The Holiday Special brought back many of the ghosts of Top Chefs past as CJ, Marcel, Tre, Betty, Josie, Sandee, Stephen, and Tiffani came back to compete once more -- this time in Chicago. After opening some gifts and reminiscing, it was back to business. In the Quickfire the chefs were greeted by Padma and a mystery Santa, who turned out to be none other than the delicious Eric Ripert. The chefs had to create a dish from one gifted ingredient, which were chosen through a game of "Dirty Santa." For the Elimination Challenge, the chefs had to create a a three-course meal, and would be judged through every course head-to-head, meaning that two chefs would be eliminated each round.
