  • 2 ¼ lb. medium-sized potatoes
  • 1 large garlic clove minced
  • 4 ounces cheddar cheese
  • Salt and ground black pepper
  • 1 ¼ cups whole milk
  • 1 ¼ cups heavy cream


  • Preheat the oven to 275°. Peel the potatoes and cut them into thin slices. A mandoline is recommended for slicing the potatoes.
  • Butter a shallow baking or au gratin dish and place one-third of the potatoes in an even layer in the bottom. Sprinkle with half the minced garlic, one-third of the grated cheese, and some salt and pepper. Repeat with another third of the potatoes, the rest of the garlic, one-third of the cheese, and more salt and pepper. Create one final layer of neatly arranged, overlapping slices on top.
  • Warm, but do not boil, the milk and cream together in a pan with a dash more salt and pepper. Pour the warmed milk and cream over the entire dish and sprinkle with the remaining cheese.
  • Bake for 1 ½ to 2 hours or until the potatoes are tender when pierced with the top of a knife. Cover loosely with foil if the top begins to brown too quickly during cooking.
