Method
- Whisk the olive oil, soy sauce, vinegar, Worcestershire, mustard, brown sugar, garlic, pepper and thyme together.
- Lay the steaks between two sheets of plastic wrap and pound the thicker parts to an even ¾ inch (2 cm).
- Put the steaks and marinade in a zip-top bag, press out the air and refrigerate 2 to 12 hours, turning once.
- Take the steaks out 20 to 30 minutes before cooking. Lift them from the marinade, discard the marinade and pat the steaks very dry.
- Heat the skillet over medium-high heat for 3 to 4 minutes, add the neutral oil and heat until it shimmers.
- Sear 2 steaks at a time without moving for about 3 minutes, until deeply browned. Flip and cook 2 to 3 minutes more, adding the butter for the last minute and spooning it over. Lower the heat a notch if the sugar in the marinade starts to burn.
- Check the thickest part: pull at 130°F (54°C) for medium-rare or 135°F (57°C) for medium, or cook to 145°F (63°C) for the USDA guidance, about 3½ to 4 minutes per side for ¾-inch steaks.
- Rest the steaks on a board for 5 minutes (at least 3). Slice ¼ inch (6 mm) thick against the grain, spoon the pan juices over and finish with flaky salt.
Notes
Times are for ¾-inch steaks; see the time chart in the post for other thicknesses. USDA guidance for whole beef cuts is 145°F (63°C) with a 3-minute rest; medium-rare and medium are below it, and mechanically tenderized steaks should always reach 145°F. Don't marinate longer than 24 hours. Refrigerate leftovers within 2 hours and eat within 3 to 4 days. Calories are an estimate per serving from USDA FoodData Central values, counting all of the searing oil and butter and about half of the marinade.
