How long to smoke a 10 lb pork butt
A 10 lb pork butt takes about 12.5 to 15 hours at 250°F. Pull it at 195 to 205°F, then rest 1 to 2 hours.
Time is a range because every smoker, cut and day is different. Use the thermometer, not the clock, to decide when it is done.
Time at each smoker temperature
| Smoker temp | Total time |
|---|---|
| 225°F | 17.5 to 20 hours |
| 250°F | 12.5 to 15 hours |
| 275°F | 10 to 12.5 hours |
When to start
Working back from dinner at 250°F, including the rest. The first column plans for the slow end of the range so the meat is not late; the second is the fastest it could finish.
| Serve at | Start by (slow end) | Latest start (fast end) |
|---|---|---|
| 12:00 PM | 7:00 PM the day before | 10:45 PM the day before |
| 5:00 PM | 12:00 AM | 3:45 AM |
| 6:00 PM | 1:00 AM | 4:45 AM |
| 7:00 PM | 2:00 AM | 5:45 AM |
If the meat finishes early, wrap it in foil and a towel and hold it in a cooler, keeping it above 140°F, rather than letting it sit out.

Tip for a 10 lb pork butt
The stall hits around 150 to 170°F. Many cooks wrap in foil or butcher paper at that point to push through it and keep the meat moist.
Safe minimum temperatures: USDA FSIS Safe Minimum Internal Temperature Chart. Smoker temperature guidance: USDA FSIS, Smoking Meat and Poultry. Smoking times vary with the smoker, the weather, how much the meat weighs, how thick it is and whether you wrap it. These are ranges based on common barbecue practice, not lab measurements. Always cook to the internal temperature, measured with a food thermometer.
