In 2019, O'Regan's opera The Phoenix with a libretto by John Caird was premiered at the Houston Grand Opera. The story was derived from the life of Mozart’s librettist, Lorenzo Da Ponte. Patrick Summers conducted the opera with Thomas Hampson and Luca Pisaroni playing Da Ponte at different stages of his life. The designs were by David Farley with lighting by Michael Clarke and choreography by Tim Claydon. Tarik O'Regan was appointed Philharmonia Baroque Orchestra's first-ever Composer-in-Residence in 2021.
