The Sourdough Jack is a signature Jack in the Box cheeseburger consisting of a beef patty topped with bacon, tomato, Swiss-style cheese, Mayo-Onion sauce, and ketchup on toasted sourdough bread. It has been compared to a patty melt.
The sandwich was originally released as the "Grilled Sourdough Burger" in 1993, with the name changed to "Sourdough Jack" in 1997.
In 2000, a Beaverton, Oregon couple sued Jack in the Box for $7 million after allegedly finding staples and hair in their Sourdough Jacks.
"Sourdough Jack" is also the name of a cartoon character used since 1952 by the Fairbanks Daily News-Miner, an Alaskan newspaper.
