A delicious and comforting cheesy hash brown casserole, perfect for brunch or as a side dish.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking and a perfect texture.
In a large mixing bowl, combine the sour cream, melted butter, salt, and pepper.
Ensure the butter is slightly cooled to prevent curdling the sour cream.
Add the frozen hash brown potatoes, diced onion, and shredded cheddar cheese to the bowl. Mix until well combined.
Mix gently to avoid breaking the potatoes too much.
Transfer the mixture into a greased 9x13 baking dish and spread it out evenly.
Greasing the dish prevents sticking and makes cleanup easier.
Sprinkle the crushed potato chips evenly over the top.
Press the topping lightly to help it adhere to the mixture.
Bake in the preheated oven for 1 hour, or until the top is golden and the casserole is bubbling.
Check halfway through baking and rotate the dish for even cooking.
Let the casserole cool for 5 minutes before serving. Enjoy!
Cooling slightly allows the casserole to set for easier serving.
