CLASSIC SCALLOPED POTATOES RECIPES

Steps:

• Position a rack in the upper third of the oven and preheat to 425 degrees F. Generously brush a large skillet with butter, then rub with the garlic. Heat the skillet over medium-high heat. Add half of the potatoes, sprinkle with 3/4 teaspoon salt, and pepper to taste, then arrange the remaining potatoes on top. Sprinkle with 3/4 teaspoon salt, and pepper to taste. Pour the broth and milk over the potatoes, then add the nutmeg and bay leaves; simmer 3 minutes. 
• Generously brush a shallow baking dish with butter and slide the potatoes into the dish; arrange with a fork, if desired. (If your skillet is ovenproof, you can skip this step and bake the potatoes right in the skillet.) 
• Dot the potatoes with the cut-up butter and sprinkle with the gruyere. Bake until golden, about 25 minutes. Let rest 5 minutes before serving. Discard the bay leaves.

Steps:

• Preheat oven to 400°. In a skillet, cook the onion and 2 tablespoons of the butter over moderately low heat, stirring, until it is very soft. In a heavy saucepan, melt 6 tablespoons of the remaining butter over moderately low heat, whisk in the flour, and cook the roux, whisking, for 3 minutes. Add the milk, scalded, in a stream, whisking, and bring the sauce to a boil. Simmer the sauce, whisking, for 1 minute and add salt and pepper to taste.
• Peel the potatoes and slice them ⅛-inch thick. Spread about one third of the sauce in the bottom of a well-buttered 3-quart gratin dish at least 2 ½-inches deep, cover it with a layer of potato slices, overlapping the slices slightly, and cover the potatoes with one third of the onions. Sprinkle the onions with one third of the Cheddar and continue to layer the remaining sauce, potatoes, onions, and Cheddar in the same manner. Sprinkle the top with bread crumbs, and dot it with the remaining 1 tablespoon butter, cut into bits.
• Bake the mixture, covered with foil, in the middle of preheated oven for 20 minutes. Remove the foil and bake the potato mixture for 35 minutes more, or until the top is golden and the potatoes are tender.
