The Cooking Channel show, which saw the premier of its second season Wednesday, will include an episode alongside Gosselaar.
Thiessen says Gosselaar is the "most anticipated guest" on the show this season, according to Vanity Fair. "Everybody wanted him on," she said.
Although they played a romantic storyline in the early 1990s show Saved By The Bell, Thiessen says there will not be any flirtatious behavior during Gosselaar's episode.
"He comes with his beautiful wife and it's kind of a double date between myself and my husband and [Mark] and his wife," she added.
