By Michael Ferguson

If you’re in the mood for a delicious and flavorful steak, London broil is the way to go. This lean cut of beef is perfect for grilling or broiling, but if you’re looking to bake it in the oven, you may be wondering how long to leave it in there. In this guide, we’ll go over the steps for baking a London broil and how long it should stay in the oven.

First things first, let’s talk about what exactly a London broil is. Despite its name, this cut of beef does not actually come from London.

It’s a method of preparing flank steak that involves marinating it and then grilling or broiling it quickly on high heat. The result is a juicy and flavorful steak that’s perfect for slicing thin and serving with your favorite sides.

To bake a London broil in the oven, you’ll need to start by preheating your oven to 400°F (205°C). While the oven is heating up, prepare your marinade or seasoning rub. You can use any marinade or seasoning blend that you like, but some popular options include soy sauce, Worcestershire sauce, garlic powder, onion powder, salt and pepper.

Once your marinade or seasoning blend is ready, place your London broil in a shallow baking dish and pour the marinade over it. Use your hands or a brush to make sure that all sides of the steak are coated evenly.

Next, cover the baking dish with foil and place it in the preheated oven. The general rule of thumb for cooking a London broil in the oven is about 15 minutes per pound (454 grams) of meat for medium-rare doneness. So if you have a 2-pound (907-gram) London broil, you’ll want to bake it for about 30 minutes.

After 30 minutes have passed, remove the foil from the baking dish and use a meat thermometer to check the internal temperature of the steak. For medium-rare doneness, the temperature should be between 135-140°F (57-60°C). If it’s not quite there yet, return the steak to the oven and continue baking it for a few more minutes.

Once your London broil has reached your desired level of doneness, remove it from the oven and let it rest for about 5-10 minutes. This will allow the juices to redistribute throughout the meat and make it even more tender and flavorful.

Finally, slice your London broil against the grain into thin strips and serve with your favorite sides. Some popular options include roasted vegetables, mashed potatoes, or a simple salad.

In conclusion, baking a London broil in the oven is a simple and delicious way to prepare this flavorful cut of beef. By following these steps and keeping an eye on cooking times and internal temperatures, you’ll have a juicy and tender steak that’s sure to impress your taste buds.
