Intro
When it comes to preparing London Broil, one of the most common questions I hear is, “How long London Broil?” This cut of beef, typically flank steak, deserves a bit of special attention since the right cooking time can make all the difference between a tough meal and a tender masterpiece. In this article, I’ll share everything you need to know, from marinating to cooking times and those all-important serving suggestions.
Ingredients

Let’s kick things off with what you’ll need. First up, of course, is the star of our dish: flank steak. This cut is widely recognized as the best option for a juicy London Broil. But don’t forget about the magical marinade!
Main ingredient
– Flank steak
This cut of beef is lean, flavorful, and perfect for grilling or broiling.
Marinade ingredients
Now, let’s get into the fun stuff—the marinade. You’ll want:
– Soy sauce: Adds umami and saltiness.
– Garlic: For that aromatic burst of flavor.
– Olive oil: Keeps everything moist and tender.
– Spices/seasonings: Think black pepper and, if you’re feeling adventurous, a bit of Dijon mustard for extra zing.
Preparation Steps

Alright, with your ingredients ready, it’s time to prep.
Marinating the meat
First, marinate your flank steak. A solid soaking time is key here. I usually recommend anywhere from 4 to 24 hours. The longer, the better! This allows those flavors to soak in, making your meat explode with taste.
Tips for effective marination
Make sure to coat the steak evenly in the marinade and place it in a zip-lock bag for easy handling. Don’t be shy about kneading that marinade into the steak a bit!
Preparing the grill/oven
Next, you’ll want to prepare your cooking surface.
Temperature settings
Whether you’re grilling or broiling, aiming for a medium-high temperature is ideal. For grilling, think about 450°F, while for broiling, your oven should be set to the same range.
Preheating process
Preheat your grill or oven well before adding the steak to ensure those beautiful grill marks or that crispy outer layer.
Cooking Instructions
Now for the moment we’ve all been waiting for—getting the steak cooked to perfection!
Cooking time
So, how long does London Broil take to cook? Depending on thickness, it generally takes about 6 to 10 minutes per side, or around 12 to 20 minutes total depending on how you like it.
Cooking methods
You can choose to either grill or broil.
Grilling
Grilling can give a nice char and smokey flavor. Keep an eye on it, flipping halfway through to avoid burning.
Broiling in the oven
If you’re broiling, place the steak about 3 to 4 inches from the heat source and check after 6 minutes.
Monitoring the temperature
Using a meat thermometer is critical! You’ll want to hit about 130°F for a medium-rare doneness. Remember that the steak will continue to cook slightly after removing it from the heat—this is called carryover cooking.
Post-Cooking Process
You’ve cooked the steak, but we’re not quite done yet!
Resting the meat
Let it rest for about 10 minutes after it’s cooked. Trust me, this is crucial for that tender cut.
Slicing the London Broil
When it’s time to slice, make sure you do so against the grain. This helps break up the muscle fibers and gives you the tender bites.
Serving Suggestions
Now, let’s talk about what to serve with this delicious dish.
Ideal accompaniments
You can pair it with roasted veggies or creamy mashed potatoes. How about a side salad to add some freshness?
Presentation tips
Slice the London Broil thinly and arrange it on a platter. Drizzle a bit of the leftover marinade to make it visually appealing.
