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.
The pressure is mounting as the country's best five amateurs enter the seventh week of the cooking competition of their lives. John Torode and Gregg Wallace set the contestants the challenge of cooking for three leading restaurant critics. The five have to pull out all the stops as they make their own finest three courses and try to impress the hyper-critically honed palates of their guests: Charles Campion, Tracey MacLeod and Jay Rayner. With one contestant due to leave at the end of the show, the pressure is intense in the MasterChef kitchen as timings go awry, emotions take over, and dishes either explode with flavour or crash and burn.
