How Long to Smoke a Pork Butt: A Complete Guide to Perfectly Cooked BBQ Pork Shoulder

Smoking pork butt—more commonly known as pork shoulder or pork butt—is a time-honored tradition in barbecue culture. Whether you're preparing a family feast or mastering the art of slow smoking, timing is crucial to achieving tender, juicy, and flavorful results. If you’ve ever wondered, “How long do you smoke a pork butt?” this comprehensive guide will walk you through everything you need to know—factors influencing cooking time, step-by-step smoking process, and tips for perfection.


Understanding the Context

What Is a Pork Butt?

The pork butt, or shoulder, is a tough but incredibly flavorful cut from the pork’s shoulder area. It’s ideal for smoking because the marbling of fat and connective tissues breaks down slowly at low heat, resulting in rich, melt-in-your-mouth meat. Pork butt is the go-to choice for beginners and experts alike, especially for slow-smoked dishes like pulled pork.


How Long to Smoke a Pork Butt: The Ideal Smoking Time

Key Insights

Short Answer: Smoke a pork butt between 6 to 10 hours, depending on weight, cut, and desired doneness. A general rule is 20 to 22 minutes per pound at a low and slow temperature of 195°F to 205°F (90°C to 96°C).


Factors That Affect Smoking Time

  • Weight and Size: Larger pork butts (8–10 lbs) take longer—around 8 to 10 hours. Smaller, trimmed choices may reach 6–7 hours.
  • Cut and Marinade: Fresh, unmarinated pork contrasts with pre-marinated or rubbed pork, affecting cooking dynamics.
  • Smoking Temperature: Sticky, low heat ensures even cooking without drying out the meat. Too high, and fabric develops; too low, and it risks food safety concerns.
  • Type of Smoker: Pellet, electric, offset, or offset barbacoa smokers all vary slightly in control and distribution.
  • Internal Temperature: Use a meat thermometer to verify doneness—not just time.

Final Thoughts

Step-by-Step Smoke Guide

  1. Prepare the Pork
    Remove any casing, trim excess fat if desired, and rub your chosen spice mix or apply a moist marinade (2–24 hours ahead). Dry the meat with paper towels before smoking to promote browning.

  2. Set Up Your Smoker
    Preheat to 195°F–205°F. Use wood chunks (hickory, oak, or apple are classic) in the smoker for authentic flavor.

  3. Smoke the Pork
    Place the pork on the smoker rack, close the lid, and let it cook slowly. Restime to 20–22 minutes per pound. For an 8-pound pork butt, aim for 160–176 minutes total.

  4. Check Internal Temperature
    Pull pork when it reaches 190°F–200°F (88°C–93°C) internal. Let it rest 20–30 minutes post-smoking to allow juices redistribute.

  5. Slice and Enjoy
    Use two forks to slice against the grain for tender pulled pork. Baste with BBQ sauce if desired or serve as-is.


Safe Time References for Doneness

  • Charcuterie-style: 200°F–205°F for 6–7 hours – tender with appealable fat melt.
  • Pulled pork: 190°F–200°F for 8–10 hours – ideal for shredding and cutting.
  • Safety note: Cook to at least 145°F with a 3–4 minute rest to kill pathogens, especially in thick cuts.
