680g (1 1/2 pounds) 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
# Instructions:
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. Add canola oil, then sliced onions and jalapeños. Season with ¼ teaspoon kosher salt and ¼ teaspoon black pepper. Cook, stirring occasionally, until onions caramelize and jalapeños soften, about 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 in the hot skillet, ensuring not to overcrowd. Using a sturdy spatula or burger press, firmly smash each ball into a thin patty. Season with remaining salt and pepper. Cook until edges crisp and center is cooked through, about 2-3 minutes per side. During the final minute, place cheese slices on patties to melt.
05 -
Spread burger sauce generously on both sides of toasted buns. Place a cheese-topped patty on each bottom bun. Top with caramelized onion and jalapeño mixture. Add any additional desired toppings and cover with the top bun. Serve immediately while hot.
# Notes:
01 -
For maximum flavor, allow the onion-jalapeño mixture to properly caramelize. The slow cooking process brings out their natural sweetness, creating a perfect contrast to the savory beef.
