Finishing the marinated beef under the broiler after a quick sear creates a caramelized crust while keeping the inside tender. If you have been wondering how to cook london broil oven style, you are in the right place. This method is simple, reliable, and delivers a restaurant-quality meal at home.
London broil is not actually a cut of meat—it is a cooking technique. Most often, it refers to a thick cut from the top round or flank steak. The key is to cook it quickly at high heat and slice it thinly against the grain. The oven broiler does this perfectly.
In this guide, you will learn the exact steps, timing, and tricks to get a juicy, flavorful London broil every time. No more dry or tough meat. Let us get started.
What Is London Broil?
Before we dive into the cooking process, it helps to understand what you are working with. London broil is a lean cut of beef, usually from the top round or flank. It is tough if not cooked correctly. The high heat of the broiler breaks down connective tissues quickly.
Because it is lean, marinating is essential. A good marinade adds flavor and helps tenderize the meat. The oven broiler method gives you a nice crust on the outside while keeping the inside medium-rare to medium.
Why Use The Oven For London Broil?
Many people grill London broil, but the oven broiler offers more control. You do not need to worry about weather or flare-ups. The heat comes from above, directly browning the surface. This mimics the effect of a grill but indoors.
Using the oven also allows you to finish the meat evenly. You can sear it on the stovetop first, then move it under the broiler. This two-step method gives you the best of both worlds: a crusty exterior and a tender interior.
How To Cook London Broil Oven: Step-By-Step Guide
Now, let us get to the main event. Follow these steps carefully, and you will have a perfect London broil every time.
Step 1: Choose The Right Cut
Start with a good piece of meat. Look for a top round or flank steak that is about 1.5 to 2 inches thick. Thicker cuts work better for the broiler because they have more time to cook without burning on the outside.
- Ask your butcher for a London broil cut, usually top round.
- Look for even thickness so it cooks uniformly.
- Avoid cuts that are too thin—they will dry out quickly.
Step 2: Marinate The Meat
Marinating is not optional. It adds flavor and tenderizes the lean meat. You need at least 2 hours, but overnight is best. Here is a simple marinade recipe.
- 1/2 cup soy sauce
- 1/4 cup olive oil
- 2 tablespoons red wine vinegar
- 3 cloves garlic, minced
- 1 tablespoon brown sugar
- 1 teaspoon black pepper
Combine all ingredients in a bowl. Place the meat in a zip-top bag and pour the marinade over it. Seal the bag, remove air, and refrigerate. Turn the bag occasionally to coat evenly.
Step 3: Preheat The Oven And Broiler
About 30 minutes before cooking, take the meat out of the fridge. Let it sit at room temperature. This helps it cook more evenly. Meanwhile, preheat your oven’s broiler on high. Place the oven rack about 4 to 6 inches from the heating element.
If your oven has a broiler pan, use it. The slotted design allows fat to drip away, preventing smoke. If not, a baking sheet lined with foil works fine.
Step 4: Sear The Meat First
For extra flavor, sear the London broil on the stovetop before broiling. Heat a cast-iron skillet over high heat. Add a tablespoon of oil. Remove the meat from the marinade and pat it dry with paper towels. Searing dry meat gives a better crust.
Sear each side for 2 to 3 minutes until deeply browned. This step is optional but highly recommended. It adds a layer of flavor that broiling alone cannot achieve.
Step 5: Broil The London Broil
Transfer the seared meat to the broiler pan or baking sheet. Place it under the preheated broiler. Cook for 5 to 7 minutes per side for medium-rare. Use a meat thermometer to check doneness.
- Rare: 125°F (51°C)
- Medium-rare: 135°F (57°C)
- Medium: 145°F (63°C)
Remember, the temperature will rise a few degrees while resting. So pull it out 5 degrees below your target. Do not overcook—London broil becomes tough quickly.
Step 6: Rest The Meat
Resting is critical. Place the cooked meat on a cutting board and tent it loosely with foil. Let it rest for 10 minutes. This allows the juices to redistribute throughout the meat. If you cut too soon, the juices will run out, leaving dry meat.
Step 7: Slice Against The Grain
After resting, slice the London broil thinly against the grain. The grain is the direction of the muscle fibers. Cutting against them shortens the fibers, making each bite tender. Slice at a slight angle for wider pieces.
Use a sharp knife. Thick slices will be chewy. Aim for slices about 1/4 inch thick. Serve immediately.
How To Cook London Broil Oven: Tips For Perfect Results
Here are some extra tips to ensure success every time you cook London broil in the oven.
Use A Meat Thermometer
Do not guess the doneness. A meat thermometer is your best friend. Insert it into the thickest part of the meat. Digital instant-read thermometers give the most accurate reading.
Do Not Skip The Marinade
Even a short marinade helps. The acid in vinegar or citrus breaks down tough fibers. If you are short on time, marinate for at least 30 minutes. But longer is better.
Pat The Meat Dry Before Searing
Moisture is the enemy of a good sear. Pat the meat dry with paper towels before putting it in the hot pan. This ensures a deep brown crust.
Adjust Broiler Time Based On Thickness
A 1.5-inch thick cut needs about 5 to 6 minutes per side. A 2-inch cut needs 7 to 8 minutes per side. Always check with a thermometer.
Common Mistakes To Avoid
Even experienced cooks make mistakes with London broil. Here are the most common ones and how to avoid them.
Overcooking The Meat
London broil is lean and becomes tough when cooked beyond medium. Stick to medium-rare or medium at most. Use a thermometer to avoid guesswork.
Skipping The Resting Time
Cutting into the meat right away releases all the juices. You end up with dry meat. Always rest for at least 10 minutes.
Cutting With The Grain
This is the biggest mistake. Cutting with the grain leaves long fibers that are hard to chew. Always slice against the grain.
Not Preheating The Broiler
A cold broiler will not sear the meat properly. It will just cook it slowly, leading to a gray, tough exterior. Preheat for at least 10 minutes.
What To Serve With London Broil
London broil pairs well with many sides. Here are some ideas.
- Roasted potatoes or mashed potatoes
- Steamed green beans or asparagus
- A simple green salad with vinaigrette
- Sauteed mushrooms and onions
- Garlic bread or crusty rolls
The meat is flavorful on its own, but you can also serve it with a sauce. A red wine reduction or chimichurri works well.
How To Store And Reheat Leftovers
If you have leftovers, store them properly. Wrap the sliced meat tightly in foil or place it in an airtight container. Refrigerate for up to 3 days.
To reheat, use a low oven or a skillet. Avoid the microwave, which can make the meat rubbery. Place slices in a skillet with a splash of broth or water. Cover and heat on low for a few minutes.
