Few things are as satisfying as a perfectly cooked pork shoulder, especially when it transforms into mouth-watering, fall-apart pulled pork. Whether you’re planning a backyard BBQ, a cozy family dinner, or meal prepping for the week, an 8-pound pork shoulder (also known as pork butt or Boston butt) is a fantastic choice. But the big question always looms: how long does it actually take to cook this magnificent cut to tender perfection?
Don’t worry, we’re here to demystify the process! While there’s no single “magic number” due to varying factors like your oven, slow cooker, or smoker, we’ll give you clear guidelines and pro tips to ensure your 8lb pork shoulder comes out incredibly juicy and tender every single time.

The Secret to Tender Pork Shoulder: Internal Temperature
For pork shoulder that’s ready to shred effortlessly, you’re aiming for an internal temperature between 195°F and 205°F (90°C to 96°C). This temperature allows the connective tissues in the meat to break down beautifully, yielding that signature melt-in-your-mouth texture. Forget the old rules about pork being done at 145°F; that’s for slicing, not shredding.
Always use a reliable meat thermometer inserted into the thickest part of the meat, avoiding the bone.
Cooking Methods & Timelines for Your 8lb Pork Shoulder
Let’s break down the approximate cooking times for an 8lb pork shoulder across popular methods:
1. Oven Roasting (The Classic Choice)
The oven is a reliable and hands-off way to achieve fantastic results. Slow and low is the name of the game here.
- At 275°F (135°C): Expect 8-10 hours. This is a very forgiving temperature that ensures maximum tenderness.
- At 300°F (149°C): Plan for 6-8 hours. A slightly quicker option still yielding great results.
- At 325°F (163°C): Budget 5-7 hours. This will cook faster, but you’ll need to monitor it more closely to prevent drying out.
Oven Tips:
- Prep: Pat your pork shoulder dry and apply your favorite rub generously.
- Sear (Optional): For extra flavor and a nice crust, sear the pork on all sides in a hot, oven-safe pan before roasting.
- Cover: Place the shoulder in a Dutch oven or a roasting pan, covered tightly with foil. This traps moisture and helps the meat steam and tenderize.
- Liquid: Add a cup or two of broth, water, or apple cider to the bottom of the pan to create a moist environment.
2. Slow Cooker (Effortless & Convenient)
The slow cooker is your best friend for set-it-and-forget-it convenience, guaranteeing tender pork with minimal fuss.
- On LOW: Cook for 8-10 hours. This is the ideal setting for an 8lb shoulder, allowing for gradual breakdown of connective tissue.
- On HIGH: Cook for 6-8 hours. If you’re short on time, this setting works, but keep an eye on it to ensure it doesn’t dry out.
Slow Cooker Tips:
- Don’t Overfill: Ensure the 8lb shoulder fits comfortably in your slow cooker (typically a 7-quart or larger).
- Add Liquid: A cup of broth, apple cider vinegar, or even soda (like root beer) adds moisture and flavor.
- Season Well: Rub the pork generously with your preferred spices before adding it to the slow cooker.
3. Smoker (For Unbeatable Flavor)
If you’re after that authentic, smoky pulled pork flavor, the smoker is the way to go. Be prepared for a longer cooking process, but the results are absolutely worth it.
- At 225-250°F (107-121°C): Anticipate 10-14 hours. A good rule of thumb is 1.5-2 hours per pound.
Smoker Tips:
- Wood Choice: Hickory, apple, cherry, or oak wood chunks/chips are excellent choices for pork.
- The “Stall”: Don’t panic if your pork’s temperature seems to stop rising (the “stall”). This is normal as moisture evaporates from the surface. You can power through it or wrap the pork in butcher paper or foil (the “Texas Crutch”) to speed things up.
- Spritzing: Periodically spritz the pork with apple cider vinegar, apple juice, or water to keep it moist and promote a nice bark.
4. Instant Pot (The Quick Solution – with a Catch!)
While an Instant Pot is fast, an 8lb pork shoulder is simply too large to cook whole in most models. For this method, you’ll need to cut the shoulder into smaller, manageable chunks (e.g., 2-3lb pieces).
- Pressure Cook Time: For 2-3lb chunks, cook on high pressure for 60-75 minutes.
- Release: Always allow for a natural pressure release for at least 15 minutes before manually releasing any remaining pressure. This helps keep the meat tender.
Instant Pot Tips:
- Cut It Up: This is non-negotiable for an 8lb shoulder in an Instant Pot.
- Sear First: Use the “Saute” function to sear the pork chunks before pressure cooking for added depth of flavor.
- Liquid: You’ll still need about 1-1.5 cups of liquid in the Instant Pot for pressure to build.
Essential Tips for Pork Shoulder Success
- Always Rest the Meat: This is CRUCIAL! Once cooked, transfer the pork shoulder to a cutting board, tent it loosely with foil, and let it rest for at least 30-60 minutes (longer for larger cuts). This allows the juices to redistribute, resulting in incredibly moist and flavorful meat.
- Invest in a Good Meat Thermometer: Seriously, this is your best friend. Don’t guess; measure.
- Bone-In vs. Boneless: Bone-in pork shoulder tends to be more flavorful and can be slightly more forgiving, but it also takes a bit longer to cook. Boneless cooks a little faster and is easier to handle.
- Prep & Season Generously: Pat the pork dry with paper towels before applying your rub. This helps the rub adhere and creates a better crust. Don’t be shy with seasoning!
- The “Probe Test”: For ultimate tenderness, the meat thermometer should slide into the meat with very little resistance, feeling like it’s going into warm butter.
- Shredding vs. Slicing: Remember, 195-205°F is for shredding. If you want to slice your pork shoulder (like for a roast), aim for 160-170°F (71-77°C) and then rest it.
Common Questions & Troubleshooting
“My pork shoulder is tough, what went wrong?”
Most likely, it didn’t cook long enough or reach a high enough internal temperature. Toughness usually means the connective tissues haven’t fully broken down. Keep cooking until it hits that 195-205°F range and feels fork-tender.
“My pork shoulder is dry.”
This can happen if it was cooked at too high a temperature for too long without enough moisture, or if it wasn’t rested properly. Covering the meat and adding liquid to the cooking vessel (especially in the oven or slow cooker) helps immensely.
“What if my pork is done early or running late?”
If done early, you can hold a cooked pork shoulder, wrapped in foil and towels, in an insulated cooler for several hours. If running late, slightly increase the cooking temperature by 25°F or use the Instant Pot method for pre-cut chunks if you’re really in a rush.
