Preheat oven to 350 degrees.

Brown your ground beef and set aside

Peel and slice potatoes and set aside. We use this easy mandoline slicer to cut our potatoes quickly.

In a mixing bowl, combine cream of mushroom soup, milk, salt and pepper to taste. Mix well. Set aside.

Spray a 9x13 baking dish with non stick spray.

Layer in the pan, potatoes, beef, soup, and cheese. Then repeat. Top with remaining cheese.

Remover foil and bake another 30 minutes until potatoes are fork tender.

Allow it to sit for 10 minutes, then cut and serve.
