By: Sandy Manual, LDN, RD


  • 2 lb. Flank steak or London Broil or Flat Iron Steak

In a Tupperware or zip lock bag combine oil, vinegar, garlic, salt and pepper with steak. Let marinade for as little at 1 hour or all day (I marinade mine that morning to cook that night). Preheat oven to 475 degrees F. Bake for 10 minutes. While baking heat up a cast iron skillet with 1 tbsp. butter. Pull steak out of oven then brown in skillet for 3 minutes on each side. Pull from skillet to let steak rest for 10 minutes. Cut and serve.

I paired my steak with roasted potatoes, broccoli and mushrooms. (Olive oil, rosemary, and little salt and pepper baked in oven for 20 minutes at 475 degrees F.)
