Creating your Cheesy Chicken Broccoli Rice Casserole can be straightforward. Just follow these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).

2. Prepare the Rice: If you haven’t done so, cook the rice according to package instructions and set it aside.

3. Cook the Broccoli: If using fresh broccoli, steam or blanch it for about 3-5 minutes until tender. Drain and set aside.

4. Mix Ingredients: In a large bowl, combine the cooked rice, chopped chicken, cooked broccoli, cream of chicken soup, milk, garlic powder, onion powder, salt, and pepper. Stir until well combined.

5. Add Cheese: Fold in about ¾ cup of shredded cheddar cheese to the mixture, reserving some for the topping.

6. Transfer to Baking Dish: Spread the mixture evenly into a greased 9×13-inch baking dish.

7. Top with Cheese: Sprinkle the remaining cheddar cheese evenly over the casserole. If using breadcrumbs, mix them with some melted butter and sprinkle on top for added crunch.

8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly.

9. Cool Slightly: Once removed from the oven, let the casserole cool for about 5-10 minutes to firm up before serving.

10. Serve and Enjoy: Scoop out portions and enjoy the warm, cheesy goodness!

These simple steps will guide you through the process, making it easy to whip up this incredible casserole any night of the week.
