Tips for Char, Spice, and Melted Cheese

  • Remove jalapeno seeds for a milder flavor.
  • Use different pepper varieties like poblano or anaheim for varied heat levels.
  • Swap ground beef for ground turkey or plant-based burger alternatives.

Store Smash Burgers to Keep ‘Em Juicy

  • Store the burger sauce in an airtight container in the refrigerator for up to 5 days, maintaining its fresh flavor and creamy consistency.
  • Keep caramelized onions and jalapenos in a separate sealed container in the refrigerator, which will stay delicious for 3-4 days and can be easily reheated.
  • When making burger patties in advance, separate each patty with parchment paper and store in a sealed container in the refrigerator for maximum 24 hours to maintain meat quality and prevent sticking.
  • If you have remaining burgers, wrap them individually in aluminum foil and refrigerate for up to 2 days. Reheat in a skillet on medium-low heat to preserve the crispy edges and prevent drying out.

FAQs

The technique involves pressing the beef ball into a thin patty on a hot skillet, creating crispy, caramelized edges that develop intense flavor and a unique texture different from traditional thick burger patties.

  • Can I use a different type of ground meat?

Yes, you can substitute ground beef with ground turkey or ground chicken, but the fat content might affect the burger’s crispiness and flavor, so choose a ground meat with at least 15-20% fat.

  • How do I prevent the burger patties from falling apart when smashing?

Ensure your skillet is very hot and use a sturdy metal spatula or burger press. Avoid overworking the meat when forming balls, and don’t move the patties too much during cooking to maintain their structure.

  • Is it necessary to use a cast-iron skillet?

While a cast-iron skillet provides the best heat retention and crispy results, you can use a heavy-bottomed stainless steel or carbon steel skillet as an alternative.

Ingredients

Scale
  • 1.5 lbs (680 g) high-quality 80% lean ground beef
  • 4 hamburger buns, split and toasted
  • 4 slices american cheese
  • 1 large yellow onion, thinly sliced (about 2 cups)
  • 1 large jalapeno chile, thinly sliced (about ½ cup)
  • 3 tbsps mayonnaise
  • 1.5 tbsps ketchup
  • 1 tsp Worcestershire sauce
  • 1 tsp canola oil
  • 1.25 tsps kosher salt
  • 0.75 tsp black pepper
  • 0.25 tsp garlic powder
  • 0.25 tsp kosher salt

Instructions

  1. Sauce Preparation: Whisk mayonnaise, ketchup, Worcestershire sauce, black pepper, garlic powder, and kosher salt in a small bowl. Refrigerate to intensify flavor profile.
  2. Vegetable Sautéing: Heat cast-iron skillet with canola oil over medium temperature. Introduce sliced onions and jalapenos, seasoning with salt and pepper. Caramelize onions and soften jalapenos until achieving a rich golden hue, approximately 10-15 minutes. Transfer aromatic mixture to a separate container.
  3. Meat Preparation: Gently form ground beef into 8 delicate balls, minimizing handling to preserve meat’s natural texture. Arrange on parchment-lined tray and chill before cooking.
  4. Burger Searing: Elevate skillet to smoking point. Carefully position beef balls without overcrowding. Utilize sturdy spatula to transform balls into ultra-thin, crispy-edged patties. Season with additional salt and pepper. Sear 2-3 minutes per side, ensuring optimal doneness. During final moments, adorn each patty with American cheese slice.
  5. Assembly and Serving: Toast hamburger buns and generously spread prepared sauce on inner surfaces. Position cheese-melted patty onto bottom bun. Garnish with caramelized onion-jalapeno mixture. Add optional complementary toppings. Complete with top bun and serve immediately while steaming hot.

Notes

  • Control Meat Temperature: Keep ground beef cold before smashing to ensure crispy, caramelized edges and prevent meat from becoming tough.
  • Master Smashing Technique: Use a heavy, flat spatula and press firmly but quickly to create thin, crispy-edged patties without overworking the meat.
  • Balance Spice Level: Remove jalapeno seeds for milder heat or keep them for extra kick; adjust according to personal spice tolerance.
  • Cheese Melting Trick: Cover patties with a lid during final moments of cooking to help cheese melt evenly and create a perfectly gooey texture.
