A well-marinated London broil needs high oven heat to develop a crust while keeping the interior medium-rare. If you are looking for a foolproof method on how to cook london broil in the oven, you have come to the right place. This guide will walk you through every step, from selecting the right cut to slicing it perfectly.
London broil is not actually a specific cut of meat. It is a cooking method, usually using top round or flank steak. The key is to cook it quickly at high heat and then slice it thinly against the grain. This ensures tenderness and flavor in every bite.
Many people think this dish is difficult, but it is actually quite simple. With the right technique, you can get a beautiful crust and a juicy center. Let us get started on making a perfect oven-baked London broil tonight.
What Is London Broil Exactly?
Before we dive into the oven method, let us clear up a common confusion. London broil is a dish, not a specific cut of beef. It typically refers to a lean cut like top round or flank steak that is marinated, broiled, and sliced thin.
The name is misleading because it did not originate in London. It became popular in the United States as a budget-friendly way to enjoy beef. The high heat of the oven or broiler helps tenderize the meat quickly.
When you buy a package labeled “London broil” at the store, you are usually getting a top round steak. This cut is very lean and benefits greatly from marinating. Do not skip the marinade step if you want a flavorful result.
How To Cook London Broil In The Oven
This is the section you have been waiting for. Follow these steps carefully to achieve a perfect result every time. The oven method gives you even heat and a nice crust without needing a grill.
Step 1: Choose The Right Cut And Prepare It
Start with a good piece of meat. Look for a London broil that is about 1 to 1.5 inches thick. Thicker cuts are easier to cook without drying out. The meat should be a deep red color with some marbling.
Before marinating, score the surface of the meat lightly with a sharp knife. Make shallow cuts in a diamond pattern on both sides. This helps the marinade penetrate deeper and also prevents the meat from curling during cooking.
Pat the meat dry with paper towels. This step is important for getting a good sear later. Wet meat will steam instead of browning properly.
Step 2: Make A Simple Marinade
A good marinade adds flavor and helps tenderize the lean meat. You need an acid, oil, and seasonings. Here is a basic recipe that works great:
- 1/2 cup soy sauce
- 1/4 cup olive oil
- 2 tablespoons red wine vinegar
- 3 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon black pepper
- 1 teaspoon dried rosemary
Mix all ingredients in a bowl or a zip-top bag. Add the London broil and turn to coat evenly. Seal the bag and refrigerate for at least 4 hours, but overnight is best. The longer it marinates, the more flavor you get.
Do not add salt to the marinade. Salt can draw moisture out of the meat, making it tough. Add salt just before cooking or after slicing.
Step 3: Preheat The Oven And Prepare The Pan
About 30 minutes before you want to cook, take the meat out of the fridge. Let it sit at room temperature. This helps it cook more evenly. While it rests, preheat your oven to 450°F (232°C).
Place a cast-iron skillet or heavy baking sheet inside the oven while it preheats. You want the pan to be very hot when you put the meat on it. This gives you an instant sear.
If you do not have cast iron, use a heavy-duty baking sheet. Just make sure it can handle high heat without warping. Line it with foil for easier cleanup, but do not skip preheating the pan.
Step 4: Sear The Meat On The Stovetop (Optional But Recommended)
For the best crust, sear the London broil on the stovetop first. Heat a tablespoon of oil in a heavy skillet over high heat until it shimmers. Remove the meat from the marinade and let excess drip off.
Place the meat in the hot skillet. Cook for 2-3 minutes per side until a deep brown crust forms. Do not move the meat while it sears; let it develop color. This step adds tremendous flavor.
If you are short on time, you can skip the stovetop sear. The high oven heat will still give you a decent crust. But the stovetop method is superior for flavor and texture.
Step 5: Roast In The Oven To Desired Doneness
Transfer the seared meat to the preheated pan in the oven. If you did not sear, place the marinated meat directly on the hot pan. Roast at 450°F for about 8-12 minutes, depending on thickness.
For a 1-inch thick London broil, aim for 8-10 minutes for medium-rare. Use an instant-read thermometer to check doneness. The internal temperature should be 130-135°F for medium-rare.
Here are target temperatures for different doneness levels:
- Rare: 125°F (about 6-8 minutes)
- Medium-rare: 130-135°F (8-10 minutes)
- Medium: 140-145°F (10-12 minutes)
- Medium-well: 150°F (12-14 minutes)
Remember that the meat will continue to cook after you take it out. Remove it from the oven about 5°F below your target temperature. This is called carryover cooking.
Step 6: Rest The Meat Before Slicing
This step is critical. Do not skip it. Transfer the cooked London broil to a cutting board and tent it loosely with foil. Let it rest for 10-15 minutes.
Resting allows the juices to redistribute throughout the meat. If you cut it too soon, all the juices will run out onto the board. You will end up with dry, tough meat.
While the meat rests, you can prepare a quick pan sauce or side dishes. The resting time is also a good moment to check your side dishes and make sure everything is ready.
Step 7: Slice Thinly Against The Grain
This is the most important step for tenderness. London broil is a lean cut, and slicing it correctly makes all the difference. You must slice against the grain.
The grain is the direction the muscle fibers run. Look at the surface of the meat and find the lines. Slice perpendicular to those lines, not parallel to them. This shortens the fibers and makes the meat easier to chew.
Use a sharp knife and cut thin slices, about 1/4 inch thick. Thicker slices will be tougher. Angle your knife slightly for wider, more elegant slices if you prefer.
Tips For The Best Oven London Broil
Here are some extra tips to help you succeed. These small details can make a big difference in the final result. Pay attention to them for a restaurant-quality meal.
Use A Meat Thermometer
Do not guess the doneness. A meat thermometer is your best friend for this dish. It takes the guesswork out and ensures perfect results every time.
Insert the thermometer into the thickest part of the meat. Make sure it is not touching bone or fat. Read the temperature after a few seconds for an accurate measurement.
Do Not Overcook
London broil is very lean and becomes tough when overcooked. Medium-rare is the ideal doneness for this cut. If you cook it past medium, it will be dry and chewy.
If you prefer well-done meat, consider a different cut like chuck or brisket. Those cuts have more fat and connective tissue that break down with longer cooking. London broil is best enjoyed rare to medium.
Let The Marinade Work
Do not rush the marinating process. At least 4 hours is needed for the flavors to penetrate. Overnight marinating gives the best results. The acid in the marinade helps break down tough muscle fibers.
If you are in a hurry, you can use a Jaccard meat tenderizer. This tool pokes small holes in the meat, allowing the marinade to penetrate faster. But nothing beats time for flavor development.
What To Serve With London Broil
London broil pairs well with many side dishes. Since it is a lean protein, you can serve it with hearty sides. Here are some classic options:
- Roasted potatoes or mashed potatoes
- Steamed green beans or asparagus
- A simple green salad with vinaigrette
- Sauteed mushrooms and onions
- Rice pilaf or quinoa
The pan juices from the oven can be used to make a quick sauce. Deglaze the pan with a splash of beef broth or red wine. Scrape up the browned bits and simmer for a minute. Pour this over the sliced meat.
Common Mistakes To Avoid
Even experienced cooks can make mistakes with London broil. Here are some common pitfalls and how to avoid them. Learn from these to improve your results.
Skipping The Resting Step
This is the most common mistake. People are eager to eat and cut into the meat immediately. This causes all the juices to spill out, leaving dry meat.
Always rest the meat for at least 10 minutes. Use this time to finish your side dishes or set the table. Your patience will be rewarded with juicy, tender slices.
Slicing With The Grain
Another frequent error is slicing in the wrong direction. If you slice with the grain, each bite will be long and stringy. The meat will be difficult to chew.
Take a moment to identify the grain before slicing. Cut perpendicular to the lines. If you are unsure, make a small cut and check the direction of the fibers.
Using Too Low Heat
Some people try to cook London broil at a lower temperature, thinking it will be more tender. This is incorrect. Low heat will dry out the meat before it develops a crust.
High heat is essential for a good sear and a juicy interior. The oven must be at least 450°F. Do not be afraid of the high temperature; it is the correct method.
Frequently Asked Questions
Can I Cook London Broil Without A Marinade?
Yes, you can, but the meat will be less flavorful and tougher. The marinade adds moisture and helps break down fibers. If you skip it, consider using a dry rub and letting it sit for an hour before cooking.
How Do I Reheat Leftover London Broil Without Drying It Out?
Reheat slices gently in a skillet with a little beef broth or butter. Cover the pan to trap steam. You can also reheat in the oven at 300°F, wrapped in foil with a splash of broth. Avoid the microwave, which will make it tough.
Is London Broil The Same As Flank Steak?
Not exactly. London broil is often made from top round, while flank steak is a different cut. Both are lean and benefit from similar cooking methods. However, flank steak is more tender and has a looser grain.
What If My London Broil Is Too Thick?
If your cut is thicker than 1.5 inches, you may need to adjust cooking time. Use a meat thermometer to check doneness. You can also butterfly the meat to make it thinner, but this changes the presentation.
Can I Use This Method For Other Cuts Of Beef?
Yes, this high-heat oven method works well for other lean cuts like sirloin or flank steak. Adjust cooking time based on thickness. Always let the meat rest and slice against the grain for best results.
