Ingredients

The beauty of this recipe is that it relies on straightforward, accessible ingredients. The cream of mushroom soup is the key binding agent here since it provides both flavor and the creamy base for the sauce. Using sharp cheddar rather than mild gives the dish a more pronounced cheesy flavor that holds up well after baking.

2 lbs (900g) boneless, skinless chicken breasts or thighs, cooked and cubed
3 cups (540g) cooked white rice (long-grain works best)
4 cups (360g) fresh broccoli florets (or thawed frozen broccoli, well drained)
2 cans (10.5 oz / 298g each) cream of mushroom soup
1 cup (240ml) chicken broth
1 cup (240ml) sour cream
2 cups (225g) shredded sharp cheddar cheese, divided
1 teaspoon garlic powder
1 teaspoon onion powder
1/2 teaspoon black pepper
1/2 teaspoon salt
1/2 teaspoon paprika
1 tablespoon butter (for greasing the baking dish)
Optional topping: 1/2 cup (55g) crushed buttery crackers (like Ritz) mixed with 2 tablespoons melted butter

Kitchen Equipment Needed

Having the right tools makes this casserole even easier to put together. A large mixing bowl is essential since you’ll be combining a generous volume of filling. A 9×13-inch baking dish is the standard size and ensures the casserole bakes evenly and sets up properly.

1. Le Creuset Enameled Cast Iron Rectangular Baking Dish

This baking dish distributes heat with exceptional consistency, which means the casserole bakes evenly without hot spots or burnt edges. The enameled interior is naturally nonstick and incredibly easy to clean even after the cheesy crust bakes on. It also goes straight from oven to table beautifully.

2. OXO Good Grips Large Mixing Bowl Set

A proper large mixing bowl makes tossing together the casserole filling much easier. The OXO set includes a non-slip base and a pour spout, which is surprisingly handy when transferring the mixture into the baking dish. Having multiple sizes also gives you flexibility for recipes like this.

Step-by-Step Instructions

Step 1: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Give it at least 15 minutes to fully reach temperature before you put the casserole in.
Rub the inside of your 9×13-inch baking dish with 1 tablespoon of butter, making sure to coat the bottom and sides evenly.
Set the prepared baking dish aside while you work on the filling.

Step 2: Cook the Chicken (If Not Already Cooked)

If starting with raw chicken, place your boneless, skinless chicken breasts or thighs in a medium saucepan and cover with cold water or chicken broth for extra flavor.
Bring the liquid to a boil over medium-high heat, then reduce to a simmer. Cook for 15 to 18 minutes, or until the chicken is cooked through with an internal temperature of 165°F (74°C).
Remove the chicken from the liquid and let it rest for 5 minutes before cutting into roughly 1-inch (2.5cm) cubes.
Alternatively, use rotisserie chicken or any previously cooked chicken. Roughly cube or shred it into bite-sized pieces and set aside.

Step 3: Cook the Rice (If Not Already Cooked)

If your rice is not pre-cooked, prepare 1 cup (185g) of dry long-grain white rice according to the package directions. This will yield approximately 3 cups (540g) of cooked rice.
Make sure the rice is fully cooked but not mushy. Slightly undercooked rice is actually fine here since it will continue to cook and absorb moisture as the casserole bakes.
Spread the cooked rice out on a baking sheet for a few minutes to cool slightly and release steam so it doesn’t steam-cook the broccoli when mixed together.

Step 4: Blanch the Broccoli (If Using Fresh)

If using fresh broccoli florets, bring a pot of salted water to a boil. Drop in the broccoli florets and blanch for just 2 minutes. You want them to turn bright green and soften very slightly, but they should still have a firm bite.
Immediately drain the broccoli and transfer it to a bowl of ice water to stop the cooking process. This step preserves the color and keeps the broccoli from becoming mushy in the oven.
After 2 minutes in the ice bath, drain the broccoli thoroughly and pat it dry with paper towels. Excess water will thin out your sauce.
If using frozen broccoli, thaw it completely and squeeze out as much excess water as possible before using.

Step 5: Make the Creamy Sauce

In your large mixing bowl, add the two cans of cream of mushroom soup, the 1 cup (240ml) of chicken broth, and the 1 cup (240ml) of sour cream.
Add the garlic powder, onion powder, black pepper, salt, and paprika to the bowl.
Stir everything together until well combined and smooth. The sauce should be thick but pourable. If it seems too thick, you can add an extra splash of chicken broth (up to 1/4 cup / 60ml).
Add 1 1/2 cups (170g) of the shredded sharp cheddar cheese to the sauce mixture. Reserve the remaining 1/2 cup (55g) for the topping. Stir until the cheese is incorporated into the sauce.

Step 6: Combine the Filling

Add the cubed cooked chicken to the sauce mixture in the bowl. Stir to coat all the chicken pieces.
Add the cooked rice to the bowl and fold it gently into the mixture, making sure the rice gets evenly coated in the sauce.
Finally, add the broccoli florets and fold them in carefully. Try not to break up the florets too much. You want distinct pieces of broccoli throughout the casserole.
Taste the mixture and adjust seasoning if needed, adding more salt or pepper to your preference.

Step 7: Assemble the Casserole

Pour the filling mixture into your prepared, buttered baking dish. Use a spatula or spoon to spread it out evenly, pressing it gently into the corners.
Sprinkle the remaining 1/2 cup (55g) of shredded cheddar evenly over the top.
If using the optional cracker topping, toss the crushed buttery crackers with the melted butter until coated, then scatter the cracker mixture over the top of the cheese layer. This creates an irresistible crispy crust.

Step 8: Bake the Casserole

Cover the baking dish tightly with aluminum foil. The foil traps steam during the first phase of baking, which helps the rice finish cooking and the flavors meld together.
Place the covered casserole in the preheated oven and bake for 30 minutes.
After 30 minutes, remove the foil carefully (steam will escape, so be cautious). Continue baking uncovered for another 15 to 20 minutes, until the top is golden and bubbly, and the edges are just starting to brown slightly.
If the cheese topping isn’t browning to your liking, you can switch the oven to broil for 2 to 3 minutes. Watch it carefully during this step since it can go from golden to burnt quickly.

Step 9: Rest and Serve

Remove the casserole from the oven and let it rest for 5 to 10 minutes before serving. This rest time allows the sauce to thicken up slightly and makes the casserole easier to scoop into clean portions.
Use a large spoon or spatula to serve. The casserole should hold together somewhat but still be saucy and creamy in the center.

Tips for Success

A few small adjustments can make the difference between a good casserole and a great one. The most important thing to keep in mind is moisture management since both the rice and the broccoli can add excess water to the dish if not prepared properly.

Dry the broccoli thoroughly. Whether using fresh or frozen, any excess water will thin the sauce and make the casserole soggy. Pat the broccoli completely dry before mixing.
Grate your own cheese. Pre-shredded cheese is coated with starches that prevent smooth melting. Freshly grated cheddar will give you a far silkier, creamier sauce.
Slightly undercook the rice. If cooking rice fresh for this recipe, pull it a minute early. It will finish cooking in the oven and won’t turn mushy.
Season the sauce before baking. Always taste the sauce mixture before it goes into the dish. Once baked, it’s harder to adjust seasoning.
Don’t skip the foil for the first 30 minutes. The covered baking time helps the casserole cook through evenly without the top drying out.
Let it rest before serving. The sauce thickens as it cools slightly, making portioning much cleaner.
Use thighs for extra flavor. Chicken thighs stay juicier than breasts after baking, especially in a casserole where they’re surrounded by moist filling.

Serving Suggestions

This casserole is a complete meal on its own since it already contains protein, vegetables, and starch in one dish. That said, pairing it with something light and fresh helps balance all that rich, cheesy goodness.

A crisp green salad with a tangy vinaigrette cuts through the creaminess beautifully.
Dinner rolls or warm Buttermilk Biscuits make great vehicles for scooping up any extra sauce.
Roasted vegetables like carrots or asparagus add color and a touch of brightness to the plate.
A simple Broccoli Salad keeps the broccoli theme going while adding a cool, crunchy contrast.
Steamed green beans or sugar snap peas are quick side options that don’t compete with the richness of the casserole.
For a heartier spread, serve alongside Garlic Mashed Potatoes for a true comfort food feast.

Variations to Try

Once you’ve made the classic version, this recipe opens up to tons of delicious variations. The base structure stays the same and you simply swap out or add components to suit your taste or dietary needs.

Use cream of chicken soup instead of cream of mushroom for a lighter, more purely chicken-forward flavor profile.
Swap the cheddar for Gruyere or pepper jack to completely change the flavor character of the dish. Pepper jack in particular adds a welcome kick of heat.
Add diced onion and celery to the filling for extra texture and a more savory, aromatic base.
Make it a tater tot casserole by replacing the cracker topping with frozen tater tots pressed gently into the top before baking for a fun twist that kids absolutely love.
Go vegetarian by omitting the chicken and using vegetable broth, adding extra broccoli, mushrooms, and a can of white beans for protein.
Use brown rice for a nuttier, more nutritious version. Keep in mind that brown rice takes longer to cook and you’ll want to make sure it’s fully cooked before mixing it in.
Add a Dijon mustard swirl (about 1 tablespoon) into the sauce for a tangy depth of flavor that pairs beautifully with cheddar.

Storage and Reheating

This casserole stores beautifully, making it one of the best recipes to have in your meal prep rotation. The flavors actually deepen a bit overnight, so day-two portions are often even better.

Refrigerator: Allow the casserole to cool completely to room temperature before covering. Store covered tightly with plastic wrap or in an airtight container in the refrigerator for up to 4 days.
Freezer: This casserole freezes well. Portion it into airtight, freezer-safe containers or wrap the whole baking dish tightly in plastic wrap followed by a layer of aluminum foil. Freeze for up to 3 months.
Reheating from refrigerator: Place individual portions in a microwave-safe dish and heat on medium power in 60-second intervals, stirring between each, until heated through. To reheat the full casserole, cover with foil and bake at 350°F (175°C) for 20 to 25 minutes until hot and bubbling again.
Reheating from frozen: Thaw overnight in the refrigerator before reheating as described above. If reheating straight from frozen, cover with foil and bake at 350°F (175°C) for 60 to 75 minutes, removing the foil for the last 10 minutes.
To restore creaminess: If the reheated casserole seems a bit dry, stir in a splash of chicken broth or a dollop of sour cream before serving.

Health Benefits of Key Ingredients

This casserole is certainly comfort food, but its core ingredients bring genuine nutritional value to the table. The combination of lean protein, fiber-rich vegetables, and complex carbohydrates makes it a more balanced meal than it might first appear.

Understanding what each ingredient contributes can help you make smart swaps to fit your dietary goals.

Chicken is an excellent source of lean protein, which supports muscle maintenance, satiety, and steady energy levels. A single serving of this casserole provides well over 30 grams of protein.
Broccoli is genuinely one of the most nutritious vegetables you can eat. It’s rich in vitamins C and K, folate, and fiber, and contains compounds linked to anti-inflammatory effects.
Rice provides a steady source of complex carbohydrates for sustained energy. Using brown rice increases the fiber and micronutrient content further.
Cheddar cheese delivers a good hit of calcium and fat-soluble vitamins, which are important for bone health and immune function.
Sour cream contains live cultures and some gut-friendly probiotics, along with calcium and phosphorus.

Frequently Asked Questions

1. Can I use uncooked rice in the casserole?

It is possible to use uncooked rice, but the recipe requires some adjustments. You’ll need to increase the liquid in the recipe significantly (usually by an additional 1 to 1.5 cups / 240 to 360ml of broth) and extend the covered baking time to at least 60 to 75 minutes to ensure the rice fully cooks through. Many people find it easier and more reliable to use pre-cooked rice, which eliminates the guesswork around liquid ratios.

2. Can I make this casserole ahead of time?

Absolutely. This is actually one of the best recipes for making ahead. Assemble the entire casserole, cover it tightly with plastic wrap, and refrigerate for up to 24 hours before baking. When ready to bake, remove it from the refrigerator 20 to 30 minutes before putting it in the oven to take the chill off, then bake as directed. You may need to add 5 to 10 extra minutes to the covered baking time if it’s still cold in the center.

3. Can I use a different type of cheese?

Yes, and it’s a great way to customize the flavor. Sharp cheddar is the classic choice because its bold flavor stands up to baking, but Gruyere, Colby Jack, Monterey Jack, or a mix of any of these all work wonderfully. Pepper jack adds a nice kick of heat. The key is to use a good melting cheese and to grate it fresh from a block rather than using pre-shredded varieties.

4. How do I prevent the casserole from becoming watery?

The most common causes of a watery casserole are excess moisture in the broccoli, using too much liquid in the sauce, or not allowing the casserole to rest after baking. Always dry the broccoli thoroughly before mixing it in. Stick to the measured amounts of chicken broth and sour cream in the sauce. Finally, let the casserole sit for at least 5 to 10 minutes after it comes out of the oven so the sauce can thicken up before you serve it.

5. Can I substitute the cream of mushroom soup for something else?

Cream of chicken soup is the most common and seamless substitute, and many people actually prefer it. You can also make a homemade version by whisking together butter, flour, chicken broth, and milk to make a simple white sauce. Some readers use Greek yogurt or full-fat coconut milk as a base for a lighter version, though these do change the flavor profile slightly.
