Briefly cooking the gravy with thyme sprigs saves the time of stripping the tiny leaves from the stem, but still gives you the herb's woodsy flavor in this steak recipe. Serve over pasta, as instructed.
The combination of cumin, coriander, and ground red pepper create a tasty rub for the beef. Brown sugar aids caramelization. Heating the cast-iron skillet results in a flavorful seared crust on the steak without having to first brown the meat on the stovetop.
