London Broil In The Oven: Complete Guide + Recipe

Steak can be intimidating in general, more so with parts like flank or top round as they tend to be tougher than more expensive cuts of beef.

So, today I’m sharing another one of my kitchen hacks: how to cook London broil in the oven. AKA How to make an impressive dinner without breaking the bank.

The consistent worry with making London broil is that if cooked incorrectly, you can end up with something close to a murder weapon. It will be tough and gamey, in short – barely edible. I’m here to change that.

Read on to learn everything you need to know about making your very own London broil at home.

Best Way To Cook London Broil In The Oven

We’re usually more familiar with steak being pan-fried in a cast-iron skillet with herb and butter. When making a London broil you have to marinade it first for at least 2 hours to get the best results.

Then the classic method is to pan-fry it, but you risk overcooking the beef.

So, I figured it’s better to cook the London broil in the oven. It’s easier to control and maintain the temperature of both the oven and the meat. Thus, it stays juicy and gives you a perfect medium rare every time.

Step 1. Rest the beef on a cutting board. Make sure its widest side is up because that’s where we will score it. Using a sharp knife, cut 1/8 deep diamond pattern across the beef. Repeat this on the other side.

Step 2. Make the marinade and soak the meat for at least 4 hours before cooking. This is to allow it to absorb all the flavor from the marinade. The cuts will help in making sure that the flavor is not just on the outside but in every slice of the London broil. You can use a resealable bag to submerge the meat, or if you don’t have one then, a nice large Tupperware — big enough to fit it would be enough.

Step 3. Sear and put it in the preheated oven. Let the London broil cook to perfection.

How Long Does It Take For A London Broil To Cook In The Oven?

London broil can be baked in the oven at different temperatures. The baking time depends on how you  want the doneness to be. This is best checked using a meat thermometer or a dual probe food  thermometer. Dual probe thermometer gives you real-time temperature as the meat cooks in the oven  or broiler.  

For a rarely done steak, the temperature should only be at 120° to 125° F. 

If you prefer the steak to be medium-rare, then it must have 130° to 135° F internal temperature. One technique about getting it in the perfect temperature is to remove the meat 1 to 2 degrees early to your preferred doneness.

For example, if you want it to be medium-rare, remove it before it falls around 130 degrees Fahrenheit. The reason is that residual heat will cook the steak even further during the resting stage, thus reaching your preferred doneness temperature. Besides, resting gives the meat time  to redistribute the juices back to the entire meat strand, making it juicy and tender.

What Cut Of Meat Is Best Used For London Broil Recipe?

Flank steak has been referred to London broil and probably always will.

Throughout recent years, I have tried different cuts for making a London broil. The best one so far is the classic Flank steak. It’s easier to find and it’s affordable too.

You can find them in supermarkets, but for the best quality, always go to a local butcher shop whenever possible. They are labeled as either flank steak or London broil.

If all else fails, you can also go with a top blade or a top round cut. This is the best alternative I found in making a good London broil. It’s just as affordable (maybe even cheaper) and has good flavor too.

The difference is that it’s leaner so it may tend to dry up faster when not cook properly.

How To Cook The Most Tender London Broil: My Tips

• If you’re not planning to marinate the meat for more than two hours, you can just cover it with cling wrap and leave at room temperature. However, if you’re marinating it for more than 2 hours, make sure you put it in the fridge to avoid bacterial growth during the marinating process. Letting it chilled in  the fridge helps the meat strand to relax and soak up those nice and delicious flavors and aromas that  you want to infuse.

• If you left the steak marinated in the fridge for about 4 to 24 hours, take it out 10 minutes before you bake it and let it rest at room temperature.

• Sear the London broil on a screaming hot cast-iron skillet before baking to get the best flavor and color on it. Use a cast iron broiler pan and sear the steak for at least 30 to 45 seconds on each side before you put it in the oven.

• The searing process creates a lovely crust and caramelization between the beef and marinate. It also  seals the juices inside the meat to prevent it from leaking during the broiling process keeping it moist. Do not skip this step, it’s worth it!

• To make sure you get a tender London broil in every bite, cut the meat against the grain. Cutting or slicing it perpendicular to the fibers helps the strands become shorter, making it easier to chew and have a tender mouthfeel.

What To Serve With London Broil Steak?

My favorite side dish to serve with London broil is Roasted Potatoes in the oven. It’s quick and easy to make, and it goes perfectly well with the London broil.

Sometimes I throw in other veggies like carrots or asparagus too. It adds color and texture to the mix.

All you need to do is peel the potatoes and cut them in half. I prefer either Russet or Yukon potatoes when baking. If you’re planning to add veggies, save a little of the marinade on the side to soak them in.

Then transfer it to the baking pan or around the broil. Take them out after 20 to 30 minutes or until fork-tender while leaving the steak to continue cooking.

Serve on the side of your tender and juicy London broil. 😉
