Main Ingredients

Smash Sauce

Method

Preparation of Ingredients

  1. 1

    Caramelize the Onions

    Slice the medium onion thinly. In a skillet, heat 1 tablespoon of oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are soft and golden brown, about 15 minutes.

  2. 2

    Cook the Bacon

    In the same skillet or another, cook the bacon slices over medium heat until crispy. Remove them from the skillet and let them drain on paper towels. Once cooled, crumble the bacon into small pieces.

Prepare the Smash Sauce

  1. 3

    Mix the Smash Sauce

    In a bowl, combine the mayonnaise, ketchup, yellow mustard, pickle relish, garlic powder, onion powder, salt, and black pepper. Mix well until all ingredients are combined.

Cooking the Burger

  1. 4

    Form and Cook the Patties

    Divide the ground beef into two equal portions and form them into patties. Heat a skillet or griddle over high heat. Place the patties on the hot surface and smash them down using a spatula to create a flat surface. Season with salt and black pepper. Cook for about 3-4 minutes on one side.

  2. 5

    Add Cheese

    Flip the patties and immediately place the cheddar cheese on top of each patty. Cook for another 2-3 minutes, or until the cheese is melted and the burger is cooked to your desired doneness.

Assembly

  1. 6

    Assemble the FAT BOY

    Spread a generous amount of smash sauce on the bottom half of each burger bun. Place the cooked burger patty with melted cheddar on top. Add the crumbled bacon and caramelized onions. Top with the other half of the burger bun. Serve immediately.
