Ingredients

Scale

Main Ingredients:

  • 1 (30 ounces) frozen shredded hash browns, thawed
  • 2 cups shredded cheddar cheese
  • 1 pint sour cream
  • 1 (10.75 ounces) condensed cream of chicken soup

Supporting Ingredients:

  • ½ cup butter
  • ½ cup chopped onion
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Topping Ingredients:

  • 2 cups corn flakes, crushed
  • ¼ cup butter, melted

Instructions

  1. Thaw the entire 30-ounce package of frozen hash browns completely. Pat them dry with paper towels to remove excess moisture.
  2. Pour ½ cup melted butter into a spacious mixing bowl. Whisk until smooth and slightly cooled.
  3. Add the full can of cream of chicken soup, 1 pint sour cream, and ½ cup chopped onion to the butter. Blend ingredients until uniformly combined.
  4. Incorporate 1 ½ cups shredded cheddar cheese, ½ teaspoon salt, and ¼ teaspoon black pepper. Fold gently to distribute seasonings evenly.
  5. Thoroughly grease a 9×13 inch baking dish with cooking spray or butter.
  6. Transfer the hash brown mixture into the prepared dish. Spread the mixture smoothly and evenly with a spatula.
  7. Cover the dish tightly with plastic wrap and refrigerate overnight or for at least 8 hours.
  8. Crush 2 cups of corn flakes inside a sealed plastic bag using a rolling pin. Crush until they become fine, consistent crumbs.
  9. Melt ¼ cup butter in a small microwave-safe bowl for 20-30 seconds.
  10. Pour melted butter over crushed corn flakes. Stir until corn flakes are completely coated.
  11. Remove the casserole from the refrigerator 30 minutes before baking to reduce temperature shock.
  12. Preheat your oven to 350F (175C). Position the rack in the center of the oven.
  13. Sprinkle the remaining ½ cup cheddar cheese across the top of the casserole.
  14. Distribute the buttered corn flake crumbs uniformly over the cheese layer.
  15. Bake for 45-55 minutes at 350F until the top becomes golden brown and the internal temperature reaches 165F (74C).
  16. Allow the casserole to rest for 5-10 minutes before serving. This helps the dish set and makes cutting easier.

Notes

  • Thaw hash browns completely to prevent excess moisture that can make the casserole soggy.
  • Grate fresh cheese instead of using pre-shredded for better melting and richer flavor.
  • For a gluten-free version, swap corn flakes with crushed gluten-free crackers or potato chips.
  • Make this vegetarian by replacing cream of chicken soup with cream of mushroom or celery soup.
