There’s something magical about the slow cooker – it allows bold flavors to develop while you go about your day. And in Texas, we love big, hearty meals that satisfy the soul, especially when they combine rich, comforting ingredients. This Slow Cooker French Onion Meatloaf with Swiss does just that, infusing the classic comfort food with the deep, savory flavor of French onion soup, all topped with gooey Swiss cheese.
