Step 1: Prepare the Marinade
In a medium-sized bowl, whisk together the soy sauce, olive oil, lime juice, honey, minced garlic, Worcestershire sauce, smoked paprika, black pepper, and red pepper flakes. Ensure the honey is fully dissolved and the ingredients are well combined.

Step 2: Marinate the Steak
Place the flank steak in a large resealable plastic bag or shallow dish. Pour the marinade over the steak, ensuring it’s fully coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, preferably overnight. The longer the steak marinates, the more flavorful and tender it will become.

Step 3: Preheat Your Cooking Surface
If grilling, preheat your grill to medium-high heat (around 400°F). For stovetop cooking, heat a cast-iron skillet or grill pan over medium-high heat.

Step 4: Cook the Steak
Remove the steak from the marinade and let any excess drip off. Discard the used marinade. Place the steak on the grill or pan and cook for 4-6 minutes per side for medium-rare, or until the internal temperature reaches 130-135°F. Use a meat thermometer for accuracy.

Step 5: Rest and Slice
Once cooked, transfer the steak to a cutting board and let it rest for 10 minutes. This allows the juices to redistribute, ensuring a juicy steak. Slice the steak against the grain into thin strips for maximum tenderness.
