Pork loin is one of our favorite inexpensive meals. You can cook pork loin on the grill, roast it in the oven, or throw it in a slow cooker. This Slow Cooker Pork Loin Roast is covered with seasonings, pan-seared, and then slow-cooked for a tender and juicy result. This recipe works well with pork loin roast or pork shoulder roast. Do not substitute pork tenderloin for this recipe, as that is a different, smaller cut of pork.
The cooking time will vary depending on the cut of meat you use. Pork loin roast is a lean cut of meat without a lot of fat, so it cooks fairly fast, 4-5 hours on low or 2-3 hours on high. You can use a meat thermometer that can stay in your crockpot with the lid on to ensure it doesn’t overcook. A pork shoulder roast is a tougher, fattier cut of meat, so it requires a longer cooking time. To get fall-apart tender and break down the tissues and fat, it will need to cook on low for 10-12 hours or on high for 6-8 hours.
Browning the pork roast before placing it in the slow cooker adds extra flavor by locking in the juices and caramelizing the natural sugars in it. If you’re short on time, you can skip browning the pork and simply season it and add it straight to the slow cooker. I do think it’s worth the extra effort to brown it first.
This recipe is made with pretty common ingredients, but not everyone has molasses in their cupboards. Some good substitutes for molasses include dark corn syrup, honey, maple syrup, or just some extra brown sugar. If you don’t have balsamic vinegar, you can substitute it with apple cider vinegar. I like to deglaze the skillet by adding all of the sauce ingredients to the pan and simmering for a couple of minutes. If you choose not to brown the pork first, you can also skip the deglazing step. Simply whisk the sauce ingredients together in a small bowl and pour over the top of the pork loin in the slow cooker.
You can serve this pork loin sliced or shredded. A pork loin roast should be cooked to an internal temperature of at least 145° F for slicing or 160° F for shredding. A pork shoulder roast should be cooked to at least 165° F to be sliced or 190° F to be shredded. Allow the meat to rest for 5-10 minutes before carving.
I served it shredded on top of rice. It would be great with mashed potatoes, mashed or riced cauliflower, sweet potatoes, or your favorite sides.
To thicken the sauce to be used as a gravy, you can do so by pouring the sauce from the crockpot into a saucepan and adding cornstarch mixed with a little cool water. Add 1 tablespoon of cornstarch slurry at a time, simmer, and whisk until you reach your desired thickness.
