How to Make Hashbrown Casserole

Preheat the Oven: Begin by arranging a rack in the middle of your oven. Preheat it to 375°F, and while it heats, coat a 9×13-inch baking dish with 1 teaspoon of room temperature unsalted butter to ensure a fantastic golden finish.
Mix the Base: In a large bowl, combine 1 (10.25) can of cream of chicken or cream of cheddar soup, 16 ounces of sour cream, and 1 large egg. Whisk these ingredients until the mixture is smooth and creamy—about 1-2 minutes will do the trick!
Combine Ingredients: Add in 32 ounces of thawed hash browns, 1/2 grated yellow onion, and half of the grated cheddar cheese (approximately 1 cup) to the soup mixture. Stir gently until everything is nicely blended.
Pour and Spread: Transfer the hash brown mixture into the prepared baking dish. Use a spatula to smooth it out into an even layer, creating a nice base for your casserole.
Top with Cheese: Sprinkle the remaining 1 cup of grated cheddar cheese evenly over the top of the casserole. This will ensure a delightful, cheesy crust.
Bake: Place your casserole in the preheated oven and bake for about 45 minutes, or until the edges are crisp and the top is starting to turn a lovely golden brown.
Cool and Serve: Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. Just before serving, sprinkle 1/4 teaspoon of freshly ground black pepper on top, cut into squares, and enjoy it while it’s hot!

Optional: Pair with fresh herbs for a pop of color and extra flavor.
