Zahn was born in Marshall, Minnesota, the son of Zelda, who worked for the YMCA, and Carleton Zahn, a retired Missouri Synod Lutheran pastor. Zahn spent part of his childhood in Mankato, Minnesota, attending Kennedy Elementary School, and later moved to the suburbs of Minneapolis. After attending Robbinsdale Cooper High School, Gustavus Adolphus College, and the Institute for Advanced Theatre Training at American Repertory Theater at Harvard University, his first professional acting role was in Biloxi Blues, a Minnesota production at the Old Log Theater; but his first big break came in 1994, when he was noticed by Ben Stiller, who cast him in his picture, Reality Bites.
Zahn's early roles were split between movies, touring companies of Broadway shows, and TV shows. In 1992-1993, he toured as Hugo with the Barry Weissler production of Bye Bye Birdie with Tommy Tune, Ann Reinking, and Marc Kudisch. He played Phoebe Buffay's husband Duncan in a 1995 episode of Friends. Zahn appeared in several films in the mid-1990s, including Tom Hanks' That Thing You Do! These films garnered him enough respect that he was offered the starring role in the critically acclaimed indie film Happy, Texas (1999). Some of Zahn's most popular movies have been his later ones, including National Security (2003), Daddy Day Care (2003), and Sahara (2005). In Sahara Zahn starred alongside Matthew McConaughey. Zahn received his strongest critical acclaim for his performance in Riding in Cars with Boys, in which he co-starred with Drew Barrymore as her dim-witted, drug addicted husband. Roger Ebert, Richard Roeper and the BBC stated that the performance was deserving of an Oscar nomination. He also voiced Runt of the Litter in Chicken Little . He also gave dramatic performances in Rescue Dawn and the television mini-series Comanche Moon.
Typically typecast into comic relief sidekick roles, Zahn was asked if he minded, his reply was that it was a "pleasure" and a "privilege", saying: "to be typecast and make money and make people happy and people dig what you do, what a great thing, man."
Zahn stars as Davis McAlary in Treme. Davis is a New Orleans native, and local music lover, as well as one of Treme's biggest partiers, and advocates. Zahn also recorded a song for the show, and is featured on the show's soundtrack. The track, "Shame, Shame, Shame", criticizes George W. Bush and the American government's response to the disastrous aftermath of Hurricane Katrina in New Orleans.
Zahn is married to Robyn Peterman, an actress whom Zahn met on a touring production of Bye Bye Birdie. Zahn is also a faithful University of Kentucky sports fan, often seen at games and events.
