How to Make the Wursthall Smashburger: Step-by-Step Guide
Learn how to craft lacy-edged patties with deep browning and bursts of savory richness.
How to Make the Wursthall Smashburger
If you’ve ever craved the signature crispy, lacy-edged smashburger served at Wursthall, you’re in the right place. Chef and food writer J. Kenji López-Alt has mastered a burger that delivers bold flavor, crunchy texture, and juicy meat—using simple methods and accessible ingredients. This guide will walk you through every essential step, technique, and tip to recreate the Wursthall smashburger at home.
Why the Smashburger Technique?
The smashburger method is all about maximizing surface contact: pressing a ball of ground beef onto a hot surface creates a deeply browned, crisp crust while keeping the interior tender and juicy. That lacy edge and golden crust are what set the smashburger apart from thicker patties.
- Crispy edges from direct contact between beef and hot griddle
- Quick cooking for juicy, flavorful meat
- Simple seasoning allows the beef flavor to shine
Equipment You’ll Need
You don’t need commercial kitchen tools to make a great smashburger. Here’s what J. Kenji López-Alt recommends for best results:
- Heavy cast-iron skillet or a flat griddle (alternatively use stainless steel)
- Sturdy metal spatula with a sharp edge for scraping
- Small weight (like another pan or a burger press)
- Parchment paper sheets to prevent sticking
- Razor scraper for releasing the crusty burger from the pan
Choosing and Preparing the Beef
The heart of a smashburger is quality ground beef. Kenji recommends freshly ground, coarse, high-fat chuck and/or brisket (ideally an 80% lean / 20% fat blend). The goal is a beefy flavor and enough fat to brown and crisp beautifully.
- Weigh out two balls of beef, each about 2.25 ounces for a double patty.
- Do not compress—lightly formed balls hold together just enough to smash but cook tender.
- Season generously with salt and freshly ground black pepper on both sides.
Step-by-Step Smashburger Cooking Process
Follow these exact steps for an authentic Wursthall smashburger:
- Toast the Bun First:
- Burger cooks much faster than the bun toasts.
- Use clarified butter or straight butter on the bun.
- Toast until golden brown and crisp.
- Season the Beef:
- Coarse ground beef balls, seasoned with salt and pepper.
- Place balls bottom-side up for easy smashing.
- Smash the Patties:
- Heat skillet or griddle until very hot.
- Place beef balls on the hot surface.
- Cover each ball with parchment paper.
- Using spatula and weight, press down hard, especially on the edges to get those signature lacy, crispy bits.
- Cook and Flip:
- Burger cooks about 90% on the first side.
- Using razor scraper, release crust from pan.
- Flip quickly, add American cheese while still hot.
- Finish & Assemble:
- Stack double patties and cheese on the bottom bun.
- Add classic toppings: shredded iceberg lettuce, slivered onions, and plenty of kosher dill pickles.
- Top with homemade or good-quality mayonnaise (egg yolks, lemon juice, garlic, canola, olive oil, and salt).
- Cap with toasted top bun and serve immediately.
Table: Wursthall Smashburger Components
| Component | Description | Tips |
|---|---|---|
| Bun | Soft, toasted with butter | Toast first, use clarified or straight butter |

Expert Tips for the Perfect Smashburger
- High Heat is Essential: Only a properly hot pan develops the lacy crust.
- Parchment Trick: Parchment paper between spatula and burger prevents sticking and keeps crust intact.
- Don’t Overwork the Beef: Minimal handling preserves tenderness.
- Double Up for Full Experience: Two thin patties equal one perfectly thick burger with doubled crust.
- Build the Burger Smartly: Toppings beneath the patties hold crunch and juices where you want them.

Choosing the Right Cheese
American cheese is the classic choice for smashburgers, prized for its melting properties, creamy texture, and ability to envelop the crust with salty, rich goodness. Skip aged or firm cheeses—only American achieves the quintessential smashburger melt.
- Add cheese immediately after flipping the burger.
- Layers between hot patties help cheese melt fully.
Building the Burger: Toppings and Sauces
The Wursthall smashburger is layered for contrast and flavor:
- Mayonnaise: Made fresh, with egg yolks, lemon, garlic, canola and olive oils, and salt. Adds richness and tang.
- Shredded iceberg lettuce: For cool crunch beneath the hot patty.
- Slivered onions: Mild sharpness and texture.
- Kosher dill pickles: Acidity to balance beef and cheese.
Kenji recommends piling toppings on the bottom bun so juices run downward and crunch stays intact.
Troubleshooting Common Smashburger Challenges
- Meat Sticks to Pan: Use parchment paper, scrape gently with a razor scraper.
- Patties Tear or Crumble: Don’t panic: the coarsely ground beef is held together loosely; American cheese binds the burger once stacked.
- Buns Soggy: Always toast thoroughly, pile toppings low, and assemble quickly.
- Thin/Uneven Patties: Smash evenly from center out and focus on edges.
Frequently Asked Questions (FAQs)
Q: Can I use a regular metal spatula if I don’t have a razor scraper?
A: Yes. While a razor scraper helps lift the crust, a sturdy metal spatula with a sharp edge will work—just scrape aggressively and quickly.
Q: What’s the best beef blend?
A: A coarse grind of chuck or brisket with at least 20% fat is ideal. Ask your butcher for fresh ground beef; avoid preformed patties.
Q: Can I use another cheese besides American?
A: For authentic texture and flavor, American cheese is recommended, but processed cheddar works in a pinch. Firmer cheeses won’t melt as well.
Q: Is parchment paper really necessary?
A: Parchment creates a barrier that prevents sticking and helps maintain the crust. If you don’t have it, oil the pan well and use a flexible spatula.
Q: Can I prep my toppings ahead?
A: Yes. Slice onions, shred iceberg, and cut pickles before cooking so you can assemble your burger immediately after patties are done.
Variations and Customizations
- Single Patty: Works great for smaller appetites—use the same smash technique with a slightly larger beef ball.
- Bun Options: Swap for potato rolls, buttermilk buns, or classic white hamburger buns.
- Toppings Galore: Try jalapeños, grilled mushrooms, or swap mayo for spicy sauce.
- Cheese Swaps: For a twist, layer with jalapeño jack or smoked gouda after flipping.
