What to look for
A true flat iron has the tough central connective tissue removed. If the package is labeled top blade, inspect how it was fabricated or ask the meat counter whether the gristle seam remains.
How to cook it
Use a hot pan or grill and avoid overcooking. Rest briefly, identify the grain, and slice across it. Its even thickness makes it easier to control than skirt steak.
How this cut saves money
Use flat iron for steak plates, salads, and fajitas when skirt or ribeye pricing climbs. The combination of usable yield and tenderness often matters more than the absolute lowest sticker price.

Common questions
Is flat iron more tender than skirt?
Usually, yes. Skirt has stronger fibers and depends more heavily on thin cross-grain slicing.
Does flat iron need a marinade?
No. A marinade adds flavor but a properly trimmed flat iron is naturally tender enough for simple seasoning.
