Ingredients for amazing pork tenderloin slow cooker recipe with potatoes and
Herb-infused pork tenderloin and fluffy potatoes—just dump, season, and let magic happen.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut for best tenderness |
| Baby Potatoes 🥔 | 2 lb | Halved, unpeeled for texture |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For marinade and potatoes |
| Garlic Cloves 🧄 | 4 cloves | Minced for marinade |
| Fresh Rosemary 🌿 | ½ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tenderizing pork |
| Dried Parsley 🌿 | 1 tsp | For garnish, optional |

| Butter 🧈 | 2 tbsp | Unsalted, for potatoes |
The pork tenderloin is your star here. Costco or Whole Foods usually carry the best center-cut pieces—look for ones that are firm and have good marbling. If you can't find center-cut, a regular tenderloin works, but trim off any silver skin for tender results. The baby potatoes? Trader Joe's or Aldi sell them pre-washed and ready to go—no peeling needed. Fresh herbs are a must for that bright flavor, but if you're in a pinch, dried thyme at half the amount works too. I always buy extra rosemary because it keeps for months in the freezer if you wrap it tightly in foil.
No fresh rosemary? Dried rosemary at one-third the amount is your best bet. The apple cider vinegar might seem odd, but it's the secret to tender pork—trust me on this. If you're avoiding vinegar, swap it for an extra tablespoon of olive oil and a pinch of sugar. For the broth, low-sodium is key—you don't want to over-salt your dish. The butter on the potatoes? Don't skip it. It gives those spuds that creamy texture that makes this dish unforgettable. And if you're worried about the slow cooker making the potatoes mushy, don't be—the halving and the broth keep them perfectly fluffy.
This dish reheats like a dream—honestly, it tastes even better the next day. Store leftovers in the fridge for up to 4 days, or freeze for 3 months if you're prepping for the week. I always portion the pork and potatoes separately before freezing so I can reheat just what I need. The pork can be marinated overnight in the fridge, which actually makes it even more tender. And if you're serving company, garnish with that dried parsley right before serving—it adds a pop of color that makes the dish look restaurant-worthy.

Step-by-step instructions for herb-infused slow cooker pork tenderloin
This one-pot wonder delivers melt-in-your-mouth pork and fluffy potatoes with minimal effort.
Prep the Pork and Potatoes for Maximum Tender Results
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this helps the seasoning stick and creates a better crust later. Place it in a medium bowl and add 1 tbsp apple cider vinegar, 1.5 tsp salt, 0.5 tsp black pepper, 0.5 cup chopped fresh rosemary, and 0.25 cup fresh thyme leaves. Toss gently to coat evenly, then let it marinate for 15 minutes at room temperature.
Meanwhile, halve the 2 lb baby potatoes (no need to peel) and toss them in a separate bowl with 2 tbsp extra-virgin olive oil, 1.5 tsp salt, and 0.5 tsp black pepper. This pre-seasoning ensures every bite has flavor. Real talk: don't skip the halving—whole potatoes won't cook through properly in the slow cooker.
Layer the Slow Cooker for Perfect One-Pot Magic
Place the marinated pork tenderloin in the bottom of your slow cooker, standing upright. Arrange the halved potatoes around and on top of the pork, creating a single layer. The potatoes should nestle against the pork but not completely cover it—this allows the meat to cook evenly and develop that gorgeous crust.
Pour the 0.5 cup low-sodium chicken broth over everything, then sprinkle the remaining 0.5 cup chopped rosemary and 0.25 cup thyme leaves on top. The broth keeps the pork moist while the herbs infuse every bite with aromatic flavor. Here's the thing—don't overcrowd the slow cooker. If your pork is particularly large, you might need to cook it in batches or use a larger slow cooker.
Cook Until Fork-Tender with Minimal Monitoring
Cover the slow cooker and cook on LOW for 6-7 hours or HIGH for 3-4 hours. The pork is done when it reaches 145°F internal temperature and a fork slides in easily with no resistance. I know it seems like forever, but this slow cooking method transforms tough pork into melt-in-your-mouth perfection.
About 30 minutes before the pork is done, add the 2 tbsp butter to the slow cooker. The heat will melt it into the potatoes, creating tender, buttery spuds with crispy edges. The butter adds richness that balances the herbaceous flavors—don't skip this step (I learned the hard way).
Rest and Serve for Ultimate Juiciness
Once the pork reaches 145°F, carefully remove it from the slow cooker and let it rest on a cutting board for 10 minutes. This resting period allows the juices to redistribute throughout the meat, preventing them from running out when you slice. The potatoes will continue cooking in the residual heat while you rest the pork.
Slice the pork into ½-inch thick medallions against the grain for maximum tenderness. Spoon the herb-infused potatoes around the pork, drizzling any accumulated juices from the slow cooker over everything. Garnish with 1 tsp dried parsley if desired—it adds a pop of color and freshness that ties all the flavors together.
Pro Tips For Making Amazing Pork Tenderloin Slow Cooker Recipe With Potatoes And
- SEAR THE PORK FIRST: I learned this the hard way—skipping the sear means flavor gets lost in the slow cooker. Hit the pork in a hot pan with olive oil for 3-4 minutes per side until golden before transferring it. The crust locks in juices and adds depth the slow cooker alone can’t match.
- PIERCE THOSE POTATOES: Baby potatoes stay stubbornly undercooked if you toss them in raw. Use a fork to poke 2-3 holes in each one before adding them to the slow cooker—this speeds up cooking and prevents a gummy center. (Yes, it looks weird, but trust the process.)
- DON’T OVERFILL THE COOKER: Halfway up the sides is the magic line. Packing the slow cooker too full traps steam, turning your potatoes into sad, soggy mush. Leave room for the pork to release juices and the potatoes to crisp slightly at the edges—crowding guarantees disappointment.
- TOSS IN ROSEMARY LATE: Fresh rosemary burns easily and loses its brightness if it sits in liquid too long. Add the sprigs and whole garlic cloves in the last 30 minutes of cooking. This keeps their aroma sharp and prevents the oil from turning bitter—no one wants herb-flavored bathwater.
Regional styles of this recipe
Southern Comfort Style
In the South, this dish becomes a true showstopper by adding smoked paprika and a splash of hot sauce to the marinade. I like using 1 tsp smoked paprika and 1 tbsp Frank's RedHot for that signature Southern kick.
Serve with a side of cornbread or collard greens to complete the experience. The slow cooker keeps the heat balanced, so you won't end up with overpowering spice—just enough to make it unforgettable. 🌶️
Italian Herb Twist
For an Italian-inspired version, swap the rosemary and thyme for fresh oregano and basil, and add ½ cup sun-dried tomatoes chopped into the marinade. The acidity from the tomatoes pairs beautifully with the pork, and the herbs give it that classic Mediterranean flavor.
I often finish this version with a sprinkle of grated Parmesan cheese and a drizzle of balsamic glaze before serving. It's a game-changer for anyone who loves Italian flavors but wants a hands-off method. 🍅
German-Inspired Sauerkraut
If you're craving something heartier, add 1 cup sauerkraut (drained and rinsed) to the slow cooker alongside the potatoes. The tangy fermented cabbage complements the pork perfectly, and it adds a satisfying crunch.
I also like to include 2 slices of bacon cooked until crispy and crumbled on top for extra richness. This version feels like a cozy German dinner—warm, comforting, and full of flavor. Serve with a side of mustard sauce for dipping. 🥓
Mexican Fiesta Flavor
For a Mexican-inspired twist, add 1 tbsp chili powder, ½ tsp cumin, and ½ tsp garlic powder to the pork marinade. After cooking, serve the pork and potatoes with a side of black beans and sautéed bell peppers.
Top everything with avocado slices and a squeeze of lime for a fresh, vibrant finish. This version is perfect for Taco Tuesday or any night you're craving bold, spicy flavors. 🌮
French Country Classic
To give this dish a French country feel, add 1 tbsp Dijon mustard to the marinade and include ½ cup pearl onions along with the potatoes. The mustard adds depth, while the onions bring a subtle sweetness.
Finish the dish with a sprinkle of fresh parsley and a drizzle of honey to balance the flavors. This version feels elegant but still effortless—perfect for a dinner party or a special occasion. 🥖

Frequently asked questions
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to adjust the cooking time. Cut larger potatoes into 1-inch chunks so they cook evenly in the slow cooker. They'll take about 15-20 minutes longer than baby potatoes to become tender. The key is to avoid overcrowding—leave space between pieces so heat circulates properly.
What if my pork tenderloin is bigger than 1.5 lbs?
For larger tenderloins (up to 2 lbs), increase cooking time by 30-60 minutes on low heat. The meat should reach 145°F internal temperature—use a meat thermometer to check. If your slow cooker is small, consider cooking the pork separately in a skillet first, then adding it to the potatoes for the final 1 hour of cooking.
Can I make this recipe without fresh herbs?
Use 1 tsp dried rosemary and ½ tsp dried thyme instead of fresh. Toast the dried herbs in a dry pan for 1 minute to release their aroma before adding to the marinade. The flavor will be slightly different but still delicious. For extra flavor, add ½ tsp garlic powder to compensate for the missing fresh garlic.
How do I prevent the potatoes from turning mushy?
Halving the potatoes (not quartering) and using a single layer in the slow cooker prevents mushiness. The broth should just barely cover the potatoes—add more if needed. For extra texture, sprinkle 1 tbsp cornstarch over the potatoes 30 minutes before cooking ends to create crispy edges.
Can I make this ahead of time?
This dish actually tastes better reheated! Cook as directed, then refrigerate for up to 4 days or freeze for 3 months. Reheat in the microwave until piping hot (2-3 minutes on high), or warm in a skillet with a splash of broth for crispier edges. The flavors meld beautifully overnight.
