If you’re a meat lover, you know that choosing the right cut of beef can make all the difference in the taste and texture of your dish. Two popular cuts of beef that are often compared are flank steak and sirloin.

But what if you don’t have one or the other on hand? Can you substitute one for the other? Let’s take a closer look.

What is Flank Steak?

Flank steak is a lean, flavorful cut of beef that comes from the abdominal muscles of the cow. It’s long, flat, and usually about 1 inch thick.

Because it’s so lean, flank steak can be tough if not cooked properly. It’s best when cooked quickly at high heat and sliced thinly against the grain.

What is Sirloin?

Sirloin is another popular cut of beef that comes from the rear back portion of the cow, just above the flank. It’s a bit fattier than flank steak and has a richer flavor. There are different types of sirloin cuts including top sirloin and bottom sirloin.

Can I Replace Flank Steak With Sirloin?

The short answer is yes, you can replace flank steak with sirloin in most recipes. However, there are some things to keep in mind.

  • Cooking Method: Flank steak and sirloin require different cooking methods due to their different textures. Flank steak should be cooked quickly at high heat while sirloin can handle longer cooking times.
  • Cut: If your recipe calls for thin slices of meat, such as for fajitas or stir-fry, then sirloin may not be the best substitute as it doesn’t slice as thinly as flank steak.
  • Flavor: Keep in mind that sirloin has a richer flavor than flank steak. If you’re looking for a leaner cut of meat, sirloin may not be the best choice.
