Classic Patty Melt

These cast-iron melts are comfort food at its finest.

Ingredients

  • 4 tablespoons canola oil, divided
  • 1 large yellow onion, thinly sliced (about 4 cups)
  • 1 ½ teaspoons kosher salt, divided
  • 1 ¼ pounds ground chuck
  • ½ teaspoon black pepper
  • ¼ cup mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 tablespoon barbecue sauce
  • 1 tablespoon ketchup
  • 3 ounces sharp yellow Cheddar cheese, shredded (about ¾ cup)
  • 8 (¾-inch-thick) sourdough bread slices
  • 4 Swiss cheese slices
  • 4 tablespoons butter, divided

Directions

  1. Heat 2 tablespoons of the oil in a medium skillet over medium. Add onion and ½ teaspoon of the salt. Cook, stirring often, until golden brown and soft, about 20 minutes. Set aside.

  2. Meanwhile, divide ground beef into 4 portions. Press each into a flat, ¼-inch-thick patty. Sprinkle with pepper and remaining 1 teaspoon salt.

  3. Heat remaining 2 tablespoons oil in a large cast-iron skillet over medium-high. Cook 2 patties at a time, pressing gently, until browned but still pink in the center, 2 minutes per side. Transfer to a plate.

  4. Stir together mayonnaise, mustard, barbecue sauce, and ketchup in a small bowl until combined.

  5. Wipe out cast-iron skillet; reduce heat to medium. Divide Cheddar among 4 of the bread slices; top each with a patty, caramelized onions, Swiss cheese slice, mayonnaise mixture, and remaining bread. Melt 2 tablespoons of the butter in skillet. Place 2 sandwiches in hot butter; cook (with another skillet on top of sandwiches to weigh them down) until golden brown and cheeses are melted, about 3 minutes per side. Repeat with remaining 2 tablespoons butter and 2 sandwiches.
