Fifteen Cornwall opened in May 2006 and with more than 100 apprentices graduating since.
Around 80 per cent of those who passed out from the chef academy are still in the kitchen today.
However, while the restaurant is keen to discuss its successes – there have also been many stories that end in tragedy.
One of Jamie Oliver’s first Fifteen apprentices was Kevin Boyle, a 26-year-old Crystal Palace supporter from Purley, Surrey.
A keen and talented chef, he worked for Vinoteca restaurant in London and cooked for the Prince of Wales and former Prime Minister, Tony Blair, after finishing Oliver’s scheme.
But in October 2011, the Lancaster University graduate, then 26, was reported missing from his home. In January 2012, he was found dead in a garden in nearby Coulsdon, and his mother, Patti, 54, said he had committed suicide with a kit he had bought for £44 over the internet.
At the time, Oliver said: ‘I’m deeply saddened by this tragic news. I am proud to have been able to call Kevin a friend for ten years.’
It was the second tragic death to hit the chef’s trainee scheme.
In 2008, Christopher Pethick, 20, was found hanged a few miles from the Fifteen restaurant in Watergate Bay, Cornwall.
He dropped out of the course in 2006 after two months with severe depression.
Crime has touched the Fifteen trainee scheme, too.
In 2009, a former apprentice on Jamie Oliver’s Fifteen scheme was sent to prison after admitting taking part in a £3million jewellery heist in Southend Airport.
Former drug addict Tom Baisden, then 28, from Thundersley, Essex, admitted theft, conspiracy to steal, and conspiracy to pervert the course of justice by plotting to steal gems, Cartier watches and designer handbags.
He told the court he was inspired by his celebrity chef mentor to confess to his crimes, after Oliver told him: ‘You can’t run away from things or hide from them.’
While in October that year Christopher Murray, 21, was jailed for sexually assaulting two women on the London Underground.
Murray, who trained as a fishmonger before joining Fifteen, was sentenced to two years after he admitted the offences at Southwark Crown Court.
