Whether you know it as potatoes au gratin or scalloped potatoes, this bubbling casserole of creamy sliced potatoes and cheese will warm up any cold night. Start the cooking process on the stove by getting the sauce and potatoes warmed through. Then layer the potatoes, sauce, and cheese in the dish and bake until golden brown. Serve alongside glazed ham or steak for a rich and comforting meal.
Special equipment: If you have a mandoline, this is the ideal moment to pull it out so you get uniformly thin potato slices.
Game plan: This recipe can be completely made ahead. Cool to room temperature, cover with plastic wrap or aluminum foil, and refrigerate for up to 2 days. Rewarm uncovered in a 350°F oven for about 30 to 40 minutes.
