How to Cook Skirt Steak
1 pound skirt steak
1 teaspoon kosher salt, as needed for seasoning
1/2 teaspoon ground black pepper, as needed for seasoning
2 tablespoons olive oil
If the skirt steak comes in a long strip, cut into 2 or 3 smaller pieces, 5 to 7 inches in length. This will allow them to fit better in the pan, and make them easier to slice later.
Thoroughly pat steaks dry with paper towels on each side. The surface should be very dry to help brown the surface of the meat. Generously season each side of the steaks with salt and pepper.
Heat a large 12-inch cast iron skillet over high heat for 3 minutes. Once hot, add the olive oil.
Use tongs to carefully add the steak to the pan, then press down firmly on the surface a few times for more contact. Sear the first side until browned, about 2 to 4 minutes, depending on the thickness of the meat. Flip and cook another 2 to 4 minutes. For medium rare doneness, cook steak until it reaches an internal temperature of 130ºF. Work in two batches if needed.
Transfer steak to a cutting board, loosely cover with foil, and allow to rest for 10 minutes before slicing.
Hold the carving knife at a 45-degree angle, and then slice the steak across the grain, about 1/4-inch thick slices. Transfer skirt steak to a serving plate.
