Making Chicken Hashbrown Casserole is a straightforward process. Follow these steps for a delicious outcome:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Baking Dish: Grease a 9×13 inch baking dish with cooking spray or butter.
3. Mix Ingredients: In a large bowl, combine cooked chicken, thawed hashbrowns, cream of chicken soup, sour cream, half of the cheddar cheese, diced onion, diced bell pepper, garlic powder, paprika, salt, and pepper. Mix well until everything is evenly distributed.
4. Transfer to Baking Dish: Pour the mixture into the prepared baking dish and spread it out evenly.
5. Top with Cheese: Sprinkle the remaining cheddar cheese over the top of the casserole.
6. Breadcrumb Topping (Optional): If desired, mix breadcrumbs with melted butter and sprinkle over the cheese for added crunch.
7. Bake: Place the casserole in the preheated oven and bake for 45-50 minutes, or until bubbly and golden brown.
8. Cool Slightly: Once out of the oven, let the casserole cool for about 10 minutes before serving. This will help it set and make serving easier.
