how to make Jalapeño-Onion Smash Burgers

Ingredients:

  • 3 tablespoons mayonnaise
  • 1 1/2 tablespoons ketchup
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon kosher salt
  • 1 1/2 pounds high-quality 80% lean ground beef
  • 1 teaspoon canola oil
  • 1 large yellow onion, very thinly sliced (about 2 cups)
  • 1 large jalapeño chile, very thinly sliced (about 1/2 cup)
  • 1 1/4 teaspoons kosher salt, divided
  • 3/4 teaspoon black pepper, divided
  • 4 American cheese slices
  • 4 soft hamburger buns, split and toasted

Directions:

  1. Stir together all burger sauce ingredients in a small bowl. Cover and chill until you are ready to use it.
  2. Divide the beef into 8 (3-ounce) portions and shape each portion into a loose ball. Place them on a plate, cover, and chill while preparing the grill.
  3. Cut a 3-inch square of parchment paper and set it aside. Preheat the grill to high (450°F to 500°F). Place a large cast-iron skillet or griddle on the grill to preheat. Alternatively, you can heat a large cast-iron skillet or griddle on the stove over high heat.
  4. Drizzle the skillet evenly with oil. Depending on your skillet size, arrange onion slices in 8 small mounds (about 1/4 cup each), spacing them at least 2 inches apart. Top each onion mound with jalapeño slices (about 1 tablespoon each), and sprinkle evenly with 1/2 teaspoon salt and 1/4 teaspoon pepper. Cook undisturbed until the onions begin to brown, about 30 seconds to 1 minute.
  5. Place 1 meatball on each onion mound. Top with the parchment paper square, and press firmly to flatten using a sturdy spatula to form a 4-inch-wide patty. Remove the parchment paper. Repeat the process with the remaining meatballs and onion mounds.
  6. Sprinkle the smashed patties evenly with the remaining 3/4 teaspoon salt and 1/2 teaspoon pepper. Cook undisturbed until the patties begin to crisp around the edges, about 2 to 3 minutes.
  7. Flip the patties so that the onion-jalapeño mixture is on top. Place 1 cheese slice on each of 4 patties and continue cooking until the patties are well browned and the cheese is melted, about 1 minute and 30 seconds to 2 minutes. Top each cheese-covered patty with a plain patty to create 4 double stacks. Transfer each stack to a bottom bun.
  8. Spread about 1 tablespoon of burger sauce on each top bun and place them on top of the patties. Serve immediately.
