A crispy, cheesy, savory twist on the diner classic, these Grilled Cheese Patty Melts layer juicy ground beef, caramelized onions, and melty cheese between golden grilled bread—perfect for comfort food lovers.

8 slices rye or sourdough bread
1 large yellow onion, thinly sliced
8 slices American or provolone cheese
