Smoking a Pork Shoulder – Pulled Pork Time and Temp
Set your dinner time – we’ll plan every step backward and put it on your calendar.
Pulled pork is finished at about 203°F, and pork shoulder is the most forgiving big cut in barbecue. It carries enough fat and collagen that an extra hour rarely hurts it, which is exactly why it is the cut most people should start with.
Shoulder, butt, picnic
The terminology confuses everyone. The whole front leg is the shoulder. It splits into the Boston butt (the upper portion, well marbled, the classic pulled pork cut) and the picnic (the lower portion, leaner, with skin). Despite the name, the butt is not from the rear of the pig. If a recipe says pork butt or pork shoulder for pulled pork, it means the Boston butt.
Time and temperature
Plan on 1.5 to 2 hours per pound at 225°F. An 8 pound butt runs roughly 12 to 16 hours including the stall, so it is safer to schedule a Boston butt for the long end of that window. At 250°F you can cut that to about 1.25 to 1.5 hours per pound. Cook two smaller butts rather than one huge one if you are short on time, and if the ribs are going on the same pit, run everything at 275°F and stagger the start times so the butt goes on hours before the ribs.
What the stall looks like. Internal temperature of a big cut over a 14 hour low-and-slow cook. The flat stretch is evaporative cooling; the thermometer, not the clock, tells you where you are. Why it happens and what to do about it.
| Weight | At 225°F | At 250°F |
|---|---|---|
| 4 lb | 6 to 8 hrs | 5 to 6 hrs |
| 6 lb | 9 to 12 hrs | 8 to 9 hrs |
| 8 lb | 12 to 16 hrs | 10 to 12 hrs |
| 10 lb | 15 to 20 hrs | 13 to 15 hrs |
| Stage | Temperature |
|---|---|
| Smoker temperature | 225 to 250°F |
| Wrap through the stall | about 165°F internal |
| Done and ready to pull | 203°F (195 to 205°F) |
| Slice instead of pull | 185 to 190°F |
| Rest, wrapped in a dry cooler | 1 hour or more |
The stall and the wrap
Expect the temperature to park somewhere around 150 to 170°F for a few hours. That is evaporative cooling. Wrapping in foil pushes through it quickly and speeds the cook, at the cost of softening the bark. Butcher paper is the compromise. Riding it out unwrapped gives the best bark if you have the time.
The bone test
Target 203°F, then confirm by feel. On a bone-in butt the definitive test is the blade bone: grip it and twist. When the pork is ready the bone turns freely and pulls clean with no meat clinging to it. If it resists, the collagen has not finished rendering.
Rest before pulling
Rest for at least an hour, wrapped, in a dry cooler. This is not optional. Pulling straight off the smoker squeezes out the moisture you spent all day building. After shredding, mix the bark back through the meat and fold in the rendered juices from the wrap.
If you want sliced pork rather than shredded, stop much earlier, around 185 to 190°F, so the meat still holds together.
Frequently asked questions
What temperature is pulled pork done at?
About 203°F. On a bone-in shoulder, confirm it with the bone test: the blade bone should twist and pull out clean with no meat clinging to it.
How long does a pork shoulder take to smoke?
Roughly 1.5 to 2 hours per pound at 225°F, so 12 to 16 hours for an 8 pound butt. At 250°F expect about 1.25 to 1.5 hours per pound.
What is the difference between pork butt and pork shoulder?
The shoulder is the whole front leg. The Boston butt is its upper, better marbled portion and the standard pulled pork cut; the picnic is the leaner lower portion. Despite the name, the butt is not from the rear of the pig.
Do I have to rest pulled pork?
Yes, at least an hour wrapped in a dry cooler. Shredding immediately drives out the moisture that makes pulled pork juicy.
