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 balsamic pork roast was delicious and a surprising number of people still made it, but today 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 include that as an option in the recipe for anyone who was a fan of that.
I used pork loin roast for the updated recipe, which made 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 balsamic pork roast! You’ll love this for an easy dinner idea.

How to Make Slow Cooker Balsamic Pork Roast:
(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)
- We started by making Rosemary Garlic Seasoning to season the pork roast. (Any seasonings with similar ingredients can work.)
- I trimmed most of the fat from the pork loin roast.
- Then we rubbed it on all sides with about one tablespoon of the rub.
- Then we heated some olive oil in a large frying pan and browned the roast well on all sides.
- Put the roast in the slow cooker, then deglaze the pan with the beef stock and simmer to reduce by half..
- Then add the balsamic vinegar, reduce heat to medium, and cook about 5 minutes.
- Pour the liquid over the roast in the slow cooker and cook for about 2 hours on high (or 4-5 hours on low).
- 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.)
- The pork is done when it reaches 145F-65C on an Instant Read Meat Thermometer (affiliate link); start testing it after about 3 hours.
- Remove pork to a cutting board and let it rest about 5 minutes. (Cover with foil to keep warm if you like.)
- 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.
- Then slice the meat, arrange on serving plate, and serve with the sauce. Serve hot.
Make it a Low-Carb Meal:
The Balsamic Pork Roast would taste great with Cauliflower Gratin, Roasted Turnips, or Garlic-Roasted Green Beans for a low-carb meal.

- Then add the balsamic vinegar, reduce heat to medium, and cook about 5 minutes.

- Remove pork to a cutting board and let it rest about 5 minutes. (Cover with foil to keep warm if you like.)
- 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.)
- Then slice the meat, arrange on serving plate, and serve with the sauce. Serve hot.
Notes
I used a Crock-Pot 3 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 Garlic Seasoning, but similar herb blends will work.

My husband doesn’t like balsamic vinegar, would you make this with another vinegar such as red wine or white wine?
I’m not sure if that will be too sour? If you do I would probably use less vinegar or add some sweetener.
Jumping back on this old post with a question! I love this recipe but my Costco no longer sells this particular roast (how I miss that 4-pack!). Have you ever tried it with another type of pork roast? Maybe a shoulder??
I haven’t tried it with any other kind of pork roast. I wish I knew about pork roast to make a recommendation, I would ask the butcher what other type of roast they think would work to replace pork sirloin tip roast in a recipe and see what they say. Glad you’ve enjoyed the recipe.
Never mind just re-read the recipe. THanks!
Ha, I edited it since I got your comment. But glad it's now clear!
Do you warm the balsamic at high heat for 5 minutes or a lower heat?
Good question; I would reduce the heat to about medium for the vinegar. I'll edit to clarify that!
Thanks Pam! I loved it. Really liking those pork sirloin roasts from Costco.
Oh this looks so good!
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.
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!!
Kelley, phase one is only two weeks, after that rice would be great!
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!
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.
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….
Lisa, so glad you like it, enjoy!
I love using my slow cooker! Love this flavor combination! Thanks, Kalyn!
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.
Michelle, yaay! Hope things are going okay for you.
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
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!
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!
Jeanne I fell on the ice and broke my arm. Ugh. But I'm getting my cast off in 8 more days, yaay!
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??
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.
Glad you liked it and also good to hear it will work with a larger slow cooker.
We started the pork in our slow cooker (a pretty big one), and went out to shop for a new stove. When we got back, the roast smelled so good! I added the onions while we got settled/fed the dogs. Because the cooker was big, the onions didn't submerge, and I just cooked them in liquid while it simmered down. I was lovely, tasty, and the onions just make the sauce. Tomorrow I'll make a sandwich with the pork and the drained onions – yum.
I think you could do this with just garlic salt and some rosemary, but the rubs added flavor, and the sauce kept the meat from drying into wood. Thank you for a great and timely recipe!
Thanks Kelly!
I LOVE a good slow-cooked piece of pork and this recipe sounds fabulous. Droolworthy photos, too 🙂
How could I not respond to a nice comment like that? (Can type a little, but long things take quite a while!)
Please don't worry about responding – just put the energy into healing. Wanted to let you know how darn auspicious this post is. My oven died, completely and finally, just before the blizzard. And last night I took out a Costco pork lump to roast…. well duh! So, I thought I'd have to try the slow cooker – and here in my inbox is this lovely recipe. Can't wait to get the smells going! Thank you for cooking, for being uncanny – everything.
Sandi, thanks! Hope you enjoy.
That looks really really good… especially for a chilly sunday afternoon.
Sunday Roast it is!
Winanne, glad it worked. And I'm counting the days; cast off in about 9 more days!
What a bummer! Thanks for notifying Feedblitz that I wasn't getting your mail;you're back in my inbox every day now. Sending healing energy for a speedy recovery, Winanne

Oh Pam, so glad to hear that. That's really all I'm hoping for with the photos (I'll never be a food stylist!)
Thanks Marlene. So glad you're enjoying the blog.
This sounds like a perfect recipe for the cold weather we are all being hit with. I am a new fan of yours, I dislike wasting too. Keep up the good work.
This photo made me hungry. I can't wait to try this.
Thanks Paula! I guess those hard-to-photograph foods are helping us become better photographers, lol!
Hi Kalyn,
I love those little sirloin roasts–always looking for new ways to prepare them. Thanks for another idea.
Also, I know what you mean about photos that don't do the food justice. Frustrating, isn't it.
Get well soon.
I've been really happy with the pork sirloin tip roasts. They are super lean though; best to use a cooking method that adds some liquid.
This looks so good. Next time I go to Costco I will have to look for the 4 pack of pork sirloin. Looks moist and tender.
You are so sweet! It's frustrating isn't it, because you know if the photo looks bad no one will try the recipe.
So many things that I make don't end up on my blog because of blah photos! BUT, your photos of this roast are mouthwatering, especially that very first one. I love your slow cooker meals!!
Alex, I agree completely!
Loved the recipe. I just think pork sirloin and rosemary are such great friends, aren't they?
