Ingredients

The following ingredients have 4 Servings
  • 2 tablespoons Vegetable Oil (plus more for brushing)
  • 2 large Onions (finely chopped)
  • Kosher Salt (to taste)
  • 1/4 cup Mayonnaise (We always choose Duke's Mayonnaise)
  • 2 tablespoons Ketchup
  • 1 tablespoon Sweet Pickle Relish
  • 1/2 teaspoon White Vinegar
  • 2 pounds Ground Beef Chuck (preferably 60 - 80% lean)
  • 4 Hamburger Buns (split)
  • 1/4 cup sliced Dill Pickles
  • 3/4 cup Shredded Iceberg Lettuce
  • 4 to 8 thin slices Tomato
  • Freshly Ground Pepper (to taste)
  • 1/4 cup Yellow Mustard
  • 8 slices American Cheese

Instruction

  • Heat vegetable oil in a large skillet over medium-low heat.
  • Add onions and 3/4 teaspoon salt. Cover and cook, stirring occasionally, until golden and soft, about 30 minutes. (If the onions brown too quickly, reduce the heat to low.)
  • Uncover, increase the heat to medium high and continue to cook, stirring often, until caramelized, about 8 more minutes.
  • Add 1/2 cup water to the skillet, scraping up any browned bits from the bottom of the pan. Simmer, stirring, until the water evaporates, about 2 more minutes. Transfer to a bowl and set aside. (The onions can be made up to 3 days ahead; cover and refrigerate, then reheat before using.)
  • Mix mayonnaise, ketchup, relish and vinegar in a bowl. Set aside.
  • Shape beef into 8 patties, about 4 inches wide and 1/2-inch thick.
  • Heat a griddle or skillet over medium heat. Lightly brush with vegetable oil.
  • Toast the buns on the griddle, split-side down.
  • Spread each toasted bun bottom with about 1 tablespoon of the mayonnaise mixture.
  • Then top with a few pickles, some lettuce, 1 or 2 slices tomato and another dollop of the mayonnaise mixture. Set aside. (Keep the griddle hot.)
  • Season both sides of the patties with salt and pepper, to taste.
  • Working in batches, if necessary, put the patties on the griddle. Cook about 3 minutes.
  • Spread about 1 1/2 teaspoons mustard on the uncooked side of each patty.
  • Then flip and top each with 1 slice cheese.
  • Continue cooking about 2 more minutes for medium doneness.
  • Top 4 of the patties with caramelized onions.
  • Then cover with the remaining patties, cheese-side up.
  • Sandwich the double patties on the buns.
