Overview of Smoking Times for a 4 Pound Pork Butt

As a general guideline, smoking times for pork butt range from about 1-1.5 hours per pound at 225-250°F. This means a 4 pound pork butt will likely take 4-6 hours when hot smoked at these temperatures. However, cooking times can vary significantly depending on factors like the shape and thickness of the meat, type of smoker used, and accuracy of the temperature.

It’s always best to rely on an instant read thermometer over cook times, and pull the pork when it reaches 195-205°F internally. This ensures it reaches the ideal tenderness. At this temp, the collagen melts into succulent meat that pulls apart easily. Relying solely on time can lead to dried out or undercooked pork.

Typical Smoking Timelines for a 4 Pound Pork Butt

To give you a better idea of what to expect, here are some typical timelines when smoking a 4 pound pork butt at 225-250°F:

  • Electric Smoker: 4-5 hours
  • Offset Smoker: 5-6 hours
  • Pellet Smoker: 4.5-6 hours
  • Kamado Grill: 4-5 hours
  • Kettle Grill: 5-6 hours
  • Propane Smoker: 4-5 hours

These time ranges account for the differences in heat control and airflow between various types of smokers. Well-insulated electric and kamado style smokers tend to cook faster, while offset smokers and basic kettle grills run on the slower side.

Key Factors That Affect Smoking Times

Keep in mind, there are many variables that can shorten or lengthen the smoking time for a 4 pound pork butt. Here are some of the main factors to consider:

  • Temperature of the Smoker: Lower temp (225°F) equals longer cook time. At 300°F or above, total time drops to 1-1.5 hours per pound.

  • Venting and Airflow: Restricted airflow increases time. Better airflow means faster cooking.

  • Ambient Temperature: Cold weather can significantly increase cook times.

  • Accuracy of Thermometer: A thermometer being off by 25 degrees or more will alter time.

  • Thickness and Shape Pork butts with more thickness require more time

  • Bone-In or Boneless Bone-in takes a bit longer to cook through

  • Presence of Fat Cap An untrimmed fat cap can act as insulation increasing time slightly.

  • Stall Period: The dreaded stall around 150-170°F will add 1-2+ hours to total cook time.

Step-By-Step Smoking a 4 Pound Pork Butt

To smoke pork butt like a pro, follow these simple steps:

  1. Trim: Trim excess fat, leaving about 1/4 inch. This helps prevent bitter fat flavors.

  3. Preheat Smoker: Get the smoker up to 225-250°F before putting the meat on.

  5. Maintain Temp: Keep the smoker temp steady at 225-250°F for the entire cook.

  6. Spritz and Wrap: After 3-4 hours, spritz with apple juice or broth. Wrap in foil if bark looks good.

  7. Check Temp: Start checking temp after 4 hours. Cook until 195-205°F internally.

Smoked Pork Butt vs. Smoked Pork Shoulder

Most smoked pork butt recipes call for a pork shoulder with the bones still in it. This cut of meat is also known as a Boston butt roast or a pork butt. All of these labels are for the exact same cut of pork.

It can be hard to tell, but none of them come from the pig’s butt end. Instead, they all come from the upper part of the shoulder. The muscle groups in the pork butt, also called the pork shoulder, overlap and work hard. They are held together by tight connective tissue.

That tight tissue makes this cut particularly well suited for smoking. A pork shoulder roast that wasn’t cooked low and slow to break down the muscles and connective fibers would be hard to just cut up and serve. You’d end up chewing for a long time and not getting anywhere.

By cooking the meat slowly over a wood fire for a long time, those tissues start to break down and become tender, making amazing strands of smoked pork shoulder that are very tasty.

How to Freeze Smoked Pulled Pork

You might get hungry for pulled pork a lot when you only have to feed a small family, like I do. If you find yourself in this predicament, simply freeze the leftovers!.

  • Before putting the pork in the freezer bag, let it cool to room temperature or less. When pulled pork is hot, it will steam and make water crystals in the bag. It also makes the pulled pork mushy when it’s heated up again.
  • Shred the pork before freezing. This will let you flatten the bags before putting them in the freezer. This will save space and freeze the pork faster, which means it tastes better when it’s reheated.
  • Use freezer-safe bags. Put the pork in either gallon-sized zip-top bags or freezer-safe vacuum-sealed bags and freeze them. This helps preserve freshness and cut down on freezer burn. It is also crucial during the reheating process.
  • Remove excess air in the bag. Get rid of as much air as you can in your freezer bag, whether it’s a food saver or a regular zip-top bag. This will help your meat last longer frozen.
  • Use it or lose it. If you take out enough air, frozen pulled pork will last up to 6 months in a deep freezer or 6 weeks in a fridge/freezer combo. You can keep track of your freezer bags by writing their names and dates on them.

FAQ

When to wrap a pork butt?

Temperature-wise, wrap your pork butt when it reaches between 150 and 170°F (65 to 76°C). The easiest way to check the temperature is to use a leave-in thermometer. You’ll want to stick it into the thickest part of the pork away from the bone (if applicable), as this heats up faster.

How long to let pork shoulder rest after smoking?

Allow pork butt to rest for as little as 30 minutes to as long as 5 hours; however, the ideal resting period to rest pork butt is between 1 and 2 hours. This gives the meat enough time to relax and allows the juices to redistribute throughout the meat.
