What Is Beef Barbacoa?

Barbacoa is a traditional Mexican cooking method that involves slow-cooking meat until it becomes exceptionally tender. Historically, barbacoa was prepared by wrapping meat in agave leaves and cooking it underground. While most of us are not digging pits in our backyards, the slow cooker perfectly mimics that low-and-slow environment.

Modern beef barbacoa tacos typically feature beef chuck or beef cheeks cooked with dried chilies, garlic, vinegar, and spices. The result is rich, bold, and deeply satisfying. This recipe stays true to those flavors while keeping the process approachable for everyday kitchens.
