Better bread means better stuffing, so use a mixture of artisanal breads such as pumpernickel, sourdough, and multi-grain varieties. The hearty, chewy texture and flavorful crust holds up to the stock. Toss dried fruits such as apricots, figs, or raisins in with the apples for an added touch of sweetness. Assemble this casserole up to a day ahead, and simply cover and chill. Let stand at room temperature 30 minutes and then bake as directed.
