Home cooks and Julia Child superfans compete during two rounds of competition in an attempt to impress the judges with their culinary abilities and share how Julia changed their lives. The first round masters the basics and challenges the competitors to re-create one of Julia's signature dishes, with some guidance from Julia herself, as seen on a giant television screen in the middle of the action. Round 2 is an ode to Julia, where competitors must take inspiration from Julia to create a unique dish reflecting their own culinary point of view. Dishes from the second round are served family-style, with competitors and judges sampling each dish and sharing stories about their food journeys and personal connection to Julia. Antonia Lofaso and a rotating panel of guest judges will decide which of the competitors wins the life-changing grand prize that literally follows in Julia's footsteps: an all-expense paid three-month cooking course at Le Cordon Bleu.

Over forty trainees have graduated from Fifteen. Now it's time for Jamie Oliver to cut the apron strings and see who has what it takes to open and run their own gastro-pub. A mass cook-off leaves Jamie with four potential candidates, and a series of challenges resulting in a final pitch will reveal who gets their hands on the keys to an Essex pub. Then the real hard work begins. Jamie's biggest challenge will be letting his protégé get on with it, without getting stuck in himself.

Amateur chefs compete against each other by hosting a dinner party for the other contestants. Each competitor then rates the host's performance with the winner winning a £1,000 cash prize. An element of comedy is added to the show through comedian Dave Lamb, who provides a dry and "bitingly sarcastic" narration.
