Rest time

Rest time is the period after meat comes off the grill, during which it sits, usually loosely tented with foil, before it gets sliced or served. During cooking, muscle fibers tighten and push juice toward the center and surface of the meat. Cutting immediately lets most of that juice run out onto the board, while resting gives the fibers time to relax and reabsorb some of that moisture, so the meat stays noticeably juicier.

Rest time also does food safety work. USDA guidance for whole cuts of beef, pork, veal and lamb sets the safe minimum at 145 degrees Fahrenheit combined with a three minute rest, since that rest period allows carryover heat to finish evening out the temperature through the whole cut, not just the point where the thermometer happened to read.

Larger cuts like brisket or pork shoulder benefit from a much longer rest, often thirty minutes to an hour or more wrapped in a cooler, while a thin steak may only need five minutes. A common mistake is resting meat uncovered in a cold kitchen, which lets it cool too fast, or skipping the rest altogether because the table is waiting, which usually shows up as a dry, watery cutting board instead of a juicy plate.
