Pork loin has a reputation: “dry.” (Rude, honestly.) But toss it in the slow cooker the right way and you get juicy, tender Hawaiian pork with pineapple-soy glaze vibes—perfect over rice, stuffed into sandwiches, or shredded for tacos.
I’m giving you sliceable OR shreddable cook times, plus the simple trick that keeps pork loin from turning into edible cardboard.
What You’ll Need
This Hawaiian pulled pork recipe uses simple ingredients that are shelf stable, with the exception of the pork and onion, so it is easy to throw together. A full list of ingredients with measurements for this recipe is available in the printable recipe card below.
- Pork Loin– Pork loin is a cut of meat from the back of a pig, located just below the shoulder and above the tenderloin. It’s a lean and tender cut that’s commonly used for roasts, chops, and other pork dishes.
- Low-sodium soy sauce
- Pineapple chunks in 10% juice
- Sweet onion
- Ground ginger
- Paprika
- Onion powder
- Coarse Kosher salt
- Dash of oil
- Cornstarch
Pork Loin vs Pork Tenderloin
Grab the right cut: Pork loin and pork tenderloin are not interchangeable. Pork loin is a larger, wider roast (often labeled boneless pork loin roast, top loin, or center loin) that does best with low, slow cooking and often has a little fat to keep it juicy. Pork tenderloin is a long, skinny ~1-pound cut meant for quick, high-heat cooking-it will overcook and dry out in this recipe, so don’t swap it in.
How to Make Pork Loin in a Crock Pot (Step-by-Step)
I do prefer to make a pork loin in the slow cooker because it is essentially a tabletop braiser, allowing the steam and liquid to concentrate instead of evaporate. It is perfect for leaner cuts of meat that require a low and slow temp for optimal juiciness. You can make it in the oven as a traditional braise.
- Seasoning & Dry Pork. Make the spice rub and dab the pork loin dry with paper towels. Rub the pork liberally with the spices.
- Sear. Heat oil in a large skillet over medium high heat. Sear the pork in the hot pan until browned on each side, beginning the the fat side down for 3 to 4 minutes on each side.
- Make Gravy. Meanwhile, dice the onion and make the sauce for the slow cooker.
- Pineapple Base. Place half the pineapple chunks on the bottom of your slow cooker then place your seared pork loin on top of them with the fat side up. Add the remaining pineapple, diced onion, and pour the gravy mixture over the top.
- Shreddable: Cover and cook on high for 4-5 hours. The pork should shred easily with a fork and register at 145°F.
Sliceable: Cover and cook on high for 3-4 hours. The pork should register at 145°F. Thinly slice using a sharp knife.
Remove the meat from the slow cooker and allow the pork to rest before slicing or shredding while you make the sauce.
- Make Gravy. Strain the liquid from the slow cooker through a sieve into a medium saucepan over medium high heat and bring to a simmer. Reserve the pineapple chunks from the slow cooker for serving. Whisk the cornstarch with 1 ½ tablespoons cold water to make a slurry then slowly whisk it into the simmering sauce. Continue to stir gently until thickened.
- Serve. Serve the pork with the sauce and reserved pineapple chunks and chopped scallions.
How to Keep Crock Pot Pork Loin Juicy (Chef Tips)
Pick the right cut: boneless pork loin roast, not tenderloin- no they aren’t the same!
Sear = flavor. It’s not required, but it builds a better crust and deeper flavor (hello Maillard reaction).
Don’t drown it. Liquid should come up about ¼ of the way- pork releases moisture as it cooks and you don’t want it to be too saucy.
Fat side up: if yours has a fat cap, let it baste the roast while it cooks. Sure, you can trim this, but I like the flavor and it helps keep the roast juicy.
Use a thermometer (because guessing is stressful):
Sliceable: cook at a higher temp so the fibers are tight, pull around 140–145°F, rest 10–15 minutes.
Shreddable: you’re going for “fork collapses it” tenderness, use a the low and slow method to soften connective tissues and loosen fibers. Still pull right at 145°F.
Thicken the sauce: cornstarch slurry at the end so it clings to the pork and is glossy.
Variation Options
This is such a good base recipe, but here are a few ways to put your own twist on it.
- Sweeter– Some like a true sweet Hawaiian sauce, so think about adding 1-2 tablespoons of light brown sugar, 1 tablespoon of honey or using pineapple tidbits in heavy syrup. Do not do all 3- just pick one!
- Spicy– Love a sweet and spicy pairing? Me too! Add 1/2-1 teaspoon crushed red pepper flakes or 1-2 teaspoons of Sriracha to the sauce. Also feel free to use a chile crisp oil on the side for serving.
- Garlic & Ginger– Add 2-4 minced or grated garlic cloves or 1 tablespoon grated ginger to the sauce. These play well together so you can add both.
- Add Veggies– I typically like my veggies on the side, but feel free to throw some in the crock pot for a truly one-dish meal. Raw chopped bell peppers, carrots and snap peas all work well and won’t totally disintegrate when added.
Perfect Pairings
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 is also great over mashed potatoes or roasted sweet potatoes. 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.
Storage and Freezing
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.
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.
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 300°F oven for 3-4 hours, or until you can shred it easily with a fork.
Yes, but having enough liquid, leaving the fat cap on and timing will prevent this from happening.
No, the liquid will be about a quarter of the way up- see step-by-step photos for a visual cue.
You can, but will then to buy pineapple juice. Fresh pineapple is also a but more acidic and not as sweet, so think about adding 1-2 tablespoons of brown sugar to balance out the sauce.

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!
This recipe is now one of my favorites! Made this yesterday and my husband & I loved it. The pork just fell apart and the pineapple sauce was delicious poured over the pork & Jasmine Rice I served it over! Fortunately I have enough loin left over for dinner tonight. So glad I came across Savory Experiments while searching for new pork recipes.
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.
