Cooking pork loin roast in a crock pot is one of the easiest roasting methods The slow, low heat perfectly tenderizes the meat without any risk of drying it out Follow these simple steps and tips for crock pot pork loin perfection every time.
Choosing the Right Roast
Selecting the right cut of pork is key when slow cooking. Opt for a boneless pork loin roast, ideally 2-3 pounds. This cut comes from the rib area and contains less fat than other cuts. Too much fat can make the pork greasy in the crock pot.
Look for a roast that is evenly shaped and trimmed of excess fat Irregular shaped roasts can lead to uneven cooking The roast should have a nice ratio of lean meat to marbling for best results.
Prep and Seasoning
To maximize flavor, rub the pork loin all over with seasoning before cooking. A spicy dry rub pairs nicely with pork, as do savory herb blends.
Make shallow slits across the top of the roast and rub the seasoning directly into the meat. This helps it penetrate deeply as it cooks, delivering well-seasoned results.
For extra moisture, you can inject a flavorful marinade deep into the center of the roast. Let the seasoned meat rest for 30 minutes before slow cooking.
Determining Cook Time
Cooking time can vary based on the exact size and shape of the pork loin roast, as well as your crock pot model. Here are some general timelines to follow:
-
2-3 lb roast – Low 6-8 hours, High 3-4 hours
-
4-5 lb roast – Low 8-10 hours, High 4-6 hours
-
Boneless loin – Add 30 minutes to times above
-
Bone-in loin – Add 1-2 hours to times above
For best results, cook the pork on lower heat. High heat can cause the exterior to overcook before the inside is finished. Check for doneness a bit before the minimum cook time.
Internal Temperature
The best way to determine if the pork is fully cooked is to check the internal temperature using a meat thermometer.
-
Place the thermometer into the thickest part of the roast, avoiding bone.
-
145°F is the safe minimum temperature for pork.
-
Let rest 10-15 minutes before carving to allow juices to redistribute.
If under 145°F, re-cover and continue cooking, checking every 20-30 minutes until desired temp is reached.
Moisture and Tenderness
One advantage of crock pots is how well they retain moisture in lean meats like pork loin. To guarantee tender, juicy meat:
-
Place roast directly in crock pot, no searing needed. Browning can cause exterior to overcook.
-
Cook on low heat setting only. High can dry out exterior before interior is done.
-
Use a cooking liquid like broth, water, soda or juice. This provides additional moisture.
-
Do not open lid during cooking, escapes steam.
-
Let pork rest before slicing to reabsorb juices.
Flavor Enhancing Tips
To make your crock pot pork extra delicious:
-
Inject marinade deep into the center of the roast.

Coat pork in a flavorful dry rub before cooking.
-
Add herbs, garlic, onions, chili peppers to the crock pot.

Slow Cooker Pork Loin FAQs
The pork loin (or roast) can be cooked on low for eight hours or high for five hours. How long it takes to cook will depend on how big the pork loin is and how hot your slow cooker is.
Pork is cooked when it reaches 145 degrees F. A meat thermometer is the best way to tell if meat is done. That way, we get perfectly cooked meat that is still juicy and not pork that is too cooked!
If you don’t have apple juice, you can use chicken or vegetable broth, cranberry juice, pineapple juice, or even Root Beer to cook your pork loin. Have fun being creative!
If you sear a pork loin before putting it in the crockpot, you can get a nice crust and add flavor. Because life is busy, I don’t always sear the pork first. We love this crockpot pork loin the same way, so I usually skip that step to avoid having to wash a big pan
Absolutely! Leftover cooked pork freezes perfectly and is great in so many meals. You can put it in the slow cooker with barbecue sauce to make Crock Pot Pulled Pork, or you can heat it up and serve it with roasted vegetables and garlic mashed potatoes. See more ideas below!.
What is the difference between pork loin and pork tenderloin?
People have been asking me a lot about how to cook pork loin since my Slow Cooker Pork Tenderloin and Instant Pot Pork Tenderloin recipes were so well received.
Many people think they can be used together, but they can’t be. That’s why I wanted to share my pork loin recipe with you on The Recipe Rebel as well—it’s one of our favorites so why not?
A pork tenderloin is much smaller than pork loin, it usually weights around 1-1. 5 lbs, whereas the pork loin I used for this recipe was 5 lbs. You can see why the recipes can’t be switched around: pork loin needs a lot more seasoning and a lot longer to cook.
