Slow Cooker Pork Tenderloin is such a simple and satisfying meal! The pork comes out tender and juicy after cooking low and slow, soaking up all the flavors you add. It’s a great way to get dinner ready without spending too much time in the kitchen.
I love how easy this recipe is to customize — you can add your favorite herbs, spices, or sauces, and it always turns out delicious. I usually toss in some garlic and a bit of soy sauce or honey for a sweet and tangy touch. The slow cooker does all the work while I’m busy with other things, which makes me appreciate it even more.
My favorite way to serve pork tenderloin is sliced over a bed of mashed potatoes or alongside roasted veggies. It’s perfect comfort food that feels special but isn’t fussy at all. Whenever I make this, I know everyone around the table will be happy and full. It’s definitely a go-to recipe for busy weeknights or relaxed weekend dinners.
Key Ingredients & Substitutions
Pork Tenderloin: This cut is lean and cooks quickly, staying tender in the slow cooker. If you prefer, pork loin works too but may take a bit longer to cook.
Garlic and Herbs: Fresh garlic and herbs like rosemary and thyme give the dish a wonderful aroma. If fresh isn’t available, dried herbs work just fine.
Chicken Broth & Soy Sauce: These add depth and a gentle savory flavor. Low-sodium broth is best to control saltiness. For a gluten-free option, use tamari instead of soy sauce.
Sweetener: Honey or brown sugar balances the savory flavors. Maple syrup or agave can be used instead if you prefer.
Vegetables: Baby potatoes and carrots cook well together in the slow cooker. You can swap for sweet potatoes or parsnips for a different twist.
How Can I Get Juicy, Tender Pork without Overcooking in a Slow Cooker?
Cooking pork tenderloin low and slow is key to keeping it juicy. Follow these tips to nail the timing and texture:
- Start by searing the pork to lock in flavors and get a nice crust. This step is quick but makes a big difference.
- Use your slow cooker’s LOW setting when possible. It gently cooks the meat over several hours, preventing it from drying out.
- Check for doneness with a meat thermometer; pork is safe at 145°F (63°C). Cooking beyond this can make it tough.
- Let the pork rest after cooking. This helps the juices redistribute, making each slice tender and moist.
- Finally, slice against the grain for the most tender bite.
With these simple steps, your slow cooker pork tenderloin will come out perfectly every time!
Equipment You’ll Need
- Slow cooker – This is the main tool, making the cooking hands-free and easy. I like a 6-quart size to fit everything comfortably.
- Skillet – Used to sear the pork, which adds flavor and keeps it juicy. A non-stick or cast iron skillet works well.
- Whisk or spoon – For mixing the sauce ingredients smoothly before pouring into the slow cooker.
- Meat thermometer – To check the pork’s internal temperature and avoid overcooking.
- Serving tongs and knife – For slicing the pork and serving the vegetables and meat easily.
Flavor Variations & Add-Ins
- Swap honey with maple syrup or agave nectar for a different sweet note that pairs well with dairy or grains.
- Add sliced onions or bell peppers with the vegetables for extra color and flavor.
- Use different herbs like sage or oregano to change the aromatic profile.
- Mix in a splash of balsamic vinegar or apple cider to add a tangy kick to the sauce.

How Much Time Will You Need?
This recipe typically takes about 15 minutes to prepare and sear the pork, plus 6-8 hours on low or 3-4 hours on high in the slow cooker. Allow an extra 5 minutes for resting before slicing and serving. Overall, it’s a great hands-off meal that fits easily into your day.
Step-by-Step Instructions:
1. Prepare and Season the Pork:
Pat the pork tenderloin dry with paper towels to remove excess moisture. Sprinkle salt and pepper all over the pork generously for good flavor.
2. Sear the Pork:
Heat the olive oil in a large skillet over medium-high heat. When hot, add the pork and brown it on all sides, about 2 to 3 minutes per side. This step helps lock in juices and adds a lovely crust.
3. Add Vegetables to Slow Cooker:
Place the halved baby potatoes and sliced carrots in an even layer at the bottom of the slow cooker. Nestle the seared pork tenderloin on top of the vegetables.
4. Mix Sauce and Pour:
In a bowl, whisk together minced garlic, chicken broth, soy sauce, honey or brown sugar, Dijon mustard, thyme, rosemary, and parsley. Pour this mixture evenly over the pork and vegetables.
5. Cook Low and Slow:
Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. Cook until the pork is tender and the internal temperature reaches 145°F (63°C).
6. Rest and Finish:
Carefully remove the pork from the slow cooker and let it rest for about 5 minutes. Stir the vegetables and sauce in the slow cooker to coat them well. Slice the pork into thick medallions and place back on top of veggies. Spoon some juices over the top for extra flavor.
7. Serve and Garnish:
Sprinkle fresh chopped parsley over the pork and vegetables, if desired. Serve warm and enjoy a delicious, comforting meal!
Can I Use Frozen Pork Tenderloin in This Recipe?
Yes, but make sure to fully thaw the pork tenderloin in the refrigerator overnight before cooking. Using frozen pork straight from the freezer can lead to uneven cooking and may increase food safety risks.
Can I Prepare This Dish Ahead of Time?
Absolutely! You can prep the garlic, sauce mixture, and vegetables the night before and store them in the fridge. When ready, sear the pork and add everything to the slow cooker to start cooking.
How Should I Store Leftovers?
Keep any leftover pork and vegetables in an airtight container and refrigerate for up to 3 days. Reheat gently in the microwave or on the stovetop with a splash of broth to keep the meat moist.
Can I Add Other Vegetables to the Slow Cooker?
Yes! Feel free to add onions, bell peppers, or parsnips for extra flavor and variety. Just be mindful of cooking times—root veggies work best since they hold up well during slow cooking.
