The French song played during the end credits of Ratatouille is “Le Festin.”
Written by composer Michael Giacchino and performed by French singer Camille, the song is the film’s central original vocal piece. Its title translates to “The Feast,” fitting a story about food, ambition, and the joy of cooking. Camille sings it in French in almost every version of the film.
“Le Festin” was the first musical cue Giacchino wrote for Ratatouille. He shaped the soundtrack around Parisian musical colors, including accordion, violin, clarinet, piano, café sounds, folk-pop, and gypsy jazz. The song appears in the soundtrack’s first track, while the longer instrumental suite “End Creditouilles” is listed separately.
A common mix-up is to identify the closing music as one of several famous French standards, such as “La Vie en Rose” or “Non, je ne regrette rien.” Those songs are not Ratatouille’s signature end-credit song; “Le Festin” was created specifically for the Pixar film.
