Alexis Gauthier

In 2015, Gauthier changed his vegetable menu to be fully vegan. The 'Les Plantes' menu went on to win 'Best Vegan Menu' at the PETA Food Awards 2016. Gauthier became a vegan in 2016; he is now opposed to the "savagery" of meat, and "excited about a vegan future". He is transitioning his restaurants to be fully plant-based.

During the Bird Flu pandemic in 2005, Gauthier removed chicken, pigeon and foie gras from the menu at Roussillon after he noticed a drop in demand. Gauthier left Roussillon in 2010 to set up a new restaurant called Gauthier Soho; he had been looking for a new location to open his own restaurant as he wanted to move away from his two business partners. Gauthier kept his share of the ownership of Roussillon. Because of this, Roussillon lost its Michelin star and went on to go through two chefs before finally closing on 1 June 2012. After it closed, Gauthier stated to the industry press that he hoped to be able to buy back the location.

In 2011, whilst dining at the restaurant DuckSoup, Gauthier was seated at a table near to food critics Matthew Norman from The Daily Telegraph and Tracey MacLeod from The Independent. MacLeod had previously given Gauthier Soho a critical review, while Norman had given the restaurant the best review it had received in Gauthier's opinion. Whilst sitting there, Gauthier tweeted the actions of the food critics to his followers and criticised them on several points such as their loudness, a copy of The Independent sitting facing out in an open bag by MacLeod's feet and that Norman didn't know what aioli was. Gauthier later said that it was "nothing personal", and the critics took it in good spirits with Norman saying, "I am extremely loud in restaurants because I am a little hard of hearing, my wife is thrilled that this has finally been independently confirmed."

Gauthier was diagnosed in October 2010 with a fatty liver, which resulted in him cutting down his calorie intake and listing calorie counts on his menu at Gauthier Soho.

He appeared with Gregg Wallace and Michel Roux Jr. as a judge on BBC One's MasterChef: The Professionals in October 2009. He later also appeared on the regular MasterChef series, once more alongside Wallace, and also with John Torode in March 2011 and March 2019.

In 1991 he started working in a restaurant for the first time, at the Hotel Negresco in Nice, France. He moved to work under Alain Ducasse at his Le Louis XV restaurant in Monaco between 1993 and 1996. He left Ducasse's employment to go to Roussillon in Pimlico, London, which opened in 1998 with Gauthier as head chef. The restaurant had previously been known as Marabel's, but was relaunched upon Gauthier's arrival. In 2000, it was awarded a Michelin star. It was also awarded three AA Rosettes, and won the Time Out "Best Vegetarian Award" in both 2000 and 2001.
