Allergens from the Burger King allergen chart (June 2025) entry "IMPOSSIBLE Whopper Sandwich".
Burger King says its allergen information is based on suppliers' ingredient lists and that shared cooking and preparation areas and utensils mean any item can come into contact with other allergens. Fish, pork sausage, chicken items, hash browns, mozzarella fries, French toast sticks and onion rings share fryers, and burger buns, sandwich buns and croissants share a toaster; the frying oil is a corn, canola, soy and/or cottonseed blend. The Impossible patty is cooked on the same grill as beef, and Burger King makes no vegan or vegetarian claim for it. Its allergen chart reflects supplier ingredient lists as of June 2025 and may leave out test and limited-time items, and guests with allergies are told to check bk.com before ordering.
