Slowly caramelized onions and nutty Swiss cheese are folded into naturally leavened sourdough for a rich, deeply savory loaf with just a touch of sweetness from the onions. As it bakes, the cheese melts into the crumb and caramelizes along the crust, creating irresistible little pockets of flavor. Cozy, rustic, and made for cool fall days—serve it alongside soup, use it for an incredible grilled cheese, or simply tear off a piece while it’s still fresh.
