Step-by-Step Instructions for Grilled Marinated Flank Steak
Step 1: Prepare Marinade
In a mixing bowl or Ziploc bag, whisk together olive oil, reduced sodium soy sauce, balsamic vinegar, lemon juice, brown sugar, Worcestershire sauce, and Dijon mustard until well combined. Add onion powder, garlic powder, paprika, black pepper, red pepper flakes, and dried herbs, mixing until the sugar dissolves. This flavorful blend is the secret to an irresistible grilled flank steak.
Step 2: Marinate Steak
Place the flank steak in the marinade, ensuring it’s completely submerged. Seal the bag tightly or cover the bowl, then gently massage the marinade into the meat for 2-3 minutes. Let the steak marinate in the refrigerator for at least 2 hours, but for maximum tenderness, aim for up to 12 hours. The longer it sits, the more flavor it absorbs.
Step 3: Bring to Room Temperature
About 30-60 minutes before grilling, remove the marinated flank steak from the refrigerator. Allowing it to come to room temperature ensures even cooking. As it rests, the flavors will intensify, preparing the grilled flank steak for the perfect sear on the grill.
Step 4: Preheat Grill
Preheat your grill to high heat, about 450-500°F (232-260°C), for 10-15 minutes. This high temperature is essential for achieving that delicious caramelized crust on your grilled flank steak. Once preheated, ensure the grates are clean and hot, ready for the steak.
Step 5: Prepare Grill Grates
Using a pair of tongs and a paper towel dipped in oil, carefully wipe the grill grates to prevent sticking. This step allows for optimal searing and beautiful grill marks on your flank steak. Make sure the oil is applied evenly for the best results.
Step 6: Grill Steak
Place the marinated flank steak on the grill and cook for 5-6 minutes per side, flipping only once for even cooking. Monitor the steak closely—aim for a nice char and internal temperature of 130-135°F (54-57°C) for medium-rare. Adjust cooking time depending on your desired level of doneness.
Step 7: Rest Meat
Once achieved, carefully transfer the grilled flank steak to a plate and cover it loosely with aluminum foil. Let it rest for 10 minutes; this allows juices to redistribute, ensuring every bite of your grilled flank steak is tender and juicy.
Step 8: Slice & Serve
After resting, slice the steak against the grain into thin strips for maximum tenderness. Serve immediately as is, or incorporate into your favorite dishes like tacos, salads, or wraps. Enjoy the savory goodness of this grilled flank steak with your family and friends!
