Directions:

Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking dish with olive oil.

Brown the ground beef and onion in a skillet, then season with salt, pepper, garlic powder, and paprika. Layer half in the baking dish.

Add a layer of potato slices and half the cheese. Repeat with the remaining beef, potatoes, and another layer of cheese.

Mix condensed soup and milk; pour over the casserole.

Cover with foil and bake for 1 hour. Uncover, add the remaining cheese, and bake until bubbly and the potatoes are tender.

Let it stand for 10 minutes before serving. Garnish with parsley.
