Ingredients

  • 1/4 cup soy sauce
  • 1/4 cup Worcestershire sauce
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons chopped fresh cilantro
  • 1 tablespoon chopped fresh ginger
  • 1 1/4 pounds flank steak

Instructions

  1. Mix soy sauce, Worcestershire sauce, lemon juice, cilantro, and ginger. Marinate the flank steak in the sauce overnight.
  2. Drain the marinade and grill the steak for 5 minutes per side for rare doneness.
  3. Transfer the steak to a platter, slice thinly as for London Broil, and pour the marinade over the meat before serving.

Tips & Substitutions

For a deeper flavor, marinate the flank steak for at least 6 hours, or up to 24 hours if time permits. If you don't have flank steak, skirt steak or sirloin can be good substitutes. To enhance the marinade, consider adding a touch of brown sugar or red pepper flakes for sweetness and heat. Make sure to let the steak rest for a few minutes after grilling for juicier slices.

Serving Suggestions

Serve the sliced flank steak over a bed of rice or alongside grilled vegetables for a complete meal. It pairs beautifully with a fresh salad or crusty bread. For a unique twist, consider serving it with a side of cilantro-lime rice or incorporating it into a fajita setup with tortillas and toppings. This dish is perfect for summer barbecues or family gatherings.

Storage & Reheating

Store leftover flank steak in an airtight container in the refrigerator for up to 3 days. To reheat, slice the steak and warm it gently in a skillet over low heat to avoid drying it out. Alternatively, you can microwave it in short bursts, covered, to retain moisture.

Frequently Asked Questions

Can I use a different cut of beef for this recipe?

Yes, you can substitute flank steak with skirt steak or sirloin. Both options will provide a flavorful result, but keep in mind that cooking times may vary slightly depending on the cut.

How can I tell when the flank steak is done?

For rare doneness, grill the steak for about 5 minutes on each side. Use a meat thermometer to check the internal temperature, which should read 125°F for rare, 135°F for medium rare, and 145°F for medium.

What should I do with leftover marinade?

It’s best to discard the marinade after use, as it has been in contact with raw meat. However, if you want to use it as a sauce, bring it to a boil for at least 5 minutes to kill any bacteria before serving.
