Skirt steak. The name itself conjures up images of sizzling fajitas, carne asada tacos, and perfectly grilled strips of beef. But what exactly is skirt steak? Where does it come from on the cow, and what makes it so uniquely delicious? This article will unravel the mysteries surrounding this popular cut of meat, exploring its anatomy, characteristics, cooking methods, and culinary applications.
Understanding the Anatomy of Skirt Steak
To truly understand skirt steak, we need to delve into the anatomy of the beef carcass. This cut isn’t a single, homogenous piece of meat; rather, there are two distinct types of skirt steak, each originating from different areas of the animal. These are the inside skirt and the outside skirt.
Inside Skirt Steak
The inside skirt steak comes from the plate section of the cow, specifically from the diaphragm muscle. This muscle is located inside the abdominal cavity, attached to the ribs. Because of its location, the inside skirt is typically thinner and wider than its outside counterpart. It’s also known for being quite flavorful, though some find it slightly less tender.
Outside Skirt Steak
The outside skirt steak is prized for its superior tenderness and robust beefy flavor. It comes from the diaphragm muscle outside the rib cage, hence the name. This piece is typically shorter and thicker than the inside skirt, possessing a more uniform shape. Its location and composition contribute to its desirable texture.
Key Characteristics of Skirt Steak
Regardless of whether you’re dealing with inside or outside skirt, both share characteristics that make them stand out among other cuts of beef. Understanding these traits is crucial for proper preparation and cooking.
Grain and Texture
Perhaps the most defining characteristic of skirt steak is its very prominent grain. The muscle fibers run lengthwise down the cut, making them easily visible. This coarse grain is directly linked to the steak’s tendency to become tough if overcooked. However, when prepared correctly, this same grain contributes to its ability to absorb marinades and deliver intense flavor.
Flavor Profile
Skirt steak is known for its intensely beefy flavor. This richness stems from the muscle fibers and the presence of intramuscular fat. The flavor is often described as bold, slightly mineral-like, and very satisfying.
Fat Content
Skirt steak isn’t heavily marbled like a ribeye, but it does possess a good amount of intramuscular fat, which contributes to its flavor and moisture. Some of the fat may be visible on the surface, and trimming is generally recommended to prevent excessive flare-ups during grilling.
Thickness and Size
As mentioned earlier, inside and outside skirt steaks differ in thickness and size. Inside skirts are typically thinner and wider, while outside skirts are thicker and narrower. The thickness impacts cooking time, with thinner inside skirts cooking more quickly.
Cooking Methods for Skirt Steak
Skirt steak’s unique characteristics demand specific cooking techniques to maximize its potential. The key is to cook it quickly over high heat to achieve a beautiful sear while keeping the inside tender.
Grilling
Grilling is arguably the most popular method for cooking skirt steak. The high heat sears the outside, creating a flavorful crust, while the inside remains juicy. It’s essential to preheat the grill to a high temperature and cook the steak for only a few minutes per side, depending on thickness. Using a meat thermometer can help ensure it reaches the desired level of doneness.
Pan-Searing
Pan-searing is another excellent option, especially when outdoor grilling isn’t feasible. Use a heavy-bottomed skillet, preferably cast iron, and get it screaming hot before adding the steak. Sear for a few minutes per side, achieving a similar result to grilling. Make sure to use a high smoke point oil, such as avocado or grapeseed oil.
Broiling
Broiling offers a similar high-heat cooking method, allowing for a quick and even sear. Position the steak close to the broiler and watch it carefully to prevent burning. This method requires close attention, but it can produce excellent results.
Sous Vide (and Sear)
For ultimate precision, consider using the sous vide method. Cook the skirt steak in a water bath at your desired temperature for a few hours, then sear it quickly in a hot pan or on a grill to develop a crust. This ensures consistent doneness throughout the steak.
Marinades and Flavor Pairings
Skirt steak benefits greatly from marinating. The marinade not only adds flavor but also helps tenderize the meat. The best marinades often include acidic ingredients like citrus juice or vinegar, which help break down the tough muscle fibers.
Common Marinade Ingredients
Common ingredients found in skirt steak marinades include:
- Citrus juices (lime, orange)
- Soy sauce
- Garlic
- Onion
- Chili peppers
- Herbs (cilantro, oregano)
- Vinegar (red wine, balsamic)
- Olive oil
Flavor Pairings
Skirt steak’s bold flavor pairs well with a variety of ingredients and cuisines. It’s a staple in Mexican cuisine, particularly in dishes like fajitas and carne asada. It also works well with Asian-inspired flavors, such as ginger, soy sauce, and sesame oil. The versatility of skirt steak makes it a great option for experimenting with different flavor combinations.
Slicing and Serving Skirt Steak
Proper slicing is crucial for maximizing the tenderness of skirt steak. Remember that prominent grain we talked about? The key is to slice the steak against the grain. This shortens the muscle fibers, making them easier to chew.
Slicing Against the Grain
Locate the direction of the muscle fibers and slice perpendicular to them. This will create shorter, more tender pieces of meat.
Serving Suggestions
Skirt steak is incredibly versatile and can be used in a variety of dishes. Here are a few ideas:
- Fajitas: Slice the steak into strips and serve with sautéed bell peppers and onions, tortillas, and your favorite toppings.
- Carne Asada Tacos: Marinate the steak, grill it to perfection, and chop it up for delicious carne asada tacos.
- Steak Salad: Top a bed of greens with grilled skirt steak, vegetables, and a flavorful vinaigrette.
- Steak Sandwiches: Use skirt steak as the filling for a hearty and satisfying steak sandwich.
Purchasing and Storing Skirt Steak
When buying skirt steak, look for pieces that are a vibrant red color and have a good amount of marbling. Avoid steaks that look dry or have a greyish tinge.
Where to Buy
Skirt steak can be found at most supermarkets and butcher shops. Specialty butcher shops often offer higher-quality cuts.
Storage
Store skirt steak in the refrigerator for up to three days. For longer storage, freeze it in an airtight container or freezer bag. Be sure to properly thaw the steak in the refrigerator before cooking.
Skirt Steak vs. Flank Steak
Skirt steak is often confused with flank steak, and while both are flavorful and relatively lean, they are distinct cuts.
Key Differences
Here’s a table summarizing the key differences:
| Feature | Skirt Steak | Flank Steak |
|——————-|————————————-|————————————-|
| Location | Plate (Inside & Outside Diaphragm) | Abdominal Muscles |
| Thickness | Thinner | Thicker |
| Grain | More Pronounced | Less Pronounced |
| Flavor | More Intense, Beefy | Slightly Less Intense, Beefy |
| Tenderness | Can be Tough if Overcooked | Can be Tough if Overcooked |
| Cooking Time | Shorter | Longer |
| Best For | Fajitas, Carne Asada | London Broil, Steak Rolls |
While both require slicing against the grain, flank steak is generally thicker and benefits from slightly longer cooking times. The flavor profiles are similar, but skirt steak has a more intense beefy taste.

By understanding its anatomy, characteristics, and proper cooking techniques, you can unlock the full potential of this flavorful cut and create memorable meals. Whether you’re grilling up fajitas, preparing carne asada tacos, or simply searing a steak for a weeknight dinner, skirt steak is a guaranteed crowd-pleaser.
What exactly is skirt steak and where does it come from?
Skirt steak is a thin, flavorful cut of beef taken from the diaphragm muscle of the cow. Specifically, there are two types: the inside skirt and the outside skirt. The outside skirt is considered more desirable because it’s wider, thicker, and more tender, although it’s also more expensive and harder to find.
The inside skirt comes from inside the abdominal wall, while the outside skirt comes from outside the abdominal wall, running along the ribs. Both cuts are known for their strong beefy flavor and loose muscle fibers, which make them ideal for quick cooking methods like grilling and searing.
What’s the difference between inside and outside skirt steak?
The primary difference lies in the location on the animal and the resulting size and tenderness. Outside skirt steak, being located on the outside of the abdominal wall, is generally wider and thicker, offering a slightly more tender texture. This makes it often the preferred choice for fajitas or grilling whole.
Inside skirt steak, taken from the inner abdominal wall, is thinner and narrower. While still flavorful, it can be tougher than the outside skirt steak if not properly marinated or cooked. Due to its smaller size, it often benefits from being rolled or stuffed before cooking.
Why is skirt steak so flavorful?
Skirt steak’s intense flavor stems from its location and muscle structure. The diaphragm muscle is constantly working, which contributes to its well-developed muscle fibers and rich, beefy taste. This constant use results in a deeper and more pronounced flavor profile compared to less active muscles.
Additionally, skirt steak’s relatively thin structure allows for maximum surface area exposure during cooking. This increased exposure leads to greater caramelization and Maillard reaction, enhancing the savory and umami notes of the beef, resulting in a uniquely satisfying flavor.
What are the best ways to cook skirt steak?
Due to its thinness, skirt steak is best cooked quickly over high heat. Grilling or searing in a hot skillet are popular methods to achieve a beautiful sear and flavorful crust while keeping the inside tender. The key is to avoid overcooking, as it can become tough.
Marinating skirt steak is highly recommended, as it helps tenderize the meat and infuse it with additional flavors. Marinades with acidic ingredients like citrus juice or vinegar help break down the muscle fibers. After cooking, always slice the steak against the grain to maximize tenderness.
What are some popular dishes that use skirt steak?
Skirt steak is perhaps most famously used in fajitas, where it’s grilled or seared, then thinly sliced and served in tortillas with peppers, onions, and other toppings. Its robust flavor stands up well to bold seasonings and pairs perfectly with the other ingredients.
Beyond fajitas, skirt steak is also excellent for tacos, stir-fries, and steak salads. Its quick cooking time and intense flavor make it a versatile ingredient for a variety of dishes. It can even be used in sandwiches or served as a standalone steak with a simple side dish.
How do I know if skirt steak is cooked properly?
The best way to determine doneness is with a meat thermometer. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C). Medium should be around 135-145°F (57-63°C). Remember that the temperature will rise slightly after removing the steak from the heat.
Visually, a properly cooked skirt steak should have a nicely browned or seared exterior and a slightly pink interior. Avoid overcooking, as it will become tough and dry. If you don’t have a thermometer, a gentle press on the steak can indicate doneness; it should feel slightly firm but still have some give.
Where can I buy skirt steak, and what should I look for?
Skirt steak can typically be found at most well-stocked grocery stores and butcher shops. Look for meat that is a deep red color and has good marbling (flecks of fat within the muscle). This marbling will contribute to the flavor and tenderness of the steak.
When selecting skirt steak, avoid any pieces that are discolored or have an off-putting smell. Also, check the thickness of the steak; ideally, you want a relatively uniform thickness for even cooking. If you can choose between inside and outside skirt, the outside skirt is generally preferred for its slightly more tender texture, but the inside skirt is a perfectly acceptable alternative if properly prepared.
