Imagine coming home to the irresistible aroma of savory pork simmering in your crock pot. Our recipe promises just that—a mouthwatering dish that practically cooks itself. Whether you’re a seasoned chef or a kitchen newbie, this fuss-free meal will have you feeling like a culinary pro in no time.

Ingredients

Pork Loin Roast: This recipe calls for a 3-4 pound pork loin. You’ll want to remove the excess fat from the loin. Do this by piercing your knife into the fat or silver skin and running your knife along the loin. **Frugal tip: Pork is an incredibly affordable protein compared to beef. In the midwest, you can find pork loin roasts on sale for less than $3 per pound.

Onions and Garlic: Both of these provide aromatics for our sauce, but the onions serve a second purpose. Sliced in rounds, these will go in the bottom of the slow cooker to keep the loin up off the bottom.

Brown Sugar: Brown sugar is going to add sweetness to our sauce and also almost caramelize on the top of our roast, creating a delicious glaze.

Balsamic Vinegar: Balsamic vinegar has a richer flavor than other vinegars. It provides balance to the sauce without being overly tart. If you don’t have balsamic vinegar, you could use red wine vinegar or apple cider vinegar.

Soy Sauce: Everyone has heard of umami, but no one really knows what it is. It is a savory taste that really punches up meat dishes. Yes, soy sauce also provides salty flavor which we need in our sauce, but it also deepens the flavor of the whole dish. Feel free to use low-sodium soy sauce if you like.

Equipment

How to Make Slow Cooker Pork Loin

  1. Sear the pork loin: Heat olive oil in a large skillet over medium-high heat. Season the pork loin with salt and pepper, then sear it on all sides until golden brown.
  2. Mix the marinade: In a small bowl, combine balsamic vinegar, brown sugar, soy sauce, and minced garlic.
  3. Slow cook: Layer your sliced onions in the bottom of the crock pot. Transfer the seared pork loin to your slow cooker and pour the sauce over it. Cover and cook on low for 5 hours or until the pork reaches an internal temperature of 145°F.
  4. Thicken the sauce: Once your pork loin is cooked, remove it and allow to rest while you thicken the sauce.  Pour the onions, sauce and any drippings from the slow cooker into a saucepan and heat over medium heat until the sauce thickens a bit, about 5 minutes depending on how thin or thick you like your sauce to be.
  5. Serve and enjoy: Once the pork is rested, slice it against the grain and serve with a drizzle of the flavorful sauce.

Variations

  • Swap out balsamic vinegar for apple cider vinegar for a tangy twist.
  • Experiment with different types of sweeteners like honey or maple syrup instead of brown sugar.
  • Add sliced bell peppers or mushrooms to the slow cooker for extra flavor and texture.

Tips

  • For optimal flavor, sear the pork loin before slow cooking to lock in juices and create a delicious caramelized crust.
  • Use a meat thermometer to ensure your pork reaches the recommended internal temperature of 145°F for safe consumption.
  • Don’t overcrowd the slow cooker—make sure there’s enough space around the pork loin for even cooking.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days or frozen for longer storage. I love to dice up leftover pork loin and use it in stir-frys. Swap the ham in this Teriyaki stir-fry recipe for pork and you’ll have a tasty treat!

Frequently asked questions

What’s the difference between Pork Loin and Tenderloin? Both cuts are very lean and run along the back of the pig. Loin is larger in diameter and usually comes with a thin layer of fat. The tenderloin is much smaller and is more tender. It is best for the tenderloin to be cooked on high heat very quickly.

Can you freeze this recipe? Yes, simply allow the cooked pork loin to cool completely, then store it in an airtight container or freezer-safe bag for up to 3 months. Thaw in the refrigerator before reheating.

Can you make this crock pot pork loin recipe ahead? Absolutely! Prepare the marinade and sear the pork loin the night before, then refrigerate both until ready to cook. In the morning, simply transfer everything to the slow cooker and let it work its magic.

How to store cooked pork loin? Store leftover pork loin in the refrigerator in an airtight container for up to 3-4 days, or freeze for up to 3 months for longer storage.

Can I use a different cut of pork? While this recipe is tailored for pork loin roast, you can experiment with other cuts like pork tenderloin or pork shoulder. Adjust cooking times accordingly for best results and cook to an internal temperature of 145°F.

With minimal prep and maximum flavor, this Slow Cooker Pork Loin is a game-changer for busy weeknights or leisurely weekends. Balsamic vinegar and brown sugar create the most luxurious sauce to go with the pork!

Prep Time 10 minutes
Cook Time 5 hours
Additional Time 10 minutes
Total Time 5 hours 20 minutes

Ingredients

  • 1 Tablespoon oil
  • 1 (3-4 pound) pork loin, excess fat removed
  • salt and pepper
  • 1 large onion, sliced in thin rounds
  • 4 cloves garlic, chopped
  • 1/2 cup brown sugar, lightly packed
  • 1/2 cup water
  • 1/2 cup balsamic vinegar
  • 2 Tablespoons soy sauce

Instructions

  1. Season all sides of pork loin roast generously with salt and pepper.
  2. Place cut onions in the bottom of your slow cooker.
  3. Heat a large skillet over medium-high heat. Add oil and sear pork loin on all sides until golden brown, 2 minutes per side. Remove from pan and place on top of onions in slow cooker.
  4. Turn off the heat on your skillet and add garlic, water, balsamic vinegar and soy sauce. Stir together ingredients, making sure to scrape up any brown bits that stuck to the pan.
  5. Sprinkle brown sugar on top of pork loin and then pour sauce mixture over the pork.
  6. Cover and cook on Low for 5-6 hours, or until the internal temperature is 145 degrees Fahrenheit.
  7. Once cooked, remove pork loin to a plate and cover with foil. Allow to rest for 10 minutes.
  8. While pork is resting, pour the sauce and juices from the slow cooker into a saucepan. Bring to a simmer over medium heat and allow the sauce to thicken, 5-6 minutes. Stir occasionally.
  9. Slice your pork loin against the grain to ensure maximum tenderness.

Notes

Feel free to double the water, brown sugar, vinegar and soy sauce if you'd like lots of sauce.

The pork loin is done cooking when the internal temperature reaches 145 degrees Fahrenheit. Since it is a lean cut, it will not fall apart and you will be able to slice it. **Depending on how hot your slow cooker runs, your pork loin may reach 145 degrees Fahrenheit quicker than 5 hours.**

This recipe also works with pork shoulder. Cook 3-4 lb pork shoulder on Low for 9-10 hours. It will be fall-apart tender.

Leftovers will keep in the fridge for up to 3 days or frozen for up to 3 months.

  3. Made this tonight. It was delicious! I’ve tried so many pork recipes for the slow cooker and this was by far the best! Thank you.

  4. This was so delicious. The tenderloin came out tender and not dry at all, which can be a problem with the tenderloin. The sauce was amazing! I added fresh mushrooms which went perfectly. One of my favorite online receipts and I will be making again.

  6. Hi All,
    I plan to make this with vegetables (red potatoes and carrots). My question is: when do I add the vegetables to the slow cooker? Should I halve the potatoes first? Any suggestions greatly appreciated.

    Thank you

  9. Have a 3# in my crock now. Followed recipe to the letter, but will be checking temp early since her recipe calls for larger cut. Already smells delish!… F the haters who are too ignorant to follow simple directions.

    • Hi, Toni. Tenderloin is better suited for quick cooking because it is so small. You can absolutely use these same flavors for the sauce and sear your tenderloin in a skillet and finish in a 350 degree oven until it reaches internal temperature of 145 degrees F. Should take less than 30 minutes.

  10. Made this last night and it was extremely tasty! I added mushrooms to it and it was great. Next time I make it, I’ll double the sauce recipe though, definitely not enough – it was a bit dry. Other than that, thought it was great.

    • Cooked a 4.25 lb pork loin roast in my 5 Qt slow cooker, for 5 hours 30 minutes on Low setting, but checking it frequently. I let the pork loin rest for 30 minutes and it was easy to cut. Reserved the remaining liquids, added flour to thicken it into a delicious gravy. I’m planning on sharing this tomorrow evening. Fellow diners are to bring an appetite, compliments and Tupperware for another meal during the week. Your Recipe was simple to make and enjoy.
      Thank you!

  11. Wow this was great! I had a tiny 1.75 lb center cut loin roast. I usually just follow a slow cooker recipe by the time but this time after 2 hours I checked the temp. Took it out at about 150 degrees and it was perfect. Never had such a tasty pork loin. Love the sauce. Dogs and husband were lined up waiting for a sample. Thumbs/paws up! Thank you!

  12. Hi Sarah, THANK YOU for sharing this recipe! Made it today & my family really enjoyed it! It was so flavorful (actually, the one comment that was repeated throughout dinner was, “this is SO tasty!”) & the sauce was great & so easy to put together! I’ll definitely make this again!

  13. Trying this tonight.. using a true Pork Loin 3 1/2 inches thick and 4 inches wide, 6 inches long. Not a skinny tenderloin that is 4 lbs. I am sure mine will cook 5 or more hours on low. Very excited to try it it, because pork loin is a boring piece of meat. lol. Thank you for the recipe.

  14. Unfortunately, this recipe fell flat for us. While I cooked it on low for an hour less than called for, the pork was extremely dry. Additionally, the sauce was very sweet and unappetizing. No one in my family enjoyed it. After we all tasted it, it went right into the garbage.

    • Ditto…not a fan at all. My husband will usually eat something even if he is not a fan but this is not one of them…just hate that I wasted all that good meat (but you don’t know unless you try). Thank you for taking the time to post all your recipes!!!
