Ingredients

For this perfect Broccoli Cheddar Chicken and Rice Casserole, you’ll need:

• 2 lbs (900g) boneless, skinless chicken breasts, cut into 1-inch pieces
• 2 cups (400g) uncooked long-grain white rice, rinsed and drained
• 4 cups (950ml) low-sodium chicken broth
• 1 medium onion, finely diced (about 1 cup)
• 3 cloves garlic, minced
• 4 cups (340g) fresh broccoli florets, cut into bite-sized pieces
• 3 cups (340g) sharp cheddar cheese, freshly grated and divided
• 1 cup (240ml) heavy cream
• 2 tablespoons (30g) unsalted butter
• 2 teaspoons Italian seasoning
• 1 teaspoon paprika
• 1/2 teaspoon garlic powder
• Salt and freshly ground black pepper to taste

Pro Tips

Perfect Rice Texture: For the best rice consistency in your Broccoli Cheddar Chicken and Rice Casserole, rinse the rice thoroughly under cold water until the water runs clear. This removes excess starch and prevents your casserole from becoming gummy. Also, resist the urge to peek during baking—keeping the foil tightly sealed allows the rice to steam properly.

Cheese Selection Matters: While pre-shredded cheese is convenient, it contains anti-caking agents that prevent it from melting smoothly. Take the extra few minutes to grate your own cheddar—you’ll be rewarded with a creamier, more uniform cheese sauce. For extra flavor depth, replace 1 cup of the cheddar with Gruyère or Monterey Jack.

Broccoli Preparation: To prevent soggy broccoli, don’t add it at the beginning of the baking process. Instead, partially cook the casserole, then add the broccoli florets during the last 20 minutes of baking. This technique ensures perfectly tender-crisp broccoli that maintains its bright green color and nutritional value while still absorbing the savory flavors of the casserole.

Instructions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with cooking spray or butter. This prevents sticking and makes cleanup easier when serving your Broccoli Cheddar Chicken and Rice Casserole.

Step 2

Season the chicken pieces generously with salt, pepper, and half of the Italian seasoning. In a large skillet over medium-high heat, melt the butter and brown the chicken for about 4-5 minutes. You’re not trying to cook it through completely—just developing flavor with a light golden exterior. Transfer the chicken to a plate and set aside.

Step 3

In the same skillet, add the diced onion and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. The fond (browned bits) from the chicken adds tremendous flavor to your aromatics.

Step 4

Transfer the onion and garlic mixture to your prepared baking dish. Add the rinsed rice, chicken broth, heavy cream, remaining Italian seasoning, paprika, and garlic powder. Stir until well combined. Carefully place the partially cooked chicken pieces evenly throughout the mixture.

Step 5

Cover the baking dish tightly with aluminum foil and bake for 30 minutes. This initial covered baking period allows the rice to absorb liquid and begin cooking properly.

Step 6

After 30 minutes, remove the dish from the oven and carefully uncover (watch for steam). Stir the mixture gently, then fold in the broccoli florets and 2 cups of the grated cheddar cheese. The residual heat will begin to soften the broccoli without making it mushy.

Step 7

Return the dish to the oven, uncovered, and bake for an additional 20-25 minutes until the rice is tender and most of the liquid has been absorbed. For the perfect finishing touch, sprinkle the remaining cup of cheddar cheese on top and bake for 5 more minutes until melted and slightly golden. Let your Broccoli Cheddar Chicken and Rice Casserole rest for 10 minutes before serving to allow the flavors to settle and the sauce to thicken slightly.

Variations

Vegetarian Broccoli Cheddar Rice Casserole: Skip the chicken and double the broccoli for a satisfying meatless version. Add 1 cup of sliced mushrooms sautéed with the onions for an umami boost, and consider mixing in 1/2 cup of red bell peppers for extra color and vitamins. Use vegetable broth instead of chicken broth to keep it completely vegetarian.

Spicy Southwest Chicken Broccoli Casserole: Transform this Broccoli Cheddar Chicken and Rice Casserole with southwestern flavors by adding 1 diced jalapeño, 1 cup of corn kernels, and 1 can of black beans (drained and rinsed). Replace the Italian seasoning with 2 teaspoons of taco seasoning, and swap half the cheddar for pepper jack cheese. Top with crushed tortilla chips during the final 5 minutes of baking for a crunchy finish.

Make-Ahead Freezer Version: Prepare the casserole up through Step 4, but use parboiled rice instead of regular for better freezing results. Cool completely, wrap tightly, and freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator, add the broccoli and cheese, and bake as directed, adding an extra 10-15 minutes to the cooking time.

Storage and Serving

Your Broccoli Cheddar Chicken and Rice Casserole will keep beautifully in the refrigerator for up to 4 days when stored in an airtight container. For longer storage, portion the cooled casserole into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating in a 350°F oven until warmed through (about 20 minutes), adding a splash of chicken broth if it seems dry.

For an impressive presentation, serve this casserole straight from the baking dish alongside a crisp green salad dressed with a simple vinaigrette to cut through the richness. For a complete comfort food experience, pair with warm, crusty garlic bread perfect for soaking up the creamy sauce. When reheating individual portions, a sprinkle of fresh cheddar on top before microwaving creates a freshly melted cheese experience that makes leftovers feel special.

FAQs

Can I use brown rice instead of white rice?
Yes, but brown rice requires more liquid and longer cooking time. Increase the chicken broth to 5 cups and plan for an additional 20-25 minutes of covered baking time. Check frequently toward the end to ensure it doesn’t dry out.

Can I use frozen broccoli instead of fresh?
Absolutely! Use the same quantity of frozen broccoli florets, but don’t thaw them first. Add them directly to the casserole in Step 6, and they’ll cook perfectly during the remaining bake time.

My casserole seems too liquidy. What went wrong?
Different rice varieties absorb liquid differently. If your casserole seems too wet after the recommended baking time, remove the foil and bake for an additional 5-10 minutes to allow excess moisture to evaporate.

Can I make this ahead of time?
Yes! Assemble the casserole up to the point of baking, cover, and refrigerate for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the covered baking time since you’re starting with cold ingredients.

Is there a dairy-free alternative?
Replace the heavy cream with full-fat coconut milk and use dairy-free cheese alternatives formulated for melting. The flavor profile will change slightly, but you’ll still get a creamy, satisfying result.

This Broccoli Cheddar Chicken and Rice Casserole is comfort food at its finest — creamy, cheesy, and packed with protein and vegetables in every bite.
