Tips & Substitutions

For optimal flavor, marinate the steak for the full 12 hours; this allows the vinegar and soy sauce to tenderize the meat. If you don't have flank steak, skirt steak is a great substitute. For a different flavor profile, consider adding herbs like rosemary or thyme to the marinade. Also, make sure to let the steak rest after grilling to ensure juiciness.

Serving Suggestions

Serve the grilled London broil with a side of roasted vegetables or a fresh salad for a balanced meal. It pairs beautifully with Brussels Sprouts With Mustard Sauce for a delicious contrast. You can also slice the steak thinly for sandwiches or tacos, adding your favorite toppings for a fun twist.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the steak slices in a skillet over low heat or briefly in the microwave, taking care not to overcook them, as this can dry out the meat.

Frequently Asked Questions

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

Yes, you can substitute flank steak with other cuts like skirt steak or sirloin. Just keep in mind that cooking times may vary depending on the thickness and tenderness of the cut you choose.

What can I do with the leftover marinade?

It's not recommended to reuse the marinade without cooking it first, as it contains raw meat juices. Instead, you can bring it to a boil in a saucepan for a few minutes to kill any bacteria, then use it as a sauce for the grilled steak.

How do I achieve the perfect doneness for my steak?

For medium-rare, aim for an internal temperature of 130°F to 135°F. Use a meat thermometer for accuracy, and remember to let the steak rest after grilling to allow juices to redistribute for the best texture.
