A comforting and flavorful casserole combining creamy chicken, hash browns, and cheese, perfect for a cozy dinner.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even cooking.
In a large mixing bowl, combine the sour cream, half-and-half, diced onion, chopped green chilies, salt, and pepper.
Mix until the ingredients are well incorporated for a smooth base.
Add the shredded hash browns, cooked chicken, and 2 cups of cheddar cheese to the bowl. Stir until evenly combined.
Ensure the hash browns and chicken are evenly coated with the creamy mixture.
Transfer the mixture into a greased 13x9-inch baking dish, spreading it out evenly.
Use a spatula to smooth the top for even baking.
Bake the casserole uncovered in the preheated oven for 1 hour and 15 minutes, or until golden and bubbly.
Check the casserole halfway through to ensure even cooking.
Sprinkle the remaining 0.5 cup of cheddar cheese over the top and bake for an additional 5 minutes, until melted.
For a golden crust, broil for the last 2 minutes.
Let the casserole cool for 5 minutes before serving. Enjoy your delicious meal!
Allowing the casserole to rest helps it set for easier serving.
