inside skirt steak

Inside skirt steak is a lean, flavorful cut of beef derived from the diaphragm muscle (Musculus transversus abdominis) of the steer, specifically the lower abdominal area. Unlike outside skirt steak, which comes from the chest wall, inside skirt is more tender and contains slightly less connective tissue, though it retains a coarser grain structure. It is characterized by pronounced marbling and deep beef flavor, with a buttery mouthfeel when properly cooked. The muscle's constant use results in well-developed flavor compounds, making it prized despite being classified as an economical cut.

Inside skirt steak is most celebrated in Latin American cuisines, particularly in Mexico (arrachera) and Argentina (falda), where it is traditionally grilled over high heat and served with chimichurri or salsa. The cut benefits from quick, hot cooking methods such as grilling, broiling, or pan-searing to achieve a flavorful crust while maintaining a pink interior. It is also commonly marinated in acidic ingredients (citrus, vinegar) to enhance tenderness and flavor penetration. Inside skirt is ideal for fajitas, steak tacos, salads, and carne asada preparations, and slices should always be cut against the grain to maximize tenderness.
