How Long to Smoke a Pork Butt?

Time by weight and smoker temperature

Rough rule per pound: 1.5–2 hours at 225°F, 1.25–1.5 hours at 250°F, and about 1 hour at 275°F.

Which temperature should you use?

• 225°F — the traditional low-and-slow choice. Best bark and smoke flavour, but it's a long day.
• 250°F — the practical sweet spot most pitmasters land on. Noticeably faster with almost no loss in quality.
• 275°F — a "hot and fast" cook. Still produces excellent pulled pork and cuts hours off, with a slightly less developed bark.

The target internal temperature — the number that actually matters

• 195°F — sliceable, just starting to pull.
• 200–205°F — the sweet spot for pulled pork. Collagen has fully rendered into gelatin and the meat shreds effortlessly.
• Above 210°F — risks drying out and turning mushy.

The real test isn't the number but the feel: a probe or skewer should slide into the thickest part with almost no resistance, like pushing into softened butter. If it fights back, give it more time regardless of what the thermometer says.

The stall — plan for it. Somewhere around 150–170°F, the internal temperature will stop rising, sometimes for several hours. This is evaporative cooling: moisture escaping the surface cools the meat as fast as the smoker heats it. It's completely normal, and panicking is the most common beginner mistake.

Your options:

• Wait it out — it will break through on its own, and this gives the best bark.
• The Texas crutch — wrap tightly in foil (fastest, softens the bark) or butcher paper (slower, preserves more bark) once the bark has set and the colour looks right, usually around 160–170°F. This can save 2–3 hours.

Timeline for a typical 8 lb pork butt at 250°F

1. Night before: trim the fat cap to about ¼ inch, apply a binder (mustard or oil) and a rub, and refrigerate uncovered.
2. Preheat the smoker to 250°F. Fruit woods (apple, cherry) and hickory work well.
3. Smoke unwrapped for roughly 6 hours, until the internal temp is around 165°F and the bark is dark and set.
4. Wrap in butcher paper or foil.
5. Continue until 200–205°F internal — around another 4 hours.
6. Rest for at least 1 hour, up to 4, wrapped and in a dry cooler. This is not optional.
7. Pull by hand or with forks, discarding the excess fat.

Always give yourself a buffer. Pork butt is unpredictable — two identical cuts can finish hours apart. Plan to finish 2 hours early and hold it wrapped in a cooler; it will stay hot and safe for 3–4 hours and, if anything, improves.

Bone-in or boneless? Bone-in takes slightly longer but is more forgiving and more flavourful. When it's done, the blade bone should pull out cleanly with no resistance — the most satisfying doneness test there is.

A note on names: pork butt (also called Boston butt) is not from the rear at all — it's the upper shoulder. Picnic shoulder is the lower portion and cooks a little faster.
