Method

Burger Preparation

  1. 1

    Prepare the Onion Jam

    Finely slice the onion. In a skillet over medium heat, cook the onion until caramelized, about 15-20 minutes. Stir occasionally and add a pinch of salt.

  2. 2

    Cook the Pancetta

    In the same skillet, add the pancetta slices and cook until crispy, about 3-4 minutes. Remove and set aside.

  3. 3

    Form the Patties

    Divide the Wagyu ground beef into two equal portions and form into patties. Season both sides with salt and black pepper.

  4. 4

    Cook the Patties

    In the skillet, over medium-high heat, cook the patties for about 3-4 minutes on each side for medium-rare. During the last minute of cooking, place a slice of Fontina cheese on each patty to melt.

  5. 5

    Prepare the Pesto Mayo

    In a small bowl, mix the mayonnaise and pesto together until well combined.

  6. 6

    Assemble the Smashburger

    Spread the pesto mayo on the bottom half of the seeded brioche bun. Place the first patty on top, followed by a layer of onion jam and crispy pancetta. Add the second patty on top and finish with the top half of the brioche bun.

  7. 7

    Serve

    Serve the Lago Smashburger immediately with your choice of side.
