Creamy Chicken Broccoli Rice Cheese Casserole is the kind of recipe that feels like a warm hug in a dish — cozy, creamy, and full of cheesy comfort. It brings together tender chicken, crisp broccoli, and fluffy rice in a creamy, savory sauce topped with melted cheese. It’s the perfect one-dish meal that everyone at the table will love.
This casserole is one of my favorite weeknight dinners because it’s simple, hearty, and great for leftovers. Everything bakes together in one dish, making cleanup a breeze. The combination of creamy textures and cheesy flavor makes it satisfying without being too heavy — a classic comfort food done right.
It’s also incredibly versatile! You can swap in other veggies like cauliflower or green beans, add extra cheese for a golden crust, or toss in leftover ham or turkey for variety. I usually serve it with a fresh salad or some crusty bread, but it’s hearty enough to stand on its own. However you make it, this casserole always brings smiles to the table.
Key Ingredients & Substitutions
Each ingredient plays a role in making this casserole creamy, flavorful, and comforting — here’s what you’ll need and how to customize it:
Chicken: Cooked chicken breast keeps it lean and mild. Rotisserie chicken or shredded turkey work great too when you need a shortcut.
Broccoli: Fresh or steamed broccoli adds color and crunch. You can replace it with cauliflower, peas, or green beans for a change.
Rice: Cooked white rice gives a soft, fluffy base. Brown rice or quinoa add extra fiber and nutrients but may need a touch more liquid.
Cream of Chicken Soup: The key to that smooth, creamy texture. Use a low-sodium version, or make your own if you prefer a fresher, dairy-free option.
Cheese: Cheddar adds rich flavor and perfect meltiness. Mix in mozzarella for stretchiness or Monterey Jack for a milder taste.
Sour Cream & Mayo: These make the sauce extra creamy. For a lighter version, use Greek yogurt instead of mayo.

How Much Time Will You Need?
This casserole takes about 15 minutes to prep and 30–35 minutes to bake. Add 5 minutes to rest before serving, and you’ll have dinner ready in under 50 minutes total.
Step-by-Step Instructions:
1. Preheat and Prepare the Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking and make cleanup easier.
2. Make the Creamy Sauce
In a large bowl, combine the cream of chicken soup, sour cream, mayonnaise (if using), shredded cheddar, Parmesan, onion, garlic, salt, pepper, and thyme or Italian seasoning. Stir until smooth and well mixed.
3. Add the Main Ingredients
Fold in the cooked chicken, rice, and broccoli until they’re evenly coated with the creamy sauce. Be gentle to keep the broccoli florets intact.
4. Assemble and Bake
Transfer the mixture to your prepared dish, spreading it evenly. Sprinkle the top with extra cheddar cheese for that irresistible golden crust. Bake uncovered for 30–35 minutes until the cheese is melted and the edges are bubbly.
5. Rest and Serve
Remove from the oven and let rest 5–10 minutes before serving. Garnish with chopped parsley and a touch of fresh black pepper for a pop of color and freshness. Serve warm and enjoy!
Pro Tips for a Perfectly Creamy Texture
- Use cooled rice: Slightly cooled, cooked rice absorbs sauce without becoming mushy.
- Don’t overcook broccoli: Keep it tender-crisp so it holds up during baking.
- Bake uncovered: This allows steam to escape and gives a golden top.
- Let it rest: A short rest after baking helps the casserole set and slice cleanly.
- Add milk if dry: If the mixture looks thick before baking, stir in a splash of milk for extra creaminess.
