Hosted by the inimitable Alton Brown and set in the newly renovated Kitchen Stadium, each standalone episode pits two up-and-coming chef competitors against each other, but only one earns the right to face a legendary Iron Chef and answer life's most savory question: "whose cuisine reigns supreme?" The Chairman (Mark Dacascos) and floor reporter Jaymee Sire join Alton as the culinary drama unfolds each week, with Iron Chefs Bobby Flay, Jose Garces, Alex Guarnaschelli, Michael Symon and newest member Stephanie Izard each taking on talented, determined challengers over the ten-episode season. Preceding Showdown's premiere is the one-hour special Iron Chef: Where Are They Now at 8pm, which explores the latest and greatest achievements of favorite Iron Chefs, followed by the debut of retrospective series Iron Chef: Behind the Battle at 10pm. Online, digital companion series Alton's Ingredient Alchemy rolls out simultaneously with a closer look at some of the latest Iron Chef secret ingredients.
