Soon after graduating, McCarrell began acting professionally in regional productions of shows, including the lead roles in ''Summer of '42
and the original production of Bubble Boy.'' Later in 2013, McCarrell was cast in a concert of
35MM. The show was on October 7, 2013, at
54 Below and the cast included many Broadway stars such as
Lauren Pritchard (
Spring Awakening),
Lesli Margherita (
Matilda), and
Zachary Levi (
First Date), among others. McCarrell went on to audition for the 2014 Broadway Revival of
Les Misérables, originally reading for the role of
Marius Pontmercy. However, a few months after his original reading, he was called back to audition for one of the other students,
Joly. McCarrell was then hired to perform as Joly, as well as understudy the role of Marius. During the same year, McCarrell was cast as Lost Boy Nibs in the
NBC television special,
Peter Pan Live! which aired on December 4, 2014. After a brief rehearsal period, McCarrell officially replaced cast member
Andy Mientus in
Les Misérables on March 3, 2015, and performed as Marius at the
Imperial Theatre until the show's closing on September 4, 2016. On June 1, 2015, McCarrell performed a sold-out solo concert at
54 Below, and appeared there again on December 7, 2015 in "Christmas Carols with Chris McCarrell". Following the end of
Les Misérables, McCarrell performed as the titular character in
The Lightning Thief: The Percy Jackson Musical, which ran from March 23, 2017, to May 6, 2017, at the
Lucille Lortel Theatre. On August 28, 2017, he reprised his role as Percy in a sold-out
The Lightning Thief musical concert at The Green Room 42. In late 2019 to early 2020, he played Percy in the Broadway run of
