The chefs return to Los Angeles to celebrate the series' 10th anniversary. A restrictive challenge limits them to 10 ingredients, then they walk down memory lane by creating a dish that represents who they were 10 years ago. Appearing: Michael Voltaggio; Antonia Lofaso; Mei Lin Hua; and Nancy Silverton.

A blindfolded taste experiment tests the chefs. Later, the chefs draw inspiration from their own childhood memories to create meals for a charity gala for the MUSC Shawn Jenkins Children's Hospital. Appearing: Michael Voltaggio and Graham Elliot.

The Voltaggio brothers reunite on the show for the first time since competing against each other. Their first task is judging the Rocky Mountain Oyster Quickfire. Then, they reunite the chefs with surprise visitors from home in an emotionally charged Elimination Challenge, where one chef will pack their knives before the next leg of the finals in Aspen.
