The Flat Iron Steak

What is a Flat Iron Steak?

A Flat Iron Steak, also referred to as a butlers' steak, feather blade steak, a top blade steak or oyster blade steak, is a cut of beef from the shoulder blade of the cow. It’s a very lean, flavorful cut that’s tender and juicy when cooked correctly. The average 4 oz serving of Flat Iron Steak has about 136 calories, 23 grams of protein and only 2 grams of fat. This cut is best cooked using dry heat methods such as grilling, broiling, roasting or pan-frying. It should be cooked to an internal temperature of 145°F. It's a great choice for a steak sandwich, or sliced into fajitas.
