Classic Potato Gratin

Preheat oven to 350 degrees. Butter a 9-inch square baking dish, and set aside.

Whisk together cream, 1 teaspoon salt, 1/4 teaspoon pepper, and the nutmeg in a small bowl, and set aside. Toss potatoes, 1 teaspoon salt, and 1/4 teaspoon pepper in a large bowl.

Arrange one-third of potatoes in buttered dish, overlapping slices. Sprinkle with one-third of the cheese. Repeat two more times with remaining potatoes and cheese (end with a cheese layer). Pour reserved cream mixture over top layer. Gently shake dish back and forth to distribute evenly.

Cover with foil; bake 30 minutes. Remove foil; bake until bubbling and well browned, about 30 minutes more. Let cool slightly before serving.
