flank steak

Flank steak is a lean, flat cut of beef derived from the abdominal muscles (specifically the rectus abdominis) of the animal, located along the lower portion of the cow's underside between the plate and the rear quarter. This cut is characterized by its long, flat shape and visible grain structure, with deep red coloring and minimal marbling. The muscle fibers run in a distinct diagonal pattern, which directly influences its cooking and slicing properties. Flank steak has a moderately beefy flavor that intensifies with proper searing, though its leaner composition makes it more prone to drying if cooked beyond medium doneness.

The cut is valued in various culinary traditions for its balance of flavor and leanness, making it suitable for grilling, broiling, and quick-cooking methods that respect its texture requirements.

Flank steak is widely used in grilling and high-heat cooking methods, particularly valued in Mexican, Argentinian, and East Asian cuisines. It is the traditional cut for carne asada in Mexican cooking and features prominently in Korean and Thai stir-fried preparations. The pronounced grain structure makes it ideal for marinades, which penetrate quickly and enhance tenderness. When sliced against the grain into thin strips, flank steak becomes tender despite its lean nature. It is commonly paired with bold marinades featuring citrus, soy, garlic, or vinegar-based preparations, and serves well in fajitas, salads, stir-fries, and sandwiches. Proper slicing technique—always perpendicular to the visible grain—is essential for optimal texture.
