This easy marinade makes grilled flank steak the crowd-pleaser that it should be. The nice thing about flank steak is it has a thin end and a thicker end, so some can have it a little rarer, and some a little more well done. When you have a crowd with mixed tastes in their steak's depth of cooking, this dish always hits the spot.

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat-resistant, tempered glass products can, and do, break occasionally.

Tip

  • This flank steak is best cooked over a hot charcoal fire, but it will also work on a gas grill, indoor grill pan, or broiled.
