  • 1 Large Yellow Onion Very thinly sliced
  • 4 Slices American Cheese
  • 4 Pieces Burger Buns
  • 1 tsp Kosher Salt

  • 1/2 cup mayonnaise

  • 1 tbsp sweet pickle relish (or finely chopped pickles)

Instructions
 

  • Preheat your griddle to medium-high heat (around 400°F).
  • Divide the ground beef into 4 loosely packed balls. Do not overwork the meat.
  • Place each beef ball on the griddle and immediately top with a generous handful of thinly sliced onions.
  • Smash firmly using a sturdy spatula until very thin. Press the onions directly into the beef.
  • Season with salt and pepper.
  • Cook for 2–3 minutes until the edges are deeply browned and crispy.
  • Flip carefully so the onions are now facing down. Cook another 1–2 minutes.
  • Add cheese and let it melt.
  • Toast buns lightly with butter.
  • Assemble and serve immediately.
    • Sauce: Combine all ingredients in a small bowl, whisk until smooth, and chill for at least 15 minutes to allow flavors to meld. 
    “Smashing thin and pressing the onions into the beef is what gives this burger its signature flavor and crispy texture.”
