WHAT IS FLANK STEAK?

Flank steak is a thin cut of beef coming from the belly of the steer. It’s lean and flavorful meat that’s one of the more budget-friendly cuts of beef. The only catch is that it needs marinating to become tender.

Flank steak is typically grilled at high heat to medium rare doneness and then sliced thinly across the grain. You can eat flank steak on its own, with steak tacos and steak fajitas being some other popular flank steak recipes.

 

HOW TO MARINATE STEAK

The best steak marinade will include acidic ingredients such as lemon/lime juice, vinegar, soy sauce and/or red wine to break down the muscle fibers in the meat. You’ll also need seasonings like garlic, herbs and honey to build a delicious flavor contrast.

Combine the marinade ingredients in a bowl large enough to accommodate your steaks easily. Whisk together and add the steaks, turning several times to coat all sides thoroughly. Cover the bowl with plastic wrap and refrigerate until ready for use.

When it’s time to cook, remove the steak and let the excess marinade drip off before cooking. Otherwise, the marinade will cause the outside of the flank steak to char.

Leftover marinade should be discarded, since it has bacteria from the raw meat. However, it is possible to make a delicious sauce with it by boiling for several minutes in a saucepan before serving.

HOW LONG TO MARINATE STEAK

Flank steak requires at least 2 hours of marinating to become tender, although 30 minutes is sufficient for other cuts such as sirloin. The maximum is 24 hours to avoid the meat losing its texture.

Place the marinating steaks in the fridge to keep the meat fresh. However, it’s a good idea to remove from the fridge 30-60 minutes before grilling to bring the meat closer to room temperature for even cooking on the grill.

Flank Steak Marinade

This flank steak marinade makes the juiciest and most flavorful grilled flank steak! This flank steak recipe uses soy sauce and other ingredients to tenderize the meat and produce an unforgettable meal.
Prep Time: 10 mins
Cook Time: 10 mins
Resting Time: 2 hrs
Total Time: 30 mins
Servings: 6 servings

Ingredients

  • 1/3 cup soy sauce
  • ½ cup olive oil
  • 2 tbsp Worchestershire sauce
  • ¼ minced onion
  • 2 tbsp honey
  • 2 tbsp green onions, minced
  • 3 large cloves garlic, minced
  • 1 tbsp Italian seasoning, or fresh thyme and rosemary
  • ½ tsp black pepper
  • ½ tsp salt
  • 1 tbsp lime juice, or red wine vinegar
  • 2-4 lb flank steak

Instructions

  • Add all ingredients except the steak to a large bowl. Whisk together until fully combined.
  • Add the steak to the bowl and turn several times to coat thoroughly.
  • Cover the bowl in plastic wrap and place in the fridge for 2-24 hours.
  • Remove the steak from the fridge. Preheat grill for medium-high heat, about 400°F (204°C).
  • Spray the grill grates with cooking oil spray.
  • Place flank steak on the grill, discarding the marinade or boiling it down in a saucepan to make sauce.
  • Grill for 2 minutes to sear. Then flip the steak and grill 2 minutes more on the other side.
  • Lower the heat to low and continue cooking for 2-3 more minutes to desired doneness (see note).
  • Remove to a cutting board and let the steak rest covered for 5 minutes (this is so the juices retreat into the meat)
  • 10. Slice thinly across the grain and serve.

Notes

  • You can also marinate the flank steak in a large ziptop bag instead of a bowl.
  • Preheat the grill so the grates are hot before putting the steak on in order to get a good sear.
  • Flank steak is best cooked medium rare to medium; measure with an instant-read thermometer: 125°F (52°C) for rare, 130°F (54°C) for medium rare and 140°F (63°C) for medium. The temperature will rise several more degrees while resting.
  • Avoid piercing/cutting into the steak while cooking, as the juices will escape causing the meat to dry out.
  • Slice flank steak easily using a sharp carving knife or a large serrated knife.
