Percentages are the share of the FDA Daily Value for adults and children 4 and over, worked out from Panera Bread’s published amounts (how % Daily Value works). A dash means Panera Bread does not publish that value for this size. Not published for this item: added sugars.
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, the Cup size is high in sodium (53%) and saturated fat (25%) and is low in dietary fiber. Add it up with other items in the Panera Bread nutrition calculator.

Allergen information is for the soup; the bread bowl variant also includes the Sourdough Bread Bowl (see Breads).
Panera's allergen guide covers its national menu and marks each item as containing or possibly containing wheat (a column that also flags other gluten sources), tree nuts, peanuts, milk, soy, egg, fish/shellfish and sesame. Panera reports fish and crustacean shellfish together in one column without saying which, so an item marked there is listed here under both. Highly refined oils from allergenic sources are not counted, following the FDA. Many products can come into contact with common allergens during production and in the cafe, where equipment is shared, so Panera cannot guarantee any item is allergen-free. Sandwich information assumes the default bread; changing the bread or customizing can add allergens, and online customization does not update allergen information. Menus vary by location, so guests with allergies should ask a cafe manager to check the ingredient listing.
