Cheesy Funeral Potatoes

Preheat your oven to 350°F (175°C).
In a large bowl, combine the thawed hash browns, melted butter, cream of chicken soup, sour cream, cheddar cheese, Parmesan cheese, chopped onion, garlic powder, onion powder, salt, and pepper. Mix until everything is evenly combined.
Assemble the Dish:

Transfer the potato mixture into a greased 9×13-inch baking dish. Spread it out evenly with a spatula to ensure it’s compact and uniform.
Make the Topping:

In a small bowl, mix the crushed cornflakes with the melted butter. Stir to coat the cornflakes evenly.
Sprinkle the cornflake mixture evenly over the top of the potato mixture.
Bake:

Bake in the preheated oven for 45-50 minutes or until the top is golden brown and the casserole is bubbling around the edges.
Serve:

Let the casserole rest for 5-10 minutes before serving. This will allow it to set up and make it easier to serve.
Serve warm as a comforting side dish with your favorite main course.
