If you’re a meat lover, you’ve probably heard of London broil and flank steak, two popular cuts of beef that are both lean and flavorful. But what happens when you need to substitute one for the other?

Can you use London broil in place of flank steak, or vice versa? Let’s explore the similarities and differences between these two cuts and find out.

What is London Broil?
London broil is actually a cooking method rather than a specific cut of meat. Traditionally, London broil refers to a flank steak that has been marinated, grilled or broiled, and then sliced against the grain. However, in some supermarkets, the term “London broil” may refer to top round steak or sirloin tip steak as well.

What is Flank Steak?
Flank steak is a long, thin cut of beef that comes from the lower chest of the cow. It’s known for its rich flavor and fibrous texture. Flank steak is often used in dishes like fajitas or stir-fries because it absorbs marinades well and cooks quickly.

Can You Substitute London Broil for Flank Steak?
The answer is yes, but with some caveats. Since London broil can refer to different types of beef cuts, it’s important to choose the right one when substituting for flank steak. If your recipe calls for flank steak specifically because of its texture or flavor profile, using a different cut like top round or sirloin tip may alter the taste and texture of your dish.

If you do decide to use London broil as a substitute for flank steak, keep in mind that they have different thicknesses and cooking times. London broil tends to be thicker than flank steak, so adjust your cooking time accordingly to avoid overcooking or undercooking.

How to Cook London Broil and Flank Steak
Both London broil and flank steak are best cooked quickly at high heat. To prepare either cut, start by marinating it for a few hours or overnight to add flavor and tenderness. Then, preheat your grill or broiler and cook the steak for 5-7 minutes per side, depending on the thickness of the cut.

For London broil, you can also sear it in a hot skillet on the stovetop before finishing it in the oven. This will give it a nice crust on the outside while keeping it juicy and tender on the inside.

So, can you substitute London broil for flank steak? Yes, but be mindful of the type of beef cut you’re using and adjust your cooking time accordingly. With proper preparation and cooking techniques, both cuts can be delicious in a variety of dishes.
