A creamy and cheesy hash brown casserole that's perfect for family gatherings or holiday meals.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even cooking.
Spray a 9×13 inch baking dish with cooking spray.
Use a non-stick spray to make cleanup easier.
In a large mixing bowl, combine the shredded hash browns, sharp cheddar cheese, diced onion, sour cream, and cream of chicken soup.
Mix thoroughly to ensure all ingredients are evenly distributed.
Melt the butter in a microwave-safe bowl and pour it into the hash brown mixture. Stir well.
Melt the butter in short intervals to avoid splattering.
Transfer the mixture to the prepared baking dish, spreading it out evenly.
Smooth the top for even baking.
In a small bowl, mix the crushed cornflakes with melted butter, then sprinkle over the casserole.
The topping adds a delightful crunch to the dish.
Bake in the preheated oven for 45 minutes, or until the casserole is bubbly and the topping is golden brown.
Check halfway through to ensure the topping doesn't over-brown.
Let the casserole cool for a few minutes before serving.
Allowing it to cool slightly makes it easier to serve.
