Short answer: smoke a bone-in pork butt at a steady 225–250°F, plan on roughly 1.5 to 2 hours per pound at 225°F (so an 8 lb butt runs about 12 to 16 hours), and pull it off when the thickest part reaches about 203°F and a probe slides in like butter. Wrap it once it hits the stall, then rest it before you shred. It’s the most forgiving big cut in barbecue — a great first long cook.
Pork butt (also called pork shoulder or Boston butt) is loaded with fat and connective tissue, which is exactly why it turns into tender pulled pork when you cook it low and slow. Here’s the honest timeline, when to wrap, and the two temperatures that matter.
How long to smoke a pork butt, at a glance
Planning estimates at a steady smoker temperature. Always cook to internal temperature — a big, fatty shoulder can stall for hours, so build in a buffer.
| Smoker temperature | Approx. time per pound | Typical 8 lb butt |
|---|---|---|
| 225°F (low & slow) | ~1.5–2 hrs | ~12–16 hours |
| 250°F (our sweet spot) | ~1.25–1.5 hrs | ~10–12 hours |
| 275°F (hot & fast) | ~40–60 min | ~6–8 hours |
How to smoke a pork butt, step by step
1. Choose and trim the pork butt
Pick a bone-in pork butt around 8 lb — the bone adds flavor and tells you when it’s done (it wiggles free). Trim the fat cap down to about a quarter inch so smoke and rub reach the meat, and remove any loose, hard fat.
2. Season with a rub
Coat all sides with a simple rub — salt, black pepper, paprika and a little brown sugar is a classic, or see our best BBQ rubs and seasonings guide for ready-made options. For deeper flavor, season the night before and refrigerate uncovered; otherwise let it sit while the smoker heats up.
3. Preheat the smoker to 225–250°F
Get your smoker steady at 225°F for the most rendered, smoky result, or 250°F to finish a few hours sooner. Add a mild-to-medium smoke wood such as hickory, oak or apple once it’s holding temperature.
4. Smoke fat-side up until the stall (~160–170°F)
Set the butt fat-side up and let it ride, spritzing occasionally if you like. Around 150–170°F the internal temperature will plateau for a few hours — that’s the stall. Don’t panic and don’t crank the heat.
5. Wrap to push through the stall
Once the bark is set and dark — usually around 165–170°F — wrap the butt tightly in foil (or a foil pan) to power through the stall and lock in moisture. Butcher paper works too and keeps the bark a little firmer.
6. Cook to ~203°F and probe for tenderness
Return it to the smoker until the thickest part reads about 200–205°F. Temperature is the guide; the real test is feel — a probe should slide in with almost no resistance, and the bone should wiggle loose.
7. Rest, then pull
Rest the wrapped butt at least 30–60 minutes (longer is fine in a towel-lined cooler). Then pull out the bone, shred the meat with forks or claws, and mix the crusty bark back through. Sauce to taste.
Why pork butt “stalls” — and why that’s normal
Like brisket, pork butt hits a stall: as surface moisture evaporates it cools the meat almost as fast as the smoker heats it, so the internal temperature can sit at 150–170°F for hours. It’s completely normal on a big, fatty cut. Wrapping is the most reliable way through it; if you’d rather not wrap, just wait it out and build in extra time. (For more on this, see our brisket guide on how long to smoke a brisket.)
Is it safe? The pork temperatures that matter
Two temperatures do different jobs. The USDA’s safe minimum internal temperature for whole cuts of pork is 145°F with a three-minute rest — that’s the food-safety line for something like a pork chop or roast. But pulled pork needs to go far higher, to around 203°F (anywhere from 195–205°F), because that’s where the collagen and connective tissue break down into gelatin and the meat shreds easily. So you cook well past the safety minimum for texture — which is why an accurate thermometer is essential.
The gear that makes it easy
Pork butt is forgiving, but two things make it easier: a smoker that holds a steady temperature and a thermometer you trust.

Frequently asked questions
How long does it take to smoke a pork butt per pound?
At 225°F, plan on roughly 1.5 to 2 hours per pound. An 8 lb bone-in butt typically takes 12–16 hours; at 250°F it’s closer to 10–12 hours. Always cook to internal temperature (~203°F) rather than the clock, and wrap to speed the back half.
What temperature is pulled pork done?
About 203°F in the thickest part, though anywhere from 195–205°F works. That’s well above the USDA’s 145°F safety minimum — the extra cooking breaks the collagen down into gelatin so the meat shreds easily. If a probe slides in with no resistance, it’s ready.
Should I wrap my pork butt?
Wrapping around 165–170°F (in foil or a foil pan) pushes you through the stall faster and keeps the meat moist — ideal for pulled pork. Butcher paper keeps the bark a little firmer. You can cook unwrapped for maximum bark, but expect a longer cook.
Bone-in or boneless pork butt?
Bone-in is our pick for smoking: the bone adds flavor, helps the meat hold together, and pulls out clean when the butt is done — a handy doneness cue. Boneless cooks a touch faster and is easier to slice, but bone-in is the classic pulled-pork choice.
How long should pork butt rest?
Rest at least 30–60 minutes before shredding, and up to a few hours in a towel-lined cooler. Resting lets the juices redistribute so the pulled pork stays moist instead of drying out.
How much pulled pork per person?
Plan on about 1/3 lb of finished pulled pork per person. Pork butt loses roughly 40% of its raw weight to fat rendering and moisture, so an 8 lb raw butt yields roughly 4.5–5 lb cooked — enough for 12–15 people.
