Smash Burger With Secret Sauce (Printable)

Crispy-edged smashed beef patties with melty cheese and tangy creamy secret sauce, ready in 25 minutes.

# What You'll Need:

→ For the smash burgers

01 - 1 lb ground beef, 80/20 blend (divide into four ~4 oz portions)
02 - 1 tsp kosher salt
03 - 1/2 tsp freshly ground black pepper
04 - 4 slices American cheese or cheddar
05 - 4 soft burger buns
06 - 2 tbsp unsalted butter (for toasting buns)
07 - 1 small red onion, thinly sliced
08 - 1 cup shredded iceberg lettuce
09 - 8 dill pickle chips

→ For the secret sauce

10 - 1/3 cup mayonnaise
11 - 1 1/2 tbsp ketchup
12 - 1 tbsp yellow mustard
13 - 1 tbsp finely chopped dill pickles
14 - 1 tsp white vinegar
15 - 1/2 tsp garlic powder
16 - 1/4 tsp smoked paprika
17 - Pinch cayenne pepper (optional)

# How to make it:

01 - Combine mayonnaise, ketchup, yellow mustard, finely chopped pickles, white vinegar, garlic powder, smoked paprika and a pinch of cayenne in a small bowl; whisk until uniform and refrigerate while you prepare the rest.
02 - Divide the ground beef into four even portions (about 4 oz each) and form loose balls without overworking to preserve tenderness.
03 - Heat a cast-iron skillet or griddle over high heat until shimmering and very hot; a properly heated surface is essential for a crisp, caramelized edge.
04 - Melt the butter in a separate skillet or on the griddle over medium heat and toast the buns, cut-side down, until golden; set aside warm.
05 - Arrange the beef balls on the hot surface with space between each to allow steam to escape and promote crisping.
06 - Using a sturdy metal spatula or burger press, press each ball firmly into a thin patty (approximately 1/4-inch thick); season immediately with kosher salt and freshly ground black pepper.
07 - Cook the patties undisturbed for about 2 minutes until the edges are deeply browned and crisp; flip, top each patty with a cheese slice, and cook 1 additional minute until the cheese has melted.
08 - Spread the secret sauce on both bun halves, layer shredded lettuce, pickle chips and sliced onion on the bottom bun, place the cheesy patty on top, cap with the toasted top bun, and serve immediately while hot.

# Recipe Expert Tips:

01 -
  • This secret sauce is so good, you’ll find yourself sneaking tastes with the spoon before the burgers are done.
  • It’s the closest I’ve ever come to that classic, cravable diner flavor without having to leave my kitchen.
02 -
  • If your pan isn’t hot enough, the burgers won’t get that signature crispy edge—they’ll just steam and lose their magic.
  • The secret sauce gets even better if you make it a little ahead and let those flavors mingle for thirty minutes.
03 -
  • Use parchment paper between beef and spatula for stick-free smashing and easy release.
  • Chill the meat balls in the fridge for ten minutes before cooking—they’re easier to handle and keep their shape just long enough for the perfect smash.
