1. Coat steaks with spray, then season with pepper (wash hands). Preheat large, nonstick sauté pan on medium-high 2–3 minutes. Place steaks in pan; sear 2–3 minutes on each side, or until browned. Remove steaks from pan; reduce heat to medium. Lightly smash garlic cloves.
2. Add butter, rosemary, and garlic to pan; cook 1 minute. Move rosemary and garlic to edge of pan; return steaks to pan; cook 3–5 minutes on each side and until 125°F (for medium rare; warm red center), 130°F (for medium; warm pink center), or up to 170°F (for well done), basting steaks with butter mixture by brushing tops with rosemary sprigs. Remove steaks from pan and let stand 5 minutes before serving; temperature will rise 5–10°F during this time. Brush steaks with remaining butter mixture from pan and sprinkle with salt; serve.

NOTE: The doneness temperatures for medium rare and medium stated above are traditional temperatures used for cooking steaks, but are not recommended by the USDA. To maintain food safety, the USDA recommends an internal temperature of 145°F, as measured using a food thermometer, with a 3-minute rest time before carving.
