What makes this casserole so popular is its simple ingredients and rich flavor. Frozen hashbrowns save time, cooked chicken adds protein, and a creamy cheese sauce ties everything together. As it bakes, the casserole becomes bubbly and golden on top while staying soft and creamy inside. Every bite is savory, cheesy, and deeply comforting.
Ingredients
-
3 cups cooked chicken, shredded or diced
-
1 (30 oz) bag frozen hashbrown potatoes, thawed
-
1 can (10.5 oz) cream of chicken soup
-
1 cup sour cream
-
2 cups shredded cheddar cheese (or cheddar-jack blend)
-
½ cup milk
-
¼ cup unsalted butter, melted
-
1 small onion, finely chopped
-
1 teaspoon salt
-
½ teaspoon black pepper
-
½ teaspoon garlic powder
-
½ teaspoon paprika
-
Optional topping: 1 cup crushed cornflakes or buttery crackers
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray. This helps prevent sticking and makes serving easier once the casserole is baked.
Step 2: Make the Creamy Base
In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, melted butter, salt, black pepper, garlic powder, and paprika. Stir until smooth and well blended. This creamy mixture is the heart of the casserole, giving it richness and moisture while keeping everything tender.
Step 3: Add Chicken and Hashbrowns
Add the cooked chicken, thawed hashbrowns, chopped onion, and 1½ cups of the shredded cheese to the bowl. Gently fold everything together until evenly coated with the creamy sauce. Make sure the hashbrowns are fully thawed to prevent excess moisture in the casserole.
Step 4: Assemble the Casserole
Transfer the mixture to the prepared baking dish and spread it out evenly. Sprinkle the remaining ½ cup of shredded cheese over the top. If using a crunchy topping, mix the crushed cornflakes or crackers with a tablespoon of melted butter and sprinkle evenly over the casserole for extra texture.
Step 5: Bake
Place the casserole in the preheated oven and bake uncovered for 40–45 minutes, or until hot and bubbly with a lightly golden top. If the topping starts browning too quickly, loosely cover with foil during the last 10 minutes.
Step 6: Rest and Serve
Remove the casserole from the oven and let it rest for 10 minutes before serving. This helps the layers set and makes slicing easier. Serve hot and enjoy the creamy, cheesy goodness.

Cheesy Chicken Hashbrown Casserole is filling on its own, but it also pairs beautifully with simple sides like:
