Using the FDA’s rule of thumb that 5% of the Daily Value or less per serving is low and 20% or more is high, one serving is high in cholesterol (172%), saturated fat (80%), sodium (70%), protein (70%) and fat (59%). Add it up with other items in the Jack in the Box nutrition calculator.

SesameUnclear: see note

Jack in the Box’s two official files disagree: the nutrition guide marks sesame for this item, the allergen guide does not. Treat it as possibly present.

Buns contain sesame in some regions.

Jack in the Box kitchens handle soy, egg, fish, milk, wheat and sesame, and shared equipment means an item can pick up one of these even when its ingredients do not list it. Grilled vegetables, eggs and some bakery items are cooked with a butter-flavored vegetable oil that adds soy. The allergen guide does not cover dressings, crunchy toppings, dipping sauces or sauce packets within other items; those are listed on their own. Guests with food allergies are advised to consult their physician and to recheck the information often, since menus and ingredients change.
