Ingredients

Casserole Base:

  • 20 oz frozen hashbrowns (shredded or diced)
  • 2 cups shredded cheddar cheese
  • 1 tsp salt
  • 1 tsp pepper
  • 2 cups sour cream
  • 10.5 oz can cream of chicken soup (or homemade)
  • ½ cup milk
  • 1 lb shredded cooked chicken

Topping:

  • 2 cups crushed cornflakes
  • 4 tbsp melted butter

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.

Step 2: Prepare the Casserole Mixture

  1. In a large mixing bowl, whisk together sour cream, cream of chicken soup, milk, salt, and pepper until well combined.
  2. Add in the shredded cooked chicken, shredded cheddar cheese, and frozen hashbrowns. Stir until everything is evenly coated with the creamy mixture.

Step 3: Assemble the Casserole

  1. Pour the hashbrown and chicken mixture into the prepared baking dish, spreading it out evenly.

Step 4: Make the Crunchy Topping

  1. In a separate bowl, mix the crushed cornflakes with the melted butter, ensuring the flakes are evenly coated.
  2. Sprinkle this mixture over the casserole in an even layer, covering the top completely for a delicious crunch.

Step 5: Bake the Casserole

  1. Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the casserole is bubbling and the topping is golden brown.
  2. Remove from the oven and let it rest for 5-10 minutes before serving.

Serving Suggestions

  • Garnish with chopped fresh parsley or green onions for a pop of color and flavor.
  • Serve alongside a crisp green salad or steamed vegetables for a balanced meal.
  • Pair with garlic bread or dinner rolls to soak up all the creamy goodness.

Tips for the Best Cheesy Chicken Hashbrown Casserole

✅ Use Rotisserie Chicken: Save time by using pre-cooked rotisserie chicken for added flavor.
✅ Homemade Cream of Chicken Soup: If you prefer homemade over canned, make a quick version with chicken broth, butter, flour, and milk.
✅ Crunchy Topping Options: Instead of cornflakes, try using crushed Ritz crackers or panko breadcrumbs.
✅ Extra Cheese: Add Parmesan or mozzarella for an even cheesier, gooey texture.


Storage and Reheating

To Store:
