Beef Skirt Steak

Introduction to Beef Skirt Steak

There are actually two types of Skirt Steak: the inside skirt and the outside skirt. The outside skirt is the more desirable of the two. It’s thicker, more tender, and more evenly shaped. It’s also often covered by a tough membrane that needs to be removed before cooking. The inside skirt is thinner, wider, and generally tougher, with more connective tissue. While both have great flavor, the outside skirt is preferred for its better texture. When buying “Skirt Steak” without a specific designation, it’s often the inside skirt, so be sure to ask your butcher if you’re looking for the outside skirt.

Culinary History of Beef Skirt Steak

Skirt Steak’s culinary history is closely tied to Tex-Mex and Mexican cuisine, particularly its use in fajitas. The dish, which features grilled, sliced steak served with tortillas and various toppings, is believed to have originated in the ranch lands of South and West Texas in the 1930s. Ranch workers were often given less desirable cuts of beef, including the skirt steak, as part of their pay. They developed ways to tenderize and flavor the meat, leading to the creation of fajitas. The dish gained widespread popularity in the late 20th century, solidifying Skirt Steak’s place in culinary history.

Early Days: The Diaphragm Muscle and its Challenges

The skirt steak is the diaphragm muscle of the cow. There are two main types:

• Outside Skirt: This is the diaphragm muscle proper, attached to the 6th through 12th ribs on the outside of the chest wall. It’s generally wider and thicker than the inside skirt. It is often covered in a tough membrane that must be removed before cooking.
• Inside Skirt: Located inside the chest cavity, this is technically the transversus abdominis muscle. It’s typically thinner, narrower, and more readily available in supermarkets.

In the early days of beef consumption, the skirt steak faced several challenges:

• “Offal” Status: Historically, the diaphragm was often considered “offal” – a category of organ meats and less desirable cuts that were not always highly valued in Western cuisines.
• Toughness: The skirt steak is a heavily worked muscle, resulting in a naturally tough texture if not prepared correctly.
• Membrane Removal: The outside skirt, in particular, requires meticulous trimming to remove the thick, tough membrane that covers it. This added to the labor involved in preparing the cut.
• Limited Shelf Life: Like other offal cuts, the skirt steak had a shorter shelf life than muscle meats, making it less appealing for commercial distribution.

These factors led to its early uses:

• Ground Beef: Much of the skirt steak was simply ground into hamburger, where its toughness was less of an issue.
• Butcher’s Choice/Employee Meat: Butchers, aware of the cut’s intense flavor, often kept it for themselves or their families, or sold it at a lower price to employees and savvy customers.
• Regional and Ethnic Cuisines: In some cultures, particularly in Latin America, the skirt steak (or similar cuts) found its way into traditional dishes, often utilizing marinating and slow cooking techniques to tenderize the meat.

The Tex-Mex Transformation: Fajitas and the Rise of Skirt Steak

The turning point in the skirt steak’s culinary history came with the rise in popularity of Tex-Mex cuisine, particularly the dish known as fajitas. While the exact origins of fajitas are debated, the generally accepted story places their roots in the Rio Grande Valley of South Texas in the 1930s and 40s.

• Vaquero Traditions: Mexican ranch workers (vaqueros) in Texas were often given less desirable cuts of beef, including the skirt steak, as part of their payment. They developed ways to cook this tough but flavorful meat over campfires, grilling it and serving it with tortillas, onions, and peppers. The term “faja” is Spanish for “belt,” “strip,” or “girdle,” referring to the shape of the skirt steak.
• Early Fajita Popularity: These early fajitas were primarily a regional, working-class food, not widely known outside of South Texas.
• Commercialization in the 1970s and 80s: The 1970s and 80s saw the commercialization and popularization of fajitas. Restaurants, particularly in Texas, began featuring fajitas on their menus, often with a theatrical presentation involving sizzling platters and a build-your-own approach.
  • Sonny Falcon: Is often given credit to popularizing the term and dish in restaurants.
  • Ninfa Laurenzo: Also heavily credited, of “Ninfa’s” in Houston.
• Skirt Steak’s Star Turn: Skirt steak became the cut associated with fajitas, its intense beefy flavor and ability to hold up to high-heat grilling making it ideal for the dish. The “fajita craze” of the 1980s propelled skirt steak from obscurity to mainstream popularity.
• Price Increase: As demand for skirt steak skyrocketed, its price increased dramatically, transforming it from a budget-friendly cut to a more premium option.

Beyond Fajitas: Expanding Culinary Horizons

While fajitas were the primary driver of skirt steak’s popularity, chefs and home cooks began to explore its versatility in other culinary applications:

• Carne Asada: This Mexican grilled meat dish, traditionally made with various cuts, increasingly utilized skirt steak for its flavor and texture.
• Steak Sandwiches: Thinly sliced, grilled skirt steak became a popular filling for steak sandwiches.
• Salads: Grilled skirt steak added a flavorful and protein-rich element to salads.
• Asian-Inspired Dishes: Skirt steak’s ability to absorb marinades and its suitability for quick cooking made it a natural fit for stir-fries and other Asian-inspired preparations.
• French cooking. In France onglet is a similarly shaped and textured cut from near the diaphragm.

Skirt Steak Today: A Culinary Staple

Today, skirt steak is a widely recognized and appreciated cut, readily available in most supermarkets and butcher shops. It’s no longer considered “offal” but a premium cut, prized for its:

• Intense Flavor: Its robust, beefy flavor is its most defining characteristic.
• Grilling Prowess: It excels on the grill, developing a flavorful crust while remaining tender (when cooked to medium-rare or medium).
• Versatility: It can be used in a wide range of dishes, from Tex-Mex classics to Asian stir-fries to elegant steak salads.
• Marinating Affinity: It absorbs marinades exceptionally well, allowing for endless flavor variations.

Key Considerations

• Inside vs. Outside Skirt: While both are flavorful, the outside skirt is generally considered more desirable due to its thicker, wider shape and more intense flavor. However, it requires more careful trimming.
• Cooking to Medium-Rare: Skirt steak is best cooked to medium-rare or medium to maintain tenderness. Overcooking will result in a tough, chewy texture.
• Slicing Against the Grain: This is crucial for maximizing tenderness. Skirt steak has very distinct muscle fibers, and slicing against the grain shortens those fibers, making the meat easier to chew.

The culinary history of the skirt steak is a remarkable story of transformation. From an overlooked and undervalued cut to a culinary star, its journey reflects the power of regional culinary traditions, the influence of popular cuisine, and the growing appreciation for flavor and versatility in the world of beef. It’s a reminder that culinary excellence can be found in unexpected places, and that even the most humble cuts of meat can have a rich and flavorful history.

Understanding the Cut: Location and Characteristics

Skirt steak comes from the diaphragm muscle of the cow, located in the plate primal, which is below the rib primal. There are actually two types of skirt steak:

• Outside Skirt Steak: This is the more commonly available and generally preferred type. It’s longer, wider, and slightly thicker than the inside skirt. It also tends to be more tender. It’s covered in a tough membrane that must be removed before cooking.
• Inside Skirt Steak: This is narrower, thinner, and generally tougher than the outside skirt. It also has a membrane that should be removed.

Both types of skirt steak have a very pronounced grain (muscle fibers running in a parallel direction) and a relatively loose, open texture. This texture allows them to absorb marinades exceptionally well. The intense flavor comes from the muscle’s hard work and its location near internal organs.

Nutritional Breakdown: Flavorful and Moderately Lean

Skirt steak is known for its flavor, and while it’s not the absolute leanest cut, it’s leaner than many other flavorful options like ribeye. Here’s a detailed look at the typical nutritional content of a 3.5-ounce (100-gram) serving of cooked skirt steak (values can vary based on the specific grade of beef, whether it’s outside or inside skirt, and the cooking method):

• Calories: Approximately 180-220 calories.
• Protein: 24-29 grams. An excellent source of complete protein.
• Fat: 8-13 grams. Falls into the moderately lean category.
• Saturated Fat: 3-5 grams. The saturated fat content is moderate.
• Cholesterol: 65-85 milligrams. Comparable to other cuts of beef.
• Iron: 2-3 milligrams. Provides heme iron, which is easily absorbed.
• Zinc: 4-6 milligrams. A good source of zinc, important for immune function.
• Selenium: 20-30 micrograms. Offers antioxidant benefits.
• Vitamin B12: 2-3 micrograms. An excellent source of this essential vitamin.
• Niacin (Vitamin B3): 5-7 milligrams. Contributes to energy metabolism.
• Vitamin B6 (Pyridoxine): 0.4-0.6 milligrams. Important for various bodily functions.
• Phosphorus: 150-200 milligrams. Supports bone health.

Key Nutritional Advantages

• High in Protein: Skirt steak is a protein powerhouse, essential for building and repairing tissues.
• Moderately Lean: Offers a good balance of flavor and leanness, making it a healthier choice than many fattier cuts.
• Rich in Essential Nutrients: Provides significant amounts of iron, zinc, selenium, and B vitamins.
• Intense Flavor: Known for its robust, beefy flavor, which is more pronounced than in many leaner cuts.

The Importance of Proper Cooking and Slicing

Skirt steak’s texture and grain require specific cooking and slicing techniques to maximize tenderness:

• High Heat, Quick Cooking: Skirt steak is best cooked quickly over high heat (grilling, broiling, or pan-searing) to medium-rare or medium doneness. Overcooking will make it extremely tough and chewy.
• Marinating (Highly Recommended): Marinating is almost essential for skirt steak, especially the inside skirt. The marinade not only adds flavor but also helps to tenderize the meat. Acidic marinades are particularly effective.
• Slicing Against the Grain: This is absolutely crucial for tenderness. After cooking and resting, slice the steak thinly and against the grain (perpendicular to the muscle fibers). This shortens the fibers, making it much easier to chew. The grain on skirt steak is very easy to see.

Healthy Cooking Methods

• Grilling: A classic and excellent way to cook skirt steak, imparting a smoky char.
• Broiling: Similar to grilling, provides high, direct heat.
• Pan-Searing: A quick and convenient method for cooking on the stovetop.
• Stir-Frying (thinly sliced): Thinly sliced skirt steak is perfect for stir-fries.

Incorporating Skirt Steak into a Balanced Diet

• Pair with Vegetables: Combine with vegetables.
• Choose Whole Grains: Opt for whole-grain sides.
• Portion Control: A 3-4 ounce serving is a good guideline.
• Dietary Variety: Include a variety of protein sources.

Skirt Steak vs. Other Cuts

• Vs. Flank Steak: Skirt steak and flank steak are often used interchangeably, but they have subtle differences. Skirt steak generally has a more intense flavor and a slightly looser texture. Skirt steak also tends to have a bit more fat.
• Vs. Ribeye: Skirt steak is significantly leaner than ribeye, which is a much fattier cut.
• Vs. Filet Mignon: Skirt steak has a much more robust flavor and a chewier texture than filet mignon, which is prized for its tenderness. Skirt is also much less expensive.
• Vs Sirloin Flap: Skirt tends to cook faster and can handle more heat.
