Let’s Make It Together
Prepare to embark on an epic flavor journey as we create this mouthwatering London broil!
Create the Marinade: In a medium bowl, whisk together olive oil, soy sauce, balsamic vinegar, minced garlic, Dijon mustard, and black pepper until well combined. The mixture should be smooth and fragrant.
Add Fresh Herbs: Stir in finely chopped thyme or rosemary for that herby goodness. Their aroma will fill your kitchen and entice anyone nearby to come running.
Pierce the Steak: Use a fork to poke holes all over your flank steak; this allows the marinade to penetrate deeply and enhance tenderness. Visualize those flavor explosions happening inside!
Marinate Overnight: Place your steak in a resealable plastic bag or shallow dish and pour the marinade over it. Seal tightly or cover; refrigerate for at least 4 hours or overnight for maximum flavor infusion.
Grill or Broil Your Steak: Preheat your grill (or broiler) to high heat. Remove steak from marinade (discard leftover marinade), then grill each side for about 5-7 minutes for medium-rare. Watch for those beautiful grill marks!
Let It Rest Before Slicing: After grilling, let your steak rest for 5-10 minutes before slicing against the grain. This step ensures every bite remains juicy and flavorful while preventing dryness.
