Smoker Time Planner
Estimate smoker time by cut and weight, with the smoker temp, target done temp, and USDA minimum for each cut.
Cook to temperature, not time. This estimate is only for planning your start time. Stalls can add hours, and every smoker runs a little different. Use a meat thermometer and go by temperature, not the clock. Whole cuts of pork and beef are safe to eat at 145°F after a 3-minute rest, but brisket and pork shoulder only get tender near 203°F because that's when the collagen breaks down. All poultry, including whole chicken, must reach 165°F.
How it works
Pick a cut and its weight, and the planner multiplies a typical minutes-per-pound figure for that cut at its usual smoker temperature. Ribs work differently: instead of scaling by weight, they run on the 3-2-1 method (3 hours smoking, 2 wrapped, 1 unwrapped to firm the bark), a fixed 330 minutes no matter how big the rack is. Every result also shows the smoker temperature, the done temperature you're actually cooking to, and the USDA minimum safe temperature for that cut.
Worked example: a 12 lb brisket at 225°F running 90 minutes per pound comes out to 1,080 minutes, or 18 hours. That's your planning number for when to light the smoker, not a promise. A 4 lb whole chicken at 275°F and 45 minutes per pound comes to 180 minutes, or 3 hours. A rack of spare ribs always plans at 5.5 hours (330 minutes) regardless of size, since the 3-2-1 method is timed in stages rather than scaled by weight.
FAQ
Why does the planner say to cook to temperature, not time?
Because smoker temps drift, outdoor weather changes airflow, and every brisket or shoulder hits a stall where the internal temperature stalls for an hour or more while moisture evaporates off the surface. Two briskets the same weight can finish an hour or two apart. Time tells you roughly when to start; a thermometer tells you when it's actually done.
Why is brisket done at 203°F when 145°F is already safe to eat?
145°F with a 3-minute rest is the USDA safe minimum, meaning any harmful bacteria are killed. But brisket and pork shoulder are full of tough collagen that only breaks down into gelatin somewhere around 200 to 205°F, which is what makes them fall-apart tender. Pulling them at 145°F would be safe but tough and chewy.
Why does whole chicken need to hit 165°F when other cuts stop at 145°F?
USDA guidance sets poultry at a straight 165°F with no rest time required, unlike whole cuts of beef and pork, which are safe at 145°F after resting 3 minutes. Poultry carries a higher risk of Salmonella and Campylobacter, so it needs the higher target regardless of how tender it already is.
What should I do if my cook is running way past the estimate?
Keep the smoker at its target temperature and wait out the stall rather than cranking the heat, which can dry out the outside before the inside catches up. If you're on a deadline, wrapping the meat in foil or butcher paper once it stalls speeds things along.
