Follow these simple steps to create your delicious Broccoli, Rice, Cheese, and Chicken Casserole:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Broccoli: If you’re using fresh broccoli, steam it for about 3-5 minutes until it’s tender but still crisp. If you prefer a slightly more flavorful option, consider sautéing it in olive oil with a pinch of salt and garlic powder.
3. Mix Ingredients: In a large bowl, combine the cooked rice, shredded chicken, steamed broccoli, cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper. Stir well until everything is evenly mixed.
4. Add Cheese: Fold in half of the shredded cheddar cheese into the mixture. This will give the casserole its creamy consistency.
5. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish. Spread it evenly.
6. Prepare Topping (Optional): If you like a crunchy topping, sprinkle the breadcrumbs over the top layer. You can also add the remaining cheddar cheese for extra flavor.
7. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and the casserole is bubbly.
8. Cool and Serve: Once cooked, remove it from the oven and let it cool for a few minutes before serving. This allows the flavors to meld beautifully.

These simple steps will guide you to create a delicious casserole that is sure to impress.
