Ingredients

For this crowd-pleasing Cheesy Broccoli Chicken and Rice Casserole, you’ll need:

• 2 cups white rice, uncooked (or 4 cups cooked rice)
• 2 lbs boneless, skinless chicken breasts, cut into 1-inch pieces
• 4 cups fresh broccoli florets (about 2 medium heads)
• 2 cups sharp cheddar cheese, freshly grated (plus ½ cup for topping)
• 1 medium yellow onion, finely diced
• 3 cloves garlic, minced
• 2 cups chicken broth (low sodium preferred)
• 1 cup heavy cream
• 4 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 teaspoon dried thyme
• 1 teaspoon garlic powder
• ½ teaspoon paprika
• Salt and freshly ground black pepper to taste
• 2 tablespoons olive oil

The quality of cheese makes a significant difference in this broccoli chicken casserole recipe—using freshly grated cheddar rather than pre-shredded varieties ensures a smoother, more flavorful sauce without anti-caking additives.

Pro Tips

Chicken Preparation: For the juiciest chicken in your Cheesy Broccoli Chicken and Rice Casserole, avoid overcooking it during the initial sauté. Cook the chicken pieces just until they lose their pink color on the outside but aren’t fully cooked through. They’ll finish cooking perfectly in the oven without becoming dry or rubbery. Season the chicken generously before cooking to build layers of flavor from the very beginning.

Broccoli Technique: Blanch your broccoli florets for just 2 minutes in boiling salted water, then immediately plunge them into ice water. This quick process preserves the bright green color, stops the cooking process, and ensures your broccoli maintains a slight crunch even after baking. Properly blanched broccoli prevents your casserole from becoming mushy or developing that overcooked, sulfurous smell.

Rice Perfection: For the ideal texture in your chicken and rice casserole, slightly undercook your rice if preparing it in advance. Aim for an al dente texture, as it will absorb moisture from the sauce during baking. Alternatively, use leftover rice from the day before—the slightly dried-out texture is actually perfect for casseroles as it helps maintain distinct grains rather than turning mushy.

Instructions

Step 1: Prepare the Base Ingredients
Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. If you’re starting with uncooked rice, prepare it according to package instructions, but reduce the cooking time by about 2 minutes to keep it slightly al dente. Meanwhile, season your chicken pieces generously with salt, pepper, and garlic powder. In a large skillet over medium-high heat, warm the olive oil until shimmering, then add the chicken pieces in a single layer without overcrowding. Cook for 3-4 minutes until just golden on the outside but not fully cooked through. Remove to a plate and set aside.

Step 2: Create the Flavor Base
In the same skillet, reduce heat to medium and add the butter. Once melted, add the diced onions and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. Sprinkle the flour over the mixture and stir constantly for about 1 minute to cook out the raw flour taste. This roux will help thicken your sauce to creamy perfection.

Step 3: Build the Sauce
Gradually whisk in the chicken broth, stirring constantly to prevent lumps from forming. Once fully incorporated, pour in the heavy cream and continue stirring. Add the dried thyme and paprika, then bring the mixture to a gentle simmer. Cook for 3-5 minutes until the sauce begins to thicken. Remove from heat and stir in 2 cups of the shredded cheddar cheese until completely melted and smooth. Taste and adjust seasonings as needed.

Step 4: Assemble the Casserole
In a large mixing bowl, combine the cooked rice, blanched broccoli florets, and partially cooked chicken pieces. Pour the cheese sauce over the mixture and fold gently until everything is evenly coated. Transfer this mixture to your prepared baking dish, spreading it out in an even layer. Sprinkle the remaining ½ cup of shredded cheddar over the top for that irresistible golden crust.

Step 5: Bake to Perfection
Cover the baking dish with aluminum foil and bake for 25 minutes. Then remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown on top. Allow your Cheesy Broccoli Chicken and Rice Casserole to rest for 5-10 minutes before serving to let the flavors meld and the sauce set up slightly.

Variations

Vegetarian Broccoli Rice Casserole: Transform this dish by omitting the chicken and doubling the broccoli for a hearty vegetarian main. Add 1 cup of sliced mushrooms sautéed with the onions and increase the cheese to 3 cups total for extra richness. You can also mix in 1 cup of cooked lentils or chickpeas for additional protein, creating a satisfying meatless alternative that maintains all the creamy comfort of the original.

Southwest Chicken Broccoli Rice Bake: Give your Cheesy Broccoli Chicken and Rice Casserole a Tex-Mex twist by adding 1 diced red bell pepper, 1 cup of corn kernels, and 1 can of drained black beans. Season with 1 tablespoon of chili powder, 1 teaspoon of cumin, and ½ teaspoon of cayenne pepper (adjust to taste). Replace half the cheddar with pepper jack cheese and top with crushed tortilla chips during the final 10 minutes of baking for added crunch.

Gluten-Free Option: This casserole adapts beautifully to dietary restrictions. Simply substitute the all-purpose flour with cornstarch (1 tablespoon) or a gluten-free flour blend. Double-check that your chicken broth is gluten-free, and serve with full confidence to those with gluten sensitivities.

Storage and Serving

Your Cheesy Broccoli Chicken and Rice Casserole can be refrigerated in an airtight container for up to 4 days. For best results when reheating, add a splash of milk or chicken broth to restore moisture, cover with foil, and warm in a 325°F oven for 15-20 minutes until heated through. For longer storage, freeze individual portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating.

Serve this comforting casserole alongside a crisp green salad dressed with a light vinaigrette to balance the richness. For a complete meal presentation, pair with garlic bread or buttered dinner rolls to soak up every last bit of the creamy sauce. For a more elegant serving option, portion the casserole into individual ramekins before the final baking stage and top each with extra cheese for personalized presentation perfect for dinner parties.

For a refreshing contrast, offer a side of cranberry sauce or quick-pickled vegetables that cut through the richness with their acidity and brightness.

FAQs

Can I use frozen broccoli instead of fresh?
Yes, frozen broccoli works well in this Cheesy Broccoli Chicken and Rice Casserole. There’s no need to blanch it—simply thaw completely, pat dry with paper towels to remove excess moisture, and add directly to the casserole mixture.

Can I use pre-cooked rotisserie chicken to save time?
Absolutely! Using rotisserie chicken is a great time-saver. Simply shred or dice about 3 cups of cooked chicken and add it directly to the mixture without the initial sautéing step.

Why is my casserole coming out watery?
This typically happens if the broccoli wasn’t dried properly after blanching or if the sauce wasn’t thickened enough. Ensure your roux is cooked until it’s a light golden color before adding liquids, and always let blanched vegetables drain thoroughly.

Can I prepare this casserole ahead of time?
Yes, you can assemble the entire casserole up to 24 hours in advance and refrigerate it covered. When ready to bake, allow it to sit at room temperature for 30 minutes, then add 10-15 minutes to the covered baking time.

What’s the best cheese to use if I don’t have cheddar?
Gruyère offers an excellent depth of flavor, while Monterey Jack provides a wonderful melt. A combination of mozzarella and Parmesan also works beautifully in this chicken broccoli rice bake.
