Co-operative Food magazine, published by River, will have a print run of one million.
It will be available for free in all Co-operative food stores and other Co-operative societies including Midcounties, Midlands and Anglia Regional.
The magazine will carry advertising from suppliers and a digital version will be available to view on The Co-operative Food website.
Content will include simple meal ideas for convenience cooks or more complex meals for more experienced cooks and will support the brand's 'Good With Food' positioning and reinforce its value messaging.
Helen Nunn, head of marketing at The Co-operative Food, said: "The Co-operative Food magazine is a key element of our brand marketing programme to highlight our value proposition focused on delivering 'Big Deals Within Easy Reach'.
"In-store magazines are proven to drive sales and our multi-channel approach will ensure maximum reach for our content by allowing us to communicate with our customers on a number of different levels."
River won the account after a competitive pitch and will handle both the print and online version of the magazine as The Co-operative attempts to capitalise on the public's increasing use of mobile to consume content.
