Grilled Skirt Steak Recipe
- Prep Time: 15 minutes (plus 2-12 hours marinating)
- Cook Time: 6-10 minutes
- Yield: 4 servings
Ingredients
- 1.5 – 2 pounds skirt steak (inside or outside)
- 2 tablespoons olive oil
- 1/4 cup soy sauce or tamari
- 2 tablespoons red wine vinegar or lime juice
- 1 tablespoon Worcestershire sauce
- 2 cloves garlic, minced
- 1 teaspoon smoked paprika
- 1/2 teaspoon black pepper, freshly ground
- 1/4 teaspoon red pepper flakes (optional)
- Kosher salt, to taste (for post-grill seasoning)
Instructions
- Trim the Steak: Remove any thick silver skin or excess hard fat from the skirt steak using a sharp knife. Pat the steak thoroughly dry with paper towels.
- Prepare the Marinade: In a shallow dish or a resealable bag, combine olive oil, soy sauce, red wine vinegar, Worcestershire sauce, minced garlic, smoked paprika, and black pepper. Add red pepper flakes if using.
- Marinate the Steak: Place the trimmed skirt steak into the marinade, ensuring it is fully coated. Seal the bag or cover the dish and refrigerate for a minimum of 2 hours, and up to 12 hours. For thinner cuts, 2-4 hours is sufficient.
- Preheat the Grill: Set up your grill for two-zone cooking. Preheat one side to high heat (450-550°F / 230-290°C) and the other side to medium-low heat. Clean the grill grates thoroughly with a wire brush.
- Grill the Steak: Remove the steak from the marinade, allowing any excess to drip off. Place the skirt steak directly over the high heat zone. Sear for 2-4 minutes per side, turning once, until a deep brown crust forms.
- Check Doneness: For medium-rare (130-135°F / 54-57°C), cook for approximately 6-8 minutes total. For medium (135-140°F / 57-60°C), cook for 8-10 minutes total. Use an instant-read meat thermometer inserted into the thickest part of the steak.
- Rest the Steak: Transfer the grilled skirt steak to a cutting board. Tent it loosely with foil and allow it to rest for 5-10 minutes. This resting period allows the juices to redistribute throughout the meat.
- Slice and Serve: Locate the grain of the meat. Using a sharp knife, slice the steak very thinly against the grain at a slight angle. Season with kosher salt to taste. Serve immediately.
Understanding Skirt Steak: Your Guide to a Flavorful Cut
Skirt steak comes from the diaphragm muscle of the cow, offering a robust, beefy flavor that stands out among other cuts. There are two primary types: inside skirt and outside skirt. The outside skirt is generally thicker, wider, and more uniform in shape, often preferred for its tenderness and marbling. The inside skirt is narrower, thinner, and can be tougher if not prepared correctly.
Both types feature long, coarse muscle fibers, known as the grain, which is a defining characteristic of this cut. This prominent grain plays a critical role in how the steak is sliced after cooking, directly impacting its tenderness.
Prepping for Success: Trimming and Seasoning Skirt Steak
Proper preparation before grilling ensures a better texture and flavor. Skirt steak often comes with a tough, silvery membrane called silver skin, which does not render during cooking and should be removed. Use a sharp, flexible knife to carefully separate the silver skin from the meat, pulling it away as you slice.
Excess hard fat can also be trimmed, though a thin layer of fat contributes to flavor and juiciness. Patting the steak thoroughly dry with paper towels before seasoning or marinating is essential; moisture on the surface hinders the development of a flavorful crust during searing.
Some cooks opt to score the steak lightly across the grain on both sides before marinating. This practice can help tenderize the meat and allow marinades to penetrate deeper, though it is not strictly necessary for a good result.
Mastering Marinades for Skirt Steak: Infusing Deep Flavor
Marinating skirt steak is a widely adopted practice that enhances its flavor and can contribute to tenderness. Marinades typically combine an acid, an oil, and various aromatics and seasonings. The acid, such as citrus juice or vinegar, helps to break down muscle fibers on the surface, while the oil helps distribute fat-soluble flavors and prevents the meat from drying out.
Common marinade ingredients include soy sauce, Worcestershire sauce, garlic, onion, herbs like oregano or cilantro, and spices such as cumin or chili powder. Marinating times for skirt steak generally range from a minimum of 2 hours to a maximum of 12 hours. Over-marinating with highly acidic ingredients can result in a mushy texture, so adherence to recommended times is beneficial.
| Flavor Profile | Acid Component | Aromatic/Spice |
|---|---|---|
| Classic Steakhouse | Red Wine Vinegar | Garlic, Black Pepper, Rosemary |
| Southwestern | Lime Juice | Cumin, Chili Powder, Cilantro |
| Asian-Inspired | Soy Sauce (acidic elements) | Ginger, Garlic, Sesame Oil |
How To Grill a Skirt Steak: Achieving Optimal Tenderness and Taste
Grilling skirt steak requires high heat to achieve a beautiful sear and a quick cook time to prevent toughness. Set up your grill for two-zone cooking, establishing one side with high, direct heat (450-550°F / 230-290°C) and the other with medium-low, indirect heat. This setup allows for searing and then moving the steak if it cooks too quickly.
Remove the marinated steak from the refrigerator 30 minutes before grilling to allow it to come closer to room temperature, promoting more even cooking. Pat it dry again if it appears wet from the marinade. Place the steak directly over the high heat zone. Sear each side for 2-4 minutes, turning only once, until a deep brown crust develops.
For a medium-rare doneness, target an internal temperature of 130-135°F (54-57°C). For medium, aim for 135-140°F (57-60°C). The USDA recommends cooking whole cuts of beef to a minimum internal temperature of 145°F (63°C) with a three-minute rest for food safety. An instant-read meat thermometer inserted into the thickest part of the steak is the most reliable way to gauge doneness.
| Doneness Level | Target Internal Temp (°F) | Target Internal Temp (°C) |
|---|---|---|
| Rare | 120-125°F | 49-52°C |
| Medium-Rare | 130-135°F | 54-57°C |
| Medium | 135-140°F | 57-60°C |
| Medium-Well | 140-145°F | 60-63°C |
Grilling Techniques: High Heat and Direct Searing
The key to a perfectly grilled skirt steak lies in the high-heat, direct searing method. This technique rapidly cooks the exterior, creating a flavorful crust through the Maillard reaction, while keeping the interior juicy. Avoid overcooking, as skirt steak can become tough very quickly due to its lean nature and coarse grain.
Once the steak has seared on both sides, if it needs a few more minutes to reach your desired internal temperature without burning the exterior, move it to the cooler, indirect heat zone. This allows for more controlled cooking. Resist the urge to press down on the steak with tongs or a spatula, as this squeezes out valuable juices.
The Crucial Rest and Slice: Maximizing Juiciness
After removing the skirt steak from the grill, transfer it to a clean cutting board and tent it loosely with aluminum foil. Allowing the steak to rest for 5-10 minutes is a non-negotiable step. During grilling, the muscle fibers contract, pushing juices to the center of the meat. Resting allows these juices to redistribute throughout the steak, resulting in a more succulent and tender final product.
Slicing skirt steak correctly is just as important as grilling it. Identify the long muscle fibers, or grain, of the steak. You must slice the steak thinly against the grain, meaning perpendicular to the direction of these fibers. Slicing with the grain will result in long, chewy strands of meat. A slight angle (about 45 degrees) during slicing can further enhance tenderness.
Essential Gear and Grilling Safety Considerations
Having the right tools makes grilling safer and more efficient. A sturdy pair of long-handled tongs provides control when flipping the steak. A reliable instant-read meat thermometer is critical for accurately checking internal temperatures, preventing under or overcooking. A clean, stiff-bristled grill brush helps maintain clean grates, reducing sticking and flare-ups.
Grilling safety involves several key practices. Always ensure your grill is stable and placed on a non-combustible surface, away from anything flammable. Keep a fire extinguisher or a bucket of sand nearby. Prevent cross-contamination by using separate cutting boards and utensils for raw meat and cooked meat or other ingredients. Wash hands thoroughly with soap and water after handling raw meat.
