London broil, a cut of beef often misunderstood and mistreated, can be transformed into a culinary masterpiece with the right technique and timing. While the name suggests a specific cut, it’s more accurately a cooking method applied to cuts like flank steak or top round. This guide focuses on mastering the cooking time for a 2-inch thick London broil, ensuring a tender and flavorful result every time. Forget tough, chewy disappointment – let’s unlock the secrets to perfect London broil.
Understanding the London Broil Cut
The term “London broil” itself is somewhat misleading. It doesn’t refer to one specific cut of meat. Instead, it describes a method of preparing and cooking a relatively lean, thicker cut of beef, typically either flank steak or top round. The key is to marinate the meat to tenderize it, and then to cook it quickly at high heat.
Flank steak is known for its pronounced grain, making it ideal for slicing against the grain after cooking, maximizing tenderness. Top round, being even leaner, benefits greatly from a marinade and precise cooking to avoid becoming overly dry. Both cuts, when prepared correctly, can deliver an excellent, economical steak experience.
A 2-inch thick London broil presents a unique challenge. Its thickness demands a slightly longer cooking time than its thinner counterparts, but it also offers the potential for a beautifully seared exterior and a perfectly pink interior. The goal is to achieve a balance between thoroughly cooked and optimally tender.
Factors Affecting Cooking Time
Several factors play crucial roles in determining the ideal cooking time for your 2-inch London broil. Ignoring these variables can easily lead to an overcooked or undercooked piece of meat.
Thickness of the Cut
Obviously, the thickness of the London broil is the primary factor in determining cooking time. A 2-inch thick cut will require significantly more time than a 1-inch cut to reach the desired internal temperature. The heat needs to penetrate further to cook the center properly.
Starting Temperature of the Meat
The initial temperature of the meat before cooking has a significant impact on the overall cooking time. Taking the London broil out of the refrigerator at least 30-60 minutes before cooking allows it to come closer to room temperature. This helps ensure more even cooking throughout the cut, reducing the risk of a cold center. If you cook it straight from the fridge, it will take longer to cook through, and the outside may overcook before the inside reaches the desired temperature.
Cooking Method
The method you choose for cooking – grilling, broiling, or pan-searing – will significantly influence the cooking time. Grilling and broiling, with their intense heat, typically require shorter cooking times than pan-searing. The intensity of the heat source directly affects how quickly the meat cooks.
Desired Doneness
Your personal preference for doneness – rare, medium-rare, medium, medium-well, or well-done – is a critical factor. Each level of doneness corresponds to a specific internal temperature, which dictates the required cooking time. Using a reliable meat thermometer is essential for achieving your desired level of doneness accurately.
Oven Temperature (if applicable)
If you are using an oven for part of the cooking process, the oven temperature will directly affect the cooking time. Higher oven temperatures will cook the meat faster.
Essential Tools for Perfect London Broil
Having the right tools is crucial for achieving consistent and delicious results.
Meat Thermometer
A reliable meat thermometer is non-negotiable. It’s the only way to accurately determine the internal temperature of the London broil and ensure it’s cooked to your desired doneness. Invest in a digital thermometer for quick and accurate readings.
Heavy-Bottomed Pan or Grill
For searing or grilling, use a heavy-bottomed pan or a well-heated grill. These surfaces provide even heat distribution, allowing for a proper sear and consistent cooking. A cast-iron skillet is an excellent choice for pan-searing.
Tongs
Use tongs to handle the London broil while cooking. Forks can pierce the meat, allowing valuable juices to escape and potentially drying out the steak.
Cutting Board
A sturdy cutting board is essential for slicing the cooked London broil against the grain. Choose a board that is large enough to accommodate the entire cut of meat.
Sharp Knife
A sharp knife is crucial for slicing the London broil thinly against the grain. A dull knife will tear the meat, resulting in uneven slices and a less appealing texture.

What is London Broil and why is the cooking time important?
London broil is a cut of beef, typically top round or flank steak, known for its lean and flavorful profile. It’s important to understand that “London broil” refers more to the cooking method than a specific cut. Due to its relatively thin and lean nature, overcooking London broil results in a tough and dry piece of meat, making the cooking time critical for achieving a tender and palatable result.
Accurate cooking times are essential for reaching the desired internal temperature, ensuring both safety and quality. Whether grilling, broiling, or pan-searing, precise timing, in conjunction with a reliable meat thermometer, is crucial for a successful London broil that is juicy and flavorful.
How does the thickness of the London broil affect cooking time?
The thickness of the London broil directly impacts the amount of time it needs to cook to reach a safe and desired internal temperature. A 2-inch thick London broil, compared to a thinner cut, will naturally require more cooking time to ensure the heat penetrates fully to the center without burning the exterior.
Thicker cuts benefit from slower cooking methods, which allow the heat to distribute more evenly. While high heat can quickly sear the outside, it may leave the inside undercooked. Therefore, adjusting cooking times based on thickness is paramount for achieving consistent doneness throughout the meat.
What internal temperature should a 2-inch London broil reach for different levels of doneness?
For a rare 2-inch London broil, aim for an internal temperature of 125-130°F (52-54°C). Medium-rare should reach 130-135°F (54-57°C). Medium doneness is achieved at 135-145°F (57-63°C), and medium-well is between 145-155°F (63-68°C).
Well-done, which is generally not recommended for London broil due to its potential for toughness, would be 155°F (68°C) and above. Always use a meat thermometer inserted into the thickest part of the steak to ensure accurate readings. Remember to account for carryover cooking, where the internal temperature rises slightly after removing the meat from the heat.
What are the best cooking methods for a 2-inch London broil?
Several cooking methods are suitable for a 2-inch London broil, each offering slightly different results. Grilling over high heat is a popular choice, providing a flavorful sear. Broiling in the oven is another quick option, mimicking the effects of grilling. Pan-searing, followed by a brief oven finish, allows for precise temperature control.
For a thicker cut like a 2-inch London broil, consider reverse searing for optimal results. This involves cooking at a low temperature in the oven until almost at the desired temperature, then searing at a high temperature in a pan or on the grill to create a flavorful crust. This ensures even cooking throughout.
How important is marinating a 2-inch London broil and how long should it marinate?
Marinating a London broil is highly recommended, especially for this leaner cut of beef, as it significantly enhances flavor and tenderness. The marinade helps break down tough muscle fibers and infuses the meat with moisture, resulting in a more palatable and enjoyable eating experience.
Ideally, marinate the London broil for at least 2 hours, but no more than 24 hours. Longer marinating times can actually cause the meat to become mushy. A good marinade should include an acid (like vinegar or lemon juice), oil, and a blend of herbs and spices to complement the beef’s natural flavors.
What role does resting the meat play after cooking a 2-inch London broil?
Resting the meat is a crucial step after cooking any steak, including London broil, and is particularly important for a cut of this size. During cooking, the juices within the meat are forced towards the center. Resting allows these juices to redistribute throughout the steak, resulting in a more tender and flavorful final product.
Allow the 2-inch London broil to rest for at least 10-15 minutes before slicing. Tent it loosely with foil to keep it warm without steaming it. This resting period prevents the juices from running out when you slice the meat, ensuring a more succulent and enjoyable eating experience.
How should a 2-inch London broil be sliced after cooking and resting?
Proper slicing is essential to maximizing the tenderness of London broil, particularly since it can be a tougher cut if not prepared correctly. Always slice the London broil against the grain, which means cutting perpendicular to the direction of the muscle fibers.
Identifying the direction of the grain is crucial; look for the lines running along the surface of the meat. Slicing against the grain shortens these fibers, making the meat easier to chew and more tender. Cut into thin slices, about 1/4 inch thick, for the best texture and flavor.
