Clare Smyth was born on September 6, 1978, in Belfast and grew up on a farm in County Antrim, Northern Ireland, the youngest of three children of her father William, a farmer, and her mother Doreen, who worked as a waitress at a local restaurant. Her early exposure to food and farm life, combined with holiday work in a local restaurant kitchen as a teenager, set the direction for her career. She left school and Northern Ireland at 16 to pursue professional kitchen work in England, later studying catering at Highbury College in Portsmouth, according to Wikipedia.

Smyth’s early training included an apprenticeship at Grayshott Hall in Surrey and stints at Terence Conran’s Michelin House restaurant Bibendum, The Fat Duck, and the Waterside Inn, before winning Young Cornish Fish Chef of the Year while working at the St Enodoc Hotel in Cornwall. She joined Gordon Ramsay’s team at his eponymous Chelsea restaurant in 2002 and rose to senior sous chef within three years, according to a profile from the National Restaurant Awards. During this period she also gained international experience through stages at Thomas Keller’s The French Laundry and Per Se in the United States, and at Alain Ducasse’s Le Louis XV in Monaco, exposure that shaped the classical French technique underpinning her later cooking.

In 2007, Smyth was named head chef at Restaurant Gordon Ramsay on Royal Hospital Road, becoming the first female chef in the United Kingdom to run a three Michelin star restaurant, a title she held while serving as chef patron for several years afterward. She spent a total of around 13 years working alongside Gordon Ramsay before leaving the Ramsay Group in 2016 to open her own restaurant, with Ramsay publicly backing her new venture at the time, as reported by The Caterer. That move led directly to the opening of Core by Clare Smyth in Notting Hill, London, in 2017.

Smyth was appointed MBE in 2013 for services to the hospitality industry and named the Good Food Guide’s National Chef of the Year the same year, later becoming the first female chef to receive a perfect 10 out of 10 score from the guide, per Wikipedia. In 2018, she was named World’s Best Female Chef by The World’s 50 Best Restaurants organization, a recognition she has described as a platform to push for greater gender balance in professional kitchens, as detailed in a World’s 50 Best interview. Core was awarded two Michelin stars in 2019 and a third in 2021, making Smyth the first British woman to hold three Michelin stars for a restaurant of her own, and in 2022 her Sydney restaurant Oncore earned three hats in the Australian Good Food Guide, making her the first female chef to hold three Michelin stars and three hats simultaneously.

Core has featured on The World’s 50 Best Restaurants extended list, ranking at number 97 in the 2024 edition, according to the organization’s own establishment listing. Smyth is a regular presence in British food media, having appeared on MasterChef, Saturday Kitchen, Great British Menu, and The Final Table, and she is frequently cited in industry coverage as one of the most influential chefs to come out of the UK fine dining scene in the last two decades.

Smyth has built a portfolio of luxury brand partnerships that run alongside her restaurant work. Her relationship with watchmaker Hublot has been described by industry press as an unusually authentic pairing, built around a shared rejection of stuffy formality between Core’s approach to fine dining and Hublot’s approach to watch design, according to Time and Tide Watches. She is also reported to serve as an ambassador for champagne house Dom Pérignon, cookware brand HexClad, and kitchen appliance maker Gaggenau, according to Wikipedia, extending her commercial reach well beyond the restaurant floor.

Since leaving the Gordon Ramsay Group, Smyth has built a small but high-profile group of ventures. Core by Clare Smyth in Notting Hill, opened in 2017, remains her flagship. Oncore by Clare Smyth, her first restaurant outside the UK, opened at Crown Sydney in November 2021, though the restaurant’s final service is scheduled for February 28, 2026, with the closure attributed to the expiry of its lease at the Crown Sydney site, according to Broadsheet Sydney. In 2025, she opened a new, more casual venture called Corenucopia in Chelsea, London, as reported by The Caterer. In 2024, she also launched a premium kitchen knife brand, Cutler & Smyth, made in partnership with British cutlers using Sheffield-produced steel, per the brand’s official site.

Smyth’s most significant identifiable assets are her restaurant businesses rather than a publicized personal real estate portfolio. Unlike many celebrities, she has not made her personal property holdings a matter of public record, and no outlet has published verified details of a home portfolio. Wikipedia’s biography notes that she resides in Wandsworth, London, with her husband Grant, who works in finance, but does not detail the property itself, per Wikipedia. Her major tangible business assets are her ownership stake in Core and its Notting Hill premises, alongside her interests in Corenucopia and the knife brand Cutler & Smyth.
