What Is London Broil

The internal temperature should reach 135 degrees Fahrenheit for a perfectly cooked London Broil. I suggest using a meat thermometer to monitor the temperature throughout the cooking process. You can aim for a slightly lower internal temperature if you prefer a pinker center.

To prevent the meat from drying out, it’s a good idea to baste it with wet ingredients while cooking at a lower temperature. This will help retain moisture and ensure a juicy and flavorful result.

Cooking times can vary, but as a general guideline, it typically takes about 6-8 minutes per side at 350 degrees Fahrenheit for a medium-rare London Broil. However, I recommend flipping the meat at the 7-minute and checking for doneness at 14 minutes. Adjust the cooking time according to your preference and the thickness of the meat.

How Long Should You Marinate A London Broil Before Cooking It In The Oven?

How Long Should You Marinate A London Broil Before Cooking It In The Oven

Marinating a London broil before cooking it in the oven can greatly enhance its flavor and tenderness. The key is to allow enough time for the marinade to penetrate the meat and work its magic. Generally, I recommend marinating a London broil for at least 4 hours, but it can be marinated for up to 2 days for even better results. During this time, I occasionally toss the meat in the marinade to ensure it is evenly coated.

Before cooking, I remove the meat from the marinade, discard it, and pat it dry to achieve better browning and searing. This technique results in a juicy and flavorful London broil that will impress your guests.

What Is The Ideal Thickness Of The London Broil For Cooking In The Oven At 350 Degrees?

I can say that the ideal thickness of the London broil for cooking in the oven at 350 degrees Fahrenheit is about 1 inch. This thickness allows even cooking and ensures the meat remains juicy and tender. Cooking times may vary depending on factors such as marinade and specific oven, but a general rule of thumb is to cook the meat for 10-15 minutes per inch of thickness. To ensure proper doneness, I always recommend using a meat thermometer.

Some Great Marinade Options For Enhancing The Flavor Of The London Broil

When it comes to marinating a London broil, the options are endless. The key is to choose a marinade that complements the meat’s natural flavors while adding a delicious depth of flavor. Here are a few of my go-to marinade options that never fail to impress:

  1. Classic Red Wine Marinade: There’s something timeless about a classic red wine marinade. The wine’s tannins help tenderize the meat while infusing it with rich, complex flavors. To create this marinade, combine red wine, minced garlic, fresh rosemary, olive oil, salt, and pepper. Let the London broil marinate for at least 4 hours or overnight for maximum flavor.
  2. Asian-inspired Soy Ginger Marinade: If you’re in the mood for a fusion of flavors, this soy ginger marinade is a winner. Mix together soy sauce, fresh ginger, minced garlic, sesame oil, honey, and a splash of rice vinegar. The soy sauce adds a savory umami taste, while the ginger adds a subtle kick. Marinate the London broil for at least 2 hours or overnight for a bolder flavor.
  3. Zesty Citrus Marinade: Try a zesty citrus marinade for a refreshing and tangy twist on the London broil. Combine freshly squeezed lemon and orange juice, minced garlic, Dijon mustard, honey, and a pinch of red pepper flakes. The citrus juices not only add a bright flavor but they also help to tenderize the meat. Let the London broil marinate for at least 3 hours or overnight for a burst of citrusy goodness.

  1. Choose the right cut: The key to a perfectly cooked London Broil starts with selecting the right cut of meat. Look for a well-marbled piece of top round or flank steak. These cuts are known for their tenderness and ability to absorb flavors during cooking.
  2. Marinate for flavor: Marinating the London Broil is crucial for infusing it with delicious flavors. Prepare a marinade using soy sauce, Worcestershire sauce, garlic, herbs, and spices. Place the steak in a zip-lock bag and pour the marinade over it. Allow it to marinate in the refrigerator for at least 4 hours, preferably overnight, to maximize the flavor.
  3. Preheat the oven: Preheating the oven is essential to ensure even cooking. Set the oven to 400°F (200°C) and allow it to reach the desired temperature before placing the London Broil inside.
  4. Sear for a perfect crust: Searing it in a hot skillet or cast-iron pan to achieve a delightful crust on your London Broil. Heat some oil in the pan and sear the steak for 2-3 minutes on each side until a golden brown crust forms. This step not only enhances the flavor but also helps to seal the juices.
  5. Transfer to the oven: After searing, transfer the London Broil to a baking dish or a wire rack set on top of a baking sheet. Place it in the preheated oven and cook for 10-15 minutes per pound. This will give you a medium-rare steak. Adjust the cooking time according to your desired level of doneness.

Prep time


Cooking time






  • 1 (2 pound) top round London broil

  • 1 (28 ounce) can stewed tomatoes

  • 1 teaspoon garlic salt, or to taste


  • Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This temperature is ideal for slow roasting the meat, allowing it to become tender and juicy while retaining its natural flavors. Once the oven is preheated, it’s time to get cooking!
  • Place your London broil in a roasting pan, making sure it fits comfortably without overcrowding. This will ensure even cooking and optimal results. Pour a can of stewed tomatoes over the meat, allowing the flavorful juices to infuse into the beef. To enhance the taste, sprinkle the London broil with a generous amount of garlic salt, adding a savory kick to every bite.
  • With your seasoned London broil in the roasting pan, it’s time to let the oven work its magic. Roast the meat in the oven for approximately 2 ½ to 3 hours. This slow-cooking method allows the collagen in the meat to break down, resulting in a fork-tender texture that melts in your mouth. You’ll know it’s done when the meat is easily pierced with a fork and pulls apart effortlessly.
  • Once the cooking time is complete, remove the roasting pan from the oven, but don’t rush to carve the meat just yet. It’s important to let the London broil rest for about 10 minutes before slicing. This resting period allows the juices to be redistributed, ensuring a moist and flavorful final product.
  • Finally, it’s time to carve and serve your perfectly cooked London broil. Slice the meat against the grain, which will help maintain its tenderness. It’s entirely up to you whether you prefer thicker or thinner slices. Pair your succulent London broil with your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad, for a complete and satisfying meal.
