Inside skirt steak, also known as the diaphragm muscle of the cow, is a flavorful cut of beef prized for its rich taste and affordability. However, it can be notoriously tough if not prepared properly. The key to unlocking its delicious potential lies in understanding its muscle structure and applying techniques that break down those tough fibers. This guide will provide you with a complete understanding of how to transform an inside skirt steak into a tender and mouthwatering meal.
Understanding Inside Skirt Steak
Before diving into tenderizing methods, it’s crucial to understand the unique characteristics of inside skirt steak. This cut comes from the plate section of the cow, specifically the diaphragm muscle, which is responsible for breathing. This muscle works hard, resulting in long, tightly packed muscle fibers.
Its grain runs lengthwise, making it easy to slice against for maximum tenderness after cooking. This is a critical point to remember. Unlike other cuts where you might trim against the grain before cooking, with skirt steak, you cook it whole and slice accordingly.
Inside skirt steak has a looser membrane covering and is generally wider and thinner compared to outside skirt steak. The flavor is robust and beefy, making it ideal for grilling, pan-searing, and marinating.
Tenderizing Techniques: Breaking Down the Muscle Fibers
Several techniques can be employed to tenderize inside skirt steak. These methods fall into three primary categories: physical tenderization, chemical tenderization, and cooking methods. Often, a combination of these approaches yields the best results.
Physical Tenderization: Hammering Away Toughness
Physical tenderization involves using force to break down the muscle fibers. This can be achieved through several methods.
Using a Meat Mallet
The most common and effective method of physical tenderization is using a meat mallet or tenderizing hammer. Place the skirt steak between two sheets of plastic wrap or in a resealable plastic bag to prevent splattering and protect the meat. Use the flat side of the mallet to pound the steak evenly, applying firm but controlled pressure. Avoid using excessive force, as this can pulverize the meat and make it mushy.
The goal is to flatten the steak slightly and disrupt the muscle fibers without completely destroying its texture. Aim for a consistent thickness throughout the steak.
Needling or Jaccarding
A needling device or jaccard is another physical tenderizing tool that creates small perforations in the meat. These tiny holes sever the muscle fibers, making the steak more tender. This method is less likely to alter the overall shape and thickness of the steak compared to using a meat mallet.
Simply press the jaccard firmly and evenly across the surface of the steak, ensuring that the entire cut is treated.
Chemical Tenderization: Marinades and More
Chemical tenderization involves using acidic or enzymatic ingredients to break down the proteins in the meat.
The Power of Marinades
Marinades are a popular and effective way to tenderize and flavor inside skirt steak. Acidic ingredients like citrus juice (lemon, lime, orange), vinegar (balsamic, red wine), and yogurt help to denature the proteins, making the steak more tender.
Enzymatic ingredients, such as pineapple juice (containing bromelain), papaya (containing papain), and ginger (containing zingibain), also work to break down the muscle fibers. Be cautious when using enzymatic marinades, as they can quickly over-tenderize the meat, resulting in a mushy texture. Limit the marinating time to a few hours.
A good marinade should also include oil to help distribute the flavors and prevent the steak from drying out, as well as herbs and spices to enhance the overall taste.
Here’s a sample marinade recipe:
- 1/4 cup olive oil
- 1/4 cup lime juice
- 2 cloves garlic, minced
- 1 tablespoon soy sauce
- 1 teaspoon chili powder
- 1/2 teaspoon cumin
- Salt and pepper to taste
Combine all ingredients in a resealable plastic bag or shallow dish. Add the skirt steak, ensuring it is fully coated in the marinade. Marinate in the refrigerator for at least 30 minutes, or up to 4 hours.
Dry Rubs and Tenderizing Agents
While marinades are the most common form of chemical tenderization, dry rubs can also contribute to tenderness. Ingredients like salt can draw out moisture from the meat, which helps to break down proteins. Some commercial dry rubs also contain enzymatic tenderizers.
Apply the dry rub generously to the skirt steak at least 30 minutes before cooking. For even better results, apply the rub the night before and let it sit in the refrigerator.
Cooking Methods: Achieving the Perfect Doneness
The cooking method plays a crucial role in the final tenderness of inside skirt steak. High-heat cooking methods, such as grilling and pan-searing, are ideal for this cut.
Grilling for Maximum Flavor
Grilling is a popular method for cooking inside skirt steak because it imparts a smoky flavor and creates a nice sear. Preheat your grill to high heat. Make sure the grates are clean and lightly oiled to prevent sticking.
Place the skirt steak on the hot grill and cook for 2-3 minutes per side for medium-rare, or slightly longer for medium. Avoid overcooking, as this will make the steak tough and dry.
Use a meat thermometer to check the internal temperature. For medium-rare, aim for 130-135°F (54-57°C). For medium, aim for 135-145°F (57-63°C).
Pan-Searing for a Crispy Crust
Pan-searing is another excellent option for cooking inside skirt steak. Use a heavy-bottomed skillet, preferably cast iron, and heat it over high heat. Add a tablespoon or two of high-smoke-point oil, such as canola or grapeseed oil.
Once the oil is shimmering hot, carefully place the skirt steak in the skillet. Sear for 2-3 minutes per side, or until a rich, brown crust forms. As with grilling, avoid overcooking. Use a meat thermometer to ensure the steak is cooked to your desired doneness.
Reverse Searing: A Tender and Flavorful Approach
Reverse searing involves cooking the steak at a low temperature for a longer period, followed by a quick sear at high heat. This method promotes even cooking and results in a tender and juicy steak.
Preheat your oven to 250°F (120°C). Place the skirt steak on a baking sheet lined with a wire rack. Cook for 20-30 minutes, or until the internal temperature reaches 120-125°F (49-52°C).
Remove the steak from the oven and let it rest for a few minutes. Then, heat a skillet over high heat and add a tablespoon or two of oil. Sear the steak for 1-2 minutes per side, until a rich, brown crust forms.
The Importance of Slicing Against the Grain
Regardless of the cooking method you choose, slicing the inside skirt steak against the grain is essential for maximizing tenderness. As mentioned earlier, the grain of skirt steak runs lengthwise. To slice against the grain, cut perpendicular to the direction of the muscle fibers.
This shortens the fibers, making the steak much easier to chew. Use a sharp knife to slice the steak thinly on a bias.
Tips for Success: From Purchase to Plate
-
Choose quality meat: Look for inside skirt steak that is bright red in color and has a good amount of marbling (intramuscular fat).
-
Don’t overcrowd the pan or grill: Cook the steak in batches if necessary to ensure proper searing. Overcrowding lowers the temperature and can result in steaming instead of searing.
-
Let the steak rest: After cooking, let the steak rest for 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
-
Season generously: Skirt steak can handle bold flavors. Don’t be afraid to season it generously with salt, pepper, and your favorite herbs and spices.
-
Experiment with different marinades: Try different combinations of acidic and enzymatic ingredients to find your favorite marinade.
-
Consider using a sous vide: Sous vide cooking can precisely control the internal temperature of the steak, guaranteeing a tender and evenly cooked result.
Serving Suggestions: Completing the Meal
Inside skirt steak is incredibly versatile and can be used in a variety of dishes. It’s a classic choice for fajitas, tacos, and steak salads. It also pairs well with grilled vegetables, mashed potatoes, and rice.
Consider serving it with a flavorful sauce, such as chimichurri, salsa verde, or a simple pan sauce made with butter, garlic, and herbs.

By understanding the characteristics of the cut, employing appropriate tenderizing methods (physical or chemical), cooking it properly, and slicing it against the grain, you can transform this flavorful cut into a delicious and satisfying meal. Don’t be afraid to experiment with different marinades, cooking methods, and serving suggestions to find your perfect skirt steak recipe. With practice, you’ll be able to consistently produce tender and mouthwatering inside skirt steak that everyone will enjoy.
What exactly is inside skirt steak and why is it sometimes tough?
Inside skirt steak is a thin, flavorful cut of beef from the plate primal cut, specifically from the diaphragm muscle. It’s located inside the chest cavity, closer to the flank. This cut is known for its intense beefy flavor, but it can be quite tough if not prepared correctly.
The toughness stems from the tightly packed muscle fibers that run lengthwise through the steak. These fibers are relatively coarse and can become chewy when cooked improperly. Additionally, the thinness of the cut means it can easily overcook, further exacerbating the toughness issue.
What are the key steps to tenderizing inside skirt steak before cooking?
The primary steps to tenderizing inside skirt steak involve breaking down those tough muscle fibers. This can be achieved through physical methods like pounding with a meat mallet, scoring the surface to cut through the fibers, or using a Jaccard meat tenderizer (needle tenderizer). These methods disrupt the muscle structure, leading to a more tender final product.
Another important step is marinating the skirt steak. Marinades typically include acidic ingredients like vinegar, citrus juice, or yogurt, which help to denature the proteins and tenderize the meat. Combining these acidic elements with flavorful herbs, spices, and oil not only tenderizes the steak but also infuses it with delicious flavor.
How does marinating affect the tenderness and flavor of inside skirt steak?
Marinating significantly enhances both the tenderness and flavor of inside skirt steak. The acidic components in the marinade, such as lemon juice or vinegar, work to break down the tough muscle fibers, making the meat more palatable. Enzymes in some marinades, like those containing pineapple juice, further aid in this process.
Beyond tenderizing, a well-composed marinade infuses the steak with layers of flavor. The oil helps to carry the flavors throughout the meat, while the herbs and spices contribute their unique aromatic profiles. The result is a more tender and flavorful steak compared to cooking it without any prior marination.
What are some recommended marinades for inside skirt steak?
Numerous marinade recipes work well with inside skirt steak, each offering a unique flavor profile. A classic fajita marinade often includes lime juice, soy sauce, garlic, cumin, and chili powder, delivering a zesty and savory kick.
