Jack in the Box’s Double Sourdough Jack features two grilled beef patties, double the hickory-smoked bacon, two slices of Swiss-style cheese, one slice of American cheese, tomato, mayo, and ketchup served on toasted sourdough bread.
Prices vary but the Double Sourdough Jack costs $7.99 near me (versus $6.69 for a regular Sourdough Jack). It’s also available as part of a combo with small fries and a small fountain drink for $10.99.
The Double Sourdough Jack is available now at Jack in the Box restaurants nationwide for a limited time through October 1, 2023.
