A comforting casserole featuring shredded hash browns, a creamy sauce, and a crispy onion topping, perfect for any gathering. This dish is rich, savory, and incredibly satisfying.
For an extra crispy topping, crush some cornflakes or potato chips and mix them with the melted butter before spreading over the potatoes. This recipe can be assembled ahead of time and refrigerated. Bake an additional 10-15 minutes if baking from cold.
