What you'll need
- Cast iron skillet — Sears better than any non-stick; naturally non-stick once seasoned.
- Enameled Dutch oven — For braises, roasts, and one-pot mains.
- Instant-read thermometer — The only reliable way to nail doneness without guessing.
Instructions
- Divide the beef into 4 equal loose balls — do not compress or overwork them. Season the outsides with salt and pepper just before cooking.
- Make the sauce: whisk the egg yolk, mustard, honey, garlic powder, and smoked paprika in a small bowl. While whisking constantly, add the 1/2 cup avocado oil in a slow, steady stream until thick and emulsified. Stir in the tomato paste and chopped pickles. Refrigerate until assembly.
- Heat a cast-iron skillet over medium-high heat until very hot, then add 1 tbsp avocado oil.
- Place the beef balls in the skillet and immediately smash them flat with a sturdy spatula — the thin, crusty smashed patty is the ShackBurger signature. Sear 2–2.5 minutes until a deep brown crust forms, flip, top each patty with a slice of cheddar, and cook 1–2 minutes more until the cheese melts and the beef reaches 160°F.
- Slice buns and lightly toast them in the skillet with a small pat of butter.
- Assemble: sauce on the bottom bun, then lettuce, a tomato slice, the sliced red onion if desired, the cheese-topped patty, and a little more sauce on the top bun.
FAQ
Why use pasture-raised eggs over regular ones?
Pasture-raised eggs come from chickens that have access to the outdoors and a more natural diet, resulting in better nutritional value and taste.
What makes sourdough buns different for this burger?
Artisan sourdough buns are made with traditional methods using a live yeast starter, making them naturally leavened without the use of commercial yeasts or additives.
