What type of stock is an au jus?

An au jus is primarily a light, thin beef stock that is typically made from the natural juices released from the meat during cooking, particularly for roasted meats, such as beef. This preparation maintains a delicate flavor profile, allowing it to enhance the dish without overpowering it. It is often served alongside the meat as a dipping sauce or liquid to provide moisture and enhance the meat's flavor.

The characteristics of an au jus emphasize simplicity and richness in beef flavor, distinguishing it from thicker stocks or sauces that would significantly alter the overall taste of the dish. It is also a common accompaniment to dishes like French dip sandwiches and roast beef dinners. The focus on a thin consistency in au jus is vital as it is designed to complement the meat rather than serve as a standalone sauce or a base for another dish.
