~1 hr 30 min · 4 steps · 4 servings

  1. Step 1 · Prepare the Gratin Dish

    Preheat the oven to 375°F (190°C). Rub the bottom and sides of a 12 by 9-inch (33 by 23-cm) gratin dish that is about 1 1/2 inches (4 cm) deep, or a similar baking dish, with the smashed garlic. Butter the bottom and sides of the dish and set aside.

  2. Step 2 · Layer the Potatoes and Cheese

    Using a mandoline or sharp knife, slice the potatoes into paper-thin rounds. Starting with the largest slices, arrange about one-quarter of the potatoes in overlapping layers in the gratin dish, completely covering the bottom. Season with salt, pepper, and nutmeg. Scatter about one-quarter of the cheese over the potatoes. Continue layering until the dish is full, finishing with grated cheese.

  3. Step 3 · Add Cream and Butter

    Place the gratin dish on a sheet pan to catch any drips. Drizzle with the heavy cream and scatter the butter over the top.

  4. Step 4 · Bake the Gratin

    Bake until the potatoes are tender when poked with a paring knife and the top is golden brown and bubbling, 55 minutes to 1 hour. Serve immediately.
