Pork Loin Roast Recipe Ingredients
This pork loin roast recipe uses simple ingredients that are shelf stable, with the exception of the pork and onion, so it is easy to throw together.
- 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– Adding salty, acidic and umami flavors, this all-purpose sauce is perfect for rounding out the sweet flavors.
- Pineapple chunks in 100% juice– This is part of the Polynesian element. Look for pineapple in 100%juice, opposed to pineapple in syrup.
- Sweet Onion– I prefer a sweet onion in this dish, but feel free to swap it out with a more pungent white onion or red onion.
- Ground Ginger– Since this is a fast recipe and I’m already breaking my “set-it and forget-it” rule by browning, we did opt for ground dry ginger. The ground ginger to fresh ginger ratio is 1/4 teaspoon of ground to every 1 tablespoon of fresh.
- Paprika– To add flavor and color.
- Onion powder– Onion and onion powder, which add remarkable different onion-flavors. Of you are a lover of garlic, feel free to swap this one with garlic powder.
- Coarse Kosher Salt– To elevate natural flavors, although taste test and if using full sodium soy sauce, this might not be needed at all.
- A dash of oil– To prevent sticking and promote browning while searing. This can be any neutral oil with a high smoke point, olive oil, vegetable oil or even a blend can work.
- Cornstarch– For thickening the sauce. Cornstarch adds a velvety texture. Arrowroot can also be used.
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. It also has a nice layer of fat, which helps keep it juicy and adds flavor.
- 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. It is also a lean cut of meat.
Here is a pork tenderloin recipe if you realized that is what you are looking.
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
I tend to shy away from crock pot recipes that require me to brown the meat, I tend to be more of a throw-and-go type of person, but I make an exception for this dish. It is delicious and the extra step of browning makes a marked different in the outcome.
- 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.
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 meat thermometer and check the internal temperature for 145°F.
Instant Pot Pork Loin Recipe Directions
The good new is that you can make this recipe in an instant pot and it also makes one juicy pork loin.
- Sear the meat in IP using the “saute” function.
- Add the other ingredients just like the slow cooker instructions.
- Place the lid on and seal. Cook on high manuel pressure for 15 minutes per pound.
- Use the quick release and continue following instructions for shredding and using the pan juices to make a sauce.
Pork Loin Recipe Slow Cooker Variations
Here are a few tips to get your started and keep you on the right path.
- While you might want to skip the step of browning, for best results 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.
- For a sweeter, sticky sauce, add 2-3 tablespoons of light brown sugar or dark brown sugar.
- If you like a peppery sauce, add a few grinds of fresh black pepper.
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 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.
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 cooked pork loin 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.

It was really good! We ate it the first time with yellow rice and the day after on tostada shells with refried beans, cheese, lettuce and salsa. I’ll make again!
Thank you for coming back to let us know!
Due to the searing and thickening steps, I opted to use my multi-cooker so that I didn’t have to dirty several extra pans.
My pork loin roast was just under 3lbs so, after reading the reviews I decided to cut the cooking time in half. I temped it after 2.5hours on low and it was already in the 180s. I definitely would make sure you check your roast no later than 2.5-3 hours in (depending on size) to make sure it isn’t overdone.
The sauce was reminiscent of teriyaki and when I tasted it after preparing as directed I felt it needed a touch more sweetness so I added a couple of tablespoons of brown sugar and 2 heaping forkfuls of minced garlic just because I love garlic. I also chose to slice my pork thinly instead of shredding it to ensure it was more tender. Thanks for the yummy recipe!
Unfortunately my “slow” cooker is not very slow. My roast was overdone at 3 hours. But we still enjoyed it! I didn’t strain the sauce and used more cornstarch for a thicker consistency. We didn’t find it to be too salty as other reviewers did, and the sauce was plentiful. I served this over rice. The leftovers were great, too.
I’m sorry to hear that, Laurel. I would usually double check that you used a pork loin and not pork tenderloin, but seeing you are a chef, that probably isn’t the case. Love your take on straining the sauce.
Can I use a 2 pack boneless pork loin? If yes cook time and temp please for oven. This looks so good!!
Hi Julie- I haven’t made this in the oven before, but if you are using 2 boneless pork chops, I would go 350°F for about 25-30 minutes. Check the temperature to 145°F.
Have not got a camera but I can assure you your pork with the pineapple turned out really nice I used full amount of all what was in the recipe turned out very tasty will be trying more of your recipes keep them coming Roy…
Thank so much for coming over to tell us this, Roy! We hope you enjoy it time and time again- with or without a camera. 🙂
This has been our family’s go-to for a couple years now. It’s absolutely incredible every time! I recommend adding some jalapeños and sweet thai chili sauce for a little extra kick!
Yay! Thanks for coming back to let us know!
I’m excited to try this recipe. I absolutely love Hawaiian pork. If this is as good as it smells, you just made my family extremely happy.
Woohoo! Let us know how it goes!
I drizzled my pork loin with honey when I put it in the crock pot. Delicious!
That sounds fantastic! Thanks for letting us know.
Should I cook for less time if I’m using boneless country ribs? I couldn’t find a pork loin, only tenderloins, and I’d love to still make this recipe. Thanks!
Yes! I’d reduce about half, I think? Depends on how much they weigh- if you give me the weight, I can give you a better estimate.
Jessica this recipe is a keeper. I made it for dinner tonight and it was a big hit. I made it in the oven
instead of the crockpot. I doubled the sauce because we ate it over mashed potatoes.
Awesome! We love to hear that and thank YOU for coming back to let us know.
Can you tell me what oven temp. you used and how long did you bake it? Thank you.
Hi Shelley, I would start at preheat the oven at 400°F and then reduce the temp to 350 when you put it in- cook for 1 hour (for a 3lb roast). Check the internal temp for 145°F and then let it rest. If it is larger, it will need longer, just use the thermometer!
