  • 6 tablespoons salted butter (divided)
  • 1 large Vidalia onion (thinly sliced)
  • Kosher salt
  • Pepper
  • 1 1/2 pounds ground beef
  • 3 tablespoons ketchup
  • 2 tablespoons Worcestershire sauce
  • 8 slices bread - my favorites are rye and sourdough
  • 8 to 12 slices of cheese - provolone, cheddar, American, and pepper jack are good options


  1. Heat a large sauté pan over medium low heat. Add 2 tablespoons of butter and the thinly sliced onion. Sprinkle with salt and pepper and sauté for 20 to 25 minutes or until the onions a softened and are golden brown. Remove from the pan to a plate and cover with foil.

  8. Put 1/4 of the caramelized onions on top of the burger.
  9. Top the onions with another slice of cheese.
  10. Place the remaining slice of bread butter side up with the cheese.
  11. Heat the sauté pan or panini press to medium heat.
  12. Cook the patty melts until lightly brown on each side and the cheese is melted, about 3 to 4 minutes for each side.
  13. Remove from pan and cut in half and serve.


  • The key to perfectly caramelized onions is to cook them in butter and low and slow. If you cook them too quickly over too high a heat, they with burn.
  • Use an assembly line to put the patty melts together. Butter one side of each slice of bread. Top half of the slices of bread with a slice of cheese. Add extra cheese if you like your sandwiches extra cheesy. Top the cheese with a burger and some of the caramelized onions. Add another slice a cheese and the top with a slice of buttered bread.
  • Use either a panini press or a sauté pan to toast the patty melts a delicious golden and crispy brown.
