Masterchef (UK) is een Brits competitieprogramma van de zender BBC One. De serie ging in première op 21 februari 2005.
12 hobbykoks gingen de ultieme kookstrijd met elkaar aan en kregen de meest onmogelijke opdrachten voor hun kiezen, waarbij ze werden beoordeeld door de onverbiddelijke jury bestaande uit Peter Lute en Alain Caron.
It's the MasterChef final. After a formidable seven-week competition, the search for the country's best amateur cook reaches its climax. The finalists have to push themselves to the limit for one last time before Judges John Torode and Gregg Wallace crown one of the three highly talented amateur cooks the champion. This is their final chance to pull out all the stops, show everything they have learned, and in three hours demonstrate what sort of cook they have become. They must produce three exceptional courses, push their culinary boundaries and give the judges an awe-inspiring tasting like never before. It's a night packed with culinary highlights, as one of these three exceptional amateur cooks lifts the trophy and becomes the 11th MasterChef Champion.
