Herb-Crusted Flank Steak With Tomato-Olive Relish

Herb-crusted flank steak with tomato-olive relish should be in your recipe repertoire no matter what.  Seriously, if you are a beef eater, it’s a keeper.  A simple fresh herb coating brings great earthy flavor to this dish. The sweetness of ripe seasonal tomatoes paired with briny olives complement the texture and flavors of the steak.  I prefer to pan-sear this recipe, but grilling it is an option as well.  This is also a great recipe for groups, so easy to prep ahead of time, leaving you plenty of time to spend with guests.  This recipe also works well served room temperature with a great crusty bread, making it a nice option for a Sunday lunch with friends. Serve this steak with a great IPA and you can’t get much better.

Flank steak is beef steak cut from the abdominal muscles or lower chest of the cow, and it is often overlooked in the steak world.  A less expensive cut, I like it because it’s versatile, you can be grill, pan-fry, broil, or braise it for increased tenderness.  Not all cuts are so versatile. Marinating a cut like flank steak adds tremendously to the flavor and tenderness.  Flank steak can handle a long 4-hour marinade if you have time to plan for that.  While it’s not necessary in this recipe, I suggest you try that trick at least once.flank steak

How to tell is the steak is done is a question I am asked often.  The truth is, it’s tricky, by touch is the best method and the way I do it, but that just takes practice.  Contrary to popular belief, cutting into your steak to take a quick look is also completely fine.  There is really only a negligible amount of juices lost in doing so and therefore ok in my book.  There is also absolutely nothing wrong with using a thermometer.  A simple digital thermometer is a very useful gadget to have in the house. Above is a handy chart that gives you a simple breakdown of doneness, a description of what that means, temperature ranges and a great visual of how the meat looks.
