Take the skirt steak out of the refrigerator about 30 minutes before cooking to bring it to room temperature. This helps it cook more evenly.
Pat the steak dry with paper towels to remove any excess moisture, which will help with browning.
Season the skirt steak generously with salt and pepper on both sides. You can also add other seasonings like garlic powder, paprika, or your favorite steak seasoning for extra flavor.
Place a large, heavy-bottomed skillet (preferably cast iron) over medium-high heat. Let it preheat for a few minutes until it's hot.
Add a little bit of oil to the hot skillet and swirl it around to coat the bottom.
Carefully place the skirt steak in the pan. You should hear a sizzling sound as soon as it touches the skillet.
Cook the steak for about 3-4 minutes on each side for medium-rare, or adjust the cooking time according to your desired doneness. Skirt steak is thin, so it cooks quickly. If it's a thicker cut, you might need a little longer.
Avoid moving the steak around too much while it's cooking to ensure a good sear.
Use a meat thermometer to check the internal temperature. For medium-rare, it should register around 130-135°F (54-57°C).
Once the steak reaches your desired doneness, transfer it to a cutting board and let it rest for about 5-10 minutes. This allows the juices to redistribute throughout the meat, ensuring a juicy steak.
After resting, slice the skirt steak against the grain into thin strips. This helps to maximize tenderness.
Serve immediately while it's still warm. It pairs well with a variety of sides such as roasted vegetables, mashed potatoes, or a fresh salad.
