Boston butt is a flavorful and juicy cut of pork that makes for a delicious dinner.
But if you’re not sure how long to cook it at 250 degrees, then you’re in the right place!
How long should Boston butt be cooked at 250?
To achieve the best results and ensure that your Boston butt is cooked through, it should be slow-cooked at 250°F for 8 to 10 hours. If possible, check the internal temperature with a meat thermometer and make sure it has reached an internal temperature of 195°F.
Whether you’re cooking your pork in an oven or a slow cooker, learning how to cook Boston butt correctly will guarantee tender and juicy results every time!
In this article, we’ll discuss all aspects of cooking Boston Butt at 250°F – from preparation to the practical tips on making sure it’s cooked just right.

Preparing the Boston Butt
Boston butt, also known as pork shoulder, is a cut of meat that comes from the upper part of the pig’s shoulder. It is often used for slow cooking, smoking meat, and making barbecue. Before cooking, it’s important to prepare the Boston Butt properly.
Start by removing any excess fat or skin from the meat. You can leave a thin layer of fat if you like, as it will help keep the meat moist during cooking.
Next, season the Boston Butt with your favorite rub or marinade. If you’re using a dry rub, make sure to apply it generously and massage it into the meat so that it coats all sides evenly. If you’re using a marinade, place the Boston Butt in a sealable plastic bag with the marinade and let it sit in the refrigerator for at least 4 hours (or overnight) before cooking.
Bringing the Meat Temperature Up
Before you start cooking your Boston Butt at 250 degrees Fahrenheit (121 degrees Celsius), make sure that its internal temperature is around room temperature. This means taking it out of the fridge about an hour before cooking so that it can warm up a bit.
Calculating Cooking Time for a 3 lb Shoulder
Cooking time depends on several factors including size and desired doneness. For example, if you’re cooking a 3-pound pork shoulder at 250 degrees Fahrenheit (121 degrees Celsius), you should plan on allowing anywhere from 6-8 hours of cook time.
Adding Additional Time for Larger Sizes
If your Boston Butt is larger than 3 pounds or if you’re cooking multiple pieces simultaneously, then plan on adding extra cook time accordingly.
For instance, if you’re roasting two separate shoulders weighing in at around 7 pounds total weight together instead of just one piece then expect them to require roughly twice as long – between 12-16 hours.
Regularly Check Internal Temperatures
It is important when cooking Boston butt at 250 degrees to always use a meat thermometer to check for doneness.
Insert the thermometer into the thickest part of the meat, avoiding any bones, and make sure it registers at least 145 degrees Fahrenheit (63 degrees Celsius), which is the recommended minimum cooking temperature for pork.
Keep checking the internal temperature of your Boston Butt every hour or so until it reaches your desired doneness. For pulled pork, you’ll want to cook it until it reaches an internal temperature of about 190-205 degrees Fahrenheit (88-96 degrees Celsius).
Temperature Control
To keep your Boston Butt cooking evenly and prevent hot spots, ensure that your smoker/grill temperature remains constant throughout the process. Use a thermometer to monitor heat levels and make adjustments as necessary by adding more fuel or adjusting air vents.
Cooking Time
When it comes time to cook Boston Butt at 250, timing is everything. Plan on giving yourself ample time to achieve that tender and flavorful pork shoulder that we all look forward to.
There are various factors that can impact cook time on Boston Butt such as size, thickness, juiciness etc.
It’s worth noting: slow and low produces best results with most BBQ meats such as this – this process yields maximum flavor development from spices/Rubs/Marinades/Sauces while still retaining perfect texture/moisture content throughout entire cut so take care not rush through this step!
Remove from Heat when Desired Doneness is Reached
Once you’ve checked the internal temperature of your Boston Butt and found that it has reached its desired doneness level (usually around 190-205°F), remove it from heat using tongs or a sturdy spatula with good grip/heat resistance capabilities so as not to break up any nice bark formation on its exterior surface during lifting/transferring process.
Letting the Boston Butt Rest After Cooking
Before slicing or shredding the cooked Boston Butt, it’s important to let it rest for at least 10-15 minutes. This allows the juices to redistribute within the meat and results in a juicier and more flavorful end product.
Serving the Perfectly Cooked Boston Butt
Once your Boston Butt has rested, it’s time to slice or shred it into bite-sized pieces. If you’re making pulled pork sandwiches, you can either shred the meat by hand or use two forks to pull it apart.
Serve your perfectly cooked Boston Butt with your favorite barbecue sauce and sides like coleslaw, baked beans, or macaroni and cheese.
Final Thoughts
In conclusion, cooking Boston Butt at a low temperature of 250 degrees Fahrenheit is a slow process that requires proper preparation, patience and attention to detail.
To achieve that perfect blend of taste and texture we crave: season generously; check internal temperature regularly; keep heat steady throughout cooking process; allow for resting period prior to slicing/shredding. With these tips in mind anyone can create an excellent BBQ meal using this cut of meat as their centerpiece!
