Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking.

Step 2: Mix the Ingredients

In a large mixing bowl, combine the shredded chicken, thawed hashbrowns, cream of chicken soup, sour cream, shredded cheddar cheese, garlic powder, onion powder, paprika, salt, black pepper, melted butter, and milk. Stir until well combined.

Step 3: Assemble the Casserole

Spread the mixture evenly into the greased baking dish, pressing it down slightly to ensure an even layer.

Step 4: Add the Topping

Sprinkle the crushed Ritz crackers (or cornflakes) evenly over the top of the casserole. This adds a delicious crunchy texture.

Step 5: Bake

Place the casserole in the preheated oven and bake for 40-45 minutes or until golden brown and bubbling.

Step 6: Garnish and Serve

Once baked, remove from the oven and let it cool for a few minutes. Sprinkle chopped parsley on top for added flavor and color. Serve warm and enjoy!
