Description
Juicy smash burgers enhanced with zesty jalapeños and caramelized onions for a bold flavor experience.
Ingredients
- For the Burger Sauce:
- 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
- For the Burgers:
- 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
Instructions
- In a small bowl, combine the mayonnaise, ketchup, Worcestershire sauce, black pepper, garlic powder, and kosher salt to create the burger sauce. Cover and chill until ready to use.
- Divide the beef into eight 3-ounce portions and shape each into a loose ball on a plate. Cover and chill while preparing the grill.
- Cut a 3-inch square of parchment paper and set it aside. Preheat the grill to high. Place a cast-iron skillet or griddle on the grill to heat.
- Drizzle the skillet with canola oil. In batches, arrange onion slices into eight small mounds (about 1/4 cup each), spacing them at least two inches apart. Top each mound with jalapeño slices and sprinkle them with 1/2 teaspoon salt and 1/4 teaspoon black pepper. Cook undisturbed for about 30 seconds to 1 minute until the onions begin to brown.
- Place one meatball on each onion mound, then cover with the parchment paper square. Press firmly to flatten the balls into 4-inch-wide patties using a sturdy spatula or burger press. Remove the parchment paper and repeat with the remaining meatballs.
- Sprinkle the smashed patties evenly with the remaining 3/4 teaspoon of salt and 1/2 teaspoon of black pepper. Cook undisturbed for 2 to 3 minutes until the edges start to crisp. Flip the patties so that the onion-jalapeño mixture is on top.
- Add a slice of American cheese to each of four patties, continuing to cook until well-browned and the cheese has melted, approximately 1 minute and 30 seconds to 2 minutes.
- Top each cheese-covered patty with a plain patty to create four double stacks. Transfer each stack to the bottom half of a toasted hamburger bun.
- Spread about 1 tablespoon of the burger sauce on each top bun and place on the patties. Serve immediately.
Notes
Select fresh and high-quality ingredients for best results. Adjust jalapeño slices according to heat preference.
