The world of steak can be surprisingly complex. With various cuts offering distinct flavors, textures, and cooking methods, it’s easy to feel overwhelmed when choosing the perfect piece of beef for your next meal. Among the many options, flank steak and skirt steak often cause confusion. Are they the same? Do they taste alike? Can they be used interchangeably in recipes? The short answer is no, they are not the same, but understanding their similarities and differences is key to mastering your grilling game. This comprehensive guide will delve into the nuances of flank and skirt steak, equipping you with the knowledge to confidently select and prepare these delicious cuts of meat.
Understanding the Anatomy: Where Do Flank and Skirt Steak Come From?
To truly appreciate the difference between flank and skirt steak, it’s crucial to understand their anatomical origins. Both cuts come from the abdominal area of the cow, but from distinct locations within that region.
Flank Steak: The Abdominal Muscle
Flank steak is cut from the abdominal muscles of the cow, specifically from the lower portion of the belly. This area is located further back on the animal than where skirt steak is located. Because these muscles are heavily worked, flank steak is a relatively lean cut with noticeable muscle fibers running lengthwise. This grain is a defining characteristic of flank steak and significantly impacts how it should be prepared and sliced.
Skirt Steak: The Diaphragm Difference
Skirt steak, on the other hand, comes from the diaphragm muscle of the cow. There are two types of skirt steak: inside skirt and outside skirt. Outside skirt steak is generally considered more flavorful and tender than inside skirt. It’s also significantly wider and thinner. The inside skirt is located inside the rib cage, while the outside skirt is located just outside of it. Like flank steak, skirt steak is also a hardworking muscle, contributing to its robust flavor.
Flavor Profile: A Tale of Two Steaks
While both flank and skirt steak boast intense beefy flavors, subtle distinctions exist. These differences largely stem from their fat content and muscle structure.
Flank Steak: Lean and Beefy
Flank steak has a bold, beefy flavor that is less intense than skirt steak. Its leaner profile means it doesn’t have the same level of marbling or fat content, resulting in a slightly drier texture if overcooked. However, its ability to absorb marinades makes it a versatile choice for a wide array of flavor combinations.
Skirt Steak: Intense and Savory
Skirt steak is celebrated for its intense, savory, and almost mineral-rich flavor. Its higher fat content compared to flank steak contributes to a richer, more succulent taste. The loose muscle fibers also allow it to readily absorb marinades, enhancing its flavor even further. The combination of intense flavor and tender texture makes it a favorite for dishes like fajitas and carne asada.
Texture and Tenderness: Key Considerations for Cooking
Texture is a critical factor in determining the overall dining experience. The unique muscle structures of flank and skirt steak result in different textures, requiring specific cooking techniques to maximize tenderness.
Flank Steak: A Grain of Truth
Flank steak is known for its pronounced grain. If not sliced properly, it can be quite chewy. To achieve optimal tenderness, it’s crucial to slice flank steak thinly against the grain. This shortens the muscle fibers, making them easier to chew and preventing a tough, stringy texture. Marinating flank steak is also highly recommended to help tenderize the meat and infuse it with flavor.
Skirt Steak: Naturally Tender(ish)
Skirt steak generally has a looser muscle structure compared to flank steak, making it naturally more tender. However, it can still become tough if overcooked. Like flank steak, skirt steak benefits from a quick, high-heat cooking method and should be sliced against the grain, although this is less critical than with flank steak due to its already tender nature.
Cooking Methods: Maximizing Potential
Both flank and skirt steak are best suited for high-heat cooking methods, such as grilling, pan-searing, or broiling. These techniques allow them to cook quickly, preventing them from drying out and becoming tough.
Flank Steak: The Marinade Master
Flank steak is a sponge for marinades. Its open grain allows it to readily absorb flavors, transforming it from a relatively plain cut into a flavor explosion. Marinating for at least 30 minutes, or preferably several hours, is highly recommended. Grilling or pan-searing over high heat is the ideal way to cook flank steak. Aim for medium-rare to medium doneness to maintain its tenderness. Remember to let it rest for several minutes before slicing against the grain.
Skirt Steak: The Quick Cook
Skirt steak is a champion of speedy cooking. Due to its thinner profile, it cooks very quickly over high heat. A quick sear on each side is often all that’s needed to achieve a delicious medium-rare or medium doneness. Be careful not to overcook it, as it can become tough. Skirt steak also benefits from marinating, although it’s not as essential as with flank steak. Its inherent flavor and tenderness make it delicious even with minimal seasoning.
Visual Cues: How to Tell Them Apart at the Butcher Shop
Identifying flank and skirt steak at the butcher shop can be tricky, especially for the untrained eye. However, several visual cues can help you distinguish between the two.
Flank Steak: Look for the Grain
Flank steak is typically a wide, flat cut of meat with a very visible and pronounced grain running lengthwise. It tends to be thicker than skirt steak and has a rectangular shape. The surface may appear slightly rougher compared to the smoother surface of skirt steak. The color can range from a bright red to a deeper, more purplish-red.
Skirt Steak: Thin and Wide
Skirt steak is usually thinner and wider than flank steak. It has a looser muscle structure and a less defined grain, although faint lines can still be visible. It often has a slightly irregular shape. The outside skirt steak is noticeably wider than the inside skirt steak. The color is typically a vibrant red.

What are the key differences in texture and taste between flank steak and skirt steak?
Flank steak is known for its relatively lean and slightly chewy texture. It has a pronounced grain that runs lengthwise, requiring slicing against the grain to maximize tenderness. The flavor of flank steak is often described as robust and beefy, making it a great choice for marinades and bolder seasonings.
Skirt steak, on the other hand, is significantly more tender and has a looser texture compared to flank steak. Its flavor is equally intense, perhaps even slightly richer and more “beefy” due to its higher fat content within the muscle fibers. It also benefits from marinades, but its inherent tenderness allows it to be cooked quickly and still remain enjoyable.
Which cut is better for grilling, and why?
Both flank steak and skirt steak are excellent choices for grilling, but skirt steak tends to excel slightly due to its higher fat content. This fat renders during the grilling process, keeping the steak moist and adding to its flavorful char. Its thinner profile also allows it to cook quickly over high heat, achieving a desirable sear without overcooking the inside.
Flank steak, while also grill-friendly, requires a bit more attention to prevent it from drying out. It’s crucial to avoid overcooking flank steak, and a marinade can help keep it juicy and flavorful during grilling. Careful monitoring of the internal temperature and slicing against the grain are key to a successful grilled flank steak.

Skirt steak generally requires a shorter cooking time than flank steak due to its thinner profile. Cooking skirt steak over high heat for just a few minutes per side is usually sufficient to achieve medium-rare or medium doneness. Overcooking skirt steak can lead to toughness, so quick cooking is crucial.
Flank steak, being thicker, needs slightly longer on the grill or in a pan. While high heat is still recommended for searing, it’s essential to monitor the internal temperature to avoid overcooking. Allow approximately 4-6 minutes per side for medium-rare, adjusting based on the thickness of the steak and desired doneness.
Which cut is more versatile for different cooking methods beyond grilling?
While both are typically grilled, flank steak’s thicker cut makes it somewhat more versatile for other cooking methods. It can be pan-seared, broiled, or even cooked sous vide before being seared for a final crust. Its ability to hold its shape slightly better than skirt steak also makes it suitable for stuffing and rolling.
Skirt steak, due to its thinner and more irregular shape, is best suited for quick-cooking methods like stir-frying or searing in a hot pan. Its tenderness makes it ideal for fajitas and tacos, where it can be easily sliced into thin strips after cooking. While less commonly used in other preparations, it can still be a delicious option for recipes requiring thinly sliced, flavorful beef.
Which cut is generally more economical to purchase?
Generally, skirt steak tends to be slightly more expensive than flank steak. This price difference can vary based on location, butcher shop, and the specific grade of the meat. The increased demand for skirt steak in popular dishes like fajitas often contributes to its higher price point.
Flank steak, being a relatively lean and larger cut, is usually more readily available and therefore slightly more budget-friendly. While the price difference may not always be significant, those looking for a more economical option will often find flank steak to be the better choice.
How should I marinate flank steak and skirt steak to maximize flavor and tenderness?
Both flank steak and skirt steak benefit greatly from marinating, but the ideal marinade composition can vary slightly. For flank steak, which can be a bit tougher, a marinade with acidic components like citrus juice or vinegar is beneficial for tenderizing the meat.

Skirt steak, being naturally more tender, can handle a wider range of marinade flavors. While acidic components are still helpful, you can focus more on bolder and spicier flavors like chili powder, cumin, lime juice, and cilantro. The thinner cut also allows for quicker marinade absorption, so shorter marinating times are generally sufficient.
How do you properly slice flank steak and skirt steak for serving?
The key to serving both flank steak and skirt steak is slicing them against the grain. The grain refers to the direction of the muscle fibers, which are clearly visible on both cuts. Slicing against the grain shortens these fibers, making the meat significantly more tender and easier to chew.
For flank steak, identify the long, prominent grain running lengthwise. Cut perpendicular to this grain, slicing the steak thinly on a slight bias. For skirt steak, the grain is often less obvious but still present. Similar to flank steak, slice the skirt steak thinly against the grain after cooking, ensuring each slice is tender and easy to enjoy.
