Flat iron steak, also known as butler's steak or oyster blade steak, is a flavorful and relatively tender cut of beef derived from the shoulder of the animal, specifically the top blade muscle. This cut is prized for its rich, beefy flavor and generally good marbling, offering a more budget-friendly alternative to other premium steaks. Flat iron steak is characterized by its uniform thickness and rectangular shape, making it ideal for even cooking. When properly prepared, flat iron steak delivers a satisfying eating experience, balancing tenderness and a robust, savory taste. It is often praised for its tenderness to the point it is almost as tender as filet mignon.

Flat iron steak is best stored in the refrigerator at temperatures below 40°F (4°C). Wrap it tightly in plastic wrap or butcher paper, then place it in a sealed container or zip-top bag. Use within 3-5 days for optimal quality. For longer storage, freeze the steak wrapped tightly to prevent freezer burn; it can be stored frozen for up to 6-12 months. Thaw in the refrigerator before cooking.
