Ingredients

Secret Spread

  • 0.25 cup Mayonnaise
  • 2 tablespoons Ketchup
  • 1.5 tablespoons Sweet pickle relish — finely chopped
  • 0.5 teaspoon White vinegar
  • 0.5 teaspoon Granulated sugar

Caramelized Onions

  • 1 large Yellow onion — finely diced
  • 1 tablespoon Unsalted butter
  • 1 pinch Salt

Burger Components

  • 0.5 pound Ground beef (80/20) — divided into 4 equal portions
  • 2 tablespoons Yellow mustard — for mustard-frying the patties
  • 4 slices American cheese — classic processed cheese melts best
  • 2 whole Hamburger buns — plain white sponge dough or brioche
  • 4 leaves Iceberg lettuce — torn to bun size
  • 2 slices Tomato — thickly sliced
  • 8 slices Dill pickle chips
  • 1 teaspoon Salt and black pepper — to taste

Instructions

  1. In a small bowl, whisk together the mayonnaise, ketchup, sweet pickle relish, white vinegar, and sugar. Cover and refrigerate until ready to use.

    ~5 min
    Making the spread ahead of time allows the flavors to meld together.
  2. Melt the butter in a skillet over medium-low heat. Add the finely diced onions and a pinch of salt. Cook, stirring occasionally, until the onions are deeply browned and caramelized, about 20-25 minutes. If they start to dry out, add a splash of water. Remove from pan and set aside.

    ~25 min
    Low and slow is the key to perfectly sweet, jammy onions.
  3. Form the ground beef into 4 thin patties, about 2 ounces each, slightly larger than your buns as they will shrink. Generously season one side with salt and pepper.

    ~5 min
    Keep the meat cold until right before cooking to ensure a good crust.
  4. Heat a cast iron skillet or griddle over medium-high heat. Toast the cut sides of the hamburger buns until golden brown. Set aside.

    ~2 min
    You can add a tiny bit of butter or mayo to the buns for a better toast, though traditionally they are dry-toasted.
  5. Place the patties in the hot skillet, seasoned side down. Immediately spread about 1/2 tablespoon of yellow mustard onto the raw, upward-facing side of each patty. Cook for 2-3 minutes until the bottom develops a dark, crispy crust.

    ~3 min
    Press down firmly on the patties with a spatula right when they hit the pan to maximize contact.
  6. Flip the patties (so the mustard side is now down). Immediately place a slice of American cheese on top of each patty. Divide the caramelized onions onto two of the patties. Cook for another 1-2 minutes until the cheese is completely melted.

    ~2 min
    Stack the non-onion patty on top of the onion patty while still in the pan to melt them together.
  7. Assemble the burgers: Spread a generous amount of the secret spread on the toasted bottom buns. Layer with dill pickles, a slice of tomato, and iceberg lettuce. Place the double-patty stacks on top of the lettuce, and cover with the toasted top buns.

    ~3 min
    The order of ingredients is key to the authentic experience: bottom bun, spread, pickles, tomato, lettuce, patties, top bun.

Tips & Storage
  • For the ultimate fast-food feel, wrap the assembled burgers halfway in parchment paper or foil before eating.
  • Do not overwork the ground beef when forming patties; handle it as little as possible for a tender bite.
  • Storage: Burgers are best enjoyed immediately. Store leftover components (patties, onions, spread) in separate airtight containers in the refrigerator for up to 3 days.
