Instructions: Preheat the oven to 450 deg. Soak the potato slices in cold water for 5 minutes. Drain the slices and pat dry with paper towels.

Transfer the potatoes to 2 large, rimmed baking sheets and toss each batch with 1 tbsp of the olive oil. Arrange the slices on the sheets side by side without overlapping, and season with salt and pepper. Bake for 8 minutes, or until the potatoes begin to turn golden brown; as they brown, transfer the potato chips to a rack with a spatula.

Reduce the oven temperature to 350 deg. In a bowl, mix the shredded cheeses, then divide among individual gratin dishes. Bake the cheese for about 7 minutes, or until bubbling. Drizzle with truffle oil and serve at once with the potato chips.
