Ingredients
The ingredients may seem like a lot, but they’re basic, and you likely already have them in your pantry:
For the slow cooker liquid
This is the liquid your pork steeps in and sucks up while cooking:
- Chicken broth: Choose a low-sodiumchicken broth to control the dish’s saltiness. If preferred, you can also use vegetable broth as a substitute.
- Soy Use regular or low-sodium soy sauce according to your taste preference. Tamari can be used as a gluten-free alternative.
- Onion: You can use any variety of onion based on your preference, such as yellow, white, or red.
For the pork
Tender pork loins get prepped with a rub before cooking for added flavor. Here’s what you’ll need:
- Pork loin: Ensure the pork loin fits comfortably in your slow cooker. If it’s too large, you may need to cut it in half lengthwise. Look for a well-marbled pork loin for juicier results.
- Kosher salt and black pepper
- Garlic and onion powder
- Avocado oil
For the sauce
These 4-ingredients are what make up this sensational sauce:
- Balsamic vinegar
- Honey
- Garlic
- Butter: Adds richness and a glossy, velvety texture to the sauce.
Substitutions and Variations
Here are a few twists and turns you can take with this recipe:
- Substitute pork loin: If pork loin is unavailable, you can use pork tenderloin in the same quantity by weight. If you’d like to use pork shoulder, use my Slow Cooker Pork Shoulder recipe instead.

Tools to Grab
Here’s what to get ready to make this dish:
- Slow cooker: Whip out your crock-pot or whatever brand of slow cooker you own.

How to Make Tender Slow Cooker Pork Loin: An Easy Guide
This is a simple recipe. Here’s how to make it:
1. Prepare slow cooker cooking liquid
Start by adding the chicken broth, sliced onion, and soy sauce. Give it all a stir.
2. Prepare
Make a rub by combining the following: salt, pepper, garlic powder, and onion powder. Rub this mixture all over the pork loin.
3. Sear the pork (optional)
Place a large skillet on medium-high heat, then add oil. Once the oil is shimmering hot, sear the pork loin. Cook them on all sides until they are golden brown all over. This takes about 3 minutes per side.
4. Assemble + cook
Whisk the balsamic vinegar, honey, and garlic in a small bowl.
Place the pork loin on top (fat-side up) and brush it with the balsamic vinegar liquid.
Cook the pork for 6-8 hours on low or 3-4 hours on high. You’ll know the pork is done because it will be fall-apart tender.
5. Finish off the sauce
Whisk butter into the sauce.
Taste the sauce and add a bit more salt and pepper if needed. I find mine usually needs a pinch more of both.

Make Ahead and Storage
Want to get this going in advance and store the leftovers to enjoy them for a few days? Here’s how:
Make Ahead
You can easily make this slow cooker pork loin recipe ahead of time.
Simply prepare the pork loin according to my instructions, including seasoning and searing it, then place it in the slow cooker with the liquid ingredients. Instead of cooking immediately, cover the slow cooker insert and refrigerate it overnight.
In the morning, place the insert back into the slow cooker, set it to the desired cooking time, and let it cook as usual.
This allows you to have a delicious meal ready with minimal effort when you’re ready to eat.
Storage
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm the pork loin slices in the microwave or oven until heated.
The sauce may thicken in the refrigerator, so you can thin it out with a splash of chicken broth or water when reheating.
Alternatively, freeze any leftover pork loin slices in a freezer-safe container for 2-3 months.
Thaw overnight in the refrigerator before reheating. Enjoy the tender and flavorful slow cooker pork loin whenever you need a quick and satisfying meal.
How to Serve this Tender Slow Cooker Pork Loin Recipe
Load up a plate with a soft, creamiest mashed potato and a side of pan-fried asparagus with your slow cooker pork tenderloin. I love this recipe with any green veggies.
A sneaky side of air fryer eggplant is delicious, too, and adds a little texture.

Final Notes, Pro Tips + Science-Based Secrets
As a food scientist, here are my pro tips and notes to remember when making your slow cooker pork loin.
- Use a meat thermometer to ensure the pork loin reaches the internal temperature of 145°F (63°C) for safe doneness.
- Slow cooking breaks down collagen in the meat, converting it into gelatin, which makes pork loin fall-apart tender. (Related: Slow Cooker vs. Pressure Cooker)
- The Maillard reaction, which occurs during searing, creates complex flavor compounds and enhances the overall taste of the dish. Skip the searing step only if you’re super short on time!
- Resting the cooked pork loin allows the muscle fibers to relax and reabsorb moisture, ensuring a succulent and flavorful end product.
- Keep the lid closed. The closed lid traps steam and moisture, creating a humid environment that helps keep the meat juicy.
- Avoid overcooking. Overcooking causes muscle fibers to denature, squeezing out moisture and causing dryness. The low temperature of the slow cooker ensures a gentle cooking process, reducing the risk of overcooking.

FAQs About Slow Cooked Pork Loin
Just skimming through this article? Here are some key take-aways:
Cooking times can vary depending on the size of the pork loin and the temperature setting of your slow cooker. Generally, pork loin takes about 6-8 hours on low heat or 2-3 hours on high heat in a slow cooker. Use a meat thermometer to make sure the pork loin reaches an internal temperature of 145°F (63°C) for safe consumption.
No, I don’t recommend cooking a frozen pork loin directly in a slow cooker, as it can lead to uneven cooking and potential food safety issues. It’s best to thaw the pork loin completely in the refrigerator before cooking to ensure even cooking and optimal results.
While pork loin is a relatively lean cut of meat, it may have some extra fat that you can trim if you like. Trimming excess fat can help prevent the sauce from becoming greasy and reduce the overall fat content of the dish. However, leaving some fat on the pork loin can add flavor and moisture during cooking.
Yes, you can add vegetables such as carrots, potatoes, onions, and celery to the slow cooker along with the pork loin to create a complete meal. Be sure to cut the vegetables into uniform pieces and place them at the bottom of the slow cooker.

This was awesome!!! I made the recipe exactly as explained…oh my goodness, SO good!! Thank you!
A great and amazing recipe
This recipe has easily become a favorite in my household. I have made it including the optional searing stage and think that really takes it over the top, but in a pinch, skipping that step stills creates a delicious meal. Today, I tried it with a pork tenderloin and it came out just as delicious!
Excellent recipe. The pork was extremely moist and that sauce? oh my! Thank you so much.
Hands down the best pork tenderloin recipe! I made sauerkraut on the stovetop with carmelized onions and used a little of this pork tenderloin liquid to finish the onions and sauerkraut. Absolutely amazing! The only change to the liquid I did was count aminos for the soy sauce to make It gluten free. Ty for this! We couldn’t stop eating It!
For maximum flavor how far ahead should one prep the pork loin ?
Honestly with the slow cooker you don’t have to prep in advance for amazing flavor. It cooks for so long in a closed environment that it is very flavorful made all in one go. You could season the pork 1-2 days in advance, though, if you like!
Can you do sauerkraut with the recipe?
It’s a winning recipe in my house! All of my children absolutely loved this! Thanks so much for sharing this recipe!
Very tasty! I didn’t sear it. I didn’t have balsamic vinegar so I subbed red wine vinegar and sugar that I googled. So yummy!
This turned out exceptionally good. The meat was tender and the sauce was 10/10.
When I finished the pork loin, I strained the liquid and added some sugar to cut the vinegar. Reduced the liquid after adding the butter. This was better for me and family. Loin was very tender and tasty. Good recipe!
