The Season 18 premiere: Chef Gordon Ramsay invites eight previous contestants back to the kitchen to battle against eight ambitious rookies for a chance at a life-changing grand prize: an Executive Chef position at the world’s first Gordon Ramsay Hell’s Kitchen Restaurant at Caesars Palace Las Vegas. In the first challenge, the rookie chefs will cook up the best versions of their signature dishes within 45 minutes, while the veterans will attempt to create the same dishes.
