Ingredients

Instructions

  1. Preheat to 350°. Generously butter 2 quart baking dish. Place pie dish on rimmed baking sheet. Combine cream and garlic in small saucepan and bring to simmer over low heat. Cover and remove from heat.
  2. Arrange ⅓ of potato rounds, slightly overlapping, in the prepared baking dish; sprinkle with ½ teaspoon thyme and season lightly with salt and pepper. Pour ½ cup garlic cream over. Repeat layering 2 more times with remaining potato, thyme, salt, pepper, and garlic cream. Pour remaining garlic cream over, then ¼ cup milk. Sprinkle cheese over the surface.
  3. Bake gratin until golden on top and potatoes are very tender when a sharp knife is inserted, 1 hour to 1 hour 10 minutes (cover with foil if the top starts browning too quickly). Let the potatoes rest 10 minutes before serving.
