Grilled Flat Iron Steak is a nice cut of steak to choose vs what cut of steak you may normally pick up.

This simple & delicious flat iron steak recipe is made using my go-to grilling marinade. This simple marinade is delicious with flank steak, sirloin steak, top round steak or London broil. This same marinade also works well with chicken, beef, pork tuna and veggies. It gives great flavor to all of these. I especially like using it for grilling kebabs.

You can boil the marinade after removing the steak and serve it alongside the steak as well. Bring it to a boil for a few minutes to kill any bacteria from the raw meat. Or you can make a smaller separate batch of the marinade exclusively for using after the steak has been cooked.

What is Flat Iron Steak?

  • Also referred to as top blade steak, flat iron steak, is a cut of beef from the shoulder region (the chuck). Flat iron steak has rich flavor and tenderness, which is the result of it being cut away from the connective tissue within the shoulder. it's name comes from its flat shape, which resembles an old-fashioned flat iron.
  • Flat iron steaks used to only really be found on steak house restaurant menus since it was extra work for butchers to remove the tough piece of connective tissue that runs through the middle of it. However, improved butchering techniques and its rise in popularity have made this steak more accessible to home cooks.
  • Individual cuts weight about 8-12 ounces each. A whole top blade sut weights 2-3 pounds (as pictured here).
  • Flat iron steak is versatile. You can grill, broil, pan sear.
  • Flat iron steak offers a great balance between cost and quality, making it a favorite for both home cooks and chefs.
