Instructions

1
In a small bowl, combine Worcestershire sauce, minced garlic, diced dill pickles, sliced scallions, mustard, mayonnaise, black pepper, and ketchup to create the smash sauce.
2
Mix all the sauce ingredients thoroughly until well combined. Set aside.
3
Preheat a griddle over high heat. Form the ground beef into four equal-sized balls and place them on the hot griddle.
4
Season the beef balls with salt. Using a sturdy spatula, smash each ball down as thinly as possible.
5
Cook for 1-2 minutes, until the edges are brown and crispy and the patties are bubbling.
6
Flip the patties, season the other side, and immediately top each with a slice of American cheese.
7
While the cheese melts, toast the potato buns on the griddle.
8
To assemble, place two cheesy patties on the bottom half of each toasted bun.
9
Top the patties with a generous amount of the prepared smash sauce.
10
Place the top bun on, press down gently, and serve immediately.

Tips & Notes

Pro tips

Form a loose, slightly larger patty than your final burger size; it will shrink when smashed, so start oversized to maintain proper dimensions.
Smash downward firmly and hold for 3–5 seconds to maximize surface contact with the hot griddle and develop the crispy, caramelized crust.
Toast the potato roll briefly on the griddle after the burger is done to add warmth and prevent sogginess from the sauce.
Season the beef generously with salt and pepper right before cooking; salting too early draws out moisture and reduces browning.

Substitutions

American cheese → Cheddar or Swiss cheese (adjust flavor intensity to taste)
Potato roll → brioche bun or pretzel roll (changes texture and flavor profile)
Worcestershire sauce → soy sauce or tamari (1 tbsp, for an umami-forward sauce)
English mustard → whole-grain or Dijon mustard (alters spice level slightly)

Storage & make-ahead

Store leftover smash sauce in an airtight container in the refrigerator for up to 3 days; cooked burgers are best enjoyed fresh but can be refrigerated and reheated gently on the griddle.

Equipment

griddle or cast-iron skillet · meat spatula (flat, sturdy)

Common Questions

Why use Wagyu beef for smash burgers?

Wagyu's higher fat content creates a juicier patty and renders beautifully on the griddle, producing deeper caramelization and richer flavor than standard ground beef.

How hot should the griddle be?

The griddle should be very hot (around 350–400°F) so the beef sears immediately and develops crispy, browned edges when smashed.

When do you smash the patty?

Press the patty firmly with a spatula 30–60 seconds after it hits the griddle, once the bottom has begun to set; smashing too early or too late prevents proper crust formation.

Can I make the smash sauce ahead?

Yes, mix all sauce ingredients (mayo, Worcestershire, mustard, ketchup, pickles, scallion, garlic) up to 2 days ahead and refrigerate in an airtight container.
