What Is London Broil, Anyway?

Contrary to what many people think, London broil is not a specific cut of beef. Instead, it’s a cooking method that originated in London, where chefs would take tough, lean, inexpensive cuts of beef, marinate them to break down tough muscle fibers, then cook them quickly over high heat to get a crispy, caramelized exterior while keeping the inside juicy. The meat is then sliced thin against the grain to make it easy to chew, despite starting as a tough cut.

In the US, London broil is most commonly made with top round steak, flank steak, or sirloin tip steak. It’s a popular choice for budget-friendly meals, as these cuts are far less expensive than premium steaks like ribeye or filet, but when prepared correctly, they’re just as flavorful. Cooking London broil in the oven eliminates the need for a grill, making it accessible for anyone, no matter their kitchen setup.

Choosing the Right Cut of Meat for Oven London Broil

While you can use a few different cuts for oven London broil, some work better than others. Here are the best options to look for at your grocery store or butcher:

• Top round steak: The most common cut sold as pre-packaged “London broil,” top round is lean, affordable, and has a mild flavor that takes well to marinades. It’s a bit chewier than other cuts, but marinating and cooking it correctly will make it tender.
• Flank steak: Slightly fattier and more flavorful than top round, flank steak has a distinct grain that makes it easy to slice against. It cooks quickly, so watch it closely to avoid overcooking.
• Sirloin tip steak: A bit more tender than top round or flank, sirloin tip has a richer beef flavor and holds up well to high-heat cooking. It’s a great middle ground if you want tenderness without the premium price tag of a sirloin.
• Skirt steak: Very flavorful and tender when cooked correctly, skirt steak has a loose grain that makes it easy to slice. It’s thinner than other London broil cuts, so reduce cooking time by 1–2 minutes per side to avoid overcooking.

No matter which cut you choose, look for one that is 1.5 to 2 inches thick, with even marbling (small streaks of fat) throughout. Avoid cuts that are overly thin (less than 1 inch) or have large, hard chunks of fat or silver skin, as these will be difficult to cook evenly and can be chewy.

Essential Tools and Ingredients You’ll Need

Cooking perfect London broil in the oven requires just a few simple tools and ingredients, most of which you likely already have in your kitchen:

Tools

• Sharp chef’s knife
• Cutting board
• Large zip-top plastic bag or glass baking dish (for marinating)
• Instant-read meat thermometer (critical for perfect doneness)
• Aluminum foil
• Rimmed baking sheet
• Wire rack (optional, but recommended for even air circulation)
• Tongs

Ingredients

• 1.5–2 lb London broil cut (top round, flank, or sirloin tip, 1.5–2 inches thick)
• ¼ cup olive oil
• ¼ cup low-sodium soy sauce (or tamari for gluten-free)
• 2 tbsp Worcestershire sauce
• 2 tbsp fresh lemon juice or balsamic vinegar (acid helps tenderize the meat)
• 2 tbsp brown sugar or honey (optional, for balance)
• 3 cloves garlic, minced
• 1 tsp salt
• 1 tsp freshly ground black pepper
• 1 tsp dried rosemary
• 1 tsp dried thyme (or 1 tbsp fresh, chopped)

You can adjust the marinade to match your taste preferences: add a pinch of smoked paprika for a smoky flavor, a dash of red pepper flakes for heat, or a tablespoon of Dijon mustard for extra tang.

How to Prep London Broil for the Oven

Proper prep is the key to tender, flavorful London broil. Follow these steps to get your meat ready for the oven:

Trimming and Scoring the Meat

Start by placing the London broil on a cutting board. Use your sharp chef’s knife to trim off any large, hard chunks of fat or silver skin (the thin, silvery membrane on the surface of the meat), as these will be chewy and unpleasant to eat. Next, score the meat: make shallow, ¼-inch deep cuts in a crosshatch pattern on both sides of the steak. Don’t cut all the way through the meat—scoring helps the marinade penetrate deep into the muscle fibers, and also helps the meat cook more evenly.

Pro marinating tip: For the most tender results, marinate your London broil overnight in the refrigerator. The enzymes in the acidic marinade will break down tough muscle fibers without making the meat mushy, as long as you don’t exceed 24 hours of marinating time.

Making the Marinade

In a small bowl, whisk together the olive oil, soy sauce, Worcestershire sauce, lemon juice, brown sugar (if using), garlic, salt, pepper, rosemary, and thyme until the sugar is fully dissolved. The acid from the lemon juice and Worcestershire sauce will help tenderize the tough cut, while the soy sauce and herbs add deep, savory flavor.

Marinating Time Guidelines

Place the scored London broil in a large zip-top bag or glass baking dish, and pour the marinade over the top, turning to coat the meat fully on all sides. Seal the bag or cover the dish with plastic wrap, and marinate in the refrigerator for at least 2 hours, but ideally 4 to 8 hours, or overnight for the best results. Do not marinate for more than 24 hours, as the acid will break down the meat too much and leave it with a mushy texture. If you’re short on time, even 30 minutes of marinating is better than none, though the flavor and tenderness will be less pronounced.

Oven Settings and Cooking Times for London Broil

Broil vs. Bake: Which Is Better for London Broil?

When cooking London broil in the oven, you have two main options: broiling or baking. Broiling is the preferred method for most cooks, as it uses high, direct heat from the top of the oven to sear the outside of the meat quickly, creating a crispy, caramelized crust while keeping the inside juicy. Baking uses indirect, lower heat, which will cook the meat through but won’t give you the same crispy sear, so it’s a good backup if your oven’s broiler is broken or you prefer a softer texture.

For broiling, preheat your oven’s broiler to high (500°F / 260°C). Place the oven rack in the top third of the oven, so the meat is 3–4 inches from the broiler element, to get maximum heat for a good sear. For baking, preheat the oven to 400°F (200°C), and place the rack in the middle of the oven.

Cooking times will vary based on the thickness of your cut and your desired doneness, but as a general guideline for a 1.5-inch thick London broil:

• Broiling: 6–8 minutes per side for medium-rare, 8–10 minutes per side for medium
• Baking: 15–18 minutes per side for medium-rare, 20–22 minutes per side for medium

For cuts thinner than 1.5 inches, reduce cooking time by 1–2 minutes per side. For cuts thicker than 2 inches, add 1–2 minutes per side. Always use a meat thermometer to confirm doneness, as oven temperatures can vary.

Step-by-Step: How to Cook London Broil in the Oven

This step-by-step guide answers the question How to London Broil Oven? once and for all, with foolproof instructions for tender, juicy results every time:

1. Remove the marinated London broil from the refrigerator 30 minutes before cooking, and let it sit at room temperature. This helps the meat cook evenly, without cold spots in the center that lead to uneven doneness.
2. Preheat your oven’s broiler to high (500°F / 260°C). If you’re using a convection broil setting, you can use that for faster, more even cooking, but reduce cooking time by 1–2 minutes per side.
3. Line a rimmed baking sheet with aluminum foil for easy cleanup, and place a wire rack on top if you have one. The rack allows air to circulate around the meat, so you get a crispy sear on all sides, instead of a soft, steamed bottom. If you don’t have a wire rack, you can cook the meat directly on the foil-lined baking sheet.
4. Pat the marinated London broil completely dry with paper towels. Excess moisture on the surface of the meat will cause it to steam instead of sear, leading to a soft, bland crust. This step is critical for getting that signature crispy London broil exterior.
5. Brush the meat lightly with a small amount of extra olive oil, and season with a pinch of extra salt and pepper if desired, for extra flavor.
6. Place the London broil on the prepared baking sheet, and broil for 6–8 minutes per side for medium-rare, or 8–10 minutes per side for medium. Broiling can go from perfectly seared to burnt very quickly, so stay nearby and avoid walking away from the oven.
7. Halfway through cooking, flip the meat with tongs. If you want to use leftover marinade as a glaze, brush a small amount on top of the meat during the last 2 minutes of cooking. Note: Never use raw marinade that touched uncooked meat as a sauce unless you bring it to a rolling boil for 2 minutes first to kill harmful bacteria.
8. Check the internal temperature of the thickest part of the steak with a meat thermometer: 130°F (54°C) for medium-rare, 140°F (60°C) for medium, 150°F (65°C) for medium-well. Remember that the temperature will rise 5–10 degrees while the meat rests, so pull it off the broiler a few degrees before your target doneness to avoid overcooking.
9. Once the meat reaches your desired temperature, remove the baking sheet from the oven, and transfer the London broil to a clean cutting board.

How to Tell When London Broil Is Done

The most accurate way to check if your London broil is done is with an instant-read meat thermometer, as visual cues can be misleading, especially for new cooks. Insert the thermometer into the thickest part of the steak, avoiding any fat or bone, to get an accurate reading.

If you don’t have a meat thermometer, you can use the touch test: press the thickest part of the steak with your finger. Medium-rare steak will feel soft and springy, like the pad of your thumb when you touch your thumb to your pinky finger. Medium steak will feel slightly firmer, like touching your thumb to your ring finger. Medium-well steak will feel firm, like touching your thumb to your middle finger.

Keep in mind that London broil is best served medium-rare to medium. Because it is a very lean cut, cooking it past medium will cause it to dry out and become tough and chewy. Even if you prefer your steak well-done, it’s best to stop at medium-well for London broil to avoid a tough texture.

Resting, Slicing, and Serving Your London Broil

Many home cooks skip the resting step, but it’s one of the most important parts of cooking a perfect steak. After taking the London broil out of the oven, let it rest on the cutting board for 10–15 minutes, loosely tented with aluminum foil. This allows the juices that have been pulled to the surface of the meat during cooking to redistribute throughout the steak. If you slice it immediately, all those juices will run out onto the cutting board, leaving you with dry, bland meat.

Once the meat has rested, it’s time to slice. Always slice against the grain: the grain is the lines of muscle fiber running through the steak. Cutting against the grain shortens these fibers, making every bite tender, instead of chewy. Slice the meat thin, ¼ to ½ inch thick, for the best texture. If you’re having trouble slicing it thin, you can place the steak in the freezer for 15–20 minutes before slicing to firm it up.

London broil is incredibly versatile and works well with a wide range of sides and preparations. Serve it with roasted vegetables, mashed potatoes, or a fresh side salad for a classic dinner. Leftover London broil is perfect for sandwiches, tacos, stir-fries, or salads, and will keep in an airtight container in the refrigerator for up to 3 days.

Common Mistakes to Avoid When Cooking London Broil in the Oven

Even experienced cooks can make small errors that lead to tough, dry, or bland London broil. Avoid these common pitfalls to guarantee perfect results every time:

1. Overcooking the meat: London broil is a very lean cut, so it dries out quickly if cooked past medium. Always use a meat thermometer to pull it off the broiler 5 degrees before your target doneness, as the temperature will rise while resting.
2. Skipping the marinade or marinating for too short a time: Marinating is non-negotiable for tender London broil, as it breaks down tough muscle fibers and infuses flavor. Aim for at least 2 hours of marinating, up to 8 hours overnight, but never exceed 24 hours, as the acid will break down the meat too much and make it mushy.
3. Not scoring the meat: Scoring a crosshatch pattern into both sides of the meat helps the marinade penetrate deep into the fibers, so the entire steak is flavorful, not just the outside. Don’t skip this step.
4. Not patting the meat dry before cooking: Excess moisture on the surface of the meat will cause it to steam instead of sear, leading to a soft, bland crust instead of the crispy, caramelized exterior that makes London broil so delicious. Pat it thoroughly with paper towels before seasoning.
5. Slicing with the grain: The grain of the meat is the lines of muscle fiber running through the steak. Slicing with the grain leaves the fibers long and tough, while slicing against the grain shortens the fibers, making every bite tender. This is one of the easiest ways to improve the texture of your London broil.
6. Skipping the resting step: Letting the meat rest for 10–15 minutes after cooking allows the juices to redistribute throughout the steak. If you slice it immediately, all the juices will run out onto the cutting board, leaving you with dry meat.
7. Not preheating the broiler: The broiler needs to be fully preheated to high heat before you put the meat in, otherwise it will cook unevenly and won’t develop a proper sear. Wait until the oven is fully preheated before adding the steak.
8. Placing the rack too far from the heat source: For the best sear, place your oven rack in the top third of the oven, so the meat is close to the broiler element. If the rack is too low, the meat will cook through before developing a crispy crust.

Comparison: Oven London Broil vs. Grill London Broil

If you have access to a grill, you might be wondering if oven London broil is worth it, or if grilling is a better option. Here’s a breakdown of the key differences between the two methods:

As you can see, both methods have their perks. Oven London broil is ideal for convenience and consistency, while grilling adds a smoky, charred flavor that many people love. If you have the time and access to a grill, try both to see which you prefer!

Pro Tips for Perfect Oven London Broil Every Time

Take your oven London broil to the next level with these expert tips:

• Always use an instant-read meat thermometer: it’s the only way to guarantee perfect doneness, no guesswork required.
• For extra crispy crust, broil for the last 1–2 minutes with the oven door slightly ajar (check your oven’s manual first, as some manufacturers do not recommend this, but it improves air circulation and browning).
• If you want an even thicker, crispier sear, sear the marinated London broil in a hot cast-iron skillet on the stovetop for 1 minute per side before transferring it to the oven under the broiler.
• Don’t overcrowd the baking sheet: if you’re cooking multiple pieces of meat, leave 1–2 inches of space between them so air can circulate, and they sear properly instead of steaming.
• Leftover London broil freezes well for up to 2 months: store sliced meat in an airtight container or freezer bag, and thaw in the refrigerator before reheating gently to avoid drying it out.

Frequently Asked Questions

Here are answers to the most common questions about cooking London broil in the oven:

Can I cook London broil in the oven without marinating?

Yes, but it will be significantly tougher and less flavorful than marinated meat. Marinating is the key step that tenderizes the lean cut and infuses it with savory flavor. If you’re short on time, you can brush the meat with a mixture of olive oil, soy sauce, minced garlic, and a pinch of salt and pepper, and let it sit at room temperature for 30 minutes while you preheat the oven. This won’t be as good as a full marinade, but it’s better than cooking it plain.

What temperature should I cook London broil at in the oven?

For broiling, preheat your oven to 500°F (260°C) high, with the rack in the top third of the oven. For baking, preheat to 400°F (200°C), with the rack in the middle of the oven. Broiling is recommended for the best sear and flavor.

How long does it take to cook London broil in the oven?

For a 1.5-inch thick cut, it takes 6–8 minutes per side for medium-rare, and 8–10 minutes per side for medium, when broiling at 500°F. Thinner cuts cook faster, while thicker cuts take longer. Always use a meat thermometer to confirm doneness, as oven temperatures can vary.

Can I cook frozen London broil in the oven?

It’s not recommended. Frozen meat cooks unevenly, and you won’t be able to get a good sear on the outside while the inside is still frozen. Thaw the meat in the refrigerator overnight first for the best results. If you’re in a hurry, you can thaw it in the microwave using the defrost setting, but this can affect the texture slightly.

Why is my London broil tough?

The most common reasons for tough London broil are overcooking, not marinating long enough, or slicing with the grain. London broil is a lean cut, so it needs to be cooked to no more than medium to avoid drying out. Marinating for at least 2 hours breaks down tough muscle fibers, and slicing against the grain shortens the fibers to make the meat more tender.

Can I use the leftover marinade as a sauce?

Only if you bring it to a rolling boil in a small saucepan for at least 2 minutes first. Raw marinade that has come into contact with uncooked meat can contain harmful bacteria like E. coli or Salmonella, so you must cook it thoroughly to kill any pathogens before using it as a sauce or glaze. Never use raw leftover marinade directly on cooked meat or as a dipping sauce.

Conclusion

Cooking London broil in the oven is a simple, affordable, and delicious way to make a restaurant-quality meal at home, no grill required. By following the steps in this guide—choosing the right cut, marinating it properly, cooking it to the correct doneness, and slicing it against the grain—you’ll get tender, juicy, flavorful London broil every single time. Whether you’re making a quick weeknight dinner or hosting a dinner party, this versatile dish is sure to be a hit with your family and friends.
