetables – Sautéed onions, diced celery, sliced mushrooms, frozen peas and carrots, or diced bell peppers all work beautifully mixed into the casserole.

Enhance with broth – Replace water with chicken broth for deeper, richer flavor throughout the dish.

Create a crunchy topping – Mix crushed Ritz crackers or panko breadcrumbs with melted butter and sprinkle over the top for the last 15 minutes of baking.

Bacon upgrade – Layer cooked, crumbled bacon over the chicken before adding the soup mixture for smoky richness.

Make it spicy – Add diced jalapeños, cayenne pepper, or red pepper flakes to the mixture, or use cream of jalapeño soup instead of one of the other soups.

Your Questions Answered

Do you cook the rice before adding it to the casserole?

No! The beauty of this recipe is using instant rice, which cooks perfectly during the baking time as it absorbs the liquid in the dish. Adding pre-cooked rice would result in mushy, overcooked rice.

Can I use regular rice instead of instant?

Yes, though results vary. Many cooks report success using regular long-grain white rice with the same liquid amounts, though some recommend covering the dish with foil for the first 30 minutes. Brown rice requires more liquid and longer cooking time—add an extra ½ cup of liquid and extend baking time by 15 to 20 minutes.

When should I add frozen vegetables like peas and carrots?

Add frozen vegetables directly to the mixture before baking—no need to thaw them first. They’ll cook perfectly during the baking time. For fresh vegetables like broccoli, you can add them raw as well, mixing them in with everything else.

Can I substitute cauliflower rice for lower carbs?

Cauliflower rice won’t work as a direct substitute because it doesn’t absorb liquid the same way regular rice does, and it releases a lot of moisture as it cooks. The texture and consistency would be completely different from the intended result.

Why does my casserole turn out soupy?

This usually happens when using regular rice instead of instant rice without adjusting liquid amounts, or when adding extra ingredients that release water (like frozen vegetables that weren’t properly drained). Make sure you’re using instant rice as specified, or reduce liquid slightly if adding wet ingredients.

Can I make this without one of the cream soups?

You can substitute or omit soups based on what you have available. Some cooks use two cans of cream of chicken and skip the celery or mushroom. Others substitute cream of broccoli, cream of potato, or even cream of asparagus with good results.

How can I tell when the chicken is fully cooked?

Use an instant-read thermometer to check that chicken pieces in the center of the casserole reach 165°F. The rice should also be tender when you test it with a fork. If the rice is done but you’re unsure about the chicken, check the thickest pieces with your thermometer.
