Steak cooking is fundamentally a heat transfer process: thermal energy from your cooking surface travels through the meat, denaturing proteins and rendering fat, which creates flavor and texture. The goal is to bring the interior to the target temperature for doneness while developing a brown, flavorful crust through the Maillard reaction on the surface. However, cooking doesn’t stop when you remove the steak from heat — this "carryover cooking" is critical. The hot, cooked outer layers continue transferring heat to the cooler center for 5–10 minutes after removal. A steak pulled at 130°F will rise to 135°F during rest; pull it at 125°F and it reaches your target of 130°F-rare after resting. Ignoring carryover is the most common cause of overcooked steak. Thickness matters enormously: a thin 1/2-inch steak cooks in 2–3 minutes per side and has minimal carryover (maybe 2°F rise), while a 2-inch thick cut takes 8–10 minutes per side and gains 5°F+ during rest.

Different cuts have different optimal cooking methods due to their fat content and muscle structure. Ribeye, rich in fat and marbling, thrives with high-heat pan-searing; the fat renders and bastes the meat during cooking. Filet mignon, the leanest cut, benefits from lower heat to prevent overdrying. Strip steak, a middle ground, performs beautifully either way. The thermostat approach — targeting specific internal temperatures — is far superior to timing alone because heat distribution depends on steak shape, starting temperature, altitude, and your equipment. Always allow steaks to rest at room temperature for 30–60 minutes before cooking; cold meat cooks unevenly, with the outside overdone before the center warms through. After cooking and resting, resist cutting immediately; let the juices redistribute for 5 minutes if you must rest at the table, or 10–15 minutes if serving later.
