London broil: the name conjures images of sizzling steaks and hearty family dinners. But it also carries a reputation, one that whispers of potential toughness. Is this reputation deserved? Does London broil inevitably lead to a jaw-aching workout, or can it be transformed into a tender, flavorful delight? Let’s delve deep into the world of London broil, exploring its origins, characteristics, proper preparation, and debunking the myth of its inherent toughness.
Understanding London Broil: What It Is and Where It Comes From
London broil isn’t a specific cut of beef, like a ribeye or filet mignon. Instead, it’s a preparation method often applied to a relatively lean and economical cut of beef, most commonly the flank steak. Sometimes, the top round steak is also used, albeit less frequently.
The term “London broil” is a bit of a misnomer. Its origins aren’t definitively traced back to London, England. Food historians believe it emerged in North America, likely in the early to mid-20th century. The name might have been chosen to evoke a sense of sophistication and culinary flair.
The key element that defines London broil is the marinating process followed by high-heat broiling or grilling. The combination of these two techniques aims to tenderize the meat and infuse it with flavor.
Flank Steak vs. Top Round: The Contenders
Flank steak is located in the abdominal area of the cow. It’s a relatively thin, flat cut with prominent muscle fibers running lengthwise. This grain structure is crucial to understand when preparing flank steak, as slicing against the grain is paramount for tenderness.
Top round, on the other hand, comes from the rear leg of the cow. It’s a larger, thicker cut that’s also lean. While it can be used for London broil, it’s generally considered less desirable than flank steak due to its inherent toughness and drier texture.
Choosing between flank steak and top round for London broil depends on personal preference and budget. Flank steak is generally more expensive but offers a superior flavor and tenderness profile. Top round is a more budget-friendly option but requires extra attention to marinating and cooking to achieve acceptable results.
The Toughness Factor: Why the Reputation?
The perception of London broil as a tough cut stems from several factors, primarily related to improper preparation and cooking techniques.
Firstly, overcooking is a major culprit. Both flank steak and top round are lean cuts, meaning they lack significant marbling (intramuscular fat). When cooked beyond medium-rare, these cuts tend to dry out and become tough. The muscle fibers tighten, squeezing out any remaining moisture.
Secondly, insufficient marinating can contribute to toughness. Marinades typically contain acidic ingredients (like vinegar or citrus juice) that help break down muscle fibers. They also often include oil, which helps to moisturize the meat, and flavorful components like herbs, spices, and garlic. A short or ineffective marinade won’t adequately tenderize the meat.
Thirdly, incorrect slicing is a common mistake. As mentioned earlier, flank steak has a distinct grain structure. Slicing with the grain results in long, unbroken muscle fibers that are difficult to chew. Slicing against the grain shortens these fibers, making the meat significantly more tender.
Finally, using the wrong cut can also lead to disappointment. If top round is used and not properly tenderized, the result can be a tough and unappetizing London broil. Even flank steak, if of poor quality or improperly handled, can be tough.
Tenderizing Techniques: The Key to Success
Overcoming the potential toughness of London broil requires employing effective tenderizing techniques. These techniques focus on breaking down muscle fibers and adding moisture.
Marinating is the most crucial step. A good marinade should contain an acidic component (vinegar, citrus juice, wine), oil, and flavoring agents. The acidic component helps to denature proteins and break down muscle fibers. Oil helps to prevent moisture loss during cooking. Flavoring agents infuse the meat with delicious aromas and tastes. Marinade times can vary, but generally, a minimum of 2 hours and up to 24 hours is recommended for flank steak. For top round, a longer marinating time (12-24 hours) is often necessary.
Mechanical tenderization can also be used, although it’s less common. This involves using a meat mallet or a Jaccard meat tenderizer to physically break down the muscle fibers. Be cautious not to overdo it, as excessive pounding can result in a mushy texture.
Salting in advance is another effective technique. Applying salt to the meat 1-2 hours before cooking allows the salt to penetrate the muscle fibers and denature proteins. This results in a more tender and flavorful final product.
Proper cooking temperature is paramount. London broil is best cooked to medium-rare or medium. Using a meat thermometer is essential to ensure accurate doneness. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C). For medium, aim for 135-145°F (57-63°C).
Resting the meat after cooking is crucial. Allowing the meat to rest for 10-15 minutes allows the juices to redistribute throughout the muscle fibers, resulting in a more moist and tender final product. Tenting the meat loosely with foil helps to retain heat.
Cooking Methods: Broiling vs. Grilling
London broil can be cooked using either broiling or grilling, both methods employing high heat to achieve a flavorful sear.
Broiling involves cooking the meat under direct heat from an overhead broiler. This method is quick and convenient, making it ideal for weeknight dinners. To broil London broil, preheat the broiler and position the rack so that the meat is about 4-6 inches from the heat source. Broil for 4-6 minutes per side for medium-rare, or slightly longer for medium.
Grilling offers a smoky flavor that many people enjoy. Preheat the grill to high heat. Grill the London broil for 3-5 minutes per side for medium-rare, or slightly longer for medium.
Regardless of the cooking method, it’s essential to avoid overcooking. Use a meat thermometer to ensure accurate doneness and prevent the meat from drying out.
Slicing Against the Grain: The Final Touches
As previously emphasized, slicing against the grain is essential for achieving a tender London broil. After resting the meat, identify the direction of the muscle fibers. Use a sharp knife to slice the meat thinly, perpendicular to the grain. This shortens the muscle fibers, making them easier to chew.
Serve the sliced London broil immediately. It can be enjoyed on its own, as part of a salad, or in sandwiches.

Debunking the Myth: London Broil Can Be Tender
The notion that London broil is inherently tough is simply a myth. When prepared correctly, using the right cut of meat, a flavorful marinade, proper cooking techniques, and careful slicing, London broil can be incredibly tender and delicious.
The key is to understand the characteristics of the meat, employ effective tenderizing methods, and avoid overcooking. With a little knowledge and attention to detail, you can transform London broil from a potentially tough cut into a flavorful and satisfying meal. So, don’t let the reputation scare you away. Embrace the potential of London broil and discover the joy of a perfectly cooked, tender steak.
Is London Broil inherently a tough cut of meat?
London broil, often cut from the flank steak or top round, is generally considered a leaner and therefore potentially tougher cut of meat compared to more marbled options like ribeye. The lack of significant intramuscular fat means it can easily become dry and chewy if not cooked properly. It’s important to remember, however, that proper preparation and cooking techniques play a crucial role in determining the final texture.
The inherent toughness of London broil can be mitigated. Techniques like marinating to tenderize the meat fibers and cooking to the correct internal temperature (medium-rare to medium is ideal) are key to preventing it from becoming overly tough. Slicing thinly against the grain after cooking is also essential for a tender and enjoyable eating experience.
What’s the key to making London Broil tender?
The secret to a tender London broil lies primarily in two crucial steps: marinating and proper cooking. Marinating helps to break down the muscle fibers, tenderizing the meat before it even hits the heat. A good marinade typically includes an acidic component (like vinegar or citrus juice), oil, and seasonings to both tenderize and impart flavor.
Cooking the London broil to the correct internal temperature is just as important. Overcooking will cause the muscle fibers to tighten and expel moisture, resulting in a tough and dry piece of meat. Aim for a medium-rare (130-135°F) to medium (135-140°F) doneness for the most tender results. Remember to use a meat thermometer to ensure accuracy.
How does marinating impact the tenderness of London Broil?
Marinating significantly impacts the tenderness of London broil by penetrating the meat and breaking down the muscle fibers. The acidic components in the marinade, such as vinegar or lemon juice, denature proteins, weakening their structure. This process allows the meat to become more pliable and less resistant to chewing.
Beyond tenderizing, a good marinade also infuses the London broil with flavor. The longer the meat marinates (within safe limits), the deeper the flavor penetration. Typically, a minimum of 30 minutes is recommended, but several hours or even overnight marinating can yield even more tender and flavorful results, provided the marinade isn’t overly acidic.
What are the best cooking methods for London Broil to prevent toughness?
High-heat cooking methods like grilling or broiling are often favored for London broil, but precise timing is critical to prevent toughness. The high heat sears the outside, creating a flavorful crust, while ideally leaving the inside medium-rare to medium. Overcooking is the biggest risk with these methods.
Another method to consider is reverse searing. This involves cooking the London broil at a lower temperature in the oven until it’s close to the desired internal temperature, then searing it in a hot pan or on a grill to develop the crust. This allows for more even cooking and a more tender result. Slow cooking or braising are generally not recommended as they can result in a less desirable texture for this cut.
Why is slicing London Broil against the grain so important?
Slicing London broil against the grain is crucial for maximizing tenderness because it shortens the muscle fibers. Muscle fibers run lengthwise through the meat, and if you slice with the grain, you’re essentially chewing through long, tough strands.
By slicing against the grain, you’re cutting those long fibers into shorter segments, making them much easier to chew. Identifying the grain direction is essential; look closely at the meat before slicing and cut perpendicular to the direction of the fibers. This single step can significantly improve the perceived tenderness of the London broil.
Can I use a meat tenderizer on London Broil?
Yes, a meat tenderizer can be used on London broil to further enhance its tenderness. Both mechanical tenderizers (like a meat mallet) and enzymatic tenderizers (containing ingredients like bromelain or papain) can be effective. However, use them with caution.
Over-tenderizing can result in a mushy or unappealing texture. Mechanical tenderizers should be used gently to avoid completely breaking down the meat fibers. Enzymatic tenderizers should be used sparingly, following the product instructions carefully to avoid over-tenderizing and potentially altering the flavor profile too much. Marinating often provides sufficient tenderization without the risks of overdoing it with tenderizers.
What internal temperature should I aim for when cooking London Broil?
The ideal internal temperature for London broil depends on your preferred level of doneness. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C). For medium, the target temperature is 135-140°F (57-60°C).
It’s crucial to use a reliable meat thermometer to accurately measure the internal temperature. Insert the thermometer into the thickest part of the meat, avoiding bone. Remember that the meat will continue to cook slightly (carryover cooking) after being removed from the heat, so it’s best to pull it off the heat when it’s a few degrees below your target temperature.
