Ingredients You’ll Need

Here’s everything that goes into this creamy, cheesy masterpiece:

2 cups cooked chicken, diced
2 cups broccoli florets
2 cups cooked rice
2 cups shredded cheddar cheese
1 can cream of chicken soup
½ cup milk
¼ cup sour cream
1 teaspoon garlic powder
1 teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
½ cup crispy fried onions (optional but highly recommended)

A Few Helpful Ingredient Notes

Chicken: Rotisserie chicken makes this recipe ridiculously easy. Leftover grilled chicken also works beautifully.

Rice: White rice, brown rice, jasmine rice, or even leftover takeout rice can all work here. Just make sure it’s cooked beforehand.

Broccoli: Fresh broccoli gives the best texture, but frozen broccoli is a lifesaver on busy nights. Just thaw and drain it first so the casserole doesn’t get watery.

Cheese: Sharp cheddar adds the most flavor, but feel free to mix in mozzarella, Monterey Jack, or Colby cheese for extra gooeyness.

How to Make Creamy Chicken Broccoli Rice Cheese Casserole

Step 1: Prep the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish so cleanup stays easy later.

Step 2: Mix the Main Ingredients

In a large mixing bowl, combine the cooked chicken, broccoli florets, and cooked rice.

This is already starting to look like comfort food heaven.

Step 3: Make the Creamy Sauce

In another bowl, whisk together:

Cream of chicken soup
Milk
Sour cream
Garlic powder
Onion powder
Salt
Pepper

The sauce should look smooth and creamy. If it seems thick, don’t panic—it loosens up beautifully while baking.

Step 4: Combine Everything

Pour the creamy mixture over the chicken, broccoli, and rice.

Add 1½ cups of shredded cheddar cheese and stir gently until everything is evenly coated. Every bite should get a little cheesy goodness.

Step 5: Assemble the Casserole

Spread the mixture evenly into the prepared casserole dish.

Top with the remaining cheese because casseroles follow one important life rule: there’s no such thing as too much cheese.

Step 6: Bake Until Bubbly

Bake for 25–30 minutes until the casserole is hot and bubbling around the edges.

If using crispy fried onions, sprinkle them on top during the last 5 minutes of baking.

That crunchy topping absolutely takes this dish over the top.

Step 7: Let It Rest

Allow the casserole to cool for about 5–10 minutes before serving.

Yes, waiting is hard. But molten cheese burns are real, friends.

Make It Ahead

Use What You Have

One of my favorite stories from this recipe came from someone doing an “eat what you have” pantry challenge. They used canned chicken and were shocked by how delicious it turned out.

That’s the beauty of casseroles—they’re flexible, forgiving, and still comforting even when the fridge looks a little sad.

Fun Variations to Try

Make It Extra Creamy

Swap the sour cream for:

Greek yogurt
Cream cheese
Mayo
Crème fraîche

Each one gives the casserole a slightly different personality, but all taste delicious.

Add More Veggies

This recipe handles extra vegetables beautifully:

Mushrooms
Spinach
Peas
Cauliflower
Carrots

A little extra color never hurts.

Turn Up the Cheese

If you’re feeding serious cheese lovers, mix multiple cheeses together. Sharp cheddar plus mozzarella creates the dreamiest cheese pull.

And honestly? Extra cheese is rarely a bad idea.
