What seasoned salt is added to a Chicago-style hot dog?

The seasoned salt added to a Chicago-style hot dog is celery salt.

Celery salt is sprinkled over the finished Chicago dog alongside its signature toppings: yellow mustard, chopped onion, sweet pickle relish, tomato, a dill-pickle spear and pickled sport peppers. It contributes a savory, lightly vegetal note that helps balance the sweetness of the relish and the acidity of the pickles and peppers.

The seasoning is part of what separates the canonical Chicago style from a generic loaded hot dog. The usual base is an all-beef frankfurter in a steamed poppy-seed bun, and the traditional recipe avoids ketchup. Celery salt is generally added as a finishing dash rather than mixed into the sausage itself.

A frequent mistake is to call it simply “seasoned salt,” which is a broader category of seasoning blends. Onion salt and garlic salt can flavor other foods, but neither is the named traditional garnish for a Chicago-style hot dog. Some vendors make substitutions or omit it, but celery salt remains the standard answer.
