What is a Flat Iron Steak?

Flat iron steak, also known as top blade steak, originates from the shoulder section of the cow, also called the chuck primal. It was once overlooked due to the connective tissue running through it, but modern butchery has made this cut more accessible and beloved for its tenderness and flavor. It's popular across the U.S. and globally in restaurants and home kitchens alike.

Flat iron steak is tender and has a rich, beefy flavor, making it a comparable alternative to filet mignon at a lower price point. The texture is smooth and juicy when cooked properly, ideal for grilling, pan-searing, or broiling. It works in a variety of dishes, from steak salads to stir-fries.

Nutritionally, flat iron steak is a powerhouse with high levels of protein, iron, and B vitamins such as B12 and niacin. Despite being a red meat, it's relatively lean when trimmed, making it a great choice for those looking to boost their protein intake while minimizing excess fat.
