Simon Young, executive chef at the Jumeirah Carlton Tower hotel, helped raise £105,000 for the Children's Liver Disease Foundation (CLDF) at the third Celebrity Chef Gala Dinner.
Forty of the UK's top chefs joined forces to cook for the bash on 22 March.
They were helped by aspiring chefs Jade Phillips (14) and Joshua Buckingham (13), who both suffer from liver disease.
Chefs Michael Caines from Gidleigh Park; Richard Corrigan from Lindsay House; Paul Gayler from The Lanesborough and James Martin presenter of BBC's Saturday Kitchen, each designed and prepared a course for the 350 guests.
Actress Linda Bellingham was on hand to cajole guests into parting with their cash in a raffle.
Jade said: "Although it was hard work I really enjoyed spending the day with Simon and his team. I got to meet Michael Caines and Paul Gayler and learnt lots of new skills."
Young added: "It was a delight to have Jade and Joshua helping us prepare for the fundraising dinner. Both helped to make what was a fantastic event even more memorable and I am sure with a lot of hard work both have what it takes to be talented chefs."
