Why this long, flat abdominal cut became a global culinary staple
In short: Flank steak is a distinct, grain-heavy cut from the cow's abdomen that requires specific preparation to master. Once an overlooked, budget-friendly butcher's cut, it evolved into a centerpiece of global cuisine. Understanding its unique anatomy and history is the secret to transforming this lean, flavorful meat into a tender meal.
Flank steak is harvested from the abdominal muscles of the cow, situated between the plate and the rear quarter. Because the muscle is long, flat, and defined by a prominent grain, it can be notoriously chewy if handled incorrectly. The essential rule for any chef is to slice the cooked meat against the grain, which shortens the muscle fibers and creates a smooth, tender texture. While often confused with skirt steak—which originates from the plate—the flank is a separate cut with its own culinary identity, appearing in everything from carne asada to stir-fry beef.
The history of the cut is a tale of shifting cultural preferences. While North Americans only embraced flank steak in the mid-1900s, partly due to soldiers returning from the World Wars, South American cultures in Argentina, Chile, and Brazil have utilized the cut since the late 1700s. This early adoption was driven by a tradition of using the entire animal to minimize waste, a stark contrast to the North American preference for more tender cuts. By the early 20th century, European butchers frequently sold the flank at lower prices, as it remained a relatively obscure option before its eventual rise to popularity.
Today, the cut is celebrated for its versatility, appearing in diverse preparations like the London broil or as a premium base for steak jerky. Nutritionally, a 100-gram serving provides 28 grams of protein and 192 calories, according to US Department of Agriculture standards. Whether it is braised in Colombia as sobrebarriga or grilled as churrasquito de vacío in Argentina, the flank steak remains a testament to how culinary ingenuity can elevate a humble, hardworking muscle into a global favorite.
