What is the name of the female chef at Gusteau's?

The female chef at Gusteau’s is Colette Tatou.

Colette is the kitchen’s only female chef and one of its most capable professionals. She has risen through the male-dominated world of haute cuisine by combining technical skill, discipline, and a forceful personality. When Alfredo Linguini starts working at the restaurant, Colette is assigned to train him.

At first, she is skeptical of Linguini’s lack of experience and impatient with his mistakes. Her strict instruction reflects the demanding hierarchy of a professional French kitchen, where speed, precision, and teamwork matter. She eventually becomes emotionally close to Linguini while continuing to play an important role in the restaurant’s operation.

Colette is voiced by Janeane Garofalo in the English-language film. Her surname, Tatou, is sometimes omitted, leading players to answer simply “Colette,” but “Colette Tatou” is the character’s full name and the clearest canonical answer.
