Ingredients

The following ingredients have 6 Servings
  • 2 pound flank steak, Note 1 (preferably certified angus beef, prime, AAA or choice cut)
  • 1/3 cup oil
  • 4 cloves garlic, minced
  • 1/3 cup soy sauce
  • 1/4 cup brown sugar or honey ((maple syrup is fine too))
  • 2 tablespoons good quality balsamic vinegar, Note 3
  • 1 teaspoon pepper
  • 1 tablespoon chopped fresh rosemary or thyme - or 1 tsp dried (optional)

Instruction

  • MARINATE FLANK STEAK: Put all the marinade ingredients in a sealed freezer bag. Squish around until well blended. Feel free to add 1/2 teaspoon red pepper flakes if you like heat. Pierce the flank steak all over with a fork or sharp knife to help tenderize the meat. Place flank steak in ziploc bag, seal and refrigerate for 3-24 hours.
  • GRILL FLANK STEAK: Heat the grill to medium-high heat (450-475F/232-246C). Remove flank steak and pat dry with paper towels. Reserve marinade if making a sauce. Spray flank steak with cooking oil (or coat with olive oil). Sprinkle with salt. Grill for 3-4 minutes per side or until internal temperature with an instant meat thermometer reaches 130F/54.4C for medium rare (temp will rise further when resting). Note 4 for other temperatures. The meat should still be fairly soft when you poke it with your finger. Remove from heat and place steak on cutting board. Cover loosely with aluminum foil and let rest 10 minutes (important!).
  • MAKE SAUCE (optional): While flank steak is grilling, pour reserved marinade into a small sauce pan. If you prefer a slightly thickened sauce (I do), stir in 1 teaspoon cornstarch. Boil for a few minutes to ensure all impurities are cooked away. Adjust seasoning and add a tablespoon or two of water if needed to reach desired consistency. The sauce can be boiled for about 90 seconds in microwave instead in a glass measuring cup. Note 2 - other sauce options.
  • SLICE AND SERVE: Slice meat into thin strips against (opposite way of) the grain of the meat at a wide 45-degree angle. Serve warm or at room temperature with your choice of sauce or condiments. Flank steak can also be broiled instead of grilled.
