Sourdough Jack

  • Signature

The best burger Jack in the Box makes, and it is not on a bun. A beef patty with bacon, Swiss and American cheese, tomato, mayo and ketchup is pressed between slices of grilled sourdough, so it eats like a burger crossed with a grilled cheese. The tang of the sourdough is the secret. It has been on the menu since the late 1990s, and fans get genuinely upset when it disappears.
