Ingredients

Scale

Main Ingredients

  • 3 cups shredded cooked chicken
  • 1 cup sour cream
  • ½ cup mayonnaise
  • ½ cup milk
  • 1 ½ cups shredded cheddar cheese
  • ½ cup grated Parmesan cheese
  • 1 (30 ounces/850 grams) bag frozen hashbrowns, thawed
  • 1 (10.5 ounces/298 grams) can cream of chicken soup
  • 1 small onion, finely chopped (optional)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper, to taste

Topping

  • 1 cup crushed cornflakes (or breadcrumbs)
  • 3 tablespoons melted butter

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Make Creamy Sauce: In a bowl, whisk together the cream of chicken soup, sour cream, mayonnaise, milk, garlic powder, onion powder, salt, and pepper until the mixture is smooth and well combined.
  3. Combine Main Ingredients: Gently fold in the shredded cooked chicken, thawed hashbrowns, shredded cheddar cheese, grated Parmesan cheese, and finely chopped onion (if using) into the creamy sauce, mixing thoroughly to incorporate all ingredients evenly.
  4. Transfer to Baking Dish: Pour the combined mixture into the prepared baking dish, spreading it out evenly to create a smooth layer.
  5. Prepare Topping: In a small bowl, combine the crushed cornflakes with melted butter, stirring to coat the flakes well, then sprinkle this mixture evenly over the top of the casserole.
  6. Bake: Place the casserole in the preheated oven and bake for 40-45 minutes, or until the casserole is bubbly around the edges and the topping has turned golden brown and crisp.
  7. Rest: Remove the casserole from the oven and let it rest for 5-10 minutes. This allows the flavors to meld and the casserole to firm up slightly for easier serving.
  8. Optional Garnish: For a fresh touch, sprinkle chopped fresh parsley over the casserole before serving.

Notes

  • Thaw the frozen hashbrowns completely beforehand to ensure even cooking and prevent excess moisture.
  • You can substitute crushed breadcrumbs for cornflakes if preferred for the topping.
  • The optional onion adds a mild crunch and flavor, but you can omit it if desired.
  • Make sure to rest the casserole before serving to help it set and enhance flavors.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven for best results.
