She took part in the world premiere of the new original musical, Bandstand, directed and choreographed by Andy Blankenbuehler, which premiered at the Paper Mill Playhouse, New Jersey from October 8 through November 8, 2015.

Following the closing of Bandstand, Osnes has performed frequently in the Broadway Princess Party show that premiered at Feinstein's/54 Below, which she also hosts and co-developed with music director Benjamin Rauhala. The Princess Party has become a recurring live event at that venue that gathers both popular and up-and-coming stage actresses; at these performances, each actress assumes the identity of a Disney Princess and performs a song from stage or screen in character as that princess, with Osnes typically emceeing and performing as Cinderella. She also performs in this show on the road consistently with fellow Broadway actresses Susan Egan (Beauty and the Beast, Hercules) and Courtney Reed (Aladdin).
