London Broil is a culinary term that refers to both a cooking method and a specific cut of meat, typically derived from the flank or round cuts of beef. The name can be somewhat misleading, as it does not refer to a specific cut of meat but rather to the preparation technique that involves marinating the meat and then cooking it at high temperatures. Traditionally, London Broil is marinated to enhance its flavor and tenderness, then grilled or broiled quickly to achieve a desirable crust while keeping the interior juicy and medium-rare.
The result is a flavorful, tender piece of meat that can be sliced thinly against the grain for serving. The origins of London Broil are somewhat murky, with various theories about how it got its name. Some suggest that it was popularized in the United States in the mid-20th century, while others believe it may have roots in British cuisine.
Regardless of its origins, London Broil has become a staple in American households, particularly for those who enjoy grilling and outdoor cooking. The versatility of this dish allows it to be served in various ways, from sandwiches to salads, making it a favorite among home cooks and chefs alike.

The Sous Vide Cooking Method
Sous vide, which translates from French to “under vacuum,” is a cooking technique that involves sealing food in a vacuum-sealed bag and immersing it in a water bath at a precisely controlled temperature. This method allows for even cooking throughout the food item, ensuring that it reaches the desired doneness without the risk of overcooking. The sous vide process can take several hours, depending on the type of food being prepared, but the results are often worth the wait.
The technique has gained popularity among both professional chefs and home cooks due to its ability to produce consistently high-quality results. One of the key advantages of sous vide cooking is its precision. Unlike traditional cooking methods that rely on guesswork and fluctuating temperatures, sous vide allows for exact temperature control.
This means that proteins can be cooked to the exact level of doneness desired—whether that’s rare, medium, or well-done—without the risk of drying out or becoming tough. Additionally, because the food is sealed in a bag, it retains moisture and flavor, resulting in a more succulent final product. This method is particularly beneficial for tougher cuts of meat, which can become tender and flavorful when cooked slowly at low temperatures.
Why Sous Vide is Perfect for London Broil

Sous vide is an ideal cooking method for London Broil due to its ability to transform tougher cuts of meat into tender, flavorful dishes. The flank and round cuts typically used for London Broil can be quite lean and may require careful cooking to avoid toughness. By using sous vide, cooks can ensure that these cuts are cooked evenly and gently over an extended period, allowing the connective tissues to break down and resulting in a tender texture that is often difficult to achieve through traditional cooking methods.
Moreover, sous vide cooking allows for enhanced flavor infusion through marination. When meat is vacuum-sealed with a marinade, the flavors penetrate deeply into the meat during the cooking process. This results in a more flavorful dish compared to traditional marinating methods where some of the marinade may wash away during cooking.
The combination of precise temperature control and flavor infusion makes sous vide an excellent choice for preparing London Broil, ensuring that each bite is both tender and packed with flavor.
Choosing the Right Cut of Meat
| Meat Cut | Best Cooking Method | Recommended Internal Temperature |
|---|---|---|
| Ribeye | Grilling, Pan-Searing | Medium Rare: 130-135°F |
| Tenderloin | Roasting, Grilling | Medium Rare: 130-135°F |
| Chuck Roast | Braising, Slow Cooking | Well Done: 160-165°F |
| Pork Shoulder | Smoking, Braising | Well Done: 160-165°F |
Selecting the right cut of meat is crucial when preparing London Broil using sous vide. Traditionally, flank steak is the most common choice due to its rich flavor and relatively low cost. Flank steak comes from the abdominal muscles of the cow and has long muscle fibers that can be tough if not cooked properly.
However, when cooked sous vide, flank steak becomes incredibly tender while retaining its robust beefy flavor. Another option for London Broil is top round steak, which is cut from the rear leg of the cow. This cut is leaner than flank steak but can also benefit from sous vide cooking to achieve tenderness.
Top round has a slightly different texture and flavor profile compared to flank steak but can still yield delicious results when prepared correctly. When choosing your cut, look for well-marbled pieces with some fat content, as this will contribute to flavor and moisture during cooking.
Seasoning and Marinating Tips
Seasoning and marinating are essential steps in preparing London Broil, especially when using sous vide. A good marinade not only enhances flavor but also helps to tenderize the meat. Common ingredients for marinades include soy sauce, garlic, olive oil, vinegar, and various herbs and spices.
For instance, a simple marinade could consist of soy sauce mixed with minced garlic, black pepper, and a splash of balsamic vinegar. This combination provides a savory depth that complements the natural flavors of the beef. When marinating London Broil for sous vide cooking, it’s important to allow enough time for the flavors to penetrate the meat.
Ideally, marinate for at least 4 hours or up to 24 hours for maximum flavor infusion. After marinating, ensure that you remove excess marinade before sealing the meat in a vacuum bag; this prevents excess liquid from diluting flavors during cooking. Additionally, consider adding fresh herbs or aromatics directly into the vacuum bag with the meat for an extra layer of flavor during the sous vide process.
Setting Up the Sous Vide Machine

Setting up your sous vide machine is a straightforward process but requires attention to detail to ensure optimal results. Begin by filling a large pot or container with water—this will serve as your water bath. The amount of water needed will depend on the size of your sous vide machine and how much food you plan to cook.
Once filled, attach your immersion circulator according to the manufacturer’s instructions and set it to your desired cooking temperature. Before placing your vacuum-sealed London Broil into the water bath, ensure that your sous vide machine is preheated to the correct temperature. This step is crucial because placing cold food into an unheated bath can lead to uneven cooking and extended cooking times.
Once your machine has reached the desired temperature, carefully submerge your sealed bag of meat into the water bath, ensuring that it is fully submerged and not floating on the surface. You may need to use weights or clips to keep it submerged if necessary.
Cooking Time and Temperature
The cooking time and temperature for sous vide London Broil can vary depending on personal preference regarding doneness as well as the thickness of the cut being used. For flank steak or top round steak cooked to medium-rare (about 130°F or 54°C), a cooking time of 2 to 4 hours is generally recommended. This range allows enough time for the meat to become tender while ensuring it does not overcook.
For those who prefer their London Broil cooked medium (about 140°F or 60°C), you can increase the temperature slightly while maintaining similar cooking times. If you opt for well-done (around 160°F or 71°C), you may want to extend the cooking time up to 6 hours; however, be cautious as this can lead to drier meat if overcooked beyond this point. The beauty of sous vide lies in its forgiving nature; even if you leave it in longer than intended within reason, it will still yield better results than traditional methods.
Searing the London Broil
After your London Broil has finished cooking in the sous vide bath, searing is an essential step that adds texture and enhances flavor through caramelization. To achieve a perfect sear, remove the vacuum-sealed bag from the water bath and take out the meat carefully. Pat it dry with paper towels; moisture on the surface can hinder browning during searing.
Heat a cast-iron skillet or heavy-bottomed pan over high heat until it’s smoking hot—this ensures a good sear without overcooking the interior of the meat. Add a small amount of oil with a high smoke point, such as grapeseed or avocado oil, then place your London Broil in the pan. Sear each side for about 1-2 minutes until a rich brown crust forms.
If desired, you can add butter and fresh herbs like thyme or rosemary during this process for added flavor.
Serving and Pairing Suggestions
Once your London Broil has been seared to perfection, it’s time to slice and serve it. Always remember to cut against the grain; this technique shortens muscle fibers and results in more tender bites. Thin slices are ideal for serving as they allow diners to enjoy both texture and flavor fully.
London Broil pairs beautifully with various sides and accompaniments. Classic options include roasted vegetables or mashed potatoes; however, consider serving it with a fresh salad or grilled asparagus for a lighter meal option. Additionally, sauces such as chimichurri or garlic herb butter complement the beef’s rich flavors wonderfully.
For those looking for something heartier, consider serving it in sandwiches or tacos topped with fresh salsa or pickled onions.
Tips for Leftovers
Leftover London Broil can be just as delicious as when it was first served if stored properly. After slicing any remaining meat, store it in an airtight container in the refrigerator for up to three days. To maintain moisture and flavor when reheating leftovers, consider using gentle methods such as warming them in a skillet over low heat or briefly reheating them in a sous vide bath set at a lower temperature than originally cooked.
Another creative way to use leftover London Broil is by incorporating it into various dishes such as stir-fries, salads, or pasta dishes. Thinly sliced beef can add protein and flavor to grain bowls or be used as a filling for quesadillas or wraps. The versatility of this dish ensures that leftovers do not go to waste but instead become an opportunity for new culinary creations.
