Awesome Steak

1. Preheat oven to 400. Heat oil in a large cast-iron or other ovenproof skillet (not a nonstick) over medium-high until it begins to smoke. 
2. Pat steak dry with paper towels. Season each side with 1 teaspoon coarse salt and 1 teaspoon cracked pepper.
3. Cook steak in skillet over medium-high heat until a dark crust has formed, 5 to 7 minutes per side (reduce heat if meat is browning too quickly). Holding steak with tongs, quickly brown all edges, turning as necessary; lay steak flat in skillet.
4. Transfer skillet to oven. 
5. Roast for about 7-10 minutes for a medium to medium well steak. 
6. Transfer to a plate, cover loosely with aluminum foil, and let rest 5 to 10 minutes (temperature will then rise another 5 to 10 degrees). 
7. Slice across the grain and serve
