This Southern-style patty melt combines juicy seasoned beef, caramelized onions, and a blend of Swiss and cheddar cheese, all grilled between buttery slices of Texas toast or rye bread. It’s a comforting, diner-inspired grilled cheese sandwich that’s quick, satisfying, and perfect for any occasion.
For best results, caramelize onions low and slow. Use thick, sturdy bread to prevent sogginess. Let patties rest on paper towels before assembling to keep bread crisp. Double up on cheese for extra gooeyness. Gluten-free and dairy-free adaptations are easy—just swap the bread and cheese as needed. Leftovers reheat best in a skillet or toaster oven.
