I was born in Belfast and grew up in Co. Antrim in Ireland. In 1985 I graduated in Modern Languages from The University of Edinburgh and then moved to my food paradise, France. For over thirty years I lived in and around Paris, raising four children - three sons, two of whom are now chefs, and a daughter.


After working in fashion, marketing and PR in Paris, in 1999, I created a mail order company selling high quality chocolate and professional cooking equipment, just as pop culture started embracing food, showing it in an infinitely more glamorous and exciting light than in the past.


In 2000, I was approached by French publishers Hachette to write my first cookbook “Petits Plats entre Amis” . It was a hit.  It turned out that relaxed food and pared back styling was just what French home cooks - wearied by the pressure of centuries of chefs’ regimented approach in the kitchen - were after.  Since then, my unabashed love of eating and cooking, with a penchant for chocolate , has kept me busy writing about food. 


I have now published 35 books in English and French, including several co-editions for the US and UK markets, which have been widely translated, with ‘Je Veux du Chocolat’ selling hundreds of thousands of copies around the world. My books include commissions for La Grande Épicerie de Paris, Picard France and Marks and Spencer France. 


In 2013 I published 'The Paris Gourmet' for Flammarion in English and French, a guide to Parisian restaurants, markets and shops, another of my Gourmand Award Winners and a fun departure from cookery. It was translated into seven languages.   


My books have won 5 World Gourmand Awards,  Le Prix Laduree, le Prix de la Nuit du Livre, Le Prix Hédiard, le Prix la Mazille and le Prix des Savoureuses in 2018 for ‘C'est de la Trish’ at the Périgueux Cookbook Fair. In 2016, ‘Home Recipes from Ireland’ was shortlisted for an Irish Book Award. 


In 2009 I was named one of French GQ and Vogue’s 40 Women of the decade.  They said, « There is a before and after Trish Deseine in the culinary world. Thanks to her, cookbooks became beautiful, from the cover to the recipes and writing. You want it all. Old dishes are revisited, become festive and easy to do. Today, hers is one of the most rich and attractive collections in culinary publishing. » 


In November 2020, my latest book, ‘My Comfort Food’ (Editions de La Martinière) was awarded the Grand Prix Eugénie Brazier for food writing and Le Fooding, the cult French food and restaurant guide, branded me, “pop culinary icon of the 2000s and non-stop bestselling author.”


I have presented three RTE TV cookery series, broadcast by BBC Lifestyle worldwide, and two recent productions with BBCNI. I'm currently The Gloss Magazine Ireland's food writer, and have written for, reviewed in and contributed to  ELLE and ELLE à Table France, Image Ireland, Le Fooding, Wallpaper Guides, The GuardianThe Gloss features,  The Observer Food Monthly  The Financial Times,  The Sunday Times  and The Irish Times. Here's a BBC Radio 4 Food Programme Sheila Dillon made about me where we talk about my life in France and return to Ireland in 2015. 


After three years in the little food paradise of west Cork, Ireland, I'm now living in a tiny country village in la Sarthe, near the beautiful Perche town of Bellême. 

My three latest books were published by Les Editions de la Martinière, Paris. 'C'est de la Trish', all about condiments and other taste boosters, was published in 2018. 'Un Soupçon de Sucre'  (October 2019) dives into baking with flavoursome, unrefined sugars. ‘My Comfort Food’ came out in autumn 2020. 

My new book "La Cuisine Veggie et Vegane par Une Omnivore Réticente mais Amoureuse", is all about how non vegetarian and vegan cooks can please everyone around their table, whatever their régime.
