Espagnole sauce is a basic brown sauce, and is one of the mother sauces of classic French cooking. In the early 19th century the chef Antonin Carême included it in his list of the basic sauces of French cooking. In the early 20th century Auguste Escoffier named it as one of the five sauces at the core of France's cuisine.

In French cuisine, the mother sauces, also known as grandes sauces in French, are a group of sauces upon which many other sauces – "daughter sauces" or petites sauces – are based. Different sets and classifications of mother sauces have been proposed since at least the early 19th century.
