FAQs

What cut of meat is London Broil?

London Broil typically refers to top round or flank steak, both of which are lean cuts ideal for marinating and grilling.

How do I make it more tender?

Marinating is key—acidic ingredients like vinegar or citrus help break down the fibers. Slicing thinly against the grain also ensures tenderness.

Can I marinate it too long?

Yes, over-marinating (especially over 24 hours) can make the texture mushy due to the acid breaking down the muscle too much.

What’s the ideal temperature for doneness?

Medium-rare is ideal (130–135°F). Use a meat thermometer for accuracy.

Can I cook it in a skillet instead of grilling?

Yes. Sear in a cast iron skillet over high heat for about 4–6 minutes per side.

Should I let it rest after grilling?

Absolutely. Resting allows the juices to redistribute, making the steak juicier.

Why do I need to slice against the grain?

Slicing against the grain shortens muscle fibers, making each bite easier to chew and more tender.

What sides go well with London Broil?

Try roasted potatoes, grilled vegetables, coleslaw, or a crisp green salad.

Can I reuse the marinade?

No, discard used marinade unless you boil it first to kill bacteria.

Is London Broil good for meal prep?

Yes. It slices well and can be used in sandwiches, salads, wraps, or grain bowls throughout the week.

Conclusion

Grilled London Broil is a flavorful, affordable steak option that’s easy to prepare and sure to impress. With the right marinade, proper grilling, and careful slicing, this lean cut transforms into a tender, juicy centerpiece perfect for any dinner table.
