Slow Cooker French Dip Sandwiches are a perfect balance of savory, melty, and comforting flavors. Juicy, tender beef is slow-cooked in a rich broth, piled onto toasted hoagie rolls, topped with melty cheese, and served with a warm, flavorful au jus for dipping. This easy set-it-and-forget-it meal is ideal for busy weeknights, game nights, or when you need some serious comfort food.
