Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce

Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce is a lower-carb version of pulled pork that’s savory and delicious!

PIN Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce!


Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce is my lower-carb take on a classic American dish, and one reason I decided to tackle this recipe was because I find most barbecue sauce recipes to be too sweet. I wanted to see if I could come up with a low-sugar pulled pork that would suit my preference for more savory flavors, so if you try this recipe, be prepared for a sauce with plenty of mustard flavor, smokiness, and spice, and just the barest touch of sweetness.

I started with a crockpot recipe for Slow Cooker Pulled Pork that I’d spotted on Prudence Pennywise. I didn’t want a result that was super fatty, so I consulted my butcher for ideas about a lean cut of pork that would pull apart when cooked for a long time at a low temperature. I and ended up going with a pork loin roast that I cut into two pieces against the grain, so I had shreds of pork that were 3-4 inches long. (You could also use those Pork Sirloin Roasts that are such a good buy at Costco, or use boneless pork shoulder roast if you don’t care about fat.) 

I use either Heinz Low-Sugar Ketchup (affiliate link) or G. Hughes Sugar-Free Ketchup (affiliate link) as the base of my sauce. I originally made the low-sugar barbecue sauce with mostly Stevia Granulated Sweetener (affiliate link) and a bit of brown sugar for best flavor, but now that I’ve discovered Golden Monkfruit Sweetener (affiliate link) I make this with all sweetener and no brown sugar. 

Can I make this in the Instant Pot?

I do think pulled pork is the kind of recipe that’s perfect for the slow cooker, but to see how to make this in the Instant Pot, check out Instant Pot Pulled Pork with Low-Sugar Barbecue Sauce.

How to make this pulled pork in the slow cooker:

(Scroll down for complete recipe with nutritional information.)

  1. I trimmed all the outside fat off my pork loin roast, and then cut it in half against the grain. This roast was about 2.5 pounds after trimming, but next time I’d get one just a little bigger.
  2. I use either Heinz Low-Sugar Ketchup (affiliate link) or G. Hughes Sugar-Free Ketchup (affiliate link) for my low-sugar barbecue sauce. If you don’t want ketchup with artificial sweetener, look for a natural ketchup without added sugar.
  3. Mix the barbecue sauce in a measuring cup or bowl. I tasted a few times and added a little more of this or that until it tasted good to me. (The flavors will get more intense as it cooks.)
  4. Spray the crockpot with olive oil, then put the trimmed pork roast that you’ve cut in half in, pour the sauce over and cook all day on low. I used a 2.5-Quart Slow Cooker (affiliate link), so if you only have a big crockpot I’d double the amount of everything and make this a Weekend Food Prep recipe!
  5. When the meat is done enough to pull apart easily, remove from crockpot with a slotted spoon, then shred with two forks. (I ate some before I took this photo, so a two pound roast will be a little more than this!) Pork should cook about 7-8 hours, on low, depending on how hot your crockpot cooks.
  6. I thought the sauce seemed a little thin, so I took it out of the crockpot and simmered on the stove until it was reduced by about 1/3. This also concentrated the flavor just a bit more. (This step is completely optional.)
  7. You can put the shredded meat back into the crockpot with the sauce to keep it warm, or serve right away.

Make it a Meal:

Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce would be great on sandwiches, but I just ate it with a salad of shredded lettuce, shredded, cabbage, and homemade blue cheese dressing.

Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce

Yield 8 servings
Prep Time 30 minutes
Cook Time 8 hours
Total Time 8 hours 30 minutes

This Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce uses reduced sugar ketchup and your favorite sweetener to cut down on the carbs! If you have a large slow cooker, definitely double this recipe!


  • 3 lbs. boneless pork loin roast (see notes)
  • olive oil, for spraying crockpot (or use non-stick spray)
  • 1/2 cup reduced-sugar ketchup or natural ketchup without added sugar (see notes)
  • 2 T tomato paste
  • 6 T Golden Monkfruit Sweetener, or to taste (or use the sweetener of your choice)
  • 1/4 cup apple cider vinegar
  • 1/4 cup mustard (regular yellow mustard, not Dijon)
  • 2 tsp. Green Tabasco Sauce (or 1 tsp. red Tabasco)
  • 1 1/2 T Worcestershire Sauce (Be sure to look for gluten-free Worcestershire Sauce if needed.)
  • 1/2 tsp. Liquid Smoke (or more, optional but recommended)


  1. Spray slow cooker with olive oil or non-stick spray.
  2. Trim most of the visible fat from pork loin roast, then cut in half against the grain and place in slow cooker.
  3. Combine reduced sugar or natural ketchup, tomato sauce, Golden Monkfruit Sweetener (or sweetener of your choice), apple cider vinegar, mustard, Green Tabasco, Worcestershire sauce, and Liquid Smoke in measuring cup or bowl and whisk together, then pour over roast.
  4. Turn slow cooker to low and cook 7-8 hours, or until meat shreds apart easily.
  5. Use a slotted spoon to remove meat from slow cooker, and place on cutting board.
  6. Check the sauce in slow cooker and if you’d like it a bit thicker, pour sauce into small saucepan and simmer at medium-low heat until reduced by 1/3, probably not longer than 10-15 minutes.
  7. While sauce thickens, use two forks to shred apart the meat, placing back in slow cooker to keep warm if desired.
  8. When sauce is as thick as you want it, pour over meat.
  9. This can be kept warm in the slow cooker for an hour or two, or served immediately.
  10. Leftover Pulled Pork with Low-Sugar Barbecue Sauce will keep in the fridge for quite a few days and quickly reheated in the microwave or in a pan on the stove. This also freezes well.


If you trim most visible fat, the pork roast should be about 2 1/2 lbs. after trimming. For this recipe I use either Heinz Low-Sugar Ketchup or G. Hughes Sugar-Free KetchupGreen Tabasco Sauce, and Liquid Smoke (affiliate links).

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you’re making this Slow Cooker Pulled Pork with Low-Sugar Barbecue Sauce for the South Beach Diet, follow the suggestions about using pork with only 10% fat and using low-sugar ketchup and an approved sweetener to sweeten the sauce. Obviously, the sauce without the brown sugar is most diet-friendly and lowest in carbs, although the small amount of brown sugar doesn’t add much sugar per serving. I’d probably limit this to Phase 2 or 3 for South Beach and I’d use portion control if you’re actively trying to lose weight. If you use all sweetener and omit the brown sugar this could be a treat for a low-carb dieter, although even low-sugar ketchup does have some carbs.

  1. Cristy, that's great! So glad to hear it was a hit.

  2. Thanks so much Kalyn! Reducing the sauce worked perfectly. It was soooooo good! My husband said it is the "best thing I have ever cooked hands down!" YAY! Thanks again!

  3. Cristy, no worries about the questions; I am happy to help. I would put the tomato sauce in a pan on the stove and cook it until it's thick and most of the water has evaporated. If you don't do that I'd worry that the pulled pork would be rather runny.

  4. Good gracious! Are you tired of my questions yet? Don't get too tired of them because I need your help! Ha ha! So my precious sweet husband went to the store for me yesterday and could not find tomato paste so he bought tomato sauce. I think those tiny little cans hid from him. Anyway, I want to make it today but wasn't sure if the sauce would work?! HELP! Thanks so much!

  5. Emily, so glad you liked it! And it sounds like the coleslaw would be great on the side for a Christmas dinner.

  6. I found this on your Christmas Dinner list and decided to give it a go – the last time I made pork in the slow cooker it was a disaster, but I was brave.

    This. Is. Delicious. I had to modify it a bit – we don't use artificial sweeteners, so I added some honey and started with homemade ketchup from Mark Bittman's "How to Cook Everything Vegetarian." Couldn't find a 3lb roast so we only get to sop up 1.8 lbs of this treat! We're adding some of Smitten Kitchen's "Not Your Mama's Cole Slaw" and hardly had to do any work on Christmas. Thank you!

  7. Nicole, good idea; thanks for sharing!

  8. I added some Cary's sugar free syrup as a sweetener – trick I learned in a south beach baked beans recipe…yum! Thanks for another great recipe! Side note it is also really tasty when you drizzle a little of the syrup on a microwaved sweet potato!

  9. How fun to hear that this was a hit even in Germany, where this type of dish isn't traditional. So glad you liked it.

  10. Hello, I'm just ending my second week on SouthBeach and tried this recipe in my slow cooker. It was wonderful! I doubled the sauce for a 3 pound roast and it was perfect. I live in Germany and I took it to our "potluck" today…it was gone in about 10 minutes! Germans typically don't like super-sweet cuisine, so this bbq was perfect!

  11. Thanks! Especially love getting an endorsement from the one year old!

  12. I am a sucker for pulled pork and this happens to be the best one I have made. The whole family loved it, even my very picky 1 year old. HIGHLY recommend this one!

  13. I followed your original recipe (including the brown sugar *ekk* and it is so good. I did cut it up into 6 chunks and cook on high for 8 hours. My crock pot never gets anything right unless I cut it up and cook on high.

    So good. I can't wait for DH to try it and I've already shared the recipe link with my family.

  14. Thanks Kalyn….I did double the sauce recipe too and the meat was all covered with the sauce. Anyway, thanks for posting such wonderful recipes! Can't wait to try some more of them!

  15. Karen, the roast I had was only about 2 pounds, so if you didn't increase the sauce by quite a bit, that's why it would have been more dry. Glad you liked it though!

  16. Kayln, your site is unbelievable and I tried the pulled pork recipe yesterday and it's sooooooo good! I highly recommend it. I doubled the recipe and used the splenda/brown sugar product. I added a bit more spice to the sauce as well but overall it's a super delicious meal. I felt like the pork was a little dry though which is weird b/c I didn't think that was possible with a slow cooker…is it possible it cooked too long? I had about 5 lbs. cut into 4 pieces.

  17. Roberta, so glad you liked it. I've heard about those sandwich buns, but haven't seen them here. Want to try them!

  18. Made this yesterday in the slow-cooker, and it was fabulous. I love a good pulled-pork BBQ, and this hit really well right in the middle–not too tomato-y, not too sweet, not too-vinegar-y. Next time, I will use just a bit less Splenda white and a bit more Splenda brown, for a darker taste.

    I put it on one of those Arnold Sandwich Selects, a 100% whole wheat bun-sorta-thingy. I love those, and they made a good splurge when it comes to carbohydrates. With a dollop of coleslaw on top, I was a happy, happy girl!

  19. Tracey, that sounds interesting. I haven't cooked much with stevia, so it's good to know it will work in a recipe like this.

  20. This is a great idea! I did something similar lately but used stevia and blackstrap molasses to cut the carb content even more, without my having to risk getting a migraine (Splenda does that to me).
