Flat Iron Steak

If you’ve never tried flat iron steak, now is the time. Also known as the top blade, it’s taken from the shoulder and has a deep, meaty flavor that pairs pleasantly with full-bodied sauces.

This cut used to be thought of as tough and sinewy, but researchers discovered a way to slice the steak that leaves a lean cut with rich streaks of fat. Who knew science could be delicious?

Flat iron steak is great for grilling, or you can sear it over high heat and use a meat thermometer to ensure the perfect cook.
