Protein Style

  • 460 kcal
  • Any burger can be ordered this way

Any burger with the bun replaced by a wrap of whole lettuce leaves. The official figure here is for a Double-Double ordered this way, 150 calories lighter than the regular one. It is messier than it sounds, so keep the paper wrapper on and eat it top-down. Low-carb diners made it popular long before bunless burgers were fashionable.

The story

In-N-Out started wrapping burgers in lettuce instead of a bun in the 1970s, long before low-carb eating had a name attached to it, because customers asked. It stayed a word-of-mouth order for decades, part of the same unofficial menu as Animal Style, until the company put it on its website. The build is unchanged: the same patty, cheese, spread, tomato and onion, held in a folded lettuce cup that leaks precisely as much as you would expect.

There is no copycat of the Protein Style yet. Until there is, these recipes on the site come closest to it, judged by what goes into the bun.

About In-N-Out Burger

  • United States
  • Since 1948
  • $

In-N-Out has ignored almost every rule of fast food for more than seventy years. Harry and Esther Snyder opened a tiny drive-thru stand in Baldwin Park, California, in 1948, and the family still owns every location. No franchising, no freezers, no microwaves, and a menu that has barely grown: three burgers, fries, shakes and drinks.

Family-owned and never franchised. Spread across the western and southwestern US, slowly moving east.
