Irvine had hosted the show for four seasons. The network in March said it would revisit its decision not to renew his contract at the end of the season. Meanwhile, Food Network Iron Chef Michael Symon filled in for Irvine, taping 10 hour-long episodes.
"I am very excited to continue taping more episodes of 'Dinner: Impossible'," Irvine said in a written statement. "I am thrilled to further my relationship with the network and embark on more challenging episodes of this popular series."
New episodes starring Irvine will begin airing March 2009.
