Murchison started his kitchen career as a
kitchen porter, aged 14. Like most chefs, he worked in a number of restaurants, learning and promoting along the way. He had stints in
Claridges,
Inverlochy Castle,
Le Manoir aux Quat'Saisons,
L'Ortolan and
Nobu. In 1999, he became director of the cookery school of Le Manoir aux Quat'Saisons. Murchison returned to L'Ortolan in 2001 this time as
head chef. In 2003, the restaurant was awarded a
Michelin star. Two years later he left to take up a position as executive head chef at
Chewton Glen hotel in
New Milton, Hampshire. He left three months later. After a few minor consultancy jobs, Murchison rejoined L'ortolan in September 2004, this time as director-executive head chef with an option to buy the restaurant. In 2007, Murchison jumped on the opportunity to buy the former
Hibiscus restaurant in
Ludlow, Shropshire from
Claude Bosi. He reopened the place as
La Bécasse. Later, Murchison founded "Alan Murchison Restaurants Ltd.", later restyled as the
10 in 8 Fine Dining Group. The general idea behind it was: The group now includes four restaurants and a cookery school. Alan Murchison acquired
Paris House in late 2009. The
Woburn, Bedfordshire-based restaurant was bought out of the legacy of
Peter Chandler, who died earlier in 2009. Murchison also acted as mentor for the Nestlé
Toque d'Or student catering competition 2010. In Murchison's opinion it is "to give something back, having benefited from strong mentorship early in his career". In 2010, Murchison added the
New Angel restaurant to his "10 in 8 Fine Dining Group". He had the plan to reopen is with its original name
Carved Angels, but found out that was impossible due to trademark issues. At the end, the restaurant reopened as
Angélique. Murchison appeared on a BBC series
Great British Menu. He lost to
Tom Kitchin in 2009 in the Scotland heats. He won the Scotland heats in 2010 and 2012 but did not win the finals. In 2011, Murchison reappeared on
Great British Menu once as a judge for the Scottish heats. In November 2013, Alan Murchison Restaurants was
liquidated, leaving more than fifty creditors with unpaid amount of owed by the group. In 2014, Paris House and 10 in 8 also fell into liquidation. Later that same year, Murchison resigned as executive chef of L'Ortolan. ==Plant-based diet==
