07 -
680g high-quality 80% lean ground beef
08 -
1 teaspoon canola oil
09 -
1 large yellow onion, thinly sliced (about 2 cups)
10 -
1 large jalapeño chile, thinly sliced (about 1/2 cup)
11 -
1 1/4 teaspoons kosher salt, divided
12 -
3/4 teaspoon black pepper, divided
13 -
4 slices American cheese
14 -
4 hamburger buns, split and toasted
# Steps:
01 -
In a small bowl, combine mayonnaise, ketchup, Worcestershire sauce, black pepper, garlic powder, and kosher salt. Mix thoroughly, cover, and refrigerate until needed.
02 -
Heat a large cast-iron skillet over medium heat and add the canola oil. Add sliced onions and jalapeños, seasoning with ¼ teaspoon kosher salt and ¼ teaspoon black pepper. Cook until onions are caramelized and jalapeños softened, approximately 10-15 minutes. Transfer to a bowl and reserve.
03 -
Divide ground beef into 8 equal portions (approximately 85g each). Gently form each portion into a loose ball without overworking the meat. Place balls on a parchment-lined baking sheet and refrigerate until ready to cook.
04 -
Wipe the skillet clean and heat over high heat until slightly smoking. Place beef balls into the hot skillet without overcrowding. Using a sturdy spatula or burger press, firmly flatten each ball into a thin patty. Season with remaining kosher salt and black pepper. Cook until edges are crispy and center is cooked through, about 2-3 minutes per side. During the final minute, top each patty with American cheese to melt.
05 -
Spread a generous amount of burger sauce on both cut sides of the toasted hamburger buns. Place a cheese-topped patty on each bottom bun. Top with a spoonful of caramelized onion and jalapeño mixture. Cover with top bun and serve immediately.
# Notes:
01 -
For best results, use a cast-iron skillet to achieve the signature crust on the smash burgers.
02 -
The key to a proper smash burger is pressing firmly with a metal spatula within the first 30 seconds of cooking.
