Pippa Middleton said she was "delighted" to become a columnist for Waitrose's monthly magazine.
The Duchess of Cambridge's sister will pen a column called Pippa's Friday Night Feasts which will feature "casual dining ideas and recipes".
The first column will appear in the April edition, with Pippa featuring on the front cover.
Miss Middleton said: "I'm delighted to be writing for Waitrose Kitchen, a magazine that's always been a source of inspiration to me, for its extensive spectrum of food and beautiful style.
"My column, 'Pippa's Friday Night Feasts' will be an exciting opportunity to share my own passion and enthusiasm for food and entertaining and I can't wait to get started."
