Skirt Steak vs Flank Steak

Acabonac Farms |

When it comes to beef cuts, skirt steak and flank steak are often confused with one another. Don’t be too hard on yourself though, it makes sense as to why. They’re both thinner cuts of beef perfect for grilling and marinating, oftentimes used interchangeably. However, they each bring some unique qualities to the table, and in this article, you’re going to learn the important differences between them, and when you might want one over the other.  

Skirt steak, harvested from the cow's diaphragm, sports a long, flat shape and has a real knack for absorbing marinades, making it the star of dishes like fajitas. Its robust flavor and slightly tougher texture mean it benefits from some tender loving care in the form of a good marinade.

Flank steak, on the other hand, is cut from the lower abdominal area, making it leaner and thicker than its skirt counterpart. It has a very pronounced grain, which is a highway map for slicing: cut against it, and you’re rewarded with tender bites; slice with it, and you might find yourself chewing longer than you'd like.

Recognizing the subtle differences, and understanding how to prepare each cut properly, can elevate your dishes significantly. For those looking to source the best in grass-fed beef, Acabonac Farms offers both cuts, ensuring high quality meat without unwanted additives or chemicals, unmatched flavor, and ethical sustainable sourcing. Knowing the difference between skirt and flank steak will have you holding the title of grillmaster in no time.

Key Takeaways

  • Both skirt and flank steaks are known for their rich flavor and ability to absorb marinades, making them two of the most popular choices for grilling enthusiasts.
  • Skirt steak is very thin, making it ideal for quick cooking and has a stronger beefy flavor. Flank steak has a more mild taste suitable for many dishes, but comes with a prominent grain which means proper slicing is needed to maximize tenderness.
  • Understanding how to properly prepare and cook each cut - considering their unique textures and flavors - can significantly enhance your results.

What is Skirt Steak?

Skirt steak is a cut of beef that comes from the diaphragm muscles of the cow, and is one of the top cuts of steak at Acabonac Farms. It is known for its long, flat shape and is located near the cow's belly, which results in a very thin cut that has a lot of flavor but can also be quite tough if overcooked. Visually, skirt steak is recognizable by its thin, elongated appearance, with a grain that runs across its length. Other names that it goes by are “entraña" in Spanish-speaking countries, Romanian steak, Philadelphia steak, or Arrachera.

Typical Uses for Skirt Steak

Skirt steak is a favorite in many dishes across various cuisines, particularly known for its role in Mexican fajitas. It also shines in stir-fries, sandwiches, and as a standalone entrée, often marinated and grilled to bring out its full flavor. Some of the main reasons you might want to want to feature skirt steak in your next meal are:

Marinade Absorption: Because of its loose muscle fibers, skirt steak is perhaps the best cut for absorbing the flavors of marinades.

Quick Cooking: Its thinness allows for fast cooking, ideal for high-heat methods like grilling.

Versatility: Excellent in a variety of dishes, from casual barbecues to gourmet preparations.

Cost-Effectiveness: Generally more affordable than premium cuts, making it a great choice for flavorful meals on a budget.

What is Flank Steak?

Flank steak is a lean and flavorful primal cut of beef that comes from the abdominal muscles or lower chest of the cow, similar to flap steak. Unlike skirt steak, flank steak is thicker and wider, but it also has a noticeable grain running across it, making it easy to identify. This cut is relatively flat and long, and is known for its texture that becomes very tender when sliced properly (against the grain).

In most English-speaking countries, ‘flank steak” is this cut’s primary name. However, in French cuisine, it is often referred to as "bavette." In Latin America, particularly in Brazil, it's called "fraldinha”.

Typical Uses for Flank Steak

Flank is excellent for grilling, broiling, or stir-frying. This cut shines in dishes that utilize marination before cooking, as the flank readily absorbs flavors and becomes more tender during the process. When cut against its prominent grain, flank steak is used in many of the same dishes as skirt steak. It is a terrific choice for use in salads, fajitas, and sandwiches too! Flank steak is also particularly popular in Asian cooking, especially in Chinese and Thai cuisines.

Many of the same advantages from skirt steak come with this cut, including its versatility, cost-effectiveness, and quick cooking time. However there are some distinct advantages:

  • Leanness: If you’re looking for a lower fat meal, flank steak offers less marbling than skirt steak.
  • Tenderness: While both cuts are tender when handled and prepared correctly, flank steak becomes even more notably tender than skirt when cut against its prominent grain. 
  • Uniform Thickness: Flank is easier to work with than skirt steak because of its consistent thickness throughout the cut.

Which is Fattier: Skirt Steak or Flank Steak?

Skirt steak generally contains more fat. The marbling in skirt steak is one of the advantages of the cut, as the fat renders during high heat cooking methods and coats instills the meat with a richer flavor. However, this fat content can be seen as a downside for those who are more health conscious.

Is Flank or Skirt Steak Better For Fajitas?

For fajitas, skirt steak is traditionally the preferred choice. Skirt steak's texture, when marinated and cooked quickly at high heat, becomes ideally tender and flavorful, which is what you want when preparing fajitas. While flank steak can also be used and yields tasty results, skirt steak holds the edge here.

Can You Replace Flank Steak with Skirt Steak?

Replacing flank steak with skirt steak is generally acceptable in many recipes, especially in stir-fries or grilled meals. However, it's important to consider the difference in flavor. Skirt steak has a much more beefy taste, which can be a pro or con depending on who you ask. Flank steak is usually preferred in Asian cuisine, for example, because it is more mild - allowing the other ingredients and flavors to shine.

How to Cook Flank Steak and Skirt Steak

Both cuts respond well to similar cooking methods and involve almost identical preparation techniques (which is why they are so often interchangeable in recipes). They should be marinated for the best results, as they’re thin profile maximizes flavor absorption and allows marinade to effectively break down the muscle fibers and tenderize the meat. High heat, quick cooking methods like grilling and pan-searing are the best options for both cuts to get a delicious sear/char on the outside while locking in flavor on the inside. 

Make sure your pan or grill is very hot before placing your meat on it. For tender grass-fed beef, cooking should only take 3-4 minutes per side when grilling or pan-searing. If your temperature is too low, you’ll miss out on the sear and have to expose the meat to heat for a longer time, which will yield chewy and tough results. For a more guaranteed tender result, you can also slow-cook or braise flank or skirt steak. This method is excellent for breaking down tougher fibers - especially with flank steak. When finished cooking, always slice your steak against the grain as it cuts through the muscle fibers and increases tenderness.

Key Differences in Cooking Approaches

While the majority or the cooking process for flank and skirt steak is the same, it is important to remember these tips for each respective steak:

Skirt Steak: Because it is thinner than flank steak, it is much easier to overcook. Keep a watchful eye on your meat and remove immediately after a sear has established. 3-4 minutes on each side is the recommended cooking time for both cuts, but shoot closer to 3 minutes for skirt steak. 

Flank Steak: Being slightly thicker than skirt steak, flank steak does not absorb marinades as quickly. When marinating flank steak, try to do so overnight to get the absolute best results. Also, while both cuts need to be sliced against the grain after cooking, it is particularly important for flank steak as it has tighter muscle fibers that need to be separated by slicing (incorrectly sliced flank steak will be tougher than incorrectly sliced skirt steak).
