A Kansas City-style hot dog is served in what kind of seed bun?

A Kansas City-style hot dog is served in a sesame seed bun.

The Kansas City style is generally described as a pork sausage placed in a sesame seed bun and topped with brown mustard, sauerkraut, and melted Swiss cheese. The combination gives the style a distinctive balance of smoky meat, tangy cabbage, sharp mustard, and creamy cheese.

The sesame bun is an important identifying detail because regional hot-dog styles often differ in their bread as well as their toppings. Chicago-style hot dogs, for example, are associated with poppy seed buns, which is the most likely source of confusion in this question. A sunflower seed bun is not the standard Kansas City marker, and caraway seed is more closely associated with certain rye breads and European flavor profiles.

Regional descriptions can vary by restaurant, but the sesame seed bun is the conventional answer in reference works. The style is also sometimes discussed alongside Kansas City’s broader barbecue and sausage traditions, though it should not be confused with a generic barbecue sausage sandwich.
