Burger

Toppings

Method

Preparing the Burger

  1. 1

    In a mixing bowl, combine 1 lb of ground beef with 1 tsp of salt and 1 tsp of black pepper. Mix gently until just combined, then form into one large patty, about 8 oz.

  2. 2

    Preheat a grill or skillet over medium-high heat. Once hot, place the burger patty on the grill and cook for about 4-5 minutes per side for medium-rare, or until your desired doneness is reached.

Caramelizing the Onion

  1. 3

    While the burger is cooking, slice the medium onion into thin rings.

  2. 4

    In a separate skillet, melt 2 tbs of butter over medium heat. Add the sliced onions and cook, stirring occasionally, for about 10-15 minutes until they are soft and caramelized.

Making the Dressing

  1. 5

    In a small bowl, combine 1 tbs of mayonnaise, 1 tbs of ketchup, 1 tsp of sweet pickle relish, and 1 tsp of Dijon mustard. Mix well until smooth.

Assembling the Patty Melt

  1. 6

    Once the burger is cooked, place 2 slices of Swiss cheese on top of the patty and let it melt for about 1 minute.

  2. 7

    To assemble the patty melt, spread the house-made Thousand Island dressing on one side of each slice of marble rye bread.

  3. 8

    Place the burger with melted cheese on one slice of bread, top with the caramelized onions, and then cover with the second slice of bread, dressing side down.

Grilling the Patty Melt

  1. 9

    In the same skillet used for the onions, add a little more butter if needed and place the assembled patty melt in the skillet.

  2. 10

    Grill the sandwich over medium heat for about 3-4 minutes per side, or until the bread is golden brown and crispy.
