The world of beef cuts can be confusing, especially when names are used interchangeably or regional variations come into play. Two cuts often mentioned in the same breath are top round London broil and flank steak. While both are relatively lean and flavorful, understanding their differences is crucial for achieving optimal cooking results. This article will delve into the nuances of each cut, exploring their origins, characteristics, best cooking methods, and how to tell them apart.
Understanding the Origins of Top Round and Flank Steak
To truly grasp the distinctions, it’s important to understand where these cuts come from on the cow. This helps in appreciating their textural and flavor profiles.
The Anatomy of the Top Round
The top round, as the name suggests, is located on the inner thigh of the cow, specifically in the round primal cut. This area gets a decent amount of exercise, leading to a leaner cut with less marbling than some other steaks. The round primal is often divided into several sub-primal cuts, including the top round, bottom round, and eye of round. The top round is generally considered the most tender of these.
The Anatomy of Flank Steak
Flank steak, on the other hand, comes from the abdominal muscles of the cow, specifically from the flank primal. This area also sees considerable activity, resulting in a relatively tough cut with a good amount of muscle fibers. Flank steak is known for its distinctive grain, which runs lengthwise along the cut.
Key Characteristics: Top Round vs. Flank Steak
Beyond their location on the animal, top round and flank steak possess distinct qualities that affect their taste and how they should be prepared.
Top Round: Lean and Mild
Top round is known for its lean texture and relatively mild flavor. It lacks the intense beefy taste found in some other cuts. Because of its leanness, it can easily become dry and tough if overcooked. However, when cooked properly, it can be a delicious and economical option. It often benefits from marinating to tenderize the meat and add flavor.
Flank Steak: Flavorful and Grainy
Flank steak boasts a robust, beefy flavor that many find incredibly appealing. Its pronounced grain is a defining characteristic. This grain is essential to consider when slicing, as cutting against the grain is crucial for ensuring tenderness. Flank steak also benefits from marinating, which helps to break down the muscle fibers and enhance its flavor.
London Broil: A Method, Not Necessarily a Cut
The term “London broil” adds another layer of complexity to the discussion. It’s important to clarify that London broil is primarily a cooking method, not a specific cut of beef. While it is frequently associated with flank steak, top round is also often used as a London broil. The method typically involves marinating a relatively thick cut of beef and then broiling or grilling it at high heat. After cooking, the meat is sliced thinly against the grain.
Cooking Methods: How to Maximize Flavor and Tenderness
Both top round and flank steak benefit from specific cooking approaches to achieve the best results.
Cooking Top Round for London Broil
When using top round for London broil, marinating is essential. A marinade will help tenderize the meat and infuse it with flavor. Broiling or grilling at high heat is common, but it’s crucial to avoid overcooking. Aim for medium-rare to medium doneness, as top round can become tough if cooked beyond this point. Slicing thinly against the grain after cooking is crucial for maximizing tenderness. A meat thermometer is very helpful to monitor internal temperature.
Cooking Flank Steak for London Broil
Flank steak is naturally more flavorful than top round and often requires less marinating time. However, marinating is still recommended to further tenderize the meat and enhance its flavor. Grilling or pan-searing at high heat are popular methods for cooking flank steak. Again, avoid overcooking. Medium-rare to medium is ideal. Similar to top round, slicing thinly against the grain is paramount for achieving a tender and enjoyable eating experience. A quick sear on a hot cast-iron pan yields a beautiful crust.
Visual Differences: Identifying Top Round and Flank Steak
Being able to visually distinguish between top round and flank steak can be incredibly helpful when shopping.
Identifying Top Round
Top round typically appears as a thick, rectangular cut with a relatively uniform shape. It has very little marbling, giving it a lean appearance. The grain is less pronounced compared to flank steak. Look for a bright red color, indicating freshness.
Identifying Flank Steak
Flank steak is generally thinner and wider than top round. Its most distinguishing feature is its prominent grain, which runs lengthwise along the cut. It may also have a slightly coarser texture compared to top round. Look for a vibrant red color and avoid cuts that appear brown or dull.
Flavor Profiles: A Matter of Taste
While both cuts can be delicious, their inherent flavors differ.
The Flavor of Top Round
Top round has a milder, more subtle flavor than flank steak. It’s not as intensely beefy and can sometimes be perceived as bland if not properly seasoned or marinated. Its mild flavor also makes it a versatile ingredient that pairs well with a variety of sauces and seasonings.
The Flavor of Flank Steak
Flank steak boasts a rich, beefy flavor that is often described as robust and satisfying. Its pronounced flavor comes from the muscle fibers and slight amount of fat within the cut. This intense flavor makes it a popular choice for grilling, stir-fries, and other dishes where the beef flavor is meant to be the star.
Price and Availability
Price and availability can vary depending on location and time of year.
Cost Considerations for Top Round

Cost Considerations for Flank Steak
Flank steak typically commands a higher price than top round due to its more desirable flavor and texture. While still relatively affordable compared to prime cuts, it’s considered a mid-range option. Its robust flavor and versatility make it a worthwhile investment for many cooks.
Substituting Top Round and Flank Steak: Is it Possible?
While not ideal, substituting one cut for the other is possible in some situations, with adjustments to the cooking method.
Substituting Top Round for Flank Steak
If substituting top round for flank steak, marinating is even more critical. Choose a flavorful marinade to compensate for the top round’s milder taste. Pay close attention to cooking time to avoid overcooking, as top round can become tough more easily than flank steak. Slicing thinly against the grain is essential.
Substituting Flank Steak for Top Round
If substituting flank steak for top round, you may need to reduce the marinating time slightly, as flank steak can absorb flavors more quickly. Be mindful of the cooking time and don’t overcook the flank steak, especially if you’re used to the slightly longer cooking time often associated with top round.
London Broil Recipe Adaptations: Tailoring to Your Cut
Regardless of which cut you choose for London broil, understanding how to adapt your recipe is key.
Adapting Recipes for Top Round
When using top round for a London broil recipe, consider adding ingredients to your marinade that specifically aim to tenderize the meat, such as vinegar, lemon juice, or enzymes like bromelain (found in pineapple). Increase the marinating time to allow the flavors to penetrate deeply. Be extra cautious about cooking time and use a meat thermometer to ensure you don’t overcook it.
Adapting Recipes for Flank Steak
When using flank steak for a London broil recipe, you can often get away with a simpler marinade and a shorter marinating time. Focus on ingredients that complement the beefy flavor of the flank steak, such as garlic, herbs, and soy sauce. Keep a close eye on the cooking time and aim for medium-rare to medium doneness.
Beyond London Broil: Exploring Other Culinary Applications
Both top round and flank steak are versatile cuts that can be used in a variety of dishes beyond London broil.
Top Round Applications
Top round is commonly used for roast beef, stews, and sandwich meat. It can also be thinly sliced and used in stir-fries. Its leanness makes it a good option for those looking to reduce their fat intake.
Flank Steak Applications
Flank steak is a popular choice for fajitas, carne asada, and grilled steak salads. Its robust flavor and ability to stand up to high heat make it ideal for these dishes. It can also be used in stir-fries and other Asian-inspired dishes.
In conclusion, while the terms “top round London broil” and “flank steak” are often used interchangeably, they represent distinct cuts of beef with unique characteristics. Top round is leaner and milder in flavor, while flank steak is more flavorful and has a pronounced grain. London broil is a cooking method that can be applied to either cut. Understanding these differences will allow you to choose the right cut for your desired dish and cook it to perfection.
Is Top Round London Broil Actually Flank Steak?
No, top round and flank steak are not the same cut of meat. Top round comes from the rear leg of the cow, while flank steak is cut from the abdominal muscles. They are both relatively lean cuts, making them suitable for grilling or broiling, but their textures and best preparation methods differ considerably.
Flank steak is known for its pronounced grain and is best cooked hot and fast, then sliced thinly against the grain for maximum tenderness. Top round, on the other hand, can be a bit tougher and benefits from marinating or braising to tenderize it. While “London Broil” is often associated with flank steak, it’s frequently prepared with top round due to its lower cost and availability.
What are the Key Differences in Texture Between Top Round and Flank Steak?
The most noticeable difference is the muscle fiber structure. Flank steak has a very distinct, easily visible grain running lengthwise across the steak. This grain contributes to its chewiness if not sliced correctly. Top round, while still having a grain, is not as pronounced, and the meat generally has a denser, somewhat less fibrous texture.
Because of these textural differences, flank steak tends to absorb marinades more readily than top round, making it a preferred choice for quick marinades before grilling. Top round’s tighter grain means marinades might take longer to penetrate, and it can sometimes benefit from mechanical tenderization before cooking.
Why is Top Round Often Sold as “London Broil?”
“London Broil” isn’t actually a specific cut of meat; it’s a cooking method, namely broiling or grilling a large, relatively lean piece of beef, then slicing it thinly against the grain. However, over time, it became strongly associated with flank steak due to the cut’s suitability for this style of cooking. Unfortunately, flank steak is often more expensive and harder to find than top round.
Therefore, many grocery stores and butchers will label top round as “London Broil” to capitalize on the popularity of the dish and to offer a more affordable option. This can be misleading for consumers expecting the distinct texture and flavor profile of flank steak. It’s essential to examine the cut of meat carefully to determine what you’re actually buying.
What Cooking Methods Work Best for Top Round vs. Flank Steak?
Flank steak thrives with high-heat cooking methods like grilling or pan-searing. The goal is to achieve a good sear on the outside while keeping the inside medium-rare to medium. After cooking, it’s crucial to let it rest before slicing thinly against the grain at an angle.
Top round is more versatile but requires different techniques depending on your desired outcome. While it can be grilled or broiled, it benefits greatly from marinating or tenderizing beforehand. Braising or slow-cooking methods are also excellent choices for top round, as they help to break down the muscle fibers and create a more tender result.
How Does Marinating Affect Top Round and Flank Steak Differently?
Due to its looser muscle structure, flank steak readily absorbs marinades, typically within 30 minutes to a few hours. Marinades help tenderize the meat and infuse it with flavor, making it ideal for grilling. The porous nature of flank steak allows for quicker and more substantial absorption of flavors from the marinade.
Top round, with its denser texture, requires longer marinating times, ideally several hours or even overnight, to achieve significant tenderization and flavor infusion. Marinades containing acidic ingredients, such as vinegar or citrus juice, are particularly helpful for breaking down the muscle fibers in top round. Mechanical tenderization prior to marinating can also improve results.
Can I Substitute Top Round for Flank Steak in Recipes?
While you can substitute top round for flank steak, you’ll need to adjust your cooking method and expectations. Top round is generally tougher, so it needs to be tenderized or marinated longer. Consider pounding the top round to break down some of the muscle fibers before marinating.
When grilling or broiling, be careful not to overcook top round, as it can become dry and tough. Cook it to medium-rare and slice it thinly against the grain, just like you would with flank steak. However, be aware that the texture and flavor will be different, potentially lacking the intense beefy taste and tenderness of properly prepared flank steak.
What are Some Indicators to Tell Top Round and Flank Steak Apart Visually?
The easiest way to distinguish between the two is by looking at the grain. Flank steak has very long, distinct muscle fibers running the length of the steak. These fibers are easy to see and feel. It’s usually a wider and flatter cut compared to top round.
Top round, on the other hand, will appear more compact and rounded. The grain is still present, but it’s finer and less pronounced than in flank steak. The overall shape is generally thicker, and it may have more marbling (intramuscular fat) than flank steak, although both are considered lean cuts.
