Question: how long does it take to smoke a 3 pound brisket?
Answer: How Long to Smoke a Brisket. I like to plan 90 minutes for every pound of smoked brisket, including the rest or hold temperature, when cooking at 250 degrees Fahrenheit. The total cook can be anywhere from 8 hours to 16 depending on the size of the cut. It is normal that every brisket you cook will vary in time.
