What Exactly Is London Broil?

One of the most common points of confusion around London broil is that it’s not actually a specific cut of beef – it’s a preparation method. The term originated in 19th century London, where broiling houses would slice tough, lean cuts of beef thin, marinate them to tenderize the meat, and cook them over high heat for a quick, flavorful meal. Today, when you see “London broil” labeled at the grocery store, it almost always refers to a cut of top round steak, though flank steak and sirloin tip are also commonly used for this preparation.

The key trait of any cut used for London broil is that it’s lean, with minimal marbling (intramuscular fat). While this makes it a budget-friendly, low-fat option, it also means it can become tough and dry if overcooked or prepared incorrectly. That’s why the marinade and controlled cooking method we’ll cover later are so important for getting tender results. Many pre-packaged London broil cuts come pre-marinated, but making your own marinade is far more flavorful and lets you control the sodium and ingredient quality.

Can You Cook London Broil in the Oven? The Short Answer

To answer the core question directly: Yes, you can absolutely cook London broil in the oven, and it’s one of the most reliable methods for home cooks. Unlike grilling, which can have hot spots, flare-ups, and weather limitations, the oven provides consistent, even heat that lets you cook the meat evenly without burning the exterior before the interior is done. This is especially helpful for London broil, which is a lean cut that dries out quickly if cooked at too high a heat for too long.

The oven method also works well for meal prep, as you can cook multiple cuts at once and store leftovers for up to 4 days in the refrigerator. Many people assume London broil is only for summer grilling, but the oven version is just as flavorful, and often more tender, thanks to the ability to control the internal temperature precisely. If you’ve ever had a tough, chewy piece of London broil off the grill, the oven method will likely become your new go-to.

Oven vs. Grill: Which Is Better for London Broil?

While grilling is the traditional way to cook London broil, the oven has plenty of perks that make it a better choice for many home cooks. Let’s break down the key differences between the two methods to help you decide which works best for your needs.

If you’re still wondering Can You Cook London Broil in the Oven for special occasions? Absolutely – the consistent results make it perfect for dinner parties where you don’t want to risk a tough cut of meat for guests. That said, if you love that classic smoky char, you can add a sprinkle of smoked paprika to your marinade, or finish the cooked meat under the broiler for 1 minute to get a light char without the hassle of grilling.

Choosing the Right Cut of London Broil for Oven Cooking

While London broil is a preparation method, the cut of meat you buy will have a huge impact on the final tenderness and flavor. Not all cuts labeled “London broil” are created equal, so keep these tips in mind when shopping:

• Top Round Steak: The most common and affordable cut labeled London broil, it’s very lean, so it benefits the most from marinating and precise cooking. Look for cuts that are 1 to 1.5 inches thick, with minimal tough connective tissue.
• Flank Steak: Slightly more expensive than top round, but more flavorful and with a bit more natural marbling. It’s very tender when sliced against the grain, making it a great choice for oven cooking.
• Sirloin Tip: A bit more tender than top round, with less lean texture, so it’s less likely to dry out if you accidentally overcook it slightly.

Avoid cuts that are marketed as “London broil” but are actually chuck roast or other tough, slow-cooking cuts, as these will be chewy even when marinated and cooked in the oven. If you can’t find a pre-labeled London broil cut, ask your butcher for a 1-inch thick top round steak, which is the standard cut used for this preparation. Look for cuts with small streaks of fat throughout, as this will help keep the meat juicy during cooking.

Essential Tools and Ingredients You’ll Need

Tools

• Heavy oven-safe skillet (cast iron is best for searing, as it retains heat well)
• Instant-read meat thermometer (critical for avoiding overcooking)
• Sharp carving knife and stable cutting board
• Mixing bowl for marinade
• Aluminum foil for resting the meat
• Zip-top plastic bag or shallow glass dish for marinating

Ingredients

• 1.5–2 lbs London broil cut (top round, flank, or sirloin tip, 1–1.5 inches thick)
• ½ cup low-sodium soy sauce (or tamari for gluten-free)
• ¼ cup olive oil or avocado oil
• 3 tbsp acid (balsamic vinegar, red wine vinegar, or fresh lemon juice)
• 3 garlic cloves, finely minced
• 1 tbsp fresh herbs (rosemary, thyme, or oregano, or 1 tsp dried herbs)
• 1 tsp freshly ground black pepper
• Optional add-ins: 1 tsp smoked paprika, 1 tbsp brown sugar, ½ tsp red pepper flakes, 1 tbsp Worcestershire sauce, 1 tbsp Dijon mustard

Step 1: Prep and Marinate Your London Broil

Marinating is the single most important step for tender London broil, as the acid and salt in the marinade break down tough muscle fibers and infuse the meat with flavor. Without marinating, even perfectly cooked London broil will be chewy and bland. Here’s how to prep it correctly:

1. Remove the London broil from its packaging and pat it completely dry with paper towels. Excess moisture on the surface of the meat will prevent the marinade from sticking and lead to a soggy sear later.
2. In a medium mixing bowl, whisk together all marinade ingredients until fully combined.
3. Place the dried London broil in a large zip-top bag or shallow glass dish, and pour the marinade over it. Turn the meat to make sure it’s fully coated on all sides.
4. Seal the bag or cover the dish with plastic wrap, and refrigerate for at least 2 hours, up to 24 hours. Don’t marinate for longer than 24 hours, as the acid will start to break down the meat’s structure too much, leading to a mushy texture. If you’re short on time, you can marinate at room temperature for 30 minutes, but the longer marinating time will yield more tender results.
5. If you’re using a zip-top bag, squeeze all excess air out before sealing to ensure the marinade coats the meat evenly.

Pro tip: If you don’t have time to marinate, you can use a meat tenderizer to poke small holes in the meat before cooking, and rub it with a mixture of 1 tsp baking soda and 1 tsp salt 30 minutes before cooking. The baking soda raises the meat’s pH level, which helps break down tough fibers, but be sure to rinse it off before cooking to avoid a soapy taste.

Step 2: Sear the London Broil for Maximum Flavor

Searing the meat before roasting creates a deep, caramelized crust that adds layers of flavor you can’t get from roasting alone. It also helps lock in juices, leading to a more tender final product. Follow these steps for a perfect sear:

1. Preheat your oven-safe skillet over medium-high heat on the stovetop. Cast iron works best, as it retains heat evenly and gets very hot without warping.
2. Add 1 tsp of oil to the skillet, and let it heat until it shimmers (but not smokes, as this will burn the oil).
3. Remove the London broil from the marinade, letting excess liquid drip off, and pat it dry one more time with paper towels. Season both sides lightly with a pinch of salt and pepper.
4. Place the meat in the hot skillet, and don’t move it for 3–4 minutes. You want a deep golden brown crust to form on the bottom before flipping. If you try to flip it too early, the crust will stick and tear.
5. Flip the meat and sear the other side for 2–3 minutes, until a crust forms. If your skillet is small, you can sear the meat in batches to avoid overcrowding, which will steam the meat instead of searing it.

Pro tip: For extra flavor, add ¼ cup of red wine or beef broth to the skillet after searing, and use a wooden spoon to scrape up any browned bits from the bottom of the pan. Pour this liquid into your roasting pan later for added depth of flavor.

Step 3: Roast to Perfect Doneness in the Oven

Once your London broil is seared on both sides, it’s time to finish cooking it in the oven. The key here is to avoid overcooking, as London broil is a lean cut that dries out quickly when cooked past medium. Follow these steps:

1. Preheat your oven to 400°F (200°C) while you’re searing the meat.
2. Once the meat is seared on both sides, pop the skillet directly into the preheated oven (if using a regular non-oven-safe skillet, transfer the seared meat to a roasting pan first).
3. Roast for 10–18 minutes, depending on the thickness of the meat and your desired doneness. Use the following guide as a reference, but always rely on a meat thermometer for accuracy:

• Rare: 120–125°F internal temperature, 10–12 minutes total cook time
• Medium Rare: 130–135°F, 13–15 minutes (recommended for maximum tenderness)
• Medium: 140–145°F, 16–18 minutes
• Well Done: 150°F+, 19+ minutes (not recommended, as the meat will be tough and dry)

Insert the meat thermometer into the thickest part of the cut, making sure not to touch bone or fat, which will give you an inaccurate reading. Remember that the meat’s internal temperature will rise 5–10°F while it rests, so pull it out of the oven 5°F below your target temperature. If you prefer a more charred crust, you can turn on the broiler for the last 1–2 minutes of cooking, but watch it closely to avoid burning.

Step 4: Rest and Slice for Tender Results

Resting the meat after cooking is a non-negotiable step that most home cooks skip, but it makes the difference between juicy, tender London broil and dry, tough meat. When you cook meat, the juices contract and move to the center of the cut. If you slice it immediately after taking it out of the oven, all those juices will run out onto the cutting board, leaving you with dry meat. Here’s how to do it right:

1. Once the meat reaches your desired internal temperature, take the skillet out of the oven and transfer the London broil to a clean cutting board.
2. Tent the meat loosely with aluminum foil (don’t wrap it tightly, as this will steam the crust and make it soggy) and let it rest for 10–15 minutes.
3. After resting, use a very sharp carving knife to slice the meat against the grain (perpendicular to the direction of the long muscle fibers) into ¼-inch thick slices. Slicing against the grain shortens the tough muscle fibers, making every bite tender, even if you cooked the meat a little longer than ideal.

Pro tip: For sandwiches or tacos, slice the meat even thinner (⅛-inch thick) for a more tender texture. For main dishes, ¼-inch slices are perfect. Always use a sharp knife – a dull knife will tear the meat instead of cutting cleanly, making it feel tougher.

Common Mistakes to Avoid When Cooking London Broil in the Oven

Even experienced home cooks can make these common errors when cooking London broil in the oven. Avoid them to get perfect results every time:

• Skipping the marinade: London broil is a lean, tough cut, so marinating is essential to break down muscle fibers and add flavor. Without it, the meat will be chewy and bland, no matter how well you cook it.
• Overcooking the meat: Because it’s lean, London broil dries out quickly when cooked past medium. Always use a meat thermometer, and pull it out 5°F below your target temperature, since it will continue to cook while resting.
• Slicing with the grain: This leaves long, tough muscle fibers in each bite, making even perfectly cooked meat feel chewy. Always slice against the grain for maximum tenderness.
• Skipping the sear: Roasting alone will give you bland, gray meat with no crispy crust. The 5-minute stovetop sear adds tons of flavor and texture that you can’t get from the oven alone.
• Not patting the meat dry before searing: Excess moisture on the surface of the meat will steam it instead of searing it, leading to no crust and a soggy texture.
• Forgetting to let the meat rest: Cutting into the meat immediately after taking it out of the oven will cause all the juices to run out, leaving you with dry, tough meat. Always let it rest for at least 10 minutes.

Frequently Asked Questions

Can You Cook London Broil in the Oven Without a Cast Iron Skillet?

Yes! If you don’t have an oven-safe skillet, you can sear the London broil in a regular non-oven-safe skillet on the stovetop, then transfer it to a roasting pan to finish in the oven. Just make sure to get a good sear on all sides before transferring to lock in flavor.

How Long Does It Take to Cook London Broil in the Oven at 400°F?

Total cook time (searing + roasting) is 25–35 minutes for a 1.5–2 lb cut that’s 1 inch thick. Roasting time alone is 10–18 minutes, depending on your desired doneness. Always use a meat thermometer for accuracy, as cook time can vary based on the thickness of the cut and your oven’s temperature.

Can You Cook Frozen London Broil in the Oven?

It’s not recommended to cook frozen London broil directly in the oven, as it will cook unevenly and be tough. Thaw it in the refrigerator for 24 hours first, then marinate and cook as directed. If you’re in a hurry, you can thaw it in the microwave using the defrost setting, but pat it very dry before marinating to avoid excess moisture that will prevent a good sear.

What Temperature Should I Cook London Broil to in the Oven?

For the best tenderness, cook London broil to an internal temperature of 130–135°F for medium-rare, or 140–145°F for medium. Remember that the temperature will rise 5–10°F while the meat rests, so pull it out of the oven 5°F below your target temperature.

Can I Cook London Broil in the Oven at a Lower Temperature?

Yes, you can cook it at 325°F for a slower, more even cook, but you’ll need to increase the total cook time by 10–15 minutes. This method is great if you’re cooking multiple cuts at once, or if you want extra tender results. Just make sure to still sear it first for flavor, and use a meat thermometer to check for doneness.

Is London Broil in the Oven Healthy?

Yes! London broil is a lean cut of beef, high in protein, iron, and B vitamins. When cooked without excess oil or heavy sauces, it’s a healthy, low-fat option for a weeknight meal.
