London broil and flank steak are two popular cuts of beef that are commonly used in various recipes. They have a lot of similarities, including their lean meat and affordable prices, which make them a favorite among many home cooks.

However, can you substitute London broil for flank steak? Let’s find out.

What is London Broil?

London broil is not actually a specific cut of beef. Instead, it’s a cooking method that involves marinating and broiling a top round steak or flank steak.

The marinade typically consists of oil, acid (such as vinegar or lemon juice), herbs, and spices. After marinating for several hours or overnight, the steak is broiled in the oven or grilled on high heat until it’s cooked to the desired level of doneness.

What is Flank Steak?

Flank steak is a lean and flavorful cut of beef that comes from the abdominal muscles of the cow. It’s long and flat with a pronounced grain pattern that makes it perfect for grilling or pan-searing. Flank steak is known for its intense beefy flavor and slightly Chewy texture, which makes it great for dishes like fajitas, stir-fries, and salads.
