The flat iron steak is a cut developed several decades ago to get a tender steak from an area of the cow that thought too tough to eat. Flat iron steaks are specifically the top muscle blade of the shoulder, or "chuck," region of a cow. Although the chuck region is typically tough, the top blade muscle is not. There are only two top blade roasts in each cow, weighing 1.5 pounds or less. Each roast is cut into flat iron steaks, typically weighing four to eight ounces each and one inch thick.

Flat iron steaks are well-marbled and have a rich, beefy flavor. Unlike other steaks, flat iron steaks do not traditionally have a fat cap, but many are packaged with the connective fat still attached to add extra flavor during the cooking process. Flat iron steak is the second most tender cut of beef, next to filet mignon. Flat iron steaks are much less expensive than a filet mignon or a rib eye but are just as juicy and flavorful. 

Flat irons are named because their flat, thick, rectangular shape is reminiscent of an old-fashioned metal iron. In the UK, flat iron steaks are called butler's steaks because of their inexpensive price tag. Flat iron steaks are known as oyster blade steaks in Australia and New Zealand. In the United States, flat iron steaks may also be called top blade steaks, shoulder top blade steak, and top blade filet.

A three-ounce serving of flat iron steak has 180 calories and provides 23 grams of muscle-building protein. A serving also provides 15% of your daily iron and 70% of your daily zinc requirement.

Flat iron steaks are thin, allowing them to be cooked quickly, even on a busy weeknight. To prepare this versatile cut of meat for cooking, season it with salt and pepper or your favorite beef seasoning blend. Flat iron steaks are also delicious when prepared with a marinade of vinegar, wine, oil, and citrus. Steaks should marinate for a few hours or overnight.

No matter which cooking method you use, always get your steaks out of the fridge 30 minutes to an hour before cooking. Allowing your flat iron steaks to warm up will help you get a nice sear on the outside. The primary cooking methods for lat iron steaks are:

For the most flavorful steak, cook your flat iron steak until a meat thermometer in the thickest part registers 130 degrees Fahrenheit. Your steak will continue to cook (known as "carryover cooking") as it rests until it reaches 135 degrees Fahrenheit, which is medium-rare.

Flat iron steak pairs well with red wines, especially Cabernet Sauvignon. Serve your flat iron steak as you would any other steak, with sides of potatoes, green vegetables, bread, and salad.
