Ingredients for amazing pork tenderloin slow cooker recipe with potatoes and

Pantry staples and fresh herbs create this melt-in-your-mouth pork tenderloin with golden potatoes.

Ingredient Amount Notes
Pork Tenderloin 🥩 1 ½ lb Center-cut, trimmed of fat
Baby Potatoes 🥔 2 lbs Red or Yukon gold, halved
Garlic Cloves 🧄 6 cloves Minced, for marinade
Fresh Rosemary 🌿 ¼ cup Chopped, stems removed
Fresh Thyme 🌿 ¼ cup Leaves only, chopped
Honey 🍯 2 tbsp Raw or clover variety
Olive Oil 🫒 ½ cup Extra-virgin, for marinade
Salt 🧂 1 ½ tsp Kosher salt, divided
Black Pepper 🌶️ 1 tsp Freshly ground
Balsamic Vinegar 🍶 1 tbsp For marinade depth
Dijon Mustard 🍯 1 tbsp For marinade tang
Butter 🧈 2 tbsp Unsalted, for crisping potatoes
Parmesan Cheese 🧀 ¼ cup Freshly grated, for topping

The pork tenderloin is the star, so pick a center-cut piece—it's more tender and cooks faster. Costco or Whole Foods usually have the best quality, but any grocery store's meat counter works. Look for good marbling but not too much fat. I always trim the fat myself with kitchen shears—takes 30 seconds and makes a difference. Baby potatoes are a game-changer here—they cook evenly and get perfectly crispy. Red potatoes hold their shape best, but Yukon golds add creaminess. Halve them before adding to the slow cooker so they absorb all that flavor.

No fresh rosemary? Dried works at one-third the amount, but fresh has that piney aroma that's essential. Short on time? Pre-minced garlic from the jar saves chopping, though fresh is always better. The honey can be swapped for maple syrup if you prefer, but honey adds that perfect balance of sweetness. For the mustard, Dijon is non-negotiable—it gives that tangy depth. No balsamic vinegar? A splash of apple cider vinegar works in a pinch. The butter for crisping? Use full-fat—low-fat won't brown the same. And trust me, the Parmesan on top is worth the extra minute of grating.

Marinate the pork for at least 2 hours—overnight is ideal. Store the marinade in a sealed container in the fridge. Potatoes keep 1 week unpeeled in a cool, dark place. The cooked pork and potatoes reheat beautifully—just pop them in the oven at 350°F for 15-20 minutes with a splash of water. I always make double portions because leftovers taste even better the next day. Freeze portions in airtight containers for up to 3 months—perfect for lazy weeknights.

Why You'll Love This Recipe

  • Herb-Packed Magic: That rosemary and thyme? They turn simple pork into something ridiculously good. The garlic cloves caramelize just enough to add depth without overpowering, and the potatoes? Buttery, crispy edges that disappear faster than my willpower on a Tuesday.
  • Weeknight to Dinner Party: Same recipe, different vibes. Serve it with crusty bread for a lazy Sunday supper or add a drizzle of honey-mustard glaze for a dinner party that actually impresses. Between us, I’ve pulled this off for both—and no one ever guessed how little effort it took.
  • Leftovers That Don’t Suck: Most slow-cooker pork dries out by day two. Not this. The tenderloin stays juicy, the potatoes soften just enough to reheat perfectly, and the herbs keep it from tasting like yesterday’s lunch. I’ve packed this for lunches, frozen portions for busy nights, and still crave it days later.

Step-by-step instructions for slow-cooked pork tenderloin with crispy potatoes

This one-pan wonder delivers melt-in-your-mouth pork and perfectly crispy potatoes every time.

1

👨‍🍳 Step 1: Create the Ultimate Herb Marinade

In a medium bowl, whisk together the 0.5 cup olive oil, 2 tbsp honey, 1 tbsp balsamic vinegar, 1 tbsp Dijon mustard, 1.5 tsp salt, and 1 tsp black pepper. Add the 6 cloves minced garlic, 0.25 cup chopped fresh rosemary, and 0.25 cup chopped fresh thyme. Mix until everything is thoroughly combined—you want the herbs to release their oils and aromas into the marinade.

Place the 1.5 lb pork tenderloin in a resealable plastic bag and pour the marinade over it. Gently massage the marinade into all sides of the pork, making sure it's well coated. Seal the bag and refrigerate for at least 1 hour (overnight works even better). This marinating step is what makes the pork incredibly tender and flavorful—don't skip it!

2

🍳 Step 2: Prep the Potatoes for Maximum Crispiness

While the pork marinates, halve the 2 lbs baby potatoes and place them in a large bowl. Drizzle with 1 tbsp olive oil (reserve the rest for the slow cooker), 0.5 tsp salt, and 0.5 tsp black pepper. Toss gently to coat, making sure each potato half gets an even distribution of oil and seasoning. Here's the thing—tossing them now prevents them from sticking together in the slow cooker later.

Spread the seasoned potatoes on a baking sheet lined with parchment paper and place them in the refrigerator for 30 minutes. This chilling step helps them crisp up beautifully in the slow cooker. While they're chilling, preheat your slow cooker on HIGH for 10 minutes to get it nice and hot for the pork.

3

🔥 Step 3: Brown the Pork for Extra Flavor

Remove the pork from the marinade (reserve the marinade) and pat it dry with paper towels. Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the pork and sear for 2-3 minutes per side until it develops a beautiful golden-brown crust. This quick sear adds incredible depth of flavor that the slow cooking can't achieve alone.

Transfer the seared pork to your preheated slow cooker. Pour the reserved marinade over the pork, tilting the slow cooker slightly to ensure the pork is fully coated. The marinade will help keep the pork moist during the long cook and infuse it with those amazing herb flavors.

🥘 Step 4: Layer and Cook for Perfect Results

Arrange the chilled potatoes around the pork in a single layer. They should fit snugly but not be overcrowded—this ensures they'll get crispy. Drizzle any remaining olive oil from the skillet over the potatoes, then sprinkle with the 2 tbsp butter and 0.25 cup freshly grated Parmesan cheese. Cover the slow cooker and cook on LOW for 6-7 hours (or HIGH for 3-4 hours).

About 30 minutes before the cooking time is up, uncover the slow cooker and increase the heat to HIGH. This final burst of heat helps crisp the potatoes to perfection. You'll know they're done when the pork reaches an internal temperature of 145°F (use a meat thermometer) and the potatoes are fork-tender with crispy edges. The pork should pull apart easily with two forks.

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 flavorless pork. Hit the tenderloin with a hot pan for 2-3 minutes per side until golden before tossing it in the slow cooker. The crust locks in juices and adds depth the slow cooker alone can’t match.
  • PEEL AND HALVE THOSE POTATOES: Baby potatoes stay stubbornly undercooked in a slow cooker. Peel them first (yes, even the small ones) and halve them—this speeds up cooking and guarantees tender, fluffy centers. Toss them in the pot raw; they’ll absorb all the pork’s juices like a sponge.
  • SKEWER THE HERBS: Fresh rosemary and thyme lose their punch when left loose in the slow cooker. Thread 2-3 sprigs onto a wooden skewer, then pierce the pork tenderloin with it before adding everything to the pot. The herbs stay concentrated against the meat where they matter most.
  • DON’T OVERFILL THE POT: I used to cram everything in, thinking more = better. This recipe needs breathing room—fill the slow cooker only 2/3 full. Crowding turns the potatoes mushy and steams the pork instead of letting it cook evenly. Less is more; trust me.

Regional styles of this dish

Southern Comfort

In the South, pork tenderloin with potatoes becomes a showstopper with a few regional twists. I love adding 1 tbsp smoked paprika to the marinade for that signature Southern smokiness, then finishing with a sprinkle of crumbled bacon on top before serving.

The bacon adds a salty crunch that pairs perfectly with the crispy potatoes. My grandmother always served this with a side of buttermilk biscuits—the contrast of tender pork and flaky biscuits is pure Southern comfort. 🍖

Italian-Inspired

For an Italian twist, swap the rosemary and thyme for 1 tbsp dried oregano and 1 tsp dried basil in the marinade. Add 1 tbsp tomato paste to the marinade for depth, and finish the dish with a sprinkle of fresh basil and a drizzle of balsamic glaze before serving.

Serve with a side of garlic bread and a simple arugula salad with lemon vinaigrette for a meal that feels like you're dining in Tuscany. 🍝

German-Style

In Germany, pork tenderloin is often paired with root vegetables and a touch of mustard. For this version, add 1 tbsp whole-grain mustard to the marinade and include 1 lb baby carrots and 1 small onion, sliced, along with the potatoes.

After slow cooking, finish with a sprinkle of fresh parsley and serve with a side of sauerkraut for a hearty, satisfying meal. The tangy mustard and sauerkraut add a perfect balance to the tender pork and crispy potatoes. 🥬

Mexican Fiesta

Give this dish a fiesta flair by adding 1 tsp ground cumin, 1 tsp chili powder, and ½ tsp cayenne pepper to the marinade. Serve the pork and potatoes with a side of black beans and corn salsa.

Top with avocado slices, crumbled cotija cheese, and a squeeze of lime for a vibrant, flavor-packed meal that feels like a Mexican fiesta. The heat from the spices complements the sweetness of the honey in the marinade beautifully. 🌶️

French Country

For a French-inspired version, use white wine instead of balsamic vinegar in the marinade—about 2 tbsp will do. Add 1 sprig of fresh tarragon to the marinade and finish the dish with a sprinkle of toasted breadcrumbs and chopped parsley.

Serve with a side of creamy mashed potatoes (yes, even with the crispy potatoes!) and a simple green salad with Dijon vinaigrette. This version feels elegant yet effortless, perfect for a cozy French country dinner. 🥖

Frequently asked questions

1

Can I use regular potatoes instead of baby potatoes?

You can, but baby potatoes give the best texture—halving them ensures they cook evenly and develop that perfect crispy exterior. If using larger potatoes, cut them into 1-inch chunks and increase cooking time by 30-45 minutes on LOW. The key is avoiding overcrowding so they can crisp properly.

2

What if my pork tenderloin is still pink inside?

Pork tenderloin is safe to eat when it reaches 145°F internally, but it can still look pink due to its natural color. Use a meat thermometer to confirm doneness—if it's 145°F, it's perfectly cooked. For extra peace of mind, let it rest 5 minutes before slicing, as the temperature will rise another 5°F.

3

Can I make this in an Instant Pot instead?

Sear the pork first, then add potatoes and 1 cup broth to the Instant Pot. Cook on HIGH PRESSURE for 20 minutes, then quick-release and let sit 5 minutes before transferring to a baking sheet to crisp. The Instant Pot cooks faster but requires the oven finish for crispy potatoes.

4

How do I prevent the potatoes from getting mushy?

Chilling the potatoes before cooking and using HIGH heat for the last 30 minutes are key. Also, make sure they're in a single layer—not stacked—and don't overcrowd the slow cooker. A light drizzle of olive oil before cooking helps create that crispy crust.

5

What sides pair well with this dish?

This hearty meal stands alone, but if you want extras, try green beans with almonds, a simple arugula salad, or crusty sourdough bread. For a Southern touch, buttermilk biscuits cut through the richness beautifully. The crispy potatoes and tender pork are already a match made in heaven!
