The son of a retired police officer and a housewife, he began singing with a school choir at age 7 and piano lessons at age 9. He studied music at the conservatory in Granada. He later attended the Universidad de Granada, with concentrations in art history and acting. He studied conducting further at the Universidad de Alcalá de Henares. His conducting teachers have included Harry Christophers and Christopher Hogwood.
In the mid-1990s, Heras-Casado participated in the founding of the early music ensemble Capella Exaudi. At the Universidad de Granada, he helped found the ensemble SONÓORA, with a focus on modernist and avant-garde music. In 2000-2001, he was an assistant conductor with the Joven Orquesta Nacional de España. He founded the Barroca de Granada Orchestra in 2002. In 2004, he established an "International Choral Conducting Masterclass" in Valle de Ricote (Murcia). In 2006-2007, he was an assistant conductor with the Opéra de Paris. In 2007, Heras-Casado cofounded La Compañía Teatro del Principe, a period instrument ensemble based in Aranjuez, Spain which focuses on neglected operas of the Spanish baroque era. His work in contemporary music has included conducting the world premieres of Marc-Olivier Dupin's ballet Les enfants du paradis for Opéra National de Paris (2008) and of the opera Matsukaze by Toshio Hosokawa (2011).
He has conducted some major orchestras in Europe and the US. Heras-Casado made his US debut in June 2008 with the Ensemble ACJW at Carnegie Hall, New York. His UK debut followed in August 2008 with the National Youth Orchestra of Great Britain. Heras-Casado first conducted the Orchestra of St. Luke's in the summer of 2011. In December 2011, the orchestra announced the appointment of Heras-Casado as its principal conductor, with immediate effect, and with an initial contract through 2015.
In 2010 he appeared at the Mostly Mozart Festival for the first time, and in 2012 he made his debut at the Salzburg Festspiele.
Heras-Casado's honours have included winning the Lucerne Festival Conductors' Competition in 2007, where he has returned twice to co-direct the festival's Academy at the personal invitation of Pierre Boulez. He received the "Critical Eye" prize of Radio Clásica, part of RTVE, in November 2010.
