"It is absolutely fantastic to have someone of Raymond's calibre spearheading our drive to help the food industry wake up to the power of apprenticeships.
"From restaurants and bars to shops and suppliers, the capital's food industry is a booming trade that has huge potential to give thousands of young Londoners their first big break on the career ladder.
"With 100,000 apprenticeships now under our belt I believe this vibrant sector of our economy can play an increasingly important role in helping to swell that number even further."
Boris Johnson has teamed up with top chef Raymond Blanc to urge food and hospitality firms to take on more apprentices.
There are already 5,000 apprentices working in the capital's food industry - but the Mayor says there is huge potential to build on that.
Raymond Blanc is taking on 21 apprentices at Brasserie Blanc restaurants across London and the UK, working in a range of hospitality roles including as chefs and front of house staff.
"It is vital that the restaurant sector has homegrown talent to develop the necessary skill and craft for the future.
"I am self-taught and it was tough - I longed for a mentor to guide me through my career - so I am 100% behind the Mayor's drive to bring so many young people into the business and to give them the best chance to excel."
