Burger Ingredients

Method

Burger Preparation

  1. 1

    Prepare the Caramelized Onions

    In a skillet over medium heat, add a tablespoon of olive oil. Add sliced onions and a pinch of salt. Cook, stirring occasionally, for about 15-20 minutes or until the onions are soft and golden brown. Drizzle with balsamic vinegar and cook for an additional 5 minutes. Remove from heat and set aside.

  2. 2

    Make the Truffle Aioli

    In a small bowl, combine mayonnaise, truffle oil, minced garlic, lemon juice, and salt to taste. Stir until well blended and set aside.

  3. 3

    Form and Cook the Patties

    In a mixing bowl, combine ground beef, salt, and black pepper. Divide into 4 equal portions and form into patties. Preheat a grill or skillet over medium-high heat and cook patties for about 4-5 minutes on each side for medium doneness. In the last minute of cooking, place a slice of fontina cheese on each patty to melt.

  4. 4

    Assemble the Burgers

    Toast the burger buns lightly. Spread a generous amount of truffle aioli on the bottom bun. Place the cooked patty with melted cheese on top, followed by a scoop of balsamic caramelized onions and a handful of arugula. Top with the other half of the bun.

  5. 5

    Serve

    Serve the burgers hot with your choice of sides.
