Flank steak is a popular cut of beef that is known for its rich flavor and tender texture. It is often used in a wide variety of dishes, from tacos to stir-fries, and can be cooked in a variety of ways.

However, one question that many people have when it comes to flank steak is what exactly constitutes a serving size. In this article, we’ll explore the answer to this question and provide some tips on how to properly portion your flank steak.

What Is Flank Steak?

Before we dive into the serving size of flank steak, let’s first define what exactly this cut of beef is. Flank steak comes from the abdominal muscles of the cow and is typically a long, flat cut that can be quite tough if not cooked properly. It is often marinated prior to cooking to help tenderize the meat and infuse it with flavor.

Serving Size

When it comes to determining the proper serving size for flank steak, there are a few factors that come into play. The first factor is the weight of the steak itself. A typical serving size of flank steak is around 3 ounces, which equates to about 85 grams.

However, it’s important to keep in mind that this serving size can vary depending on your individual dietary needs and preferences. For example, if you are following a high-protein diet or are an athlete looking to build muscle mass, you may need more protein than the average person and therefore may want to increase your serving size accordingly.

How To Portion Your Flank Steak

Now that we know what constitutes a typical serving size for flank steak, let’s talk about how to portion your steak properly. One easy way to do this is by using a food scale to weigh out your desired amount of meat.

If you don’t have access to a food scale, you can also estimate your serving size by using the palm of your hand. A serving size of flank steak should be roughly the size and thickness of your palm.

Cooking Tips

Once you have properly portioned your flank steak, it’s time to cook it up! Flank steak can be grilled, broiled, or pan-seared for optimal flavor and tenderness. It’s important to note that flank steak should be cooked to an internal temperature of at least 145°F (63°C) to ensure that it is safe to eat.

To help keep your flank steak tender and juicy, consider marinating it for a few hours prior to cooking. You can use a variety of marinades, from simple olive oil and garlic to more complex blends featuring soy sauce, citrus juice, and spices.


In conclusion, a typical serving size for flank steak is around 3 ounces or 85 grams. However, this serving size can vary depending on your individual dietary needs and preferences.

To properly portion your flank steak, use a food scale or estimate the size based on the palm of your hand. And when cooking your flank steak, remember to marinate it for optimal tenderness and safety!
