Is London Broil the Same as Roast Beef?

By Michael Ferguson

London broil and roast beef are two different cuts of meat, despite their similarities in appearance and texture. The confusion between the two cuts is understandable, as they can both be prepared in similar ways. However, there are distinct differences that set them apart.

What is London Broil

London broil refers to a cooking method where a cut of beef such as flank steak or top round steak is marinated, grilled or broiled to medium-rare or medium doneness, and then sliced thinly against the grain. The marinade typically includes acidic ingredients like vinegar or lemon juice, along with spices and herbs. This method gives the meat a tender and juicy flavor that is perfect for sandwiches, salads, or eaten on its own.

What is Roast Beef

Roast beef refers to a cut of meat that comes from the round primal cut of beef. It can be bone-in or boneless and is typically slow-roasted in an oven until it reaches an internal temperature of 135°F (57°C) for medium-rare doneness. The roast beef can then be thinly sliced for sandwiches or served as a main dish with gravy and vegetables.

Differences Between London Broil and Roast Beef

The main differences between London broil and roast beef are:

  • Cut of meat: London broil can be made using different cuts like flank steak or top round steak whereas roast beef specifically uses the round primal cut of beef.
  • Cooking method: London broil involves grilling or broiling at high heat after marinating while roast beef is slow-roasted in an oven.
  • Texture: London broil is typically sliced thinly against the grain and has a tender and juicy texture, while roast beef can be served in larger slices and has a firmer texture.

Conclusion

In conclusion, London broil and roast beef are two different cuts of meat that are prepared using different methods. While London broil involves grilling or broiling a marinated cut of beef, roast beef is slow-cooked in an oven until it reaches medium-rare doneness. The next time you’re at the butcher shop or planning a meal, keep in mind the differences between these two cuts of meat to ensure you’re getting the flavor and texture you desire.
