A creamy and cheesy potato casserole that's perfect for any occasion.
Preheat your oven to 350°F.
Always preheat your oven to ensure even cooking.
In a large mixing bowl, combine the frozen hash brown potatoes, melted butter, sour cream, shredded cheddar cheese, and diced onion.
Ensure the ingredients are evenly mixed for consistent flavor.
Transfer the mixture into a 9x13 baking dish and spread it out evenly.
Use a spatula to smooth the top for even baking.
Bake in the preheated oven for 1 hour.
Check the casserole halfway through to ensure it's cooking evenly.
Sprinkle the crushed potato chips over the top and bake for an additional 5 minutes.
The topping should be golden and crispy.
Remove from the oven, let cool slightly, and serve warm.
Letting the casserole cool slightly helps it set and makes serving easier.
