Top Chef

For the chefs' last quickfire challenge of the season, they're tasked with creating a classic Milanese dish and a feared dish, risotto; the chefs compete in a three-part, head-to-head culinary battle while receiving some help from Olympic athletes.

For their last elimination challenge, the final three chefs must create the best progressive four-course meal of their lives; with the help of their sous chefs, the finalists must pull out all the stops to impress an esteemed table of diners.

"Top Chef" heads to the Carolinas with 15 new chefs. For their first Quickfire Challenge, the chefs head to Charlotte Motor Speedway where they are greeted by Kristen, Tom and Gail, and the first guest judges of the season – NASCAR Hall of Famer Jimmie Johnson and two-time NASCAR cup series champion Kyle Busch. The chefs divide into teams of three and face a high-speed challenge as they prepare and plate their finest dish before the time it takes a professional driver to complete 23 laps. For the Elimination Challenge, the chefs will draw on their own culinary roots and create a dish featuring sweet potatoes, North Carolina's state vegetable. The judges are joined by Chef Sean Brock and "Top Chef" alum Jamie Lynch.

For this week's Quickfire Challenge, the chefs are tasked with creating a savory dish inspired by a sweet treat. Then the chefs head to PuckerButt Farms for a pepper tasting with Ed Currie, the inventor of the world's hottest pepper. For the Elimination Challenge, the chefs are split into two teams and must create a progressively hotter menu. "Top Chef" season 12 winner Mei Lin joins Kristen, Tom and Gail at the judges' table.
