As a rough estimate, rest your cooked brisket for a half-hour at a minimum, but ideally 1 hour. The important part is that you’re letting it rest at all. However, for those looking to get scientific about it, here’s the best way to determine how long to let brisket rest…
The length of time depends on your smoker temperature. When smoking at 250 degrees, allow 1 hour of cook time for every 1 pound of brisket. A 2-pound brisket only takes around 2 hours in the smoker.
The general rule of thumb is that every pound of brisket needs one hour at 250 degrees Fahrenheit. Therefore, 15 hours should be enough time for a 15-pound brisket, and a 2-pound brisket would take a couple of hours. But that’s not the whole story…
I’m going to show you how to smoke a brisket on a charcoal grill step by step from start to glorious finish. If you’re using a gas grill, I’ve got you covered, too.
At 225 degrees and 1-1/2 to 2 hours a pound, a 3-pound brisket needs between 4-1/2 and 6 hours to cook. At 250 it would take about 3 hours.
When cooking a brisket at 250 degrees, one pound of meat equals one hour of cook time. By that measure, 10 pounds of brisket takes about 10 hours in the smoker.
When cooking a brisket at 250, the general rule of thumb is that 1 pound of meat equals 1 hour of cook time. More precisely, smoke until the internal temperature of the meat reaches 190 to 200 degrees F.
The rule of thumb is 1 pound of brisket equals 1 hour of cook time at 250 ˚F. For 14 lbs,14 hours but more specifically..
