The Best London Broil Recipe
This London broil recipe is melt in your mouth delicious, flavorful, juicy and a great way to feed a crowd on a budget. This restaurant quality London Broil roast is seasoned with the easiest and most delicious marinade and cooks in about 10 minutes.
After marinating the flank steak, I quickly sear it in a skillet and then I finish the cooking in the oven. The entire cooking process takes very little time, which makes this steak recipe a great meal to make on busy weeknights.
Some recipes instruct you to broil the steak in the oven however, I find that this method can make the beef very dry and if you don’t keep an eye on it, it can be a total disaster.
What Cut Of Meat Is London Broil?
London broil was originally made exclusively with flank steak, although through the years other cuts of beef like top round steak have been sold with that name.
It is important to know that London broil is actually not a cut of meat but a preparation. Some London Broil recipes are made on the grill, some are obviously broiled and some are pan fried.
How To Tenderize London Broil
Marinating London Broil helps to tenderize the meat. Marinating is similar to brining. Marinating not only adds flavor, it also adds moisture to the meat, preventing it from drying when cooked. The acidity in the marinate changes the surface texture, making the beef more tender.
Can You Marinate London Broil Too Long
The quick answer is yes. Marinades contain acids like vinegar and citrus juice or enzymes like papaya and mango. If you marinate the meat for too long, the meat will get mushy and tough. Don’t marinate your London Broil for any longer than 8 to 12 hours.
What Does London Broil Taste Like?
London broil or flank steak is a tough cut of meat with a relatively mild taste. This type of beef benefits from a tasty marinade with enough acid to tenderize the meat while adding lots of flavor.
How To Cook London Broil?
- Make The Marinade: First, mix the London Broil marinade ingredients in a small bowl. Place the round steak or flank steak in a shallow dish or in a large resealable bag. Pour the marinade over the roast and marinate for one hour to 8 to 12 hours
- Sear The Beef: When ready to cook, preheat the oven to 425 degrees Fahrenheit. Remove the London Broil roast from the marinade and pat dry with paper towels (this will help get the meat golden brown). Heat the oil in a large skillet over high heat. Sear the beef for about 2 minutes per side.
- Finish Cooking In The Oven: Place the skillet in the heated oven and cook for about 6 minutes or until the steak reaches your desired temperature.
- Rest, Slice And Serve: Remove the steak from the oven and allow it to rest, tented with aluminum foil for about 5-10 minutes. After this resting period, slice the beef against the grain and serve.

London Broil Recipe Tips
- Marinate the beef for one hour to 8 to 12 hours. Marinating the steak is essential in this recipe as it adds lots of flavor while tenderizing the meat.
- If you marinate the steak for longer than an hour, remove the meat from the refrigerator about 30 minutes before cooking it so it’s not too chilled.
- Remove the meat from the marinade and pat dry the beef with paper towels. Drying the meat ensures a nice golden brown sear on the London broil.
- Sear the meat over high heat and cook quickly to prevent over cooking.
- Do not over cook the meat. For tender and juicy London broil, the flank steak should be cooked to medium-rare (130 – 135 degrees Fahrenheit).
- Allow the beef to rest for 5 to 10 minutes before slicing it.
- Slice the beef against the grain.

In step 6, after coming out of the oven is the steak to be taking out of the pan before tenting it and letting it rest 5 minutes? The instructions didn’t say so but it seems like instead of resting it still be cooking instead of resting if tented while in the pan.

Hi Jayne! Take the pan from the oven and tent the meat. The meat can be left in the pan. I hope this helps!!

Very tasty. I ended up extending the cooking time a bit. Served with rice medley, a vegetable stir-fry, and sliced tomato. It might be interesting to try adding a bit of grated gingerroot to the marinade.
