The Sourdough Jack is a signature Jack in the Box cheeseburger consisting of a beef patty topped with bacon, tomato, Swiss-style cheese, mayonnaise, and ketchup on toasted sourdough bread.[1]

The Sourdough Jack has been compared to a patty melt.[2] A Jack in the Box spokesperson once called it "an adult spin on the more traditional hamburger."[3]

The burger was originally released as the "Grilled Sourdough Burger" in 1989, with the name changed to "Sourdough Jack" in 1997.[4] It previously used Mayo-Onion sauce instead of mayonnaise.[5]

In March 2021, the official Jack Box Twitter account announced the Sourdough Jack would be discontinued, but it was only an April Fools Day joke.[6][7]

Miscellaneous[]

"Sourdough Jack" is also the name of a cartoon character used since 1952 by the Fairbanks Daily News-Miner, an Alaskan newspaper.[10]
