Henry Harris, who oversaw the food at Knightsbridge restaurant Racine until last year, will take over the kitchen team at recently reopened site the Dog & Badger in Medenham, at the end of this month.
Harris said: "I was fortunate to be involved in the Dog & Badger's inception, helping with the concept and design – so, naturally, I am delighted to be taking up the reins here."
He added: "I'm looking forward to bringing a touch of French bourgeois cuisine to the countryside of Buckinghamshire."
Sample dishes Harris has planned for the pub include duck confit with lentils; British hake with asparagus and beurre blanc; Dorset lobster with garlic butter; and Côte de Boeuf.
Meat and game will be sourced from local farms and some produce will be home-grown in the pub's cottage gardens.
The Dog & Badger has also recently completed work on six rooms, converted from a neighbouring Grade II-listed cottage.
Harris is the latest in a series of high-profile chefs to enter the pub trade this year.
Claude Bosi, owner of double Michelin-starred restaurant Hibiscus, in Mayfair, announced last week the opening of his new pub the Swan, in Esher, Surrey.
And Stephen Ellis, who previously worked at Gordon Ramsay's eponymous triple Michelin-starred eatery on Royal Hospital Road, Chelsea, announced the upcoming opening of his Berkshire gastropub the Oxford Blue.
