Pat the steak dry and season with salt, pepper & steak seasoning. Place the steak in a zip lock bag or container. Top with olive oil and worcestershire sauce. Place in the refrigerator to marinate for at least 1 hr. or up to overnight for deeper flavors.
Take the steak out of your refrigerator 20 minutes before you are ready to cook, so it can come to room temp. Turn your oven broiler to high. Set your oven rack about 5-6 inches away from the flame. (I don’t like it to be too close to increase the chance of grease splattering up and smoking.)
Prepare your baking sheet by lining it with aluminum foil and a wire baking rack on top. Place your skirt steak on the wire rack. Broil for 7 minutes, carefully flip, and cook for another 7 minutes.
Remove from the oven, tent the steak with foil and let rest for a few minutes before slicing against the grain into thin slices.
