How to Cook London Broil in the Oven: Easy Guide & Tips

London broil is a popular cooking method and a dish that features marinated flank steak, known for its rich flavor and hearty texture. Despite its name, London broil is not a specific cut of meat but rather a method of preparation that typically involves marinating a tougher cut, such as flank steak or top round, and then grilling or broiling it to perfection.

The key to a successful London broil lies in the marinating process, which tenderizes the meat and infuses it with flavors from various ingredients, such as soy sauce, garlic, and herbs. Once marinated, the steak is cooked quickly over high heat to achieve a beautifully charred exterior while retaining a juicy interior. After cooking, it’s sliced against the grain, ensuring each bite is tender and flavorful.

London broil is often served with sides like roasted vegetables, mashed potatoes, or a fresh salad, making it a versatile dish for family dinners, gatherings, or special occasions. Its simplicity and robust taste have made it a favorite among home cooks and grill enthusiasts alike.

Choosing the Right Cut of Meat for London Broil

Selecting the right cut of meat is essential for achieving a delicious and tender London broil. Here are some key cuts to consider, along with tips to ensure you make the best choice:

1. Flank Steak

Flank steak is the most common cut used for London broil. It comes from the abdominal muscles of the cow, offering a rich flavor and slightly chewy texture. Its leanness makes it ideal for marinating, which helps to tenderize the meat. When cooked properly and sliced against the grain, flank steak delivers a satisfying chew.

2. Top Round Steak

Top round is another excellent choice for London broil. This cut comes from the rear leg of the cow and is slightly more tender than flank steak, with a mild flavor. Like flank steak, top round benefits from marinating to enhance its tenderness and taste. It’s a great option if you’re looking for a more affordable cut that still delivers good flavor.

3. Skirt Steak

Skirt steak is a flavorful cut that comes from the diaphragm of the cow. It has a loose grain and a higher fat content, which adds to its richness. While not as commonly used as flank or top round for London broil, skirt steak can yield fantastic results when marinated and grilled. It’s essential to slice it against the grain for the best texture.

4. Sirloin Steak

Although less traditional, sirloin steak can also be used for London broil. It offers a good balance of flavor and tenderness, making it suitable for marinating and grilling. If you choose sirloin, look for the top sirloin, as it tends to be more tender than the bottom sirloin.

Tips for Choosing the Best Cut:

  • Look for Marbling: Choose cuts with some marbling (intramuscular fat), which helps keep the meat moist during cooking.
  • Freshness Matters: Always select fresh, high-quality meat from a reputable butcher or grocery store. Look for bright color and avoid any cuts that appear dull or have excessive browning.
  • Consider Thickness: For London broil, aim for steaks that are about 1 to 1.5 inches thick. This thickness allows for a good sear while ensuring the inside remains juicy.

By choosing the right cut of meat and preparing it properly, you can create a delicious London broil that’s sure to impress!

Preparing London Broil for Cooking

Preparing London broil involves a few essential steps to ensure that the meat is flavorful and tender. Here’s how to get your flank or top round steak ready for cooking:

1. Marinate the Meat

Marinating is key to enhancing the flavor and tenderness of London broil. Here’s how to do it:

  • Choose a Marinade: Select a marinade that includes acidic components (like vinegar or citrus juice) to help tenderize the meat, along with flavorful ingredients such as soy sauce, garlic, onion, herbs, and spices. Here’s a simple marinade recipe:
    • 1/2 cup soy sauce
    • 1/4 cup olive oil
    • 2 tablespoons red wine vinegar or balsamic vinegar
    • 3 cloves garlic, minced
    • 1 tablespoon Worcestershire sauce
    • Freshly ground black pepper to taste
  • Combine Ingredients: Whisk together the marinade ingredients in a bowl or jar.
  • Marinate the Steak: Place the meat in a resealable plastic bag or a shallow dish and pour the marinade over it. Seal the bag or cover the dish, ensuring the steak is well coated. Marinate in the refrigerator for at least 4 hours, preferably overnight for maximum flavor.

2. Bring to Room Temperature

Before cooking, remove the marinated steak from the refrigerator and allow it to sit at room temperature for about 30 minutes. This helps the meat cook more evenly.

3. Preheat the Grill or Broiler

Whether you’re grilling or broiling, preheating is crucial:

  • For Grilling: Preheat your grill to medium-high heat (about 400°F to 450°F).
  • For Broiling: Set your oven’s broiler to high and position the oven rack about 4-6 inches from the heat source.

4. Remove Excess Marinade

After marinating, take the steak out of the marinade and let any excess liquid drip off. You can pat the steak dry with paper towels to remove moisture, which helps achieve a good sear.

5. Season the Steak (Optional)

While the marinade adds flavor, you can enhance it further by sprinkling a little salt and pepper on both sides of the steak just before cooking.

6. Prepare for Cooking

If grilling, oil the grill grates lightly to prevent sticking. If broiling, place the steak on a broiler pan or a baking sheet lined with aluminum foil for easy cleanup.

By following these preparation steps, you’ll set the stage for a flavorful and tender London broil that’s perfect for grilling or broiling. Enjoy the process and get ready for a delicious meal!

Cooking Methods for London Broil in the Oven

Cooking London broil in the oven is a convenient and effective way to achieve a tender and flavorful dish. The two primary methods for oven cooking are broiling and roasting. Here’s how to do each:

1. Broiling London Broil

Broiling is a quick cooking method that uses high heat from above, making it ideal for getting a nice sear on the outside while keeping the inside juicy. Here’s how to do it:

Instructions:

  1. Preheat the Broiler: Set your oven’s broiler to high and position the rack about 4-6 inches from the heat source.
  2. Prepare the Meat: Follow the preparation steps outlined earlier, ensuring the meat is well-marinated and at room temperature.
  3. Place the Steak on a Broiler Pan: Use a broiler pan to allow grease to drip away during cooking. If you don’t have a broiler pan, a baking sheet lined with aluminum foil can also work.
  4. Broil the Steak: Place the steak in the preheated oven. Broil for about 6–8 minutes on the first side, depending on the thickness of the meat. Avoid opening the oven door too often, as this can lower the temperature.
  5. Flip and Continue Cooking: After the first side is nicely browned, flip the steak and broil for another 6–8 minutes. For medium-rare, aim for an internal temperature of about 135°F (57°C).
  6. Rest the Meat: Once cooked to your desired doneness, remove the steak from the oven and let it rest for about 5–10 minutes. This allows the juices to redistribute for a more tender bite.
  7. Slice and Serve: Slice the steak against the grain into thin strips and serve with your favorite sides.

2. Roasting London Broil

Roasting is a slower cooking method that cooks the meat more evenly throughout, resulting in a tender and flavorful steak. Here’s how to roast a London broil:

Instructions:

  1. Preheat the Oven: Preheat your oven to 400°F (200°C).
  2. Prepare the Meat: As with broiling, marinate the steak and allow it to come to room temperature.
  3. Place in a Baking Dish: Transfer the marinated steak to a roasting pan or a rimmed baking sheet. If you like, you can add vegetables (like carrots, potatoes, or onions) around the steak for a complete meal.
  4. Roast the Steak: Roast in the preheated oven for about 20–30 minutes, depending on the thickness of the meat. Use a meat thermometer to check the internal temperature: 135°F (57°C) for medium-rare and 145°F (63°C) for medium.
  5. Rest the Meat: Once the steak reaches your desired temperature, remove it from the oven and let it rest for 5–10 minutes to allow the juices to settle.
  6. Slice and Serve: Slice the steak against the grain into thin strips and serve with your favorite sides.

Both cooking methods yield delicious results, so you can choose based on your preference for a quick sear or a slower, more even cook.

Resting and Slicing London Broil

Resting and slicing London broil correctly are crucial steps to ensure the meat remains tender and flavorful. Here’s how to do it right:

1. Resting the London Broil

After cooking your London broil, resting is essential to allow the juices to redistribute throughout the meat, enhancing its flavor and tenderness.

  • Remove from Heat: Once the steak reaches your desired doneness, take it out of the oven or off the grill.
  • Cover Loosely: Tent the steak with aluminum foil. This helps keep it warm while preventing it from steaming and losing its crust.
  • Resting Time: Allow the steak to rest for about 5–10 minutes. This time lets the juices settle, reducing the amount that runs out when you slice the meat.

2. Slicing the London Broil

Slicing your London broil properly is vital for maximizing tenderness and flavor. Follow these steps for the best results:

  • Use a Sharp Knife: A sharp knife is essential for clean cuts. A chef’s knife or a carving knife works well for this purpose.
  • Identify the Grain: Look at the meat to identify the direction of the grain (the lines running through the meat). Slicing against the grain shortens the muscle fibers, making each bite more tender.
  • Slice Thinly: Position the steak on a cutting board and slice it into thin strips, about 1/4 inch thick. If you have a thicker cut, you may want to cut it into thicker slices first and then slice those against the grain.
  • Angle Your Cuts: For a more elegant presentation, you can slice at a slight angle (bias slicing), which can help create larger surface areas for flavor.

3. Serving the Sliced London Broil

  • Plate and Garnish: Arrange the sliced meat on a serving platter. You can garnish with fresh herbs like parsley or chives for an appealing touch.
  • Accompany with Sides: Serve with your choice of sides, such as roasted vegetables, mashed potatoes, or a fresh salad, to complete the meal.

By following these steps for resting and slicing, you can enjoy a perfectly cooked London broil that is juicy, tender, and bursting with flavor. Enjoy your delicious meal!
