Choosing the right cut of beef can be daunting, especially with so many options available at the butcher counter. Two cuts that often cause confusion are skirt steak and flap steak. Both are known for their robust flavor and affordability, but understanding their differences in texture, location on the animal, and best cooking methods is key to achieving culinary success. Let’s delve into the specifics of each cut to help you make the best choice for your next meal.
Understanding Skirt Steak
Skirt steak is a thin, flavorful cut of beef taken from the diaphragm muscle of the cow. This muscle is located in the plate section, which is found below the short ribs. Due to its location, it works hard, resulting in a coarser texture and intense beefy flavor.
Inside vs. Outside Skirt Steak
There are two types of skirt steak: inside and outside. Outside skirt steak is generally considered more desirable due to its greater tenderness and more uniform thickness. It’s also a bit wider and flatter. Inside skirt steak, on the other hand, is thinner, tougher, and has a membrane that should be removed before cooking. It is also more readily available and often more affordable.
Characteristics of Skirt Steak
Skirt steak is characterized by its thinness, typically no more than ½ inch thick. It has a distinct grain that runs lengthwise. This grain is crucial to consider when slicing the cooked steak, as cutting against the grain is essential for maximizing tenderness. The intense beefy flavor is what makes skirt steak so popular for dishes like fajitas and carne asada.
Best Cooking Methods for Skirt Steak
Skirt steak benefits from quick, high-heat cooking methods. This includes grilling, pan-searing, or broiling. The goal is to achieve a nice sear on the outside while keeping the inside medium-rare to medium. Overcooking skirt steak results in a tough and chewy texture. Marinating skirt steak before cooking is highly recommended, as it helps to tenderize the meat and infuse it with flavor. Marinades with acidic ingredients like lime juice or vinegar are particularly effective.
Exploring Flap Steak
Flap steak, also known as sirloin tip steak or bavette, is a cut of beef taken from the bottom sirloin, located near the flank. While often confused with skirt steak, flap steak has its own unique characteristics.
Characteristics of Flap Steak
Flap steak is thicker than skirt steak, usually around 1 inch thick. It also has a looser, more open grain structure compared to the tight grain of skirt steak. This open grain allows marinades to penetrate deeply, resulting in a very flavorful and tender final product. The flavor of flap steak is robust and beefy, though slightly less intense than skirt steak.
Why Flap Steak is Gaining Popularity
Flap steak has been steadily gaining popularity in recent years, thanks to its affordability, versatility, and delicious flavor. It’s often seen as a great value cut, offering a similar eating experience to more expensive steaks. Chefs and home cooks alike appreciate its ability to take on marinades and its suitability for various cooking methods.
Best Cooking Methods for Flap Steak
Like skirt steak, flap steak benefits from high-heat cooking methods. Grilling and pan-searing are excellent choices. However, due to its thickness, flap steak can also be cooked using reverse searing. This involves cooking the steak at a low temperature until it reaches the desired internal temperature, then searing it over high heat for a beautiful crust. Marinades are also highly recommended for flap steak. Due to its looser grain, flap steak can be cooked to medium or even medium-well without becoming too tough, although medium-rare is still preferred by many.

Marinating for Success
Regardless of whether you choose skirt steak or flap steak, marinating is key to achieving optimal flavor and tenderness. Marinades typically include a combination of oil, acid (like citrus juice or vinegar), and seasonings.
Essential Marinade Ingredients
- Oil: Helps to distribute the flavors and create a protective barrier during cooking.
- Acid: Tenderizes the meat by breaking down muscle fibers.
- Seasonings: Add depth and complexity to the flavor.
Marinating Time
- Skirt steak and flap steak benefit from at least 30 minutes of marinating.
- For deeper flavor, marinate for several hours or overnight in the refrigerator.
Slicing Against the Grain
One of the most important tips for maximizing the tenderness of both skirt steak and flap steak is to slice them against the grain after cooking.
Why Slice Against the Grain?
Slicing against the grain shortens the muscle fibers, making the meat easier to chew. If you slice with the grain, the long muscle fibers remain intact, resulting in a tougher eating experience.
Identifying the Grain
- The grain of skirt steak runs lengthwise along the steak.
- The grain of flap steak is more open and visible.

What exactly are skirt steak and flap steak, and where do they come from on the cow?
Skirt steak and flap steak are both flavorful cuts of beef known for their affordability and versatility. Skirt steak comes from the diaphragm muscle of the cow, specifically the plate section, and is available as inside or outside skirt steak. Flap steak, also known as sirloin tip, comes from the bottom sirloin, located near the flank.
Because of their location and muscle structure, both cuts have distinct textures and flavors. Skirt steak tends to be thinner and wider with a looser grain, making it ideal for quick cooking methods. Flap steak, on the other hand, is typically thicker and has a more pronounced grain, offering a slightly chewier texture but still packed with robust beefy flavor.
How do the flavors of skirt steak and flap steak compare?
Both skirt steak and flap steak boast a rich, beefy flavor, but subtle differences exist. Skirt steak is known for its intensely savory flavor, often described as almost mineral-like, due to its close proximity to the internal organs and the hard work the diaphragm muscle performs. This robust taste makes it a favorite for dishes with bold seasonings.
Flap steak provides a more straightforward beef flavor, less intense than skirt steak but still very satisfying. The more uniform muscle structure allows for even marinating, and it absorbs flavors beautifully, making it suitable for a variety of cuisines and marinades. Its less intense beefiness also makes it approachable for those who might find skirt steak too strong.
What cooking methods are best suited for skirt steak versus flap steak?
Skirt steak excels when cooked quickly over high heat, such as grilling, pan-searing, or broiling. This method allows the thin cut to develop a flavorful crust while remaining tender on the inside. Due to its thinner profile, it’s crucial not to overcook skirt steak, as it can become tough and dry.
Flap steak, thanks to its slightly thicker cut, is more forgiving and versatile in cooking. While it also benefits from high-heat cooking methods like grilling or pan-searing, it can also be cooked using slower methods like sous vide followed by a quick sear. This allows for maximum tenderness and even cooking throughout.
How do the textures of cooked skirt steak and flap steak differ, and how can I ensure tenderness?
Cooked skirt steak has a relatively loose, somewhat stringy texture. Properly cooked, it should be tender and easily cut against the grain. Overcooking will result in a tough, chewy piece of meat. Always slice skirt steak thinly against the grain to maximize tenderness.
Flap steak, while still possessing a distinct grain, has a slightly denser and more substantial texture. To ensure tenderness, it is equally important to slice it against the grain after cooking. Marinating flap steak before cooking can also help break down the muscle fibers, resulting in a more tender and enjoyable bite.
Are skirt steak and flap steak interchangeable in recipes?
While both skirt steak and flap steak can be used in similar recipes, they are not perfectly interchangeable due to their differences in flavor and texture. Recipes that call for a very quick sear and strong flavor profile might be better suited for skirt steak. Dishes requiring a longer marinating time and a less intensely beefy taste might be better suited for flap steak.
Consider the desired outcome of your dish when deciding between the two cuts. If you want an intensely flavorful and slightly chewy steak for tacos or fajitas, skirt steak is an excellent choice. If you prefer a more mellow flavor and a slightly more tender texture for stir-fries or steak salads, flap steak is a good alternative.
Are there nutritional differences between skirt steak and flap steak?
Nutritionally, skirt steak and flap steak are very similar. Both cuts are good sources of protein, iron, and zinc. The fat content can vary slightly depending on the grade and trimming of the meat, but generally, they both contain a moderate amount of fat.
A slight edge may be given to flap steak with a generally lower overall fat percentage in comparison to skirt steak, depending on the cut and source. But this difference tends to be minimal and is unlikely to impact your nutrition significantly. Both are good choices for a protein-rich component to your meal.
How do the prices of skirt steak and flap steak typically compare?
Generally, skirt steak tends to be slightly more expensive than flap steak. This price difference can be attributed to factors such as demand, the amount of yield per animal, and the specific market. However, both cuts are considered relatively budget-friendly options compared to premium steaks like ribeye or tenderloin.
Price fluctuations can occur based on location, butcher shop, and current market trends. Checking prices at your local butcher or grocery store is the best way to determine the current cost of each cut in your area. Ultimately, both skirt steak and flap steak offer excellent value for their flavor and versatility.
