Method
Preparation
- Preheat the oven to 350°F (175°C).
- Brown the ground beef over medium heat. If using, add the diced onion and cook until softened. Drain excess fat.
- In a large bowl, mix together the cream of mushroom soup, milk, salt, pepper, and garlic powder.
Layering
- In a greased 9x13 inch baking dish, layer half of the sliced potatoes, half of the cooked beef, and half of the cheese. Repeat the layers.
- Pour the soup mixture over the layered ingredients.
Baking
- Cover with foil and bake for 30 minutes.
- Remove the foil and bake for an additional 15-20 minutes until the potatoes are tender and the cheese is bubbly and golden.
Serving
- Allow to cool slightly before serving.
Notes
For best results, layer potatoes thicker than 1/4 inch. Store leftovers in an airtight container for up to 3 days, and you can freeze unbaked casserole for later use.
