Michel Roux Jr will present the first programme after Martin's departure on April 2nd, while Rick Stein, Masterchef judge John Torode and Lorraine Pascale are among the famous names set to take the helm over the next few weeks.
Chinese food specialist Ching-He Huang, Italian restaurateur Gennaro Contaldo and British chef Matt Tebbutt have also been confirmed as guest presenters.
Roux Jr said: "I've been a fan of the show for many years and can't wait to cook up some magic with some of the great chefs the show attracts."
Pascale added: "I am so excited to be hosting Saturday Kitchen. I will miss sitting at home on the sofa in my pyjamas watching James Martin but so happy to be a part of the next chapter of this quintessential show."
Meanwhile, Torode said he was "really excited to be part of the new Saturday Kitchen family".
Martin will present his last Saturday Kitchen on BBC One on March 26 after 10 years with the show.
The live cookery programme has become a hit with viewers since its inception in 2002, fronted by a then relatively unknown Gregg Wallace, followed by Antony Worrall Thompson.
A BBC spokeswoman said Martin's last show would be "packed with plenty of nostalgia, classic clips from James's tenure, and surprise appearances by some of the big name chefs who have made his 10 years so memorable".
Martin has not disappeared from the show entirely and will still be seen on Saturday Kitchen Best Bites on BBC Two on Sunday mornings.
