Cook made her Broadway debut in 1951 in Sammy Fain and Yip Harburg's Flahooley. Her many appearances since have included the roles of Cunegonde in the original production of Bernstein's Candide, Marian the Librarian in the original production of Meredith Willson's The Music Man—for which she won a Tony Award—and Amalia in the original production of Bock, Harnick, and Masteroff's She Loves Me. In 1985, she appeared with the New York Philharmonic in a concert version of Stephen Sondheim's Follies.

She made her solo concert debut in 1975 at Carnegie Hall, and has given solo performances in venues around the world; in 2001, she toured the solo show Barbara Cook in Mostly Sondheim and in 2004 had a hit with Barbara Cook's Broadway.
