How to Make It
In a large heavy skillet, heat 1 tablespoon of the oil. When it just begins to smoke, season both sides of the steak generously with salt and pepper and cook over moderately high heat for 3 minutes per side for medium rare. Transfer the steak to a warmed platter.
Add the remaining 1 1/2 tablespoons of oil and the rosemary to the skillet and stir frequently until the rosemary begins to color, about 1 1/2 minutes. Scrape the oil over the steak, garnish with the rosemary sprigs and serve.
