4. Heat 1 tablespoon oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then sauté meat, turning over once, 6 to 8 minutes total for rare (depending on thickness of steak).
5. Transfer to a baking pan and keep warm in oven while making ragout.
6. Heat remaining 2 tablespoons oil in uncleaned skillet over moderately high heat until hot but not smoking, then sauté garlic, rosemary, and red-pepper flakes, stirring, until fragrant, about 30 seconds.
7. Add mushrooms and remaining salt mixture and sauté, stirring frequently and scraping up any brown bits, until mushrooms are tender but still juicy, 6 to 7 minutes.
