Preheat oven to 350 degrees. In a 9-to-10-inch pie plate or six 10-ounce ramekins, mound stuffing on the bottom; layer with cranberry sauce, turkey, and carrots. Drizzle with gravy; spread potatoes over the surface to sides of dish. Top with more cranberry sauce, if desired.
Place pie or ramekins on a baking sheet, and bake until heated through and potatoes are golden, 35 to 40 minutes. If using ramekins, reduce cooking time to 20 to 30 minutes. Let cool slightly.
