Ingredient Substitutions
The ingredient list here is intentionally short - the low and slow cook does all the work. Here is what swaps cleanly.
- Bone-in boston butt → boneless pork butt: Both work. Bone-in delivers more flavor and the bone acts as a natural rack. Boneless is easier to shred. Cook time stays the same.
- White vinegar → apple cider vinegar: A direct swap that adds slight sweetness. Equally effective as a tenderizer.
- White vinegar → chicken or beef broth: Skips the acidity entirely, adds savory depth. The pork will be richer and less tangy.
- Dry rub → your favorite BBQ seasoning: Any rub works. Apply generously on all surfaces before searing.
- Sear → skip: The sear adds significant flavor the slow cooker cannot replicate. Skipping it is fine for a weeknight; the pork will still be tender, just with a milder flavor profile.
Step-by-Step Instructions
The slow cooker does the real work here. Your job is to season it well, get a good sear on it, and then leave it alone for 12-18 hours. The hardest part is the wait.

Make the dry rub
Combine your spices in a small bowl and mix well. This can be done the night before.

Season the pork
Pat the boston butt completely dry with paper towels - a dry surface sears better. Apply the dry rub generously on all surfaces, pressing it into every crevice.
Flavor Tip
For maximum flavor, cover and refrigerate overnight after seasoning.

Sear the pork (optional but recommended)
- Heat a large cast iron or heavy-bottomed skillet over high heat until smoking.
- Add a thin layer of high smoke-point oil.
- Place the pork butt joint side down and sear for 4-5 minutes without moving it, until deeply browned.
- The meat should release naturally from the pan when properly seared. Turn and sear all sides except the fat cap.

Transfer to the slow cooker
Place the seared pork fat side down in the slow cooker. Pour 1 cup of white vinegar into the bottom, doing your best not to wash off the rub. Place the lid on.

Cook low and slow
Set the slow cooker to low. Cook for a minimum of 8 hours, preferably 12-18 hours. The pork is ready when it reaches an internal temperature of 195-205°F and shreds easily with two forks.

Rest and pull
Remove the pork from the slow cooker and rest on a cutting board for 10-15 minutes. If bone-in, the bone should slide out cleanly with no resistance. Pull the pork into large, tender chunks using two forks or heat-safe gloves.
Add the juices back
Reserve the cooking liquid from the slow cooker. Pour a generous amount back over the pulled pork and toss to combine. This keeps the meat moist and flavorful. Serve immediately or refrigerate for later.
Storage Instructions
Pulled pork is a meal prep staple for a reason; it stores and reheats better than almost any other protein.
- Refrigerator: Airtight container with reserved cooking liquid for up to 5 days.
- Freezer: Freezer-safe bags or containers with cooking juice for up to 3 months. Thaw overnight in the refrigerator.
- Reheating: Covered skillet over medium-low heat with reserved juices or a splash of broth. Or reheat in the slow cooker on low for 1-2 hours.
- Avoid the microwave if possible - heats unevenly and dries out the meat. If you must, cover loosely, add liquid, and heat in 30-second intervals.

FAQ's and Tips
I am a huge fan of a potato roll for my pulled pork sandwiches! If you have never had a potato roll with your sandwich, do yourself a favor and try one next time. Feel free to add your favorite BBQ sauce, Vinegar Based BBQ Sauce or coleslaw to your sandwich.
I just strain the pork drippings through a mesh strainer getting out the larger bits. Keep the juices in the refrigerator, allow the fat to congeal and remove it when it solidifies. I use the drippings to help add moisture and layers of additional flavor to the pulled pork when I heat it up for service.
When cooking a Boston butt in a slow cooker for pulled pork allow a minimum of 8 hours and up to 12 hours for the meat to cook fully. The meat will fall apart easily in your hands when you pull the pork.
Both come from the upper shoulder area of the pig and are used interchangeably in most recipes. The Boston butt sits higher on the shoulder and has slightly more intramuscular fat and marbling, making it the preferred cut for pulled pork. The picnic shoulder comes from lower on the leg and has a little less fat. Either works in this slow cooker recipe; Boston butt is the better choice when available.
A boneless pork butt can be used. There are no bones to work around and the price may be higher for this convenience. But I feel like you are sacrificing flavor for convenience. Everyone has their preference.
As you know, I am a big advocate that color equals flavor especially when it comes to meat. By searing meat you are caramelizing the surface, giving it another layer of flavor to add to the pulled pork.
If you do not have time to sear the pork in a screaming hot pan before transferring the meat to the slow cooker, your pulled pork will still be delicious. Just like salt enhances the taste of food, searing pork before cooking it will enhance the flavor of the pulled pork. But you are able to do without salt and you are able to do without searing.
The USDA minimum for pork is 145°F, but at that temperature, a Boston butt will not shred - it will be cooked but firm. For fall-apart pulled pork, cook to an internal temperature of 195-205°F. At that range, the collagen has fully converted to gelatin and the fat has rendered completely. If the pork feels tough, it simply needs more time.
No, but I encourage you because the sear adds significant flavor the slow cooker cannot replicate. The high heat creates a deeply browned crust through the Maillard reaction. Skipping it gives you tender, juicy pork with a milder flavor. Including it gives you that extra depth that makes people ask what you did differently.
Two reasons: it creates steam that keeps the pork moist during the long cook, and its acidity gently tenderizes the meat and connective tissue over time. It also adds a subtle tanginess to the cooking liquid that balances the richness of the pork. The vinegar flavor mellows completely over 12-18 hours and is not detectable in the finished pulled pork.
On low, it is very hard to overcook a Boston butt. The minimum is 8 hours for a smaller cut, but 12-18 hours is ideal for a full bone-in butt. Cooking beyond 18 hours on low can cause the meat to become mushy and lose structure. On high heat it is easier to dry out - always use the low setting for this cut.
Two common causes - not enough cooking liquid in the slow cooker, and/or the lid being not tight enough, or not adding the reserved cooking juices back when shredding. Always save the liquid and pour a generous amount back over the pulled pork as you shred it. If it is already shredded and dry, warm some chicken broth or apple cider vinegar in a small pan and toss the pulled pork in it over low heat until it comes back to life.

Edit to my previous comment, cook for 18 hours
Leigh Smith says
This is a fantastic recipe, I cook for full 29 hours. I’d it possible to reduce the vinegar?
Sarah Mock says
If you want to reduce the vinegar, go for it! I would add 1/4 cup at a minimum.The vinegar does help break down and tenderize the muscle so you should keep some in the recipe. I don't actually measure a cup of vinegar... I pour in and call it a 'cup'.
Kim says
Is it 8-12 or 13-18 hours? 1/4 cup of vinegar or 1 cup of vinegar? The card vs. the blog directions differ. Thank you!
Sarah Mock says
Kim,
Thanks for the heads up. I have switched to a different recipe card and not everything transferred as it should have. I thought I caught all the glitches but I guess not. I have updated the recipe card thanks to your comment. I hope it is more clear.

Renee says
Can you cook on high in crockpot for less time ??!
Sarah Mock says
You can! I just prefer the low and slow. But I know that some people need to have dinner on the table in less time.
Briana says
How many calories is a serving? Is that 7,000 in the nutrition facts?
Sarah Mock says
Oh my goodness! I need to fix that. I have a new recipe card program and it looks like it is glitching out. Let me get on that for you. Thanks Briana!
