Method

Cooking Instructions

  1. 1

    Caramelize the Onions

    Heat olive oil in a skillet over medium heat. Slice the onion thinly and add to the skillet. Cook, stirring occasionally, until the onions are golden brown and caramelized, about 15-20 minutes. Season with salt and pepper to taste.

  2. 2

    Prepare the Patties

    While the onions are caramelizing, divide the ground beef into two equal portions and shape them into patties. Season both sides with salt and pepper.

  3. 3

    Cook the Patties

    In a grill or skillet over medium-high heat, cook the patties for 3-4 minutes on one side. Flip the patties, place a slice of American cheese on each, and cook for another 3-4 minutes or until the cheese is melted and the patties are cooked to your desired doneness.

  4. 4

    Assemble the Burger

    Toast the Füdmill sesame buns lightly. On the bottom bun, spread the Kewpie mayonnaise. Add the lettuce leaves, followed by the cooked patties with melted cheese, caramelized onions, and dill pickles. Top with the other half of the bun.

  5. 5

    Serve

    Serve the burgers immediately with your choice of sides.
