Creating Broccoli, Rice, Cheese, and Chicken Casserole is a simple process if you follow these easy steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) so it’s ready for the casserole.
2. Prepare Your Dish: Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
3. Mix Ingredients: In a large bowl, combine the cubed chicken, cooked rice, broccoli, 1 cup of cheddar cheese, cream of chicken soup, milk, garlic powder, onion powder, salt, and pepper. Stir until everything is evenly coated.
4. Transfer to Baking Dish: Pour the mixture into the prepared baking dish and spread it evenly.
5. Add Toppings: Sprinkle the remaining ½ cup of cheddar cheese over the top for a delicious cheesy layer. If using, add breadcrumbs for an extra crunch.
6. Bake: Place in the preheated oven and bake for 30-35 minutes, or until the cheese is bubbly and lightly golden.
7. Cool Slightly: Once done, remove from the oven and let it cool for about 5 minutes before serving.
8. Serve: Grab yourself a spoonful and enjoy!

By following these steps, you’ll create a scrumptious Broccoli, Rice, Cheese, and Chicken Casserole that everyone will love.
