This recipe guides you through making classic patty melts, featuring savory ground beef patties, deeply caramelized onions, and melted Swiss cheese, all grilled between slices of buttery rye bread until golden and crisp. It's a comforting and satisfying dish, perfect for a hearty lunch or dinner, highlighting simple ingredients transformed into a flavorful American classic.
Achieving perfectly caramelized onions is crucial; cook them slowly over medium-low heat for 20-25 minutes, stirring occasionally, until deeply golden and sweet. Rushing this step will result in undercooked, bitter onions. For the beef patties, avoid overmixing the ground beef to ensure a tender texture and season generously. When grilling the assembled melts, maintain a consistent medium heat to allow the bread to become golden and crisp, and the Swiss cheese to melt thoroughly without burning the butter or bread. Using high-quality rye bread and good butter will significantly enhance the final flavor and texture. For an extra layer of flavor, consider adding a thin spread of Dijon mustard or a savory sauce like Russian dressing inside the sandwich before grilling.
