Skirt steak is a flavorful, relatively lean cut from the diaphragm muscle of the cow, prized for its rich beefy taste and tender texture when cooked properly. It's an economical choice that delivers restaurant-quality results with minimal preparation, making it ideal for grilling, pan-searing, or marinating. Home cooks love skirt steak because it cooks quickly, absorbs marinades beautifully, and develops a delicious crust when seared at high heat.
