You will love this Hawaiian Pork Loin Slow Cooker recipe!
Pork loin is a staple standby in our house. Often sold in 2 to 5 pound roasts, it’s an easy way to feed a group or to cook once and have leftovers to reimagine for days. This Hawaiian pork loin version ticks all of those boxes and is packed with big flavor.
With very simple ingredients I can rub the loin down with a homemade spice mix, give it a quick sear, then toss it in my slow cooker for a few hours while I go about my day.
A pot of rice later, some Hawaiian rolls, and a few minutes to whip up a sauce from the slow cooker juices, and dinner is on the table. Everyone is happy, myself included!
Crock Pot Pork Loin ingredients

PRO TIP: Maui or Vidalia onions are my go to sweet onion varieties for this recipe, but any sweet onion you can find will do. In a pinch, substitute red onion with ½ a tablespoon of honey.
Pork Loin vs Pork Tenderloin
If there’s one thing to remember it’s to make sure you’re picking up the right cut. Pork loin is not to be confused with pork tenderloin!
- Pork Loin – A lean, large, wide cut of meat that is broken down into many different cuts, like chops and roasts. You want a boneless pork loin roast for this recipe. It may be sold as a top loin or center loin roast and it benefits from low, long cooks.
- Pork Tenderloin – Similarly named but NOT a similar cut in any other way. Tenderloin is a thin, narrow cut that averages about 1 pound and is considered one of the most tender cuts of pork available. It’s best cooked quickly at high heat, and cannot be substituted in this recipe.
PRO TIP: Choose a pork loin with a nice white fat cap on it. A lean cut like pork loin benefits from the extra fat to stay moist and tender.
How to make this Pork Loin Crock Pot Recipe
- Heat a tablespoon of oil in a large skillet over medium high heat. While your pan is heating, combine your onion powder, paprika, salt, and pepper in a small bowl.
- Pat your pork loin dry and rub down with the spice mixture. When your pan is hot, sear the loin on all sides, beginning with the fat side down, until the outside is caramelized and browned, about 3 to 4 minutes per side.
- While the pork is searing, dice your onion. Open your pineapple and pour off the juice into a separate bowl with the soy sauce.
- Place half the chunks of pineapple in the bottom of your slow cooker then place the seared pork loin on top, fat side up. Add in the remaining pineapple, the diced onion, and pour over the pineapple juice and soy sauce mixture. Cover and cook on low for 5 hours.
- When your pork is done, remove from the slow cooker and set aside. Ladle the liquid through a sieve into a saucepan set over medium high heat and bring it to a simmer. Reserve some of the pineapple chunks for serving.
- Whisk the cornstarch with 1 ½ tablespoons of cold water to make a slurry. When sauce is simmering, slowly whisk the slurry in and continue stirring gently until thickened.
- Shred the pork and serve with the reserved pineapple chunks and a generous drizzle of sauce.
PRO TIP: Use a food processor to chop the onion uniformly and quickly!
How long does it take for pork to cook in slow cooker?
The cook time is highly dependent on the size of roast. Here is a quick guide for your size of roast:
- 3-4 pounds: 5-6 hours on low, 3-4 hours on high
- 4-6 pounds: 6-8 hours on low, 4-5 hours on high
To be sure your roast is complete, use a digital thermometer and check the internal temperature for 145°F.
Are you drooling yet? While it’s not quite ‘dump and go’, this easy slow cooker pork loin is a family favorite. Keep a couple cans of pineapple chunks in the cupboard and you can whip it up anytime!
Taking that 5 minutes to make the sauce really makes all the difference, it drives home that sweet Hawaiian flavor!
Pork Loin Recipe Slow Cooker Tips
While you might want to skip the step of browning, this adds loads of flavor to the meat and the sauce and kick starts the cooking process. You can throw it in unbrowned, but expect the sauce to be a little less seasoned and add 15-20 minutes to the cook time.
Changing the type of onion used will change the flavor profile of the sauce. A sweet onion gives sweeter results while a yellow or red onion will be more oniony.
If you really like pineapple, consider doubling the amount of pineapple.
Make sure you are using a pork loin, not a pork tenderloin, which is smaller in diameter and leaner. You can use the sauce recipe for a tenderloin, but the cooking time is different.
How to serve this Slow Cook Pork Loin recipe
This slow cooker pork loin is easiest served over a bed of white rice, but you can also use toasted couscous or ranch rice.
It also make an amazing pulled pork sandwich.
As a side, consider serving with vegetables like marinated green beans, roasted rainbow carrots, or whole roasted cauliflower.
Shredded meat can be used in tacos or even quesadillas and nachos! Leftovers can be served on top of a fun leafy green salad too.
Pork Loin Recipe Slow Cooker Storage
Store leftovers in an airtight container in the refrigerator for up to 5 days. Use in another recipe that calls for pulled pork or reheat the meat only in the microwave.
Can this be frozen?
Absolutely. Prepare the Hawaiian pork loin as directed, then shred and freeze in desired portions. I recommend making the sauce and freezing it in an ice cube tray, then adding cubes to the bags or containers of shredded pork.
Pork Loin Roast Slow Cooker FAQs
Technically yes. Your pork loin will cook fine without searing it first. However searing the spice rubbed pork first wakes up the aromatic nature of the spices (big flavor), and creates a crust.
That crust creates a beautiful texture when you shred the pork, a lovely combination of crunchy browned edges and tender shredded meat.
No, it’s certainly not necessary if you’re comfortable with your sauce having chunks of onions in it. However, straining it leaves you with a silky drizzly sauce I highly recommend.
Absolutely! This recipe will work with either pork butt (pork shoulder) or boneless pork country ribs.
Yes! Simply start your recipe by searing the pork in a large dutch oven or oven safe pot. Then add in the pineapple, onion, and the pineapple juice/soy sauce mixture.
Cover and place in a 325°F oven for 2 to 3 hours, or until you can shred it easily with a fork.
Since this recipe includes an adequate amount of liquid and the slow cooker lid should be keeping all condensation in, the only reasons your pork could be dry are that you used a pork tenderloin (instead of loin) or it was cooked too long for the size. However, this is a hard cut of meat to over cook!
Browning meat before placing it in the crockpot isn’t essential, but does add sophistication and flavor to the meat and the sauce.
There are many cuts of meat that get more juicy and tender when cooked low and slow. It helps to tenderize and break down connective tissues that otherwise can feel chewy or tough. But there is a tipping point at which the meat starts to dry out, so wait until it reaches 140°-145°F and then remove it.
Yes! If the slow cooker and roast don’t have any liquids, then the roast will be dry, tough, and flavorless. The slow cooker is essentially a table top braiser and braising requires liquid to create steam and condensation, making the roast stay moist.
For this roast, low is best because it gives those connective tissues longer to break down, but high is still an option and works well. It is a good middle ground between a true low and slow cook and high heat roasting.
You can put raw pork in a slow cooker and even though this roast will be browned on the exterior, the interior will still be raw.

Absolutely loved this recipe! Definitely take the few minutes to brown up your roast, it seals that moisture in. The only thing we were a bit disappointed in was we could have easily doubled the “gravy” part of the recipe. This ones a keeper in our house. Thanks!!
Thank you for the feedback! I like the sauce too- I love it over rice!
Thanks for the recipe. Loved it.
Glad you enjoyed!
Sent me any “Pork “ recipes
Tried this yesterday. Unfortunately, my “slow cooker” cooked this 4 pound loin way too fast and when I checked on it at 4 hours, it was already at 160!!😭. I had it set to the low setting, not sure why it cooked it so far. We still are this dried, though meat and the only saving grace was the sauce which we drowned each bite in… I’ll definitely give this another try tho…
Wow! Id say that is fast, low setting is usually only about 200 degrees. I’m glad the sauce saved the day!
Delicious pork! Easy as well!
Thank you, Debbie!
Flavor is really good but I think next time, I’ll use pork shoulder. The loin just gets so dried out in the slow cooker. Sauce is delicious though!
Thanks for the feedback- this would be amazing with a pork shoulder too.
Not a big pork fan but husband loves it, so always looking for pork recipes that I can tolerate. This was really good. I really enjoyed it and husband said we can “add it to the rotation” – so he liked it too!
Yay! Well, that is a WIN in my book!
We made this for dinner tonight and it was AMAZING! I love the flavors of pineapple and pork together 😊 I ended up using twice the amount of cornstarch/water and our sauce never thickened, but we did spoon it on top of the wild rice we made to eat with this meal and it was delicious. Thanks for the recipe!
Yay! That is what we love to hear!
Can you make this in an instant pot?
You could. Still brown it, then manual high pressure for 25 minutes. Allow natural release for 10 minutes, then quick release. You might need to cut the roast into two pieces to get it to fit into a standard 6 quart IP.
Can I add a little brown sugar instead of onion or honey?
Hi Nancy, brown sugar can replace the honey, but not much will replace the onion. You can leave it out if you are opposed to onion.
loved it. but im guessing i used the wrong soy sauce as mine was too salty. so i added brown sugar as was suggested in one of your reviews and it helped alot. will make again. thanks.
Hi Karrie- the soy can make all the difference. Knowing your particular brand is key. I like using dark mushroom flavored- even though it isn’t “light”, it is actually less salty.
Made this according to the oven directions. After 2.5hrs the liquid had almost all comes out. There wasn’t enough liquid to start. I will make this recipe again using the slow cooker to compare. I did end up making a separate Hawaiian sauce to put on top.
Thanks for the feedback, Rebecca, we will look into this!
Made this for dinner tonight, so yummy! Everyone loved it. My son said it was good without the sauce and even better with it
Woohoo! Thank you for coming back to let us know~
Really enjoyed this… added red and green pepper, a jalepeno, and some fresh ginger to the slow cooker, and it was amazing.
Love the additions! Thanks for coming back to let us know!
This was so good, and obviously, so EASY.. hello Crock-pot. i tweaked this recipe at the end. When everything was all done, i went ahead and added about 1/4 cup of brown sugar. For me, and my hubs, this was a little too salty (even with the low sodium soy). Adding the brown sugar heighten this dish.
Thank you for taking the time to come back and leave us this note and also the feedback for others readers!
This was very easy to make, but the flavor was just ok. I followed the instructions exactly and I feel that it was way too salty. Even the pineapples lost its sweetness and tanginess from cooking in the sauce.
Hi Lily, I am really sorry to hear that! Did you use regular soy sauce or lite? Different brands can vary greatly in salt content and so can people’s taste for salt. I’ll add that in the notes so others have a heads up!
Oh, girl, I like your style! Pork and Pineapple is such a glorious combo! Can’t wait to dig into this sweet and savory deliciousness.
I loved your tip about chopping the onions in a food processor, quick and easy! This recipe was wonderful and made great leftovers!!
This pork loin looks so amazing! I love the hawaiian twist on this, it sounds so delicious and I know my family will LOVE this recipe!
I’ve always loved pork loins for their lean, healthy qualities, but also for how tender and delicious they are. This recipe sounds like a winner and I love that you make it in the slow cooker — plus pineapple has always been a weakness for me.
