Fox has renewed Gordon Ramsay's "MasterChef" cooking competition series for a tenth season. "MasterChef" Season 10 will air sometime during the 2018-2019 television season. A nationwide casting call has begun and will continue throughout September as the series searches for its next group of cooks who will compete on the show. The renewal came ahead of the show's Season 9 finale on Wednesday, when Louisville native Gerron Hurt earned the MasterChef title and the $250,000 grand prize. "MasterChef" is the most-watched cooking program in the United States, with Season 9 averaging 6.4 million viewers, noted The Hollywood Reporter. Ramsay also helms a number of other cooking-based shows for Fox such as "MasterChef Junior," "Hell's Kitchen" and "24 Hours to Hell and Back."
