Aunt Sheila would slide these onto the table and somehow they’d disappear before the sweet tea even hit the glasses.

These southern patty melt sandwiches are the kind of thing an aunt like Sheila would slide onto the table, and they’d vanish before the sweet tea even made it out of the fridge. Think diner-style patty melt meets church-supper casserole: buttery toast, well-seasoned ground beef, sweet onions, and plenty of Swiss cheese, all baked off on sheet pans for a crowd. Patty melts trace back to mid-20th-century diners, but this version leans into Southern practicality—simple pantry ingredients, generous portions, and a method that lets you feed a tableful of people without standing over a griddle.

Serve these patty melts hot from the sheet pans with classic Southern sides: a bowl of potato chips or kettle-cooked crisps, a simple vinegar or mayo-based coleslaw, and sliced dill pickles on the side. A tomato-cucumber salad or a platter of fresh summer tomatoes with a little salt and pepper cuts through the richness nicely. For drinks, sweet tea is the obvious partner, but a cold lager or sparkling lemonade works just as well. If you want to stretch the meal, add a pan of baked beans or roasted potatoes and let everyone help themselves right from the counter.
