Flank steak is a lean, flavorful cut from the lower chest or abdominal muscles of the cow. Known for its rich, beefy taste and coarse texture, it’s ideal for grilling, broiling, or stir-frying. To achieve the best tenderness, it should be marinated and sliced thinly against the grain. This versatile cut is popular in dishes like fajitas, stir-fries, and steak salads. While not as tender as some other cuts, its robust flavor makes it a favorite for bold, hearty recipes.
