Burger Patties

Cheese and Onions

Catalina Secret Sauce

Burger Assembly

Method

Prepare the Secret Sauce

  1. 1

    Make the Catalina Sauce

    In a small bowl, combine mayonnaise, ketchup, sweet pickle relish, Dijon mustard, and garlic powder. Mix until smooth and set aside.

Caramelize the Onions

  1. 2

    Cook the Onions

    Slice the large onion thinly. In a skillet, melt butter over medium heat. Add the onions and a pinch of salt, cooking them slowly for about 15-20 minutes until they are golden brown and caramelized. Stir occasionally to prevent sticking.

Prepare the Burger Patties

  1. 3

    Form the Patties

    Divide the Linz American Wagyu beef into two equal portions of 4 oz each. Gently form them into balls, being careful not to overwork the meat. Season both sides with kosher salt and black pepper.

  2. 4

    Smash the Patties

    Heat a skillet or griddle over high heat until very hot. Place the meat balls in the skillet and immediately smash them down with a spatula to about 1/2 inch thick. Cook for about 2-3 minutes until browned, then flip the patties.

  3. 5

    Add Cheese

    After flipping, place a slice of sharp white cheddar cheese on each patty. Cook for an additional 1-2 minutes until the cheese is melted and the patties are cooked to your desired doneness.

Assemble the Burgers

  1. 6

    Build the Burger

    Toast the burger buns lightly on the grill or in a toaster. On the bottom half of each bun, place a lettuce leaf, followed by the smashed wagyu patty with melted cheddar, a generous portion of caramelized onions, a slice of tomato, and pickles. Drizzle with the Catalina secret sauce. Top with the other half of the bun.
