London broil. The name itself evokes images of hearty family dinners and sizzling grills. But it also carries a reputation – a reputation for being tough. Is this reputation deserved? Or is London broil simply a misunderstood cut of meat, victimized by improper preparation? Let’s delve into the truth and explore how to transform this affordable cut into a tender and flavorful masterpiece.
Understanding London Broil: What Exactly Is It?
First and foremost, let’s clarify what we’re actually talking about. The term “London broil” can be confusing because it doesn’t refer to a specific cut of beef. Instead, it’s a cooking method and a cut. Traditionally, it refers to flank steak, but sometimes top round steak is also sold under this name. Understanding this distinction is the first step in demystifying its potential toughness.
Flank Steak vs. Top Round: The Key Difference
Flank steak comes from the abdominal muscles of the cow. It’s a relatively thin, wide cut with prominent muscle fibers running lengthwise. It has a rich, beefy flavor but can become tough if overcooked due to these fibers. Top round, on the other hand, comes from the rear leg. It’s a leaner, thicker cut, also with visible grain, although often less pronounced than in flank steak. It’s typically less expensive than flank steak, but it also has the potential to be tougher if not prepared correctly.
Knowing which cut you’re dealing with is crucial. Flank steak typically benefits more from marinating and high-heat, quick cooking, while top round can benefit from longer, slower cooking methods or tenderizing.
Why the Toughness Perception? Unmasking the Culprits
Several factors contribute to London broil’s reputation for toughness. The primary reasons usually boil down to incorrect cooking techniques, lack of proper preparation, and occasionally, the quality of the meat itself.
Overcooking: The Number One Offender
The most common mistake is overcooking. Both flank steak and top round contain muscle fibers that contract and tighten when exposed to high heat for too long. This squeezing action forces out moisture, resulting in a dry and chewy piece of meat. London broil is best served medium-rare to medium, allowing the fibers to remain relaxed and juicy.
Cutting Against the Grain: A Critical Step Often Missed
Another vital factor is slicing the cooked meat against the grain. As mentioned, both flank and top round have noticeable muscle fibers. If you slice with the grain, you’re essentially cutting along these long, tough fibers, making the meat harder to chew. Cutting against the grain shortens these fibers, making each bite significantly more tender.
Lack of Marination: A Missed Opportunity for Flavor and Tenderness
Marinating London broil is highly recommended, especially for flank steak. Marinades serve two important purposes: they infuse the meat with flavor, and they can help tenderize it. Marinades containing acidic ingredients like vinegar, lemon juice, or wine can help break down the muscle fibers, resulting in a more tender final product.
Inferior Meat Quality: Starting with a Disadvantage
While proper preparation can significantly improve the tenderness of London broil, the initial quality of the meat also plays a role. Meat from older animals or animals raised in less-than-ideal conditions may naturally be tougher. Look for cuts that are well-marbled (have flecks of fat throughout the muscle) and have a vibrant red color. Choosing a higher grade of beef, such as Choice or Prime, can also make a difference.
Transforming London Broil: Techniques for Tenderness and Flavor
Now that we’ve identified the culprits behind tough London broil, let’s explore the solutions. With the right techniques, you can transform this affordable cut into a delicious and tender meal.
Marinating Magic: Infusing Flavor and Tenderizing
Marinating is your secret weapon. A good marinade should contain three key components: acid, oil, and aromatics. The acid (vinegar, lemon juice, wine) helps tenderize the meat. The oil helps carry the flavor and prevents the meat from drying out. And the aromatics (garlic, herbs, spices) add depth and complexity.
A simple marinade could include:
- 1/4 cup olive oil
- 1/4 cup red wine vinegar
- 2 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried oregano
- Salt and pepper to taste
Marinate the London broil for at least 30 minutes, but preferably for several hours or even overnight in the refrigerator. The longer it marinates, the more tender and flavorful it will become.
Cooking Methods: Mastering the Heat
The best cooking method for London broil depends on the cut. Flank steak is best suited for high-heat cooking methods like grilling or broiling. Top round can benefit from slower cooking methods like braising or roasting at a lower temperature.
Grilling: Quick and Smoky Perfection
For flank steak, grilling is an excellent choice. Preheat your grill to high heat. Remove the steak from the marinade and pat it dry with paper towels. Grill for 4-5 minutes per side for medium-rare, or longer if you prefer it more well-done. Use a meat thermometer to ensure you don’t overcook it. Aim for an internal temperature of 130-135°F for medium-rare, 135-140°F for medium.
Broiling: Indoor Grilling Alternative
If you don’t have a grill, broiling is a good alternative. Preheat your broiler to high. Place the steak on a broiler pan and broil for 4-5 minutes per side for medium-rare, flipping once. Watch it carefully to prevent burning.
Roasting: A Gentle Approach for Top Round
For top round, roasting at a lower temperature can yield more tender results. Preheat your oven to 325°F. Season the steak with salt, pepper, and your favorite herbs. Place it on a roasting rack and roast for 20-30 minutes, or until it reaches an internal temperature of 130-135°F for medium-rare, 135-140°F for medium.
Braising: Low and Slow for Maximum Tenderness
Braising is another excellent option for top round, particularly if you want a very tender result. Sear the steak in a hot pan with oil until browned on all sides. Then, add braising liquid (beef broth, wine, or a combination), vegetables, and herbs to the pan. Cover and simmer in the oven or on the stovetop for 2-3 hours, or until the steak is fork-tender.
Resting: An Essential Step for Juicy Results
After cooking, it’s crucial to let the London broil rest for at least 10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. Tent the steak loosely with foil while it rests to keep it warm.
Slicing Against the Grain: The Final Touches
As mentioned earlier, slicing against the grain is essential for tenderness. Identify the direction of the muscle fibers and slice perpendicular to them. This will shorten the fibers, making each bite easier to chew.
Beyond the Basics: Exploring Flavor Variations
Once you’ve mastered the basics of cooking London broil, you can start experimenting with different marinades and flavor combinations.
-
Asian-Inspired: Combine soy sauce, ginger, garlic, sesame oil, and a touch of honey for a flavorful Asian-inspired marinade.
-
Mediterranean: Use olive oil, lemon juice, oregano, thyme, and garlic for a Mediterranean twist.
-
Spicy Southwestern: Add chili powder, cumin, paprika, and a pinch of cayenne pepper to your marinade for a spicy Southwestern flavor.
Addressing Common Concerns About London Broil
Many home cooks have specific concerns and questions about preparing London broil. Let’s address some of the most common ones.
What if I accidentally overcook my London broil?
If you accidentally overcook your London broil, don’t despair. While it won’t be as tender as it could have been, you can still salvage it. Slice it very thinly against the grain and serve it in a sauce or gravy. This will help add moisture and flavor. You can also use it in sandwiches or salads.
Can I use a meat tenderizer on London broil?
Yes, you can use a meat tenderizer on London broil, especially on top round. A meat tenderizer contains enzymes that help break down the muscle fibers, making the meat more tender. Follow the instructions on the package for best results.
How do I know when my London broil is done?
The best way to determine when your London broil is done is to use a meat thermometer. Insert the thermometer into the thickest part of the steak, avoiding bone. Aim for an internal temperature of 130-135°F for medium-rare, 135-140°F for medium.

Embrace the techniques outlined and rediscover London Broil as a delicious and economical option for your next meal.
Is London Broil inherently a tough cut of meat?
London broil is often perceived as tough, and this reputation stems largely from how it’s cooked and served rather than the inherent quality of the cut itself. It typically comes from the flank steak, a lean and relatively tough muscle located in the abdominal area of the cow. Because of its leanness and the muscle fibers running in one direction, improper cooking can easily lead to a chewy and unpleasant texture.
However, when cooked correctly, London broil can be surprisingly tender and flavorful. Key techniques like marinating, searing at high heat, and slicing against the grain are crucial in breaking down the muscle fibers and enhancing its tenderness. So, while it has the potential to be tough, proper preparation techniques can prevent this and transform it into a delicious meal.
What makes London Broil potentially tougher than other cuts of beef?
The inherent toughness of London broil primarily lies in its muscle fiber structure and low fat content. The long, dense muscle fibers running along the length of the flank steak require intervention to become tender. Unlike more marbled cuts with intramuscular fat that melts during cooking and naturally tenderizes the meat, London broil lacks this natural tenderization mechanism.
Therefore, without marinating or careful cooking, these muscle fibers can contract and become even tougher during the cooking process. This is why techniques like marinating with acidic ingredients and proper slicing against the grain are so vital to breaking down the muscle fibers and improving the overall texture and eating experience.
How does marinating affect the tenderness of London Broil?
Marinating London broil is essential for tenderizing the meat and enhancing its flavor profile. Marinades typically contain acidic ingredients like vinegar, citrus juice, or wine, which help to break down the muscle fibers and collagen proteins responsible for the toughness. This process allows the meat to absorb moisture, resulting in a more tender and juicy final product.
Additionally, marinades often include oil and herbs, which further contribute to the flavor and help to retain moisture during cooking. A good marinade penetrates the surface of the meat, improving both the texture and the overall taste experience. The duration of marinating is also important, usually ranging from a few hours to overnight, depending on the acidity and potency of the marinade.
What is the best way to cook London Broil to avoid toughness?
The best cooking method for London Broil involves high heat and precise temperature control. Searing the meat at a high temperature, either on a grill or in a cast-iron skillet, creates a flavorful crust and helps to seal in the juices. This quick searing process prevents excessive moisture loss, contributing to a more tender result.
The ideal internal temperature for London broil is medium-rare to medium (130-145°F). Overcooking will undoubtedly lead to a tough and dry texture. Using a meat thermometer to monitor the internal temperature is highly recommended. After cooking, allowing the meat to rest for 5-10 minutes before slicing is crucial, as it allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful bite.
Why is slicing London Broil against the grain so important?
Slicing London broil against the grain is arguably the most crucial step in preventing toughness. The long muscle fibers run in a single direction across the width of the flank steak. Slicing against the grain essentially shortens these fibers, making them easier to chew and significantly reducing the perceived toughness.
Imagine trying to chew long, unbroken strands of fiber versus short, manageable pieces. By cutting across the grain, you are essentially doing the “pre-chewing” for yourself. This step dramatically improves the texture and makes even a potentially tough cut like London broil remarkably tender and enjoyable. Always identify the direction of the grain before slicing and cut perpendicular to it.
What are some common mistakes people make when cooking London Broil?
One of the most frequent mistakes when cooking London Broil is overcooking it. Because the cut is lean, it dries out quickly when cooked beyond medium, resulting in a tough and chewy texture. Neglecting to use a meat thermometer and relying solely on visual cues is a common cause of overcooking.
Another frequent mistake is skipping the marinating step. While not strictly mandatory, marinating significantly enhances the tenderness and flavor of London broil. Failing to marinate, especially with an acidic marinade, deprives the meat of a crucial tenderizing process. Finally, not slicing against the grain completely negates all other efforts to tenderize the meat, as the long muscle fibers remain intact and difficult to chew.
What are some alternative cuts of beef that are similar to London Broil?
If you’re looking for alternatives to London broil, consider cuts like flank steak, skirt steak, or flat iron steak. Flank steak is, in fact, the most common cut used for London broil, making it a direct substitute. Skirt steak, known for its intense flavor, is another great option, especially for grilling.
Flat iron steak, cut from the shoulder of the cow, is naturally more tender than flank steak and is also a suitable alternative. All these cuts benefit from similar cooking techniques, including marinating, searing, and slicing against the grain. The choice ultimately depends on your personal preference for flavor and texture, but they all offer a similar culinary experience.
