Slow Cooker Pork Shoulder with Mustard BBQ Sauce
This slow cooker pork shoulder is simmered in a homemade sweet and tangy mustard BBQ sauce until tender enough to fall off the bone. Shred it into pulled pork and reduce the remaining liquid to a delicious tangy sauce for a truly tasty treat. Serve it with classic BBQ sides or pile it on a soft roll for pulled pork sandwiches.

A Delicious Recipe for Bone In Pork Shoulder
One of my favorite recipes to serve at a large family gathering is this pulled pork shoulder with a tangy mustard based bbq sauce and some of my pan-fried sweet potato fritters.
Instead of the classic combination of apple cider vinegar, yellow mustard, and brown sugar, this bbq sauce recipe calls on balsamic vinegar, dijon mustard, and honey. It makes for a delicious mustard sauce that you’ll use on pork, chicken breasts, and even salmon.
Serve it with some of your classic recipes for barbecue sides for a meal you won’t forget.
What You’ll Need
This version of slow cooker pork shoulder is fairly easy to make and many of the ingredients for the mustard BBQ sauce may be found in a well stocked pantry or are easy to find in an average grocery store. This is half of a full pork shoulder (around six pounds). It may be labeled as a pork butt, Boston butt, or a picnic shoulder.
How To Make Slow Cooker Pork Shoulder


- Prepare the ingredients and load into the slow cooker. Chop the onion, peel and crush the garlic. Pat the pork shoulder dry and season liberally with salt and pepper. In a medium sized mixing bowl whisk together vinegar, mustard, honey, and worcestershire sauce. Pour over the pork shoulder, cover.
- Cook the pork shoulder. Set slow cooker to low and cook for 6 – 8 hours, or until fall apart tender.


- Shred the pork shoulder into pulled pork. Carefully transfer the pork shoulder from the slow cooker onto a large cutting board. Allow to rest for 5 – 10 minutes then shred the pork into eat to eat pieces and return to the empty slow cooker insert.
- Make the mustard barbecue sauce. Strain remaining liquid from the slow cooker into a medium sized saucepan. Discard the removed solids. Bring liquid to a boil over medium high heat then reduce heat to medium low. Simmer for 10 minutes or until reduced by half. In a small bowl or ramekin combine cornstarch and water, mixing thoroughly, then slowly add to the reduced sauce while whisking constantly. Bring back to a boil for 3 minutes until thickened and a glossy brown color.
- Serve. The mustard bbq sauce can be mixed with the pulled pork prior to serving or served as a sauce on the side.
Pulled Pork Shoulder in the Slow Cooker
One of my favorite ways to use a slow cooker is for cooking large cuts of meat like this bone-in pork shoulder, the ideal pulled pork meat cut. Weighing in at 12 – 18 pounds, a pork shoulder is often sold in two sections, a pork butt and a picnic shoulder. Either of which works for this recipe.
As with most large cuts of meat, I recommend using a bone-in pork shoulder. It’s a huge cut of tough, fatty meat that needs to be cooked low and slow to give the meat time to tenderize and allow the fat to render (a fancy word for melt). You’ll know it’s done when it is fall apart tender and shreds easily into pulled pork.
Unlike braising on the stovetop or in the oven, the slow cooker allows you to set it and forget it. You simply load the slow cooker up, set it to cook on low, and walk away for 6 – 8 hours. You’ll come back to a fully cooked pork roast and a house that smells good enough to eat.
Tips for Success
As with any new recipe, it’s always helpful to know a few tips beyond the recipe to help you get it done right the first time. Here are a couple of my favorites.
- Short on cook time? While the meat is usually a bit more tender when cooked low and slow for 8 – 10 hours, you can speed it up a bit and cook on high for 6 – 8 hours instead.
- How do you know the meat is done? It will be fall-apart tender. If you can easily lift and maneuver the pork shoulder as one piece, let it cook a little longer.
- Make your meat claws do double duty. I lived for a long time without meat claws, but now that I have them I love them. In addition to being great at shredding meat, they are also great for picking up and move large cuts of meat. They feel much more secure than using forks, spoons, or a pair of tongs.
- Remove fat and gristle as your shred the pork. In a large cut of meat, finding chunks of fat and gristle as you shred the pork is totally normal. I keep a trash bowl handy and set them in there as I shred through the pork.
- Add the cornstarch slurry slowly. The cornstarch slurry will thicken the sauce and give it a shiny appearance, but if you add it all at once it can turn into a gelatinous glob. Use one hand to pour the slurry in slowly, while using the other hand to continuously whisk the sauce.

Serving Suggestions
This pulled pork with a slightly sweet and tangy BBQ sauce is a great recipe to serve for a family meal. I like to serve it over mashed potatoes or polenta with classic BBQ sides like corn on the cob, mac and cheese, pasta salad, and cornbread. It’s also great piled on a soft roll for pulled pork sandwiches or stuffed into a tortilla with some coleslaw and slices of fresh avocado for pork tacos.
You can mix the sauce with the pork shoulder prior to serving or you can serve it with the sauce on the side. You can also do both, by mixing in part of it and serving the rest on the side. The choice is really up to you.

How to Store and Reheat
This pulled pork shoulder can be kept in the fridge for 3 – 5 days when stored in an airtight container. For longer storage, up to 3 months, store in the freezer.
If you are planning to save the pork for later, I recommend waiting and mixing in the barbecue sauce just prior to serving. In this case, store the BBQ sauce in its own airtight container.

Five star rating this is delicious!
For Some reason this won’t let me select a five star, but it definitely is. I would give it more stars if I could. Really enjoyed this Renee.
Can this recipe be adjusted for Instant pot?
Hi Janice!
Once upon a time I did have an instant pot and tried this recipe. It was a disaster, as the sugars in the sauce burned almost immediately. So, in true Renee fashion, I scrubbed the pan and tried again. Second time I did the roast with the onions and garlic – no sauce – and added a cup (I believe, maybe 2 cups) of water to the pot. After it was cooked through, I shredded the meat and added the sauce as needed to get the right level of seasoning. I didn’t end up putting all the sauce on the meat, but the extra was great to have on hand for drizzling on the top when serving. I do not remember the time or settings on the instant pot, but I do remember I used the basic instructions that came in the box to figure out what was best. I hope this helps. Please come back and share your results if you try it!

I added 2 granny Smith, apples, chopped up into chunks to the bottom of the pot. It adds a nice sweet flavor to the gravy! My family absolutely loves this recipe. Thank you. for sharing!!
Can you use pork loin
No, I would not use pork loin in this recipe. Pork loin doesn’t have enough fat to withstand the extended cooking times of a pressure cooker without getting over cooked – which leads to dried out meat in the end. For pork loin I would suggest One Pan Garlic Pepper Pork Dinner or Garlic Herb Pork and Potatoes.
The meat looks so tender and juicy, the sauce sounds delicious too.
Thank you! It is so good!
Ummm, this pulled pork is making me hungry even though I just ate dinner!!!
I kind of feel like I should apologize, but you’re welcome! 🙂 Haha!
I agree the slow cooker is for every time of year! These would make such good summer sliders…love, love this recipe!
You’re right! It would work very well for sliders.
