A comforting and cheesy hash brown casserole, perfect for gatherings or family dinners.
Preheat your oven to 350°F (175°C).
Always preheat your oven to ensure even cooking.
In a saucepan, melt a small portion of butter and sauté the chopped onion until it becomes translucent.
Cook the onion on medium heat to avoid burning.
In a mixing bowl, combine the hash browns, sour cream, shredded cheddar cheese, sautéed onion, and salt. Mix until well combined.
Ensure the hash browns are evenly coated with the mixture.
Transfer the mixture into a greased 9x13 inch baking pan, spreading it out evenly.
Grease the pan to prevent sticking.
In a small bowl, mix the crushed cornflakes with melted butter. Sprinkle this mixture evenly over the top of the casserole.
Ensure the topping is evenly distributed for a consistent crunch.
Bake the casserole in the preheated oven for 40-50 minutes, or until the top is golden and the mixture is bubbly.
Check the casserole at 40 minutes to avoid over-baking.
Let the casserole cool slightly before serving. Enjoy your cheesy hash brown casserole!
Allowing the casserole to rest helps it set and makes serving easier.
