The Full Hash Brown Casserole Recipe
Ingredients
- 30 ounces frozen shredded hash browns, thawed
- ½ cup diced yellow onion
- 10.5 ounces can cream of chicken soup
- 1 ½ cups sour cream (regular or light)
- ½ cup butter, melted and divided
- ½ teaspoon salt
- ½ teaspoon freshly ground black pepper (or to taste)
- 2 ½ cups shredded sharp cheddar cheese
- 2 cups corn flakes, crushed
Instructions
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Lightly coat a 13 x 9-inch baking dish with nonstick cooking spray to prevent sticking.
- Mix the Ingredients: In a large mixing bowl, combine the thawed hash browns, diced onion, cream of chicken soup, sour cream, ¼ cup of the melted butter, salt, pepper, and shredded cheddar cheese. Stir everything together until well mixed. Tip: Ensure the hash browns are fully thawed for even cooking.
- Transfer to Baking Dish: Pour the hash brown mixture into the prepared baking dish, spreading it out evenly for even cooking.
- Prepare the Topping: In a separate bowl, mix the crushed corn flakes with the remaining ¼ cup of melted butter until the flakes are well coated. Sprinkle this mixture evenly over the top of the hash brown mixture.
- Bake: Place the baking dish in the preheated oven and bake for 50 to 55 minutes. You’ll know it’s ready when the casserole is golden brown and bubbly. Tip: Keep an eye on the casserole during the last 10 minutes to prevent over-browning.
- Serve: Once baked, let the casserole cool slightly before serving. Enjoy the cheesy goodness of your hash brown casserole!
