Cheesy Chicken Hashbrown Casserole

Few dishes are as comforting as a bubbling casserole fresh from the oven. Cheesy Chicken Hashbrown Casserole brings together tender chicken, crispy-edged hashbrowns, creamy sauce, and plenty of melted cheese in one hearty dish. It is easy enough for a weeknight dinner but satisfying enough to serve when family or friends come over.

The beauty of this casserole is its simplicity. Frozen hashbrowns eliminate the need to peel or shred potatoes, while cooked chicken makes preparation quick. Everything is combined in one baking dish, topped with cheese, and baked until hot, creamy, and golden.

2 cups shredded cheddar cheese, divided

Step-by-Step Instructions

1. Prepare the Oven and Baking Dish

Start by preheating your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with cooking spray or a little butter. Greasing the dish helps prevent the creamy potato mixture from sticking and makes serving easier later.

2. Thaw the Hashbrowns

If your hashbrowns are frozen, allow them to thaw before mixing them into the casserole.

For the best texture, gently squeeze out excess moisture with clean paper towels or a kitchen towel. Removing extra water helps prevent the finished casserole from becoming watery.
