Ingredients You’ll Need

11 tablespoons unsalted butter: This is used for sautéing and creating a rich base for the sauce. If you’re in a pinch, you could substitute with margarine.
1 small onion, chopped: Adds savory depth that complements the chicken beautifully. Yellow or white onions work best here.
1½ lbs. boneless skinless chicken breast, cut into bite-sized pieces: The star of the dish! Chicken thighs can also be used for a juicier bite.
3 cloves garlic, minced: Garlic brings aromatic warmth to the dish. Freshly minced is always best for its strong flavor.
2 cups water: This is added to cook the rice; feel free to substitute with low-sodium chicken broth for extra flavor.
½ teaspoon salt: Enhances all the flavors in the dish. Adjust this depending on your taste preference.
1 cup uncooked long grain white rice: This fluffy rice soaks up the delicious flavors. Brown rice can be used, but cooking times will vary.
4 cups broccoli florets, cut into bite-sized pieces: Adds a nutritious boost and vibrant color. Frozen broccoli works if fresh isn’t available; just thaw and drain.
4 tablespoons all-purpose flour: Thickens the cheese sauce, creating a creamy texture. If gluten-free, cornstarch can be a substitute.
¼ teaspoon red pepper flakes: Adds a hint of heat. Omit if you prefer a milder dish.
½ teaspoon onion powder: Enhances the onion flavor in the casserole.
½ teaspoon dried marjoram: Adds an earthy depth that pairs wonderfully with chicken.
½ teaspoon dried thyme leaves: This herb provides a subtle, aromatic flavor.
1¼ cups low sodium chicken broth: Used to create the sauce’s base; feel free to use regular chicken broth if you prefer.
2 cups milk: Creates a creamy texture for the sauce; whole milk will yield the richest flavor.
2 cups shredded sharp cheddar cheese: Adds creaminess and a delightful cheesy taste. A mix of cheeses like mozzarella or Monterey Jack could also work.
1 sleeve Ritz crackers, crushed (about 32 crackers): Creates a crunchy topping that’s simply irresistible.

How to Make Chicken Broccoli Rice Casserole

Sauté the Onion and Chicken: Melt 2 tablespoons of unsalted butter in a large skillet over medium heat. Add the chopped onion and cook for about 2 minutes until it becomes translucent. Move the onions to one side, then add in the chicken pieces. Cook until the chicken is nicely browned on each side, about 6-8 minutes total. Remove the cooked chicken and set aside, continuing to stir the onions.
Cook the Garlic: Once all chicken is removed, add the minced garlic to the skillet and cook for 1 minute until fragrant.
Prepare the Rice and Broccoli: Meanwhile, in a saucepan, add 2 cups of water, 1 tablespoon of butter, salt, and the long-grain rice. Heat until boiling, cover, and simmer for about 12-15 minutes or until all water is absorbed. While that simmers, steam the broccoli florets until tender.
Preheat the Oven: At this point, preheat your oven to 375°F (190°C) and spray a 9×13-inch casserole dish with nonstick cooking spray to prevent sticking.
Make the Cheese Sauce: In a separate pot, melt 4 tablespoons of butter over medium-low heat. Whisk in the flour, allowing it to cook for 2-3 minutes until golden and slightly bubbling. Incorporate the red pepper flakes, onion powder, marjoram, and thyme. Slowly whisk in the low-sodium chicken broth and milk, alternating between the two. Continue whisking until the sauce is smooth and begins to thicken, usually around 4-5 minutes on low heat. Gradually add in 1¼ cups of cheddar cheese until melted and creamy.
Combine Ingredients: Stir in the cooked chicken, rice, and broccoli into the cheese sauce until well coated.
Layer in Casserole Dish: Spoon half of the chicken mixture into the casserole dish and sprinkle with ½ cup of cheddar cheese. Layer the remaining mixture on top and finish with the remaining cheese.
Add Cracker Topping and Bake: Mix the crushed Ritz crackers with 4 tablespoons of melted butter, then sprinkle over the top. Bake for about 20-25 minutes or until the casserole is bubbly and golden brown on top.

Storing & Reheating

To store any leftovers at room temperature, you can keep it out for about 2 hours. Refrigerate the casserole in an airtight container for up to 4 days. It can also be frozen for up to 3 months—just make sure it’s in a well-sealed container. For reheating, pop it in the oven at 350°F (175°C) for about 20 minutes until warm throughout. Note that the creamy texture may become slightly thicker, but stirring in a splash of milk can refresh it wonderfully.

Chef’s Helpful Tips

Overcrowding the skillet while browning chicken can lead to steam instead of a nice sear; work in batches for best results.
Ensure that your flour is cooked through to avoid a raw taste, don’t rush this step.
If you prefer a more pronounced flavor, consider adding fresh herbs like parsley or cilantro before serving.
Feel free to mix in other veggies like peas or bell peppers for added color and nutrients.
Baking times may vary; watch for golden edges and a bubbly center for perfect cooking.
