Grilled Flat Iron Steak Marinade Recipe
This “new” cut of meat offers a tasty alternative to more well-known — and more expensive — grilling options. Check out our flat iron steak marinade.
Summertime is grilling season. Hot dogs and burgers are ubiquitous, and these days it seems it’s acceptable to cook virtually anything on the grill. Unfortunately, many of us have been priced out of being able to enjoy the classic grilled steak dinner.
But there is an affordable alternative. The flat iron, or beef shoulder top blade steak, is relatively tender beef muscle, well marbled, and flavorful, yet lean.
Increasingly, this cut is appearing in your supermarket meat case, typically in a vacuum-sealed package. The flat iron was developed by the National Cattlemen’s Beef Association’s Beef Innovations Group in an effort to offer “value-added cuts” to meet consumer needs, while simultaneously making good use of some of the often overlooked parts of beef.
Abattoirs cut along thick internal connective tissue of the beef shoulder to form flat iron steak. The resulting cut resembles a flank steak, and typically ranges from ¾ to 1-1/4 inches thick. Because of its tenderness, the cut is good for stir-fry or kabobs, but you can also marinate and grill it.
However you cook it, slice it across the grain for maximum tenderness, and this flat iron steak marinade recipe makes it even more delicious.
