This Creamy Chicken Broccoli Rice Cheese Casserole is a perfect weeknight dinner that feels like a big, warm hug. It’s packed with tender chicken, fresh broccoli, fluffy rice, and loads of melty cheese all mixed into a creamy sauce that’s just right. The cheesy top crisps up nicely in the oven, adding that satisfying texture that everyone loves.
I always find that this casserole is such a comforting go-to when I want something easy but satisfying. I like to use leftover chicken or rotisserie chicken to make it even quicker. Plus, sneaking in the broccoli makes it a little healthier without anyone noticing, which is a win in my book. It’s one of those dishes you can make ahead and just pop in the oven when you’re ready, saving time and fuss.
My favorite way to serve it is straight from the casserole dish with a simple side salad or some crusty bread to soak up the creamy sauce. It’s the kind of meal that makes everyone around the table happy and full, and the leftovers (if there are any!) taste just as good the next day. I always look forward to cozy nights when I can whip this up and know we’re in for a tasty, easy meal.

Key Ingredients & Substitutions
Chicken: Using cooked chicken breast is great for tenderness and mild flavor. Rotisserie chicken or leftover chicken works perfectly to save time. For a lighter option, try turkey breast instead.
Broccoli: Fresh broccoli gives a nice texture and bright color. You can substitute with frozen broccoli if fresh isn’t available, just thaw and drain it well before mixing in.
Cheese: Sharp cheddar adds a rich, tangy taste while mozzarella melts smoothly. Feel free to swap cheddar for Colby Jack or Monterey Jack if you want a milder flavor. Cheese blends are fun here!
Cream of Chicken Soup: This creates the creamy base. If you prefer homemade, mix chicken stock with a roux (flour and butter) and some cream or milk for a fresh taste.
Sour Cream: It adds creaminess and slight tang. If you want a lighter option, plain Greek yogurt works well without losing flavor.
How Can I Get the Best Texture and Flavor in This Casserole?
To keep the casserole creamy and not dry, start with well-cooked rice—not mushy or too firm. Use freshly steamed broccoli that’s tender but still has a bite.
- Mix the creamy sauce thoroughly with the chicken, rice, and broccoli to coat everything evenly.
- Adding cheese inside and on top helps lock in moisture and creates a nice golden crust.
- Bake uncovered so the top gets bubbly and slightly browned but watch it closely to avoid over-baking.
- Letting the casserole rest after baking lets the flavors meld and makes serving easier.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for even cooking and easy serving of this casserole.
- Large mixing bowl – helps you combine all ingredients smoothly without mess.
- Whisk – great for blending the creamy sauce ingredients until smooth.
- Steamer basket or microwave-safe bowl – handy for quickly cooking broccoli to just the right tenderness.
- Measuring cups and spoons – essential for accurate amounts of rice, cheese, and spices.
- Wooden or silicone spoon – easy to stir the mixture without scratching your bowl.
Flavor Variations & Add-Ins
- Swap chicken for cooked turkey or ham – adds a different protein twist that’s still hearty and tasty.
- Add sautéed mushrooms or diced bell peppers – boosts flavor and adds extra veggies.
- Mix in some cream cheese or grated Parmesan – for a richer, tangier cheese flavor.
- Season with smoked paprika or a pinch of cayenne – gives a subtle smoky or spicy kick when you want more boldness.

- 1 cup shredded sharp cheddar cheese (divided)
- ½ cup shredded mozzarella cheese
For The Creamy Sauce:
- 1 can (10.5 oz) condensed cream of chicken soup
- 1 cup sour cream
- ½ cup milk
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp dried thyme or Italian seasoning
- Salt and pepper to taste
Optional Garnish:

Time Needed
It takes about 10-15 minutes to prepare all the ingredients and mix everything together. Baking time is around 25-30 minutes, plus a 5-minute rest after baking before serving. Expect to spend about 40-50 minutes total from start to finish.
Step-by-Step Instructions:
1. Prepare Your Oven and Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Mix Main Ingredients:
In a large bowl, combine the cooked chicken, cooked rice, and steamed broccoli. Stir gently to mix.
3. Make the Creamy Sauce:
In a separate bowl, whisk together the cream of chicken soup, sour cream, milk, garlic powder, onion powder, dried thyme or Italian seasoning, salt, and pepper until smooth and well blended.
4. Combine and Add Cheese:
Pour the creamy sauce mixture over the chicken, rice, and broccoli. Stir gently until everything is evenly coated. Then fold in half of the shredded cheddar cheese and all the mozzarella cheese.
5. Assemble and Bake:
Transfer this mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining cheddar cheese over the top. Bake uncovered for 25-30 minutes until bubbly and the cheese on top is melted and slightly golden.
6. Rest and Serve:
Remove the casserole from the oven and let it rest for about 5 minutes. This helps it set and makes it easier to serve. Garnish with fresh parsley if you like, then enjoy warm!
