Ingredients

Units Scale

For the Casserole:

  • 3 cups shredded cooked chicken (rotisserie works great)
  • 1 (30 oz) bag frozen hashbrowns, thawed
  • 1 (10.5 oz) can cream of chicken soup
  • 1 cup sour cream
  • 1/2 cup mayonnaise
  • 1/2 cup milk
  • 1 1/2 cups shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1 small onion, finely chopped (optional)
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • Salt and pepper, to taste

For the Topping:

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

Instructions

  1. Preheat the Oven:
    • Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
  2. Mix the Casserole Base:
    • In a large bowl, combine the cream of chicken soup, sour cream, mayonnaise, milk, garlic powder, onion powder, salt, and pepper. Stir until smooth.
    • Add the shredded chicken, hashbrowns, cheddar cheese, Parmesan cheese, and onion (if using). Mix well until evenly combined.
  3. Assemble the Casserole:
    • Pour the mixture into the prepared baking dish and spread it out evenly.
  4. Prepare the Topping:
    • In a small bowl, mix the crushed cornflakes (or breadcrumbs) with the melted butter. Sprinkle the topping evenly over the casserole.
  5. Bake:
    • Bake in the preheated oven for 40–45 minutes, or until the casserole is bubbling and the topping is golden brown.
  6. Serve:
    • Let the casserole cool for 5–10 minutes before serving. Garnish with fresh parsley if desired.

Notes

  • For added flavor, mix in cooked, crumbled bacon or diced green chiles.
  • To make it lighter, use Greek yogurt instead of sour cream and reduced-fat cheese.
  • If you’re short on time, you can use pre-cooked shredded chicken or canned chicken.
