Full Ingredients
For the Double Steakburgers
- 1 lb (454 g) ground beef, 80/20
- 1 1/4 tsp kosher salt (Diamond Crystal; use 3/4 tsp if Morton Salt)
- 1/2 tsp freshly ground black pepper
- 8 slices American cheese
- 4 soft hamburger buns
- 2 tbsp unsalted butter, softened (for toasting buns)
- 1/3 cup (50 g) finely diced white onion
- 1/2 cup dill pickle chips (16–20 chips)
- 1/4 cup (60 ml) yellow mustard
Optional Shoestring Fries
- 2 large russet potatoes (about 1.5 lb/680 g), cut into 1/8 in (3 mm) matchsticks
- 1 quart (950 ml) neutral oil (canola or peanut) for frying
- 1 tsp fine salt, or to taste

Step-by-Step Instructions
Step 1: Prep toppings and seasoning
Finely dice the white onion and set aside. Stir together the kosher salt and black pepper in a small bowl. Split the buns and spread 1/2 tbsp butter on the cut side of each bun.
Step 2: Portion and chill the beef
Divide the ground beef into eight equal 2 oz (57 g) portions and roll into loose balls—do not compress tightly. Keep the beef refrigerated until the pan is ripping hot; colder meat smashes and crisps better.
Step 3: Preheat griddle and toast buns
Set a cast-iron griddle or heavy skillet over medium-high heat until the surface reaches 450°F (use an infrared thermometer if you have one). A water droplet should dance and evaporate in under 2 seconds. Toast buns, buttered side down, until golden brown, 30–60 seconds. Keep nearby.
Step 4: Smash and sear the first side
Working in batches, place two beef balls per burger onto the hot surface, leaving space between. Immediately lay a small square of parchment on each ball and press with a stiff metal spatula or burger press to about 1/8 in (3 mm) thickness, maintaining firm pressure for 10–15 seconds to set the lacy edges. Sprinkle each patty with a generous pinch of the salt–pepper mix. Do not move the patties. Sear until the edges are deeply browned and frilly, about 90 seconds.
Step 5: Flip, add cheese, and finish
Using a very thin, sharp-edged metal spatula, scrape under each patty to release the crust cleanly and flip. Top each patty immediately with a slice of American cheese. Cook 30–45 seconds more, until the cheese melts and the second side is cooked through. For well-done, you may cook to an internal temperature of 160°F.
Step 6: Build the Original Double
Place two cheese-topped patties on each bottom bun. Spoon or squeeze about 2 tsp yellow mustard on the top bun. Add 4–5 dill pickle chips and about 1 tbsp diced onion over the patties. Cap with the mustard-smeared top bun. Serve right away while the edges are shatter-crisp.
Step 7: Optional shoestring fries
Cut potatoes into 1/8 in matchsticks. Soak in cold water for 20 minutes to rinse excess starch. Drain and dry thoroughly in clean towels. Heat oil to 350°F in a deep pot. Fry in small batches until pale golden and crisp, 1.5–3 minutes. Drain on a rack or paper towels and immediately season with fine salt. Serve alongside the burgers.
Pro Tips
- Smash within 10 seconds of the beef hitting the pan to maximize browning and those signature lacy edges.
- Use parchment squares to prevent sticking and to help you press very thin without tearing.
- A thin, sharp-edged metal spatula is essential for releasing the crust cleanly before flipping.
- Keep patties small (2 oz) and cook in batches to avoid crowding and temperature drops.
- Diamond Crystal salt is flakier than Morton; if using Morton, reduce the amount as noted to avoid oversalting.
Variations
- Onion-fried patties: Scatter a tablespoon of very thinly sliced onions on the griddle, set a beef ball on top, then smash. The onions caramelize into the crust.
- Cheese strategy: For a gooier center, place both cheese slices between the two patties and cover with a lid for 15 seconds to steam-melt.
- California style: Add shredded lettuce, tomato, and a light swipe of mayo while keeping the mustard–pickle–onion vibe.
Storage & Make-Ahead
These burgers are best eaten immediately; the crispy edges soften as they sit. You can portion beef balls up to 24 hours in advance and refrigerate tightly covered. Dice onions and slice pickles up to 2 days ahead. Butter the buns and keep covered at room temperature for up to 8 hours. For fries, cut and keep in cold water up to 8 hours; dry thoroughly before frying. Reheating burgers will not recreate the original texture, but you can re-crisp patties in a hot skillet for 45–60 seconds per side and re-toast the buns.
