Burger Ingredients

Method

Cooking Directions

  1. 1

    Caramelize the Onions

    In a skillet, heat olive oil and butter over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions are golden brown and caramelized, about 20 minutes. Set aside.

  2. 2

    Prepare the Burger Patties

    In a mixing bowl, combine the ground beef, salt, and black pepper. Form into two equal-sized patties.

  3. 3

    Cook the Burger Patties

    In the same skillet used for the onions, increase the heat to medium-high. Cook the burger patties for about 4-5 minutes on each side, or until they reach your desired doneness.

  4. 4

    Add the Cheese

    In the last minute of cooking, place a slice of fontina cheese on each patty and cover the skillet to help melt the cheese.

  5. 5

    Assemble the Burger

    Toast the burger buns lightly. On the bottom half of each bun, spread a generous amount of the special sauce, then add the cooked burger patty with melted cheese, followed by caramelized onions, sliced tomatoes, and pickles. Top with the other half of the bun.

  6. 6

    Serve

    Cut the burger in half if desired and serve immediately with your choice of sides.
