MasterChef is a BBC television competitive cooking show. It initially ran from 1990 to 2001 and was later revived in a different format known as MasterChef Goes Large from 2005 onwards. In 2008, the "Goes Large" part of the name was dropped, but the format remains identical. The revamped format was devised by Franc Roddam and John Silver with Karen Ross producing. The series now appears in four versions: the main MasterChef series, MasterChef: The Professionals for working chefs, Celebrity MasterChef, and Junior MasterChef, for 9-to-12-year-olds. The format has been reproduced around the world in a large number of international versions.

Junior MasterChef is a British TV cookery competition, broadcast by the BBC, in which nine- to twelve-year-olds compete to be crowned Junior MasterChef. It is a spin-off from the main series MasterChef. Junior MasterChef first ran from 1994 to 1999, presented by Loyd Grossman. After a long hiatus, it was revived in 2010 in a revamped format, presented by writer and actress Nadia Sawalha, previously a Celebrity MasterChef contestant and restaurant owner, and professional chef John Torode, who also presents MasterChef. The revival series was commissioned by CBBC Controller Anne Gilchrist and produced by Shine Television, and was broadcast on BBC One. A further series was commissioned in 2012 for broadcast on CBBC.
