Pork shoulder, also known as Boston butt (even though it comes from the shoulder), is a barbecue staple. Its rich marbling and connective tissue make it ideal for low and slow cooking, resulting in incredibly tender and flavorful pulled pork. But the million-dollar question is: how long does it actually take to cook a pork shoulder on the grill? The answer, as with most things barbecue, is “it depends.” This comprehensive guide will break down all the factors influencing cooking time and equip you with the knowledge to grill a perfect pork shoulder every time.
Understanding the Variables: Factors Affecting Grilling Time
Several variables impact how long it takes to cook a pork shoulder on the grill. Knowing these factors will help you estimate cooking time accurately and adjust your strategy as needed.
The Size of the Pork Shoulder
Perhaps the most obvious factor is the size of the pork shoulder itself. A larger shoulder will naturally take longer to cook than a smaller one. Generally, pork shoulders range from 6 to 10 pounds. As a rule of thumb, plan for about 1.5 to 2 hours of cooking time per pound at a consistent temperature of 225-250°F (107-121°C). This is just an estimate, and the actual time can vary, but it’s a good starting point.
Grill Temperature: Maintaining Consistent Heat
Maintaining a consistent grill temperature is crucial for even cooking and predictable results. Aim for a temperature between 225-250°F (107-121°C). Lower temperatures will extend the cooking time, while higher temperatures can lead to a dry exterior before the interior is fully cooked. Using a reliable grill thermometer is essential. Also, be mindful of external factors like wind and ambient temperature, which can affect your grill’s temperature.
Type of Grill: Charcoal vs. Gas vs. Smoker
The type of grill you use will also influence the cooking time. Charcoal grills and smokers typically impart a more intense smoky flavor, but they can be more challenging to maintain a consistent temperature compared to gas grills. Gas grills offer more precise temperature control, but they may lack the same level of smoky flavor. If using a gas grill, consider using wood chips in a smoker box to add smoke.
“The Stall”: A Barbecue Mystery
“The Stall” is a phenomenon where the internal temperature of the pork shoulder plateaus for an extended period, often between 150-170°F (66-77°C). This happens due to evaporative cooling as moisture is drawn to the surface of the meat and evaporates. Don’t panic! It’s a normal part of the cooking process. Patience is key, or you can use the “Texas Crutch” to speed things up (more on that later).
The Cooking Process: Step-by-Step Guide
Here’s a detailed step-by-step guide to grilling a pork shoulder, including estimated timelines and tips for success.
Preparation: Seasoning and Trimming
Start by trimming any excess fat from the pork shoulder, leaving about ¼ inch of fat cap. This will render during cooking and keep the meat moist. Next, generously season the pork shoulder with your favorite dry rub. A blend of salt, pepper, paprika, garlic powder, onion powder, and brown sugar is a classic choice. Apply the rub at least an hour before grilling, or preferably overnight, to allow the flavors to penetrate the meat.
Setting Up Your Grill: Indirect Heat is Key
The key to grilling a pork shoulder is indirect heat. This means cooking the meat away from the direct flame or heat source.
- Charcoal Grill: Arrange the charcoal on one side of the grill, leaving the other side empty. This creates a hot zone and a cool zone.
- Gas Grill: Turn on the burners on one side of the grill and leave the other side off.
- Smoker: Follow the manufacturer’s instructions for setting up your smoker for low and slow cooking.
Add wood chunks or chips to the charcoal or smoker box to generate smoke. Hickory, apple, or pecan wood are all excellent choices for pork.
Grilling Time: Monitoring Temperature and Smoke
Place the pork shoulder on the cool side of the grill, away from the direct heat. Insert a meat thermometer into the thickest part of the shoulder, avoiding bone. Close the lid and maintain a consistent temperature of 225-250°F (107-121°C).
Expect the initial cooking phase to take around 4-6 hours. During this time, monitor the grill temperature and add more fuel (charcoal or wood) as needed to maintain the desired temperature. Also, replenish the wood chips or chunks to maintain a consistent smoke flavor.
Conquering “The Stall”: The Texas Crutch
Once the internal temperature of the pork shoulder reaches around 150-170°F (66-77°C) and the stall occurs, you have a few options:
- Patience: You can simply wait it out. The stall will eventually break, but it can take several hours.
- The Texas Crutch: This involves wrapping the pork shoulder in aluminum foil or butcher paper. This helps to retain moisture and speed up the cooking process. To do this, remove the pork shoulder from the grill, wrap it tightly in foil or butcher paper with a splash of apple juice or broth, and return it to the grill.
Wrapping the pork shoulder can reduce the overall cooking time by several hours.
The Final Stretch: Achieving Tenderness
Continue cooking the pork shoulder until it reaches an internal temperature of 203-205°F (95-96°C). At this temperature, the connective tissue will have broken down, resulting in incredibly tender and pull-apart meat. Use a probe thermometer to check for tenderness. The probe should slide into the meat with little to no resistance.
Resting: The Secret to Juicy Pulled Pork
Once the pork shoulder is cooked to temperature, remove it from the grill and let it rest, still wrapped in foil or butcher paper, for at least one hour, or preferably two. This allows the juices to redistribute throughout the meat, resulting in a more flavorful and juicy final product. You can rest it in a cooler wrapped in towels to keep it warm longer.
Pulling the Pork: Serving Time
After resting, unwrap the pork shoulder and shred it with two forks or meat claws. Remove any large pieces of fat or bone. Mix the pulled pork with your favorite barbecue sauce, or serve it plain with sauce on the side.
Estimating Total Grilling Time: Putting it All Together
While the exact cooking time will vary depending on the factors mentioned above, here’s a general guideline:
- Unwrapped Pork Shoulder (6-8 pounds): 12-16 hours at 225-250°F (107-121°C)
- Wrapped Pork Shoulder (6-8 pounds): 8-12 hours at 225-250°F (107-121°C)
- Resting Time: 1-2 hours
Remember, these are just estimates. Always rely on a meat thermometer to determine when the pork shoulder is fully cooked.
Troubleshooting: Common Issues and Solutions
Even with the best planning, you may encounter some challenges during the grilling process. Here are some common issues and how to address them:
- The grill temperature is too high: Adjust the vents on your charcoal grill or lower the burner settings on your gas grill.
- The grill temperature is too low: Add more charcoal or wood to your charcoal grill or increase the burner settings on your gas grill.
- The pork shoulder is drying out: Wrap the pork shoulder in foil or butcher paper, or spritz it with apple juice or vinegar every hour.
- The stall is lasting too long: Be patient! If you’re short on time, wrap the pork shoulder in foil or butcher paper.
- The pork shoulder is not tender enough: Continue cooking until it reaches an internal temperature of 203-205°F (95-96°C) and the probe slides in easily.
Tips for Success: Mastering the Art of Grilling Pork Shoulder
Here are some additional tips to help you grill a perfect pork shoulder:
- Use a reliable meat thermometer: This is the most important tool for ensuring that the pork shoulder is cooked to the correct temperature.

What is the ideal internal temperature for a perfectly grilled pork shoulder?
The ideal internal temperature for a perfectly grilled pork shoulder is between 203°F and 205°F (95°C to 96°C). This range ensures that the collagen and connective tissues break down properly, resulting in a tender, pull-apart texture. Using a reliable meat thermometer is crucial for accurate temperature readings.
It’s important to remember that temperature is only one indicator of doneness. The “probe test” is equally valuable. Insert a thermometer probe into the thickest part of the shoulder; it should slide in with little to no resistance. If it feels like poking butter, your pork shoulder is ready, even if the temperature is slightly below 203°F.
How long will it generally take to grill a pork shoulder?
The general timeframe for grilling a pork shoulder can vary significantly depending on the size of the shoulder, the cooking temperature, and the type of grill you’re using. A good rule of thumb is to plan for approximately 1.5 to 2 hours per pound when grilling at a low and slow temperature of around 225°F (107°C).
Therefore, a 8-pound pork shoulder could take anywhere from 12 to 16 hours to reach the desired internal temperature and tenderness. Remember, this is just an estimate. Monitoring the internal temperature and performing the probe test are the best ways to determine doneness. Factors like wind and ambient temperature can also impact cooking time.
What type of grill is best for grilling a pork shoulder?
Both charcoal and gas grills can be used to successfully grill a pork shoulder, but each has its own advantages. Charcoal grills tend to impart a more smoky flavor to the meat, which many people find desirable. Using wood chunks, such as hickory or applewood, can further enhance the smoky flavor.
Gas grills offer more precise temperature control, making it easier to maintain a consistent low and slow cooking environment. While they don’t naturally produce the same level of smoke as charcoal, you can add wood chips in a smoker box or foil pouch to achieve a similar effect. Ultimately, the “best” grill depends on your personal preference and grilling experience.
Should I wrap my pork shoulder during the grilling process?
Wrapping your pork shoulder in butcher paper or aluminum foil, often referred to as the “Texas Crutch,” is a common technique to speed up the cooking process and help retain moisture. This is typically done when the internal temperature of the pork shoulder reaches around 150°F to 170°F (65°C to 77°C).
By wrapping the shoulder, you create a steamy environment that helps break down the connective tissue more efficiently and prevents the surface from drying out. While wrapping can soften the bark (the flavorful crust on the outside), many find the trade-off for a shorter cooking time and more tender result worthwhile. You can unwrap the shoulder for the last hour of cooking to firm up the bark if desired.
What are some tips for keeping the pork shoulder moist during grilling?
Besides wrapping, there are several ways to keep your pork shoulder moist during grilling. Maintaining a consistent low temperature is crucial; high heat can dry out the meat quickly. Aim for a grill temperature of around 225°F (107°C).
Using a water pan in your grill can also help to increase humidity and prevent the pork shoulder from drying out. Spritzing the pork shoulder with apple juice, vinegar, or a similar liquid every hour or two can also add moisture and flavor. Finally, avoid opening the grill lid too frequently, as this can release heat and moisture.
What kind of wood should I use for smoking a pork shoulder?
The type of wood you use for smoking a pork shoulder can significantly impact its flavor profile. Hickory is a popular choice for pork, imparting a strong, smoky, bacon-like flavor. It’s a good all-around option that pairs well with the richness of pork shoulder.
Applewood is another excellent choice, providing a milder, sweeter, and fruitier smoke flavor. It’s a good option if you prefer a less intense smoky taste. Other suitable woods include pecan, cherry, and oak. Experimenting with different wood types is a great way to discover your preferred flavor combinations.
What is the best way to rest a grilled pork shoulder?
Resting a grilled pork shoulder is essential for allowing the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. After removing the shoulder from the grill, wrap it loosely in foil or butcher paper and let it rest for at least one hour, but ideally two to four hours.
A longer rest allows the muscle fibers to relax and reabsorb the moisture that was expelled during cooking. You can even rest the pork shoulder in a faux cambro (an insulated cooler) to maintain its temperature for several hours. This step is often overlooked but makes a significant difference in the overall quality of the final product.
