In 2009 Blythe debuted at the San Francisco Opera portraying the role of Azucena in Il Trovatore.[6] In 2010 she made her debut at the Lyric Opera of Chicago as Ulrica, and was also seen in Chicago that season as Katisha in The Mikado. The Chicago Sun-Times review of the latter performance stated, "Blythe explodes onto stage ... an enormous woman with enormous talent, a big, powerful voice and an elastic comic face".[7]Chicago Classical Review added,
"Blythe ... steals the entire show. ... It’s unlikely that this supporting role has ever been sung with this caliber of gleaming operatic voice. She ... threw off the rapid-fire patter duet "There is beauty in the bellow of the blast" with blazing speed and crystal-clear diction. Blythe also displayed a great comedian’s timing making every punch line register. And, for a woman of such imposing physique, she showed herself a graceful and light-footed presence with her little victorious dance steps."[8]
On April 18, 2013, Blythe performed works made famous by Kate Smith on the PBS program Live from Lincoln Center - Celebration: Stephanie Blythe Meets Kate.
In June 2014, Blythe premiered the starring role of Gertrude Stein in Twenty-Seven, a new opera by Ricky Ian Gordon (music) and Royce Vavrek (libretto), commissioned for her by the Opera Theatre of Saint Louis.

Her male range is that of a tenor, overlapping with the lower end of a her mezzo-soprano voice. She has performed pieces from various genres including opera, rock, and musical theatre.[10] In September 2021, she debuted as Don José in Carmen at the Chicago Opera Theater, with Jamie Barton in the title role.[11] In a San Diego Opera production in 2023, she performed as a baritone for the first time, singing the title role of Gianni in Puccini's one-act comic opera Gianni Schicchi.[12]
