Preheat oven to 350 Fahrenheit/ 175 Celsius.

Clean, peel, and thinly slice potatoes. (Use a mandolin if available)

Place sliced potatoes, milk, salt, and pepper in a pot. Simmer until tender. (Roughly 10-12 minutes)

Butter a casserole dish. (Hotel pan if available)

Place roughly half of the potatoes neatly in the dish. Sprinkle with half the cheese. Then layer with remaining potatoes, and top with the remaining cheese.

Cover with foil. Bake for 45 minutes. Remove foil and return to oven to allow cheese to brown, if so desired.

Allow to cool 10 minutes.
