Creamy Chicken Broccoli Rice Cheese Casserole is everything you want in a cozy homemade meal. It’s loaded with tender chicken, soft rice, fresh broccoli, and lots of melted cheese — all baked together in a creamy, flavorful sauce. Each bite is warm, comforting, and full of familiar flavors that make you feel instantly at home.
This recipe is perfect for busy weeknights or weekend gatherings because it’s easy to make ahead and always a hit with family and friends. The creamy base ties everything together beautifully, while the cheese adds just the right touch of indulgence. Plus, using rice gives it that hearty texture that makes the dish satisfying without being too heavy.
I love serving this casserole straight from the oven with a green salad or some buttery dinner rolls. It’s a complete meal on its own but also reheats beautifully — making it ideal for leftovers or meal prep. Once you try it, you’ll see why it’s one of my go-to comfort dinners!
Key Ingredients & Substitutions
Here’s what makes this casserole creamy, flavorful, and perfectly balanced — along with some easy swaps if needed:
Chicken: Shredded or diced cooked chicken breast works perfectly. Rotisserie chicken is a great shortcut, and leftover roast chicken or turkey is also excellent.
Broccoli: Fresh broccoli florets add color and texture. If you’re using frozen broccoli, just thaw and drain it well before mixing to avoid excess moisture.
Rice: Use cooked white rice for best texture. Brown rice, jasmine rice, or even cauliflower rice can work if you prefer a lighter or gluten-free version.
Cheese: Sharp cheddar gives that classic cheesy flavor. For extra creaminess, mix in mozzarella or Colby Jack for a milder taste.
Cream of Chicken Soup: This binds everything together and adds richness. You can use homemade cream sauce made with butter, milk, and flour for a fresher flavor.
Sour Cream: Adds tang and creaminess. Greek yogurt can replace it for a lighter version without losing texture.

Flavor Variations & Add-Ins

- Smoky touch: Mix in crumbled bacon or pancetta before baking for crunch.
- Spicy version: Stir in a teaspoon of hot sauce or a sprinkle of paprika for subtle heat.

How Much Time Will You Need?
This casserole takes about 15 minutes to prep and 25–30 minutes to bake, for a total of roughly 45 minutes. It’s an easy dinner you can make ahead or bake fresh any night of the week.
Step-by-Step Instructions:
1. Preheat and Prepare the Base
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish. In a skillet, melt the butter over medium heat, then add the chopped onion and garlic. Sauté for 3–4 minutes until fragrant and soft. Set aside.
2. Combine Chicken, Rice, and Broccoli
In a large mixing bowl, combine the cooked rice, shredded chicken, and broccoli florets. Stir in the sautéed onion and garlic mixture to distribute flavors evenly.
3. Prepare the Creamy Sauce
In a separate bowl, whisk together the cream of chicken soup, milk, and sour cream until smooth. Pour this mixture over the rice and chicken blend. Season with salt and pepper, and stir until everything is well coated.
4. Assemble and Bake
Transfer the mixture into the prepared baking dish, spreading it evenly. Sprinkle the shredded cheddar cheese over the top. Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbly around the edges.
5. Garnish and Serve
Remove from the oven and let cool slightly before serving. Sprinkle with chopped parsley for a fresh, colorful finish. Serve warm alongside salad or dinner rolls for a comforting meal everyone will love.
Pro Tips for Best Texture & Taste
These small details make the difference between a good casserole and a truly amazing one:
- Use pre-cooked rice: It won’t absorb too much liquid and keeps the dish creamy, not dry.
- Don’t overbake: Bake just until bubbly and hot; overbaking can make it dry.
- Mix well: Combine all ingredients thoroughly so the sauce coats everything evenly.
- Add milk if needed: If it looks dry before baking, stir in a splash of milk to bring back creaminess.
- Let it rest: Allow the casserole to sit for 5 minutes after baking to help it set before serving.
