Preheat oven to 350°F (175°C).

Brown ground beef in a skillet over medium heat; drain excess grease.

In a bowl, mix cream of mushroom soup and milk until smooth.

Layer half of the potatoes in a greased baking dish.

Add half the onions, half the beef, and season with garlic powder, paprika, salt, and pepper.

Pour half of the soup mixture over the layers.

Repeat layers with remaining potatoes, onions, beef, and soup mixture.

Cover with foil and bake for 1 hour, or until potatoes are tender.

Remove foil, sprinkle with cheddar cheese, and drizzle melted butter on top.

Bake uncovered for 10–15 more minutes until cheese is melted and bubbly.

Serve hot and enjoy this hearty comfort meal!
