Ingredients for amazing pork tenderloin slow cooker recipe with potatoes and
Three star ingredients—juicy pork, crispy potatoes, and bold herbs—all meeting in your slow cooker.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐷 | 1 ½ lb | Center-cut, trimmed of fat |
| Baby Potatoes 🥔 | 2 lbs | Halved, skin-on for crispiness |
| Yellow Onion 🧅 | 1 whole | Sliced into wedges |
| Garlic Cloves 🧄 | 6 cloves | Minced for deep flavor |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems discarded |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Dried Oregano 🍃 | 1 tsp | For earthy depth |
| Apple Cider Vinegar 🍎 | 1 tbsp | Brightens flavors |
| Fresh Parsley 🌿 | 0.1 cup | Chopped, for garnish |
| Butter 🧈 | 2 tbsp | Unsalted, for basting |
The pork tenderloin is non-negotiable here. Center-cut means tender meat, but trim any visible fat—it can make the pork greasy in the slow cooker. Costco or Whole Foods usually have pre-trimmed tenderloins, but if you're buying whole, ask the butcher to cut it for you. Baby potatoes are key for that perfect crispy exterior and creamy interior. Trader Joe's sells them pre-washed, which saves time. Look for potatoes that are firm and free of soft spots—those bruises turn mushy in the slow cooker. The fresh herbs? Grow your own or grab a bunch from the grocery store—they make all the difference over dried.
No fresh rosemary? Dried at half the amount works in a pinch, but trust me, fresh is worth the trip. Running low on apple cider vinegar? White vinegar or lemon juice will do the trick—just use the same amount. The butter is for basting after cooking, but if you're avoiding dairy, olive oil or vegan butter keeps things just as flavorful. Swapping the pork for chicken? Use boneless, skinless thighs—they stay juicier than breasts in the slow cooker. And if you've got extra time, sear the pork first for even deeper flavor. (It's worth the 10 minutes.)
This dish reheats like a dream—honestly better the next day as flavors meld. Store leftovers in the fridge for 4-5 days or freeze for 3 months. I like to portion mine into containers so lunches are ready to grab. The potatoes stay crispy if you reheat them with a splash of water in the microwave for 30 seconds. For extra crispiness, broil them for 2 minutes before serving. And save those juices—drizzle them over everything before eating. That's where the magic happens.

- Rosemary-Kissed Perfection: That sprig of rosemary? It’s the secret weapon. The slow cooker lets it infuse the pork and potatoes with a fragrant, herby depth that’s ridiculously good—like a fancy bistro dish, but with zero fuss. The garlic? It caramelizes just enough to make every bite sing.
- Weeknight to Dinner Party: Between us, this feeds six easily but never feels like a chore. Double the batch for leftovers that reheat beautifully, or serve it as-is for book club—no one will guess it’s a slow cooker meal. (Yes, even on a Tuesday night.)
- Budget-Friendly Luxury: Pork tenderloin is lean but flavorful, and baby potatoes stretch the meal without breaking the bank. The onion and garlic bulk it up, so you’re not just feeding stomachs—you’re satisfying cravings. Honestly, I make this when I want to feel like I’ve treated myself, but the grocery bill stays sane.
Step-by-step instructions for herb-infused pork tenderloin
Here's how to create melt-in-your-mouth pork with crispy potatoes—all in one pot.
🍳 Step 1: Sear the Pork for Maximum Flavor
Heat a large skillet over medium-high heat until hot. Add the 1.5 lb pork tenderloin and sear on all sides for 3-4 minutes per side until it develops a deep golden-brown crust. This step is crucial—it locks in juices and creates that restaurant-quality flavor.
While the pork sears, add 2 tablespoons olive oil to the skillet and let it get hot. Then add the 1 whole yellow onion sliced into wedges and cook for 3-4 minutes until softened. Transfer both to your slow cooker—you're building layers of flavor from the start.
🥘 Step 2: Layer Potatoes and Herbs
Arrange the 2 lbs baby potatoes (halved, skin-on) in a single layer on top of the pork and onions in the slow cooker. This positioning ensures even cooking and prevents the potatoes from turning mushy. Sprinkle the potato layer evenly with 1.5 teaspoons salt, 1 teaspoon black pepper, and 1 teaspoon dried oregano.
Next, create a fragrant herb mixture by combining the 0.25 cup chopped fresh rosemary, 0.25 cup fresh thyme leaves, and 6 cloves minced garlic in a small bowl. Sprinkle this aromatic blend evenly over the potatoes. The herbs will infuse the pork and potatoes with their bright, earthy flavors throughout the cooking process.
🔥 Step 3: Slow Cook to Perfect Tenderness
Set your slow cooker to Low heat and cook for 6-7 hours. This low-and-slow approach ensures the pork tenderloin becomes fork-tender while the potatoes develop a crispy exterior and fluffy interior. Real talk: don't peek at the pork during cooking—every time you lift the lid, you're adding 15-20 minutes to your cook time.
About 30 minutes before the pork is done, add the 1 tablespoon apple cider vinegar to the slow cooker. This brightens the flavors and helps tenderize the meat further. The pork is perfectly cooked when it reaches an internal temperature of 145°F and easily shreds with two forks.
👨🍳 Step 4: Finish with Butter and Garnish
Once the pork is tender, carefully remove it from the slow cooker and shred it using two forks. Return the pork to the slow cooker and stir in the 2 tablespoons butter until melted and evenly distributed. This adds richness and helps create a delicious sauce that coats every bite.
Taste and adjust seasoning if needed—sometimes the potatoes absorb more salt than expected. Garnish with 0.1 cup chopped fresh parsley just before serving. The parsley adds a fresh pop of color and flavor that complements the herb-infused pork beautifully.
⏰ Step 5: Rest and Serve
Let the pork and potatoes rest together in the slow cooker for 10 minutes before serving. This resting period allows the juices to redistribute throughout the meat and potatoes, ensuring each bite is moist and flavorful. Serve immediately with the cooking juices spooned over the top—this creates a delicious sauce that ties everything together.
You'll end up with perfectly tender, herb-infused pork that shreds easily and golden-brown potatoes with crispy edges. The combination of flavors and textures makes this one-pot meal truly amazing—exactly what you promised yourself when you started this recipe.
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 makes the pork taste like it’s been simmering in its own juices the whole time. Hit a screaming-hot skillet with a little oil, get those edges golden in 2-3 minutes per side before tossing it in the slow cooker. The crust locks in flavor and makes the whole dish taste restaurant-worthy.
- PUNCTURE THOSE POTATOES: Baby potatoes? They’re stubborn little things. Quarter them (yes, even if they’re small) and stab each piece with a fork—twice—before adding them to the slow cooker. I used to skip this, and they’d turn to mush instead of crispy edges. A quick stab guarantees they’ll soften evenly without falling apart.
- DON’T OVERCROWD THE POTS: This isn’t the prettiest method, but it’s the tastiest: cook the potatoes in batches if needed. A packed slow cooker steams instead of roasts, leaving you with sad, soggy spuds. Layer them loosely—just enough to fit snugly—and resist the urge to shove them all in at once.
- TOSS IN ROSEMARY LATE: Fresh rosemary needs time to infuse, but too early and it turns bitter. Tuck 2-3 sprigs into the pork after the first 2 hours of cooking, or add them right before serving. I was skeptical until I tried it—now I swear by it for that bright, herbal finish without the harsh aftertaste.
Health benefits of these flavors

Fresh rosemary and thyme aren’t just for flavor—they’re packed with antioxidants like carnosic acid and rosmarinic acid that fight inflammation. These herbs also contain vitamin K and iron, which support bone health and energy levels. Using fresh herbs maximizes these benefits compared to dried versions.

Frequently asked questions
Can I use regular potatoes instead of baby potatoes?
You can, but baby potatoes give you that perfect crispy exterior and creamy interior without needing extra time. For regular potatoes, cut them into 1-inch chunks and increase cooking time by 30-45 minutes on Low. They'll still work, but baby potatoes are ideal for this one-pot magic.
What if my pork tenderloin is still tough after 6-7 hours?
This usually happens if the pork wasn't seared first or if you peeked at it too often. For next time, try searing the pork longer (5 minutes per side) and add 1 tablespoon extra apple cider vinegar during the last hour. If it's still tough, shred it and use it in sandwiches or tacos—it'll be more flavorful!
Can I make this recipe in an Instant Pot instead?
Sear the pork and onions first, then add potatoes and herbs. Cook on High pressure for 20 minutes (natural release). The Instant Pot version takes about 45 minutes total instead of hours. Just be careful not to overfill the pot—leave 1-inch headspace for steam.
How do I store leftovers?
Store in an airtight container in the fridge for 4-5 days or freeze for 3 months. To reheat, cover with a damp paper towel and microwave for 2-3 minutes on medium power. For crispy potatoes, pop them under the broiler for 2-3 minutes before serving. The juices will keep everything moist!
What are some good sides to serve with this?
This dish is already complete, but if you want extras, try a simple green salad with vinaigrette or steamed green beans with garlic. For something heartier, add crusty bread to soak up those delicious juices. The pork and potatoes are the stars, so keep sides light to avoid overwhelming the meal.
