The chefs expand their horizons in a master class on Nigerian flavors guided by local chef Ope Amosu, and all-star Kwame Onwuachi. They'll have to pay close attention because for this Quickfire challenge they must create a stew that perfectly pairs with traditional Nigerian swallows. Then, "Top Chef Colorado" winner (and part-time paleontologist) Joe Flamm challenges the chefs to dig deep and dominate the competition. They'll work in teams of three to create a progressive menu of jurassic proportions to serve the judges, as well as a special guest from the upcoming film "Jurassic World Dominion."

As the chefs return to the Top Chef Kitchen they are greeted by a rainbow of produce and all-star Nyesha Arrington, who asks them to create a monochromatic plant-based dish for their Quickfire Challenge. Then, for the Elimination Challenge, the chefs will be tasked with creating dishes that speak to their souls for a block party fundraiser. To gain inspiration they'll visit historic Freedmen's Town where they'll meet with Zion Escobar from the Houston Freedmen's Town Conservancy. The chef's will have to bare their souls in the historic Bethel Church to feed 120 diners as well as guest judges Dawn Burrell and Kwame Onwuachi, who know a thing or two about cooking from the heart.
