Preheat your oven to 350°F and grease a 13x9" Casserole Dish well.
Brown the ground meat in a skillet over medium-high heat.
Add a layer of potato slices on the bottom of the casserole dish and season.
Sprinkle some cheese over the top of the potatoes.
Sprinkle ⅓ of the ground meat, then repeat with another 2 layers.
Mix the soup and evaporated milk with a whisk then pour over the layered ingredients. Lift with a fork here and there to allow the mixture to fall in-between the layers.
Sprinkle with a little more cheese over the top.
Grease a piece of aluminum foil then cover the hamburger potato casserole.
Bake in the oven for 1 hour.
Remove the foil and bake a further 30 minutes.
Take out of the oven and allow to sit for 10-15 minutes before serving.
Notes
After pouring the soup mixture over the ingredients it should fall and work it's way between the layers. You can help it with a fork though. You could also mix it before-hand and spoon between the layers as you're building the casserole. Make it even more hamburger-like and dress with lettuce, pickles, tomatoes and onions (if your family likes that).
