Ingredients:

2 cups cooked chicken, shredded or diced
1 (30 oz) package frozen hashbrowns, thawed
2 cups shredded cheddar cheese
1/2 cup sour cream

1/2 cup mayonnaise
1 (10.75 oz) can condensed cream of chicken soup
1/2 cup diced onion
1/2 cup diced bell pepper (red or green)
1/4 cup butter, melted
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon dried thyme (optional)
Salt and pepper to taste
1 cup crushed cornflakes or breadcrumbs (optional, for topping)
2 tablespoons melted butter (optional, for topping)

Instructions:

Preheat the Oven: Preheat your oven to 350°F (175°C).
Prepare the Hashbrowns: If your hashbrowns are frozen, thaw them according to the package instructions. You can speed up the process by microwaving them for a few minutes. Once thawed, press them between paper towels to remove excess moisture.
Combine Ingredients: In a large mixing bowl, combine the thawed hashbrowns, shredded chicken, shredded cheddar cheese, diced onion, and diced bell pepper.
Prepare the Sauce: In a separate bowl, mix together the sour cream, mayonnaise, condensed cream of chicken soup, melted butter, garlic powder, onion powder, dried thyme (if using), salt, and pepper. Stir until well combined.

Combine the Mixture: Pour the sauce mixture over the hashbrown and chicken mixture. Stir everything together until well combined.
Transfer to Casserole Dish: Grease a 9×13-inch casserole dish. Transfer the hashbrown and chicken mixture into the dish and spread it out evenly.
Optional Topping: If you want a crispy topping, combine the crushed cornflakes or breadcrumbs with the 2 tablespoons of melted butter in a small bowl. Sprinkle this mixture evenly over the casserole.
Bake: Place the casserole dish in the preheated oven and bake for about 45-55 minutes, or until the casserole is hot and bubbly, and the top is golden brown.
Serve: Remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with fresh herbs like parsley, if desired.
Enjoy: Serve your Chicken Hashbrown Casserole hot and enjoy your delicious meal!
