Chicken Broccoli Rice Cheese Casserole – Creamy, Cheesy & Comforting

Why You’ll Love This Chicken Broccoli Rice Cheese Casserole

This casserole is the very definition of comfort food: warm, creamy, cheesy, and incredibly satisfying. It has everything a comforting meal needs — tender chicken for heartiness, rice for warmth and texture, broccoli for freshness and color, and a generous amount of cheese to bring it all together. It’s the kind of recipe that instantly relaxes you the moment you take your first bite.

One of the biggest reasons people love this casserole is how easy and reliable it is. You don’t need special ingredients or complicated techniques. Everything comes together in one dish, making both cooking and cleanup incredibly simple. Whether you’re feeding a large family or preparing weekday dinners ahead of time, this recipe gives you a big, comforting meal with minimal effort.

It’s also a very “forgiving” dish — meaning you can adjust it endlessly to suit your taste, your schedule, and whatever ingredients you have at home. Use cooked or rotisserie chicken, fresh or frozen broccoli, white or brown rice, cheddar or mozzarella — everything works. And because it stores and reheats beautifully, it’s perfect for meal prep, leftovers, or sharing.

Ingredients & Best Tips

Chicken

Use cooked chicken breast, chicken thighs, or leftover rotisserie chicken. Thigh meat adds extra juiciness, while breast meat keeps the casserole light and lean. Cut into small, bite-sized pieces so the chicken blends smoothly into every scoop.

Broccoli

Fresh broccoli florets provide the best texture and color, but frozen broccoli works perfectly too. If using frozen, thaw and pat dry to avoid excess moisture. Cutting the broccoli into smaller pieces helps it cook evenly without becoming mushy.

Rice

Cooked white rice is the usual choice because it absorbs the sauce beautifully and keeps the texture soft and creamy. You can also use brown rice for a heartier, nuttier flavor. Make sure the rice is fully cooked before mixing into the casserole.

Cheese

Cheddar cheese gives this casserole its signature creamy richness. Sharp cheddar adds tanginess, mild cheddar gives subtle flavor, and a blend of cheeses offers a deeper melt. Mozzarella or Monterey Jack can be added for extra creaminess.

Sauce Base

Many versions of this casserole use a mixture of chicken broth, milk, cream, or condensed soups to create the creamy sauce. This liquid base is what binds everything together, so it should be well-seasoned and thick enough to coat the ingredients. Garlic powder, onion powder, salt, pepper, and paprika enhance the depth of flavor.

How to Make Chicken Broccoli Rice Cheese Casserole (Step-by-Step)

1. Prepare the Ingredients

Cook and shred or dice the chicken. Cook the rice and set it aside. Chop the broccoli into small florets. Prepping each component beforehand makes assembling the casserole quick and stress-free.

2. Make the Sauce

Combine chicken broth, milk or cream, melted butter, and seasonings in a saucepan. If you’re using condensed soup, mix it in with the liquid until smooth. Heat until everything is well combined and slightly thickened.

3. Combine Everything

In a large mixing bowl, combine the chicken, rice, broccoli, cheese, and the prepared sauce. Stir until all ingredients are evenly coated.

4. Transfer to a Baking Dish

Pour the mixture into a greased casserole dish. Smooth the top and sprinkle with extra cheese for a beautiful golden crust.

5. Bake

Bake until the casserole is hot, bubbly, and the cheese is melted and golden. This usually takes 20–30 minutes depending on your oven and the size of your baking dish.

6. Cool Slightly and Serve

Let the casserole rest for a few minutes before serving. This helps the layers settle so each portion scoops out neatly.

Variations You Can Try

One of the best things about this casserole is how customizable it is. Here are some delicious variations:

Creamier Version

Add cream cheese or sour cream to the sauce for extra richness.

Crunchy Topping

Top with crushed crackers, panko breadcrumbs, or crispy fried onions for added texture.

Spicy Version

Add chili flakes, cayenne pepper, or diced jalapeños.

More Veggies

Add mushrooms, spinach, carrots, peas, or zucchini.

Protein Upgrades

Swap chicken for turkey, rotisserie leftovers, or even ham.

Cheese Variations

Try Swiss, mozzarella, Colby Jack, or pepper jack.

Storage & Reheating

Refrigerator

Store leftovers in an airtight container for up to 4 days. The casserole reheats beautifully in the oven or microwave.

Freezer

This casserole freezes really well. Freeze before baking or after — either works. Wrap tightly in foil or place in an airtight container for up to 2 months.

Reheating

Warm in the oven at 350°F (175°C) until heated through. Add a splash of broth or milk if the casserole seems dry. Microwave reheating works too, but the oven gives the best texture.

What to Serve With This Casserole

This dish is a complete meal on its own, but the following pair beautifully with it:

• Fresh garden salad
• Roasted vegetables
• Garlic bread or dinner rolls
• Steamed green beans or carrots
• Simple cucumber and tomato salad

Because the casserole is rich and comforting, lighter sides help balance the meal.
