Onion Smash Burger

Divide the ground beef into four 3-ounce balls. Using a mandoline or a very sharp knife, slice the onion as thinly as possible.

In a small bowl, make the burger sauce by combining the light mayonnaise, ketchup, yellow mustard, hot sauce, and a splash of Worcestershire sauce. Season with salt and pepper to taste and mix well.

Preheat a griddle or large cast-iron skillet over medium-high heat. Place the beef balls onto the hot surface.

Top each beef ball with a large handful of the thinly sliced onions.

Using a sturdy spatula or burger press, smash each ball down firmly to create a thin patty, pressing the onions into the meat. Season the tops of the patties with salt and pepper.

Cook for 2-3 minutes until a deep brown crust forms on the bottom, then flip the patties.

Drizzle the remaining Worcestershire sauce over the cooked patties. Top each patty with a slice of American cheese and allow it to melt, about 1 minute.

Toast the brioche buns. Spread a generous amount of burger sauce on the inside of both the top and bottom buns.

Layer dill pickle slices on the bottom bun, then stack two cheesy onion patties on top. Place the top bun on and serve immediately.
