London Broil on the Grill FAQs
London Broil actually refers to a method of cooking steak that involves marinating, grilling, and thinly slicing the beef. It is usually known as a flank or top-round steak that is marinated overnight. This technique is perfect for making the most affordable steaks as tender as more expensive cuts, so it's a great choice for entertaining!
I like to grill my London broil steak at about 400°F. This gives it a delicious sear on the outside but keeps it tender and juicy with the perfect temperature on the inside. High heat is the key to the perfect London Broil.
You will need at least ½ a pound of meat per person. This recipe calls for a 2 to 2½ lb. steak and feeds approximately 4 people.
When marinated with my London broil marinade and grilled at the perfect temperature of 400°, London Broil will melt in your mouth!
London Broil Recipes Substitutions
The best part about this London Broil on the Grill marinade is that you can swap out ingredients if you have some on hand but not others. Here are some substitution choices:
- The Asian Marinade works well on top round, flank, flap, or skirt steak
- Vegetable oil instead of olive oil
- Freshly minced garlic or garlic paste instead of garlic powder
- Red wine vinegar instead of balsamic vinegar
- Honey or a mix of white sugar and maple syrup instead of brown sugar
- Ground allspice, cinnamon, or nutmeg instead of ginger

How to Tenderize London Broil
The best way to tenderize steak is to marinate it in the most delicious Asian flavors. I whipped up a beautiful marinade to use in this dish, and let it marinate for at least 4 hours ahead of time. My recommendation is to let it marinate overnight for perfectly tender steak the next day.

WOW!! What a delicious marinade and can’t believe how beautiful this London Broil came out on the grill. I’m teaching myself to grill and had beginners luck thanks to you. Awesome recipe. Followed what you said exactly!!!
Em Beitel says
That is so awesome to hear, Pennina! We're so glad you enjoyed it! Have fun grilling!
Kelly says
Fabulous! The cooked marinade was perfect on the meat - like a lighter version of steak sauce. I used half low sodium soy sauce and half regular, as we are watching the sodium in our diet. Other than that, pretty much followed the recipe. Marinated for about 12 hours.
Isabel Laessig says
Kelly, that is wonderful to hear! So glad you enjoyed it - thank you for your comment and review.
Erica says
This recipe looks delicious! Can the steak be cooked in a cast iron skillet?
Isabel Laessig says
Hi Erica! Absolutely, you can cook the steak in a cast iron skillet if you'd like. Sear over medium-high heat for 3 minutes, then flip and sear another 3 minutes. Take off the heat and tent the pan with foil. The steak should finish cooking in about 10 minutes max (it might be done as early as 5), but make sure to use a meat thermometer to check. If you want it more done than that, cook it for a bit longer in the pan. Make sure to let it rest for at least 10 minutes outside of the pan, too, after it's done cooking.
Enjoy!
