The remaining chefs leave the pantry behind to harvest the ingredients that will decide their fate and then return to the Penthouse to face the Sustainability Commandment. Their challenge: transform farm‑fresh produce alongside hyper‑sustainable ingredients like ants and mussels into bold, elevated dishes. When the scores are tallied, the bottom two chefs are pushed into a ruthless head‑to‑head, cooking one final time using only discarded scraps and leftovers.

The remaining chefs face off in teams of three to deliver a vegetarian three-course menu to a dinner party of elite guests from the culinary world. The catch? Each chef must stay within the parameters of their vegetable family, with one lucky chef creating an all-vegetable dessert. After plates are cleared and scores tallied, the bottom team must turn against each other in a three way showdown where one chef is sent home.
