Appearing: Michael Voltaggio; Antonia Lofaso; Mei Lin Hua; and Nancy Silverton.

The final two chefs cook the meal of their lives in an effort to take home the ultimate title and prize; the chefs need to impress not only the judges but also culinary superstars Nancy Silverton, Jonathan Waxman and Curtis Duffy.

Actress Lena Waithe challenges the chefs to make a trademark Kentucky dish known as the Hot Brown; chef Nancy Silverton and butcher Dario Cecchini break down a whole cow for the chefs to utilize along with locally-sourced ingredients.

In the Quickfire, it’s a true test of communication as the chefs play a game of telephone with their loved ones as they try to reproduce the dish their family member is currently eating at a nearby restaurant. Then, the chefs are tasked with creating a signature product that they will bottle, use on a dish and sell at a food festival. They may get help from their visiting loved ones, but for one chef, the help won’t save them from being sent home. Celebrity Chef Nancy Silverton is the guest judge joining Tom, Padma and Gail.
