16 oz. sour cream
2.5 cups cheddar cheese, shredded
1/3 teaspoon black pepper

Instructions

Preheat Oven: Set your oven to 350°F (175°C).
Prepare Onions: Heat olive oil in a small skillet over medium heat. Add the diced onions and sauté for about 5 minutes until softened. Set aside.
Prepare Hash Browns: Pat the thawed hash browns dry to remove excess moisture.
Mix Ingredients: Reserve 1 cup of cheddar cheese for the topping. In a large bowl, combine the hash browns, sautéed onions, melted butter, cream of chicken soup, sour cream, the remaining cheddar cheese, and black pepper. Mix until well combined.
Assemble Casserole: Grease a 9×13-inch casserole dish and transfer the mixture into it. Spread evenly and top with the reserved cheddar cheese.
Bake Covered: Cover the dish with foil and bake for 45 minutes.
Crisp the Top: Remove the foil, increase the oven temperature to 400°F (200°C), and bake for an additional 10-15 minutes, or until the cheese on top is golden and slightly crispy.
Let Rest: Remove from the oven and allow the casserole to rest for 10 minutes before serving.
