This Creamy Chicken Broccoli Rice Cheese Casserole is the perfect mix of tender chicken, fresh broccoli, soft rice, and gooey melted cheese all baked together in a creamy sauce. It’s a comforting dish that feels like a warm hug on a plate. The broccoli adds a nice pop of green and a little crunch, while the chicken keeps it hearty and filling.
I love making this casserole on busy weeknights because it’s pretty simple to put together, and it always turns out tasty and satisfying. One little tip I have is to use fresh broccoli and cook it just until it’s bright green and tender, so it doesn’t get mushy during baking. Also, a good sharp cheddar cheese makes such a difference—I like to grab whatever I have on hand, but sharp cheddar brings the best flavor for me.
When serving, I like to scoop it up straight from the casserole dish and pair it with a simple side salad or some crusty bread if I want to keep things easy. It’s one of those meals that makes everyone at the table smile and ask for seconds. Honestly, this casserole feels like a classic family dinner you’ll want to come back to again and again.
Key Ingredients & Substitutions
Chicken: Cooked chicken breast works great here. Rotisserie chicken is a super convenient swap and already seasoned!
Broccoli: Fresh is best for a nice texture. You can use frozen broccoli too—just thaw and drain well to avoid sogginess.
Rice: White rice is classic, but brown rice adds nuttiness and fiber. Just cook it fully before adding.
Cheese: Sharp cheddar gives that bold cheesy flavor. If you want milder, try Monterey Jack or Colby. Mozzarella adds gooey stretchiness but can be left out.
Cream of Chicken Soup: Use canned for ease, or make a simple homemade cream sauce with butter, flour, and chicken broth for a fresher taste.
How Do I Keep Broccoli Crisp and Not Mushy?
To keep broccoli bright and slightly crisp:
- Steam or blanch the broccoli just until tender but still firm—2 to 3 minutes is enough.
- Immediately rinse with cold water or plunge into ice water to stop cooking.
- Drain thoroughly before mixing to avoid excess moisture that makes casserole soggy.
This way your broccoli stays a nice contrast to the creamy, cheesy rice and chicken.
Equipment You’ll Need
- 9×13-inch casserole dish – I like this size because it holds everything perfectly and bakes evenly.
- Large skillet – great for sautéing onions and garlic easily without making a mess.
- Mixing bowls – for combining all the ingredients before baking, keeping everything tidy.
- Measuring cups and spoons – for accurate ingredient portions.
- Foil or a microwave-safe cover – to keep the casserole moist while baking.
- Knife and cutting board – for chopping onions, garlic, and cooked chicken.
Flavor Variations & Add-Ins
- Swap chicken for cooked shrimp or turkey for different proteins that keep it hearty and flavorful.
- Add a sprinkle of crumbled bacon or cooked_ham_ for extra richness and smoky flavor.
- Mix in cooked mushrooms or roasted bell peppers to boost veggies and add new textures.
- Use pepper jack or gouda cheese instead of cheddar for a spicy or smoky twist.

Creamy Sauce & Cheese:

- 2 cups shredded sharp cheddar cheese, divided

Seasoning & Extras:

How Much Time Will You Need?
This casserole takes about 15 minutes to prepare, and approximately 35-40 minutes for baking. Plus, allow 5 minutes to rest before serving. Total time around 55-60 minutes.
Step-by-Step Instructions:
1. Prepare Your Oven and Veggies:
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish. If you haven’t already, steam or blanch your broccoli until bright green and just tender. Set aside.
2. Sauté The Onions and Garlic:
In a large skillet, heat olive oil or butter over medium heat. Add finely chopped onion and sauté until soft and translucent, about 3-4 minutes. Add minced garlic and cook for another 30 seconds until fragrant. Remove from heat.
3. Mix All The Ingredients:
In a large mixing bowl, combine the cooked chicken, cooked rice, steamed broccoli, and sautéed onion and garlic. Stir in sour cream, cream of chicken soup, mayonnaise (if using), dried thyme, salt, and pepper. Mix everything gently until well combined.
4. Add the Cheeses:
Fold in 1½ cups of shredded cheddar cheese and the mozzarella cheese if you’re using it. This creates a creamy, cheesy mixture that’s just right.
5. Bake the Casserole:
Spread the mixture evenly in your prepared casserole dish. Sprinkle the remaining ½ cup cheddar cheese and Parmesan cheese evenly over the top. Cover the dish with aluminum foil to keep in moisture and bake for 25 minutes.
6. Finish Baking & Serve:
After 25 minutes, remove the foil and bake uncovered for another 10-15 minutes until the cheese on top is melted and golden brown. Take the casserole out of the oven and let it rest for 5 minutes—it helps everything set nicely.
7. Garnish and Enjoy!
Sprinkle chopped fresh parsley on top for a fresh, pretty touch. Serve warm and enjoy your hearty, creamy, cheesy casserole with family and friends!
Can I Use Frozen Broccoli for This Casserole?
Yes, you can use frozen broccoli. Just thaw it completely and drain any excess water before adding to the casserole to prevent it from getting watery.
How Do I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through, adding a splash of milk if it seems dry.
Can I Make This Ahead of Time?
Absolutely! Prepare the casserole up to the baking step, cover it with foil, and refrigerate overnight. When ready, bake as directed, adding a few extra minutes if baking from cold.
What Can I Substitute for Cream of Chicken Soup?
You can make a simple homemade cream sauce with butter, flour, and chicken broth for a fresher, less processed option. This gives great creamy texture without the canned soup.
