Creamy Chicken Broccoli Rice Cheese Casserole is a comforting, hearty dish that brings together tender chicken, fresh broccoli, fluffy rice, and gooey melted cheese all baked into one warm, delicious casserole. The creamy sauce coats everything perfectly, making each bite rich and satisfying without being too heavy.
I love how this casserole is easy to customize—you can add your favorite cheese or swap out the veggies if you want. It’s one of those meals I turn to when I want something simple to prepare but that still feels like a special, home-cooked dinner. Plus, having everything baked together means minimal cleanup, which I always appreciate!
My favorite way to enjoy this casserole is right out of the oven with a crisp green salad on the side. It’s a family favorite that always gets compliments, and leftovers taste just as good the next day for lunch. This dish really feels like a warm hug after a long day.
Key Ingredients & Substitutions
Chicken: Cooked chicken adds protein and flavor. Rotisserie chicken works great for convenience. If you prefer, use cooked turkey or tofu for a vegetarian twist.
Broccoli: Fresh broccoli gives a nice crunch and color. Frozen broccoli can be used in a pinch—just thaw and drain it well to avoid extra moisture.
Rice: I like jasmine or long-grain rice for texture. You can substitute with brown rice for more fiber, but add extra liquid and bake a little longer.
Cheese: Sharp cheddar melts beautifully here, but feel free to mix in mozzarella or Monterey Jack for a milder taste. For dairy-free, try a vegan cheese alternative.
Sour Cream & Cream Soup: These make the casserole creamy. Greek yogurt can replace sour cream for a tangier flavor. Use cream of chicken or mushroom soup, or try a homemade white sauce for a fresher taste.
How Do You Get the Perfect Creamy, Well-Baked Casserole?
The secret is balancing moisture and baking time:
- Cook rice and chicken ahead so they don’t add too much liquid while baking.
- Steam broccoli just until tender-crisp to keep texture and color.
- Sauté onions and garlic to bring out their flavor before mixing.
- Mix all ingredients well for an even creaminess.
- Spread the mixture evenly in the dish for uniform baking.
- Bake uncovered to let the top get golden and bubbly—don’t cover, or it might turn soggy.
- Let the casserole rest 5 minutes after baking so it sets nicely and is easier to serve.
Equipment You’ll Need
- 9×13 inch baking dish – perfect size for even baking without overflowing.
- Large skillet – for sautéing onions and garlic to boost flavor.
- Mixing bowl – to combine all ingredients easily and evenly.
- Wooden spoon or silicone spatula – gentle tools to mix without mashing the rice.
- Measuring cups and spoons – to keep ingredient amounts consistent and simple.
Flavor Variations & Add-Ins
- Swap chicken for cooked sausage or turkey for a different protein twist.
- Use mozzarella or pepper jack cheese instead of cheddar for a mild or spicy flavor.
- Add chopped bell peppers or mushrooms for extra veggies and texture.
- Stir in a teaspoon of smoked paprika or cayenne for a subtle smoky or spicy kick.

Time You’ll Need
This casserole takes about 15 minutes to prepare, including cooking the onions and mixing ingredients. Baking will take around 30-35 minutes, plus a 5-minute resting time before serving. Overall, expect about 50 minutes from start to finish.
Step-by-Step Instructions:
1. Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray to prevent sticking.
2. Cook the Aromatics
In a large skillet, heat the olive oil or butter over medium heat. Add the finely chopped onion and sauté for 3-4 minutes until softened. Add the minced garlic and cook for another 30 seconds until fragrant. Remove from heat.
3. Mix the Casserole Ingredients
In a large mixing bowl, combine the cooked chicken, cooked rice, steamed broccoli, sautéed onion and garlic, sour cream, cream of mushroom soup, milk, 1 cup of shredded cheddar cheese, dried thyme or poultry seasoning, and salt and pepper to taste. Stir everything together until the mixture is creamy and well mixed.
4. Assemble and Bake
Transfer the mixture into your prepared baking dish, spreading it out evenly. Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top.
Bake uncovered for 30-35 minutes, until the casserole is bubbly and the cheese on top is melted and slightly golden.
5. Rest and Serve
Remove the casserole from the oven and let it sit for about 5 minutes to set. Garnish with freshly chopped parsley or chives if you like before serving.

Can I Use Frozen Broccoli Instead of Fresh?
Yes, you can use frozen broccoli—just thaw it completely and drain any excess water before mixing it into the casserole to prevent sogginess.
Can I Make This Casserole Ahead of Time?
Absolutely! Prepare the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes if needed.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for 3-4 days. Reheat in the microwave or oven until warmed through, adding a splash of milk if the casserole seems dry.
Can I Substitute the Rice?
Yes! Brown rice works well but may require additional cooking liquid and longer baking time. Quinoa or cauliflower rice are also good alternatives for different textures and flavors.
