This Creamy Chicken Broccoli Rice Cheese Casserole is one of those all-in-one meals that combines comfort and convenience in a single dish. It’s filled with tender chicken, steamed broccoli, chewy rice, and plenty of melted cheese, all brought together by a rich, creamy sauce that makes every bite feel like a warm hug. The cheese naturally creates a golden crust on top that’s just irresistible.
I love making this casserole when I want something hearty but easy to put together. It’s a great way to use up leftover chicken or even cook the chicken right in the dish while everything bakes. The broccoli adds a nice pop of color and freshness, so it doesn’t feel heavy or boring. I always find that mixing the rice into the sauce keeps it nice and creamy without drying out, which can happen in other casseroles.
When I serve this, I like to pair it with a simple side salad or some garlic bread, but honestly, it’s pretty perfect all on its own. It’s the kind of meal that feels homey and familiar, the kind that everyone at the table reaches for seconds. Whether it’s a busy weeknight or a casual weekend dinner, this creamy chicken broccoli rice cheese casserole never fails to hit the spot for me and my family.
Key Ingredients & Substitutions
Chicken: Using cooked diced chicken breast keeps the texture tender. You can swap for rotisserie chicken to save time or even shredded chicken thighs for richer flavor.
Rice: White rice is classic here, but brown rice works well for a nuttier taste and added fiber. Just be sure it’s fully cooked before mixing.
Broccoli: Steamed or blanched broccoli keeps its bright color and slight crunch. Frozen broccoli can work too; just thaw and drain well.
Cheese: Sharp cheddar gives great flavor and melts beautifully. Feel free to mix in mozzarella for stretchiness or Monterey Jack for milder taste.
Sour Cream & Mayonnaise: These create the creamy base. If you want a lighter option, Greek yogurt works as a tasty substitute.
Cream of Chicken Soup: This adds richness and depth. You can use homemade cream sauce or soup alternatives like cream of mushroom if preferred.
How Do You Get the Perfect Creamy Texture Without It Being Too Runny?
The secret to a creamy but firm casserole lies in balancing the wet ingredients and cooking time.
- Mix the sour cream, mayonnaise, and cream of chicken soup well until smooth to create a thick sauce.
- Make sure rice is fully cooked beforehand so it doesn’t soak up excessive moisture during baking.
- Don’t over-steam broccoli; slightly firm florets hold up better in the dish.
- Bake uncovered so moisture can evaporate, which helps the casserole set.
- Let the dish rest a few minutes after baking; it firms up and becomes easier to serve.
Equipment You’ll Need
- 9×13 inch baking dish – perfect size for even cooking and easy serving.
- Large mixing bowl – to combine all ingredients smoothly without spills.
- Measuring cups and spoons – for accurate ingredient amounts and flavor balance.
- Wooden spoon or silicone spatula – great for stirring without scratching your bowl.
- Steamer basket or microwave-safe bowl – to quickly steam broccoli before mixing.
Flavor Variations & Add-Ins
- Swap chicken for cooked turkey or ham to change up the protein while keeping it hearty.
- Mix in cooked mushrooms or diced bell peppers for extra veggies and texture.
- Try adding a pinch of smoked paprika or a dash of cayenne for a subtle spicy kick.
- Use pepper jack cheese instead of cheddar for a creamy dish with a little heat.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and mix all the ingredients, plus 30-35 minutes to bake until bubbly and golden on top. Allow an additional 5 minutes to let the casserole set before serving.
Step-by-Step Instructions:
1. Prepare the Baking Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish using cooking spray or butter to prevent sticking.
2. Combine the Main Ingredients:
In a large bowl, mix the cooked diced chicken, cooked rice, and steamed broccoli until well combined.
3. Mix the Creamy Sauce:
In a separate bowl, stir together the sour cream, cream of chicken soup, mayonnaise, garlic powder, onion powder, salt, and pepper until the mixture is smooth and creamy.
4. Combine Sauce and Main Ingredients:
Pour the creamy sauce over the chicken, rice, and broccoli mixture. Stir everything together so all the ingredients are evenly coated.
5. Add Cheese and Transfer to Dish:
Fold 1 cup of shredded cheddar cheese into the mixture. Then, transfer everything evenly into the prepared baking dish.
6. Top and Bake:
Sprinkle the remaining ½ cup cheddar cheese evenly over the top. If you like, add the grated Parmesan cheese for extra flavor and a crispy crust. Bake uncovered for 30-35 minutes until the casserole bubbles and the cheese melts into a golden brown.
7. Rest and Serve:
Remove from the oven and let the casserole sit for 5 minutes before serving. This helps it set and makes it easier to serve. Enjoy your warm, creamy, and cheesy casserole!
Can I Use Frozen Broccoli for This Casserole?
Yes! Just make sure to thaw and drain the frozen broccoli well before adding it to avoid extra moisture that could make the casserole watery.
Can I Prepare This Casserole Ahead of Time?
Absolutely! You can assemble the casserole a day in advance, cover it tightly, and refrigerate. When ready, bake it for an extra 5-10 minutes to ensure it’s heated through.
How Should I Store Leftovers?
Store leftover casserole in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave, adding a splash of milk if it seems dry.
Can I Substitute Brown Rice Instead of White Rice?
Yes, brown rice works great for a nuttier flavor and added fiber. Just be sure it’s fully cooked before mixing since it takes longer to cook than white rice.
