Flank steak is our favorite cut of beef. It’s lean yet very tender and flavorful and it’s a great cut of beef to marinate. I found a recipe for a flank steak marinade on Kalyn’s Kitchen that sounded perfect and I happened to have all ingredients on hand. I only marinated the beef for 4 hours and it was very flavorful but next time I make this, and there WILL be a next time, I will let it marinate for 24 hours. The steak had a terrific flavor and my entire family enjoyed it. The flank steak paired nicely with the Balsamic Roasted Tomatoes with Fresh Basil.
Combine the olive oil, balsamic vinegar, Dijon mustard, Worcestershire sauce, minced garlic, lemon juice, paprika, oregano, basil, and thyme together in a large zip lock bag. Seal the bag and shake until well combined. Add the flank steak and refrigerate for at least 4 hours up to 24 hours.
Remove the flank steak from the refrigerator 20 minutes prior to cooking. Heat a grill pan over medium high heat and coat with cooking spray. Add the flank steak to the HOT grill pan and cook 4-5 minutes then flip and continue cooking for 2-3 minutes for medium rare; or until you have reached your desired degree of doneness. Remove from the grill pan and place on a cutting board to rest for 5 minute prior to slicing against the grain. Serve and enjoy.
