flank steak -- diagonally sliced

Flank steak is a lean cut of beef from the abdominal area of the animal, located beneath the loin and above the rear legs. This muscle group is highly exercised, resulting in a dense, flavorful meat with pronounced grain structure and minimal fat marbling. The meat possesses a bold, beefy flavor and a slightly chewy texture when improperly prepared, but becomes tender when sliced against the grain.

Flank steak is characterized by its prominent muscle fibers running in a single direction, making the grain orientation critical to preparation. The cut typically weighs 1.5 to 2.5 pounds and is relatively affordable compared to premium steaks, making it popular for everyday cooking. Its texture and flavor profile are particularly well-suited to marinades and high-heat cooking methods.

Flank steak is a versatile cut prized in Latin American, Asian, and American cuisines. It is commonly used in fajitas, stir-fries, and Korean grilled meat preparations where thin, diagonal slicing is essential for texture. The meat benefits significantly from marinades containing acidic components, soy sauce, or enzymatic tenderizers, which break down the muscle fibers and enhance tenderness.

Diagonal slicing (cutting perpendicular to the grain) is the standard preparation method, reducing the effective fiber length and creating a more palatable bite. Common applications include carne asada, bulgogi, Asian noodle dishes, and salads. The cut is ideal for high-heat grilling or pan-searing followed by slicing, and works particularly well when marinated for 4 to 24 hours before cooking.
