Through to October 1, 2023 (or while supplies last), Jack In The Box is updating their signature Sourdough Jack sandwich with the addition of their new Double Sourdough Jack.
Featuring double the cheese and beef of the original, the new Double Sourdough Jack is served on 2 toasty pieces of sourdough bread with 2 all-beef patties, 2 strips of hickory-smoked bacon, a slice of American cheese and 2 slices of Swiss-style cheese.
This new Jack In The Box creation is then finished with ripe tomato, zesty ketchup and creamy mayonnaise.
