Instructions

Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish or spray with non-stick cooking spray.

Step 2: Mix the Filling
In a large bowl, combine:

Shredded chicken
Thawed hashbrowns
Sour cream
Cream of chicken soup
Shredded cheddar cheese
Milk
Garlic powder, onion powder, salt, and pepper

Stir everything together until fully combined and creamy.

Step 3: Assemble the Casserole
Pour the mixture into the prepared baking dish.
Spread it out evenly with a spatula.

Step 4: Add the Topping
In a small bowl, mix crushed cornflakes or breadcrumbs with melted butter.
Sprinkle evenly over the top of the casserole.
(Optional) Add an extra layer of shredded cheese on top for a golden cheesy crust.

Step 5: Bake to Perfection
Cover the dish with foil and bake for 30 minutes.
Remove foil and bake for another 15–20 minutes, or until the top is golden and bubbly.
Let the casserole rest for 5–10 minutes before serving.

Step 6: Garnish and Serve
Sprinkle with chopped parsley for a fresh finish (optional).
Serve warm with a simple side salad, steamed veggies, or as-is for a complete meal.

Notes

Use Pre-Cooked Chicken – Save time with rotisserie or leftover chicken.
Thaw Hashbrowns Completely – This helps with even cooking and texture.
Make It Extra Creamy – Add a bit more sour cream or a splash of milk if you like a saucier casserole.
Crispy Topping Tip – Bake uncovered for the last 15–20 minutes to get that perfect crunch.
Customize It – Add cooked broccoli, mushrooms, or diced bell peppers for extra veggies.
