Food blogging can be pretty frustrating at times, but especially when you’ve made a recipe that tasted great, but the photos didn’t really make the food look good. And years ago I made this Slow Cooker Balsamic Pork Roast and posted it with photos that were kind of ho-hum. The pork roast was delicious and a surprising number of people still made it, but I am SO happy to be updating the post with better photos! 

When we updated the photos we decided to skip the red onions that cooked along with the pork in the original version, but I will still include that in the recipe for anyone who was a fan of that. And I used pork loin roast for a larger roast, but you can also make this with one of those very inexpensive and lean pork sirloin tip roasts that come in a four-pack at Costco. Get out your slow cooker and make this tasty pork loin roast! You’ll love this for an easy dinner idea.

How to Make Slow Cooker Balsamic Pork Roast:

(Scroll down for actual printable recipe including nutritional information.)

  1. We started by making Rosemary and Garlic Herb Rub to season the pork roast. (Any seasonings with similar ingredients can work.)
  2. I trimmed most of the fat from the pork loin roast.
  3. Then we rubbed it on all sides with about one tablespoon of the rub.
  4. Then we heated some olive oil in a large frying pan and browned the roast well on all sides.
  5. Put the roast in the slow cooker, then deglaze the pan with the beef stock and simmer to reduce by half..
  6. Then add the balsamic vinegar, reduce heat to medium, and cook about 5 minutes.
  7. Pour the liquid over the roast in the slow cooker and cook for about 2 hours on high (or 4-5 hours on low).
  8. If you’re home turn the roast over, and cook it for about 60-90 minutes more on high. (Add sliced red onions on top of the meat if you’re using them.)
  9. The pork is done when it reaches 145F-65C on an Instant Read Meat Thermometer (affiliate link) if you want to start testing it after about 3 hours.
  10. Remove pork to a cutting board and let it rest about 5 minutes. (Cover with foil to keep warm if you like.)
  11. You might want to use a Fat Separator (affiliate link) to remove fat from the cooking sauce, or put liquid back into the frying pan and simmer to reduce for about 20 minutes so the flavor is a little more concentrated.
  12. Then slice the meat, arrange on serving plate, and serve with the sauce.  Serve hot.

Slow Cooker Balsamic Pork Roast

Yield 8 servings
Prep Time 30 minutes
Cook Time 3 hours
Total Time 3 hours 30 minutes

This Slow Cooker Balsamic Pork Roast features pork loin roast that gets tender and delicious when it’s cooked in the crockpot.

Ingredients

  • 3 lb. pork loin roast (see notes)
  • 1 T Rosemary and Garlic Herb Rub (see notes)
  • 1 T olive oil
  • 1 cup beef stock, simmered to reduce
  • 1/4 cup balsamic vinegar
  • 3 small red onions, cut into thick slices and separated into rings (optional)

Instructions

  1. We started by making Rosemary and Garlic Herb Rub to season the pork roast. If you don't have those exact spice and herb blends, any seasonings with similar ingredients can work.
  2. Trim most of the fat from the pork loin roast.
  3. Rubbed the roast on all sides with about one tablespoon of the rub.
  4. Heated the olive oil in a large frying pan and brown the roast well on all sides. (This will take 5-10 minutes; don't rush the browning step.)
  5. Put the roast in the slow cooker, then deglaze the pan with the beef stock scraping of any browned bits in the pan, and simmer and simmer until stock is reduced by half..
  6. Then add the balsamic vinegar, reduce heat to medium, and cook about 5 minutes.
  7. Pour the liquid over the roast in the slow cooker and cook for about 2 hours on high (or 4-5 hours on low)
  8. The pork is done when it reaches 145F-65C on an Instant Read Meat Thermometer (affiliate link) if you want to start testing it after about 3 hours.
  9. Remove pork to a cutting board and let it rest about 5 minutes. (Cover with foil to keep warm if you like.)
  10. You might want to use a Fat Separator (affiliate link) to remove fat from the cooking sauce, or put liquid back into the frying pan and simmer to reduce for about 20 minutes so the flavor is a little more concentrated. (Taste it and see what you think.)
  11. Then slice the meat, arrange on serving plate, and serve with the sauce.  Serve hot.

Notes

I used a Crock-Pot 2.5-Quart Slow Cooker (affiliate link) for this recipe, but a slightly larger size will work.

I originally made this with pork sirloin tip roast; use that if you prefer. I used Rosemary and Garlic Herb Rub, but similar herb blends will work.

  1. Do you warm the balsamic at high heat for 5 minutes or a lower heat?

  2. Thanks Pam! I loved it. Really liking those pork sirloin roasts from Costco.

  3. Oh this looks so good!

  4. Thanks Doren, what a nice comment. I discovered the pork sirloin at Costco, tried it because of the price, and now I'm sold on it.

  5. This looks great… don't know how I missed it last year. Have to check my Costco to see if they have that cut; I'm not familiar with it. But I'm certain I'll love it. It's typical Kalyn… great ingredients, has to be delicious!!

  6. Kelley, phase one is only two weeks, after that rice would be great!

  7. Gorgeous, Kalyn! I'd serve it over rice (I know, a no-no for SB) but those juices look too good not to! Some braised greens to go with and I think I've got a dinner covered this coming week!

  8. Hi Sally; Happy New Year to you too!

    You must get a slow cooker, and then try this recipe. I really like the pork sirloin.

  9. Happy New Year, Kalyn!

    I never cooked pork sirloin before, can you imagine THAT?

    I am not sure I've paid attention to this cut, I will have to look for it at our grocery store. Of course, I still need to get a crockpot, but that is on my list of things to get in the future….

  10. Lisa, so glad you like it, enjoy!

  11. I love using my slow cooker! Love this flavor combination! Thanks, Kalyn!

  12. Excellent recipe! I modified it slightly and cooked in a pressure cooker rather than a slow cooker. I also made a red and yellow pepper risotto that was a great addition to this dish. Thank you for sharing.

  13. Michelle, yaay! Hope things are going okay for you.

  14. I just sat down to find ways to use the pork sirloin roast that came with my meat CSA and was thrilled to see one from my friend – YOU! It sounds delicious and I just printed a copy so that I can prepare it for dinner on Sunday with the family. xoxox M

  15. I know 3 posts on 1 recipe…I made it and it was wonderful… total success. I was going to be out, and didn't want to overcook it so I put it 4 hours on low and then it auto switched to warm for 3-4 hours on warm. I added the onions when I got home, but after a half hour I couldn't wait so transferred the juice and onions to a saucepan and reduced. Added a little ginger to the rub as I didn't have the pork chop spice mix and when I looked on the Penzey website I noticed it mentioned ginger. I was able to make the other mix. Highly recommend,sliced up really nicely too, didn't shred. Thanks again!

  16. Went to Costco today and bought the roasts. I have never cooked a pork roast, so I am glad you told us what to buy. Can't wait to make it, and am happy it is a small roast. Put the other 3 in the freezer for now and can't wait to experiment with some of the other recipes later on. Thanks!

  17. Jeanne I fell on the ice and broke my arm. Ugh. But I'm getting my cast off in 8 more days, yaay!

  18. Don't you just hate that – something that tastes like heaven but looks like something the dog dragged in?? And roasts are particularly bad for that – bug brown lumps of meat! But I love this photo – makes me want to grab a fork 🙂 Sorry to hear about the arm – what did you do??

  19. This looks amazing… I am a good cook, but my weak point is pork. I love all things Costco, so I will go find it and try it. Rosemary, Balsamic vinegar, onions…love, love, love …. can't wait to make it.

  20. Glad you liked it and also good to hear it will work with a larger slow cooker.
