Panera ingredients & allergens

Read the full recipe for your chosen size.

358 exact product variants with nested ingredient declarations. Default recipes, bread and sauces remain part of the product identity.

Customisation can change the allergen profile.

Panera’s ordering interface does not reliably revise allergen statements when ingredients change. These declarations describe the exact default recipe, with contains and may-contain fields kept separate. Shared equipment and substitutions can affect the order you receive.
