Preparation

  1. Place about a third of the potato slices in one layer over the base of a glass or ceramic dish (8 by 8 by 2 inches). Sprinkle a third of the grated cheese and half of the garlic over the potatoes. Cover with another layer of the potato slices, another third of the cheese and the remaining garlic. Top with the remaining potato slices. Reserve the remaining cheese.
  2. In a small bowl stir together the cream, nutmeg, salt and pepper. Pour mixture over the potatoes. Cover tightly with microwavable plastic wrap.
  3. Cook at 100 percent power in a 650-to-700-watt oven for 6 minutes.
  4. Preheat conventional broiler.
  5. Prick plastic to release steam, remove from oven and uncover. Sprinkle the reserved cheese over the potatoes. Place under the broiler for a few minutes, until browned.
  6. Remove from broiler and allow to stand for a few minutes before serving.
  • Cooking time includes 20 minutes to precook the potatoes and 9 minutes for the gratin, including 6 minutes in the microwave and the remaining time under the conventional broiler.
