16 celebrities will be putting their palates to the test and proving their culinary worth on primetime BBC One.
Sugababes star Heidi Range, comic Les Dennis, actors John Thomson, Denise Black and Brian Capron, and Bottom star Ade Edmondson are among the competitors.
Katy Brand, Shappi Khorsandi, TV presenter Miranda Krestovnikoff and sports stars Phillips Idowu, Matthew Hoggard and Joe Calzaghe are also taking part.
Completing the lineup are Jo Wood, rapper Speech Debelle, Boyzone's Shane Lynch and broadcaster Janet Street-Porter.
Exec producer Carla-Maria Lawson said: "The return of Celebrity MasterChef to this BBC One peak time slot sees thrills and spills and some extraordinary cooking from our lineup of well-known faces.
"In this series, the contestants' enthusiasm in their pursuit of the MasterChef trophy is palpable, often inspiring and sometimes very, very funny."
Airing across six weeks, the show's challenges will include mass catering for Cirque du Soleil and the Harlequins rugby team, cooking for former Celebrity MasterChef stars Lisa Faulkner, Phil Vickery and Andi Peters, and dishing up meals for the dreaded restaurant critics.
