Steak is not something we have much at our house. Chicken is our usual meat of choice (I use the word “our” loosely, probably should have said “my”).  I think I can hear my guys now saying “for crying out loud…how many ways can this woman cook chicken?” Anyway, when we do have steak, there are a few golden rules that have to be followed:

the steak must be marinated

the steak must be grilled

the steak cannot have any fat on it and,

the steak must be cooked to well-done!

I don’t agree with the last two…but I grudging go along with it. Which brings me to why I love Flat Iron Steak…it is really lean.

This may be the simplest recipe ever to follow. Just so you know – I buy the steaks that are vacuum packed, in the meat section at the grocery store. My grocery shopping is done every two weeks, so it is really convenient to just throw the package of steak in the freezer until the day I planned to serve it on the menu. Serve the marinated steak with a wedge of lime and Garlic Matchstick Fries!  Enjoy!

Tips and Hints to make the best Flat Iron Steak Recipe:

  • Start with quality meat – use organic beef if possible
  • Use fresh squeezed lime juice for the best flavor and results. If lime zest is required in the recipe, be sure to zest the lime BEFORE squeezing it.
  • When it comes to using spices, keep the shelf fresh by storing spices in a cool, dark place, away from direct heat or sunlight. In tightly closed containers whole spices will stay fresh for about 4 years, ground spices for about 2 to 3 years and dried herbs for 1 to 3 years.
