The MasterChef kitchen welcomes 12 emerging home cooks and 12 of MasterChef's most loved past contestants. Together they will share their love of food and compete to become Australia's next MasterChef.

Bonjour! Get ready for tonight's classic service challenge with guest chef Shannon Bennett. Each team must cook a French inspired entree, main and dessert for 20 diners plus the judges.

The winning team in yesterday's relay challenge join the top two mystery box winners for a chance at immunity as they try to Beat The Chef, who just happens to be MasterChef favourite Matt Stone.

The bottom two teams from yesterday's challenge face elimination and must split their 90 minute cooking time over two rounds, with the creator of the least impressive second round dish going home.

Contestants must create a dish using the same ingredients that were in the very first mystery box in MasterChef season one, The least impressive fare will send their chefs to a pressure test cook-off.

Guest chef Shannon Bennett returns with 10 of his favourite fridge and pantry items to create today's mystery box. The two least impressive cooks will face off in tomorrow's pressure test.
