It typically takes about 8–16 hours to smoke a pork butt, depending mainly on the meat’s weight and your smoker temperature, and you should cook to internal temp (around 200–205°F for pulled pork) rather than just by the clock.

Quick Scoop

  • At 225°F: plan about 2 hours per pound.
  • At 250°F: plan about 90 minutes per pound.
  • At 275°F: plan about 1 hour per pound.
  • Common total times:
    • 5 lb butt: ~8–10+ hours.
* 8 lb butt: ~12–16 hours.

* 10 lb butt: ~10–20 hours (range depends a lot on temp and stall).
  • Target internal temp:
    • 185°F–190°F for slicing.
* 200°F–205°F for tender pulled pork.
  • Safety minimum: pork is safe at 145°F, but not tender enough to pull until around 200°F.

Time by Temperature (Rule of Thumb)

Here’s a simple way to estimate “how long does it take to smoke a pork butt” before you start:

  • 225°F (classic low-and-slow)
    • About 2 hours per pound.
* Example: 8 lb butt ≈ 16 hours, but could finish anywhere from ~12–18 hours.
  • 250°F (slightly faster, still very juicy)
    • About 1.5 hours per pound.
* Example: 8 lb butt ≈ 12 hours.
  • 275°F (hot-and-fast style)
    • Around 1 hour per pound.
* Example: 8 lb butt ≈ 8 hours.

These are estimates; the connective tissue and fat render at their own pace, and some butts “stall” longer than others around 150–165°F.

Typical Weight Examples

Pork butt size Smoker temp Estimated cook time Notes
5 lb 225°F ~10 hours Some guides list ~6–10 hours depending on method and wrapping.
8 lb 225°F ~16 hours Common estimate is 2 hours per pound.
10 lb 225°F ~20 hours Many pitmasters plan 18–20 hours including stall.
10 lb 250°F ~15 hours Using ~90 minutes per pound.
10 lb 275°F ~10 hours Faster “hot-and-fast” style.

Time vs. Temperature vs. Doneness

Most BBQ folks agree that smoking a pork butt is done “when it’s done” — meaning when it hits the right internal temperature and tenderness, not a precise time.

  • Internal temperature goals:
    • 160–170°F: often where the stall happens; many people wrap in foil or butcher paper here to push through.
* 185–190°F: good for slicing.

* 200–205°F: perfect for pulled pork, very tender and shreddable.
  • Tenderness test:
    • Bone wiggles and pulls out easily, or a probe slides in with almost no resistance (like warm butter).

So the real answer to “how long” is: estimate the window, then watch your internal temp and texture.

Simple Timeline Example (8 lb Butt at 250°F)

This is just an illustration of a fairly typical day with a medium butt at a moderate temp.

  1. Hour 0
    • Butt goes on the smoker at 250°F.
  2. Hours 1–4
    • Temp climbs steadily, bark starts forming.
  3. Hours 4–6
    • Internal temp hits ~160–170°F and “stalls.”
    • Many people wrap at this point to speed things up and protect the bark.
  1. Hours 6–10
    • Wrapped butt climbs slowly to 200–205°F.
  2. After cooking
    • Rest 30–60 minutes (still wrapped) before pulling.

Total active smoke time: roughly 8–12 hours depending on how long the stall lasts and your specific smoker.

Different Styles and Opinions (Forum-Style Take)

If you browse current BBQ forums and recipe sites, you’ll see a few common viewpoints:

  • Low-and-slow purists
    • Prefer 225°F, don’t mind 14–20 hours on the smoker for a big butt.
  • Hot-and-fast fans
    • Run 250–275°F to finish in 6–10 hours and say the meat is just as juicy, especially if wrapped and rested well.
  • “Forget the clock” crowd
    • Use time only for planning, then rely solely on internal temperature and feel to decide when to pull the meat.

In 2026, that “2 hours per pound at 225°F” rule is still a widely shared starting point, but most cooks also stress using a good thermometer and being flexible with your schedule.

Quick Planning Tips

  • Start early and allow a big buffer (2–4 extra hours) so you’re not serving late; you can always hold the butt wrapped in a warm cooler for a while if it gets done early.
  • Use time-per-pound only as a rough guide; aim for 200–205°F internal and probe-tender for pulled pork.
  • For an average 7–8 lb pork butt, expect a full day: about 8–16 hours depending on your chosen temp and whether you wrap.
