Mastering pork tenderloin and potatoes in a single pan transforms weeknight dinners into restaurant-quality meals with minimal effort.
Growing up in small-town Georgia, I learned that the secret to perfect pork lies in precise seasoning and gentle cooking—techniques I’ve refined over years of preparing 2,000 pounds of it weekly at my Atlanta restaurant.
This recipe delivers juicy, tender pork paired with crispy, herbed vinegar potatoes, all achieved in one pan.
The beauty of this method is its simplicity: no complicated steps, just a well-seasoned pork tenderloin and potatoes tossed in a tangy vinegar crisp that caramelizes into golden perfection.
I use a blend of apple cider vinegar and fresh herbs to create a crust on the potatoes while keeping the pork moist—critical for that melt-in-your-mouth texture. The key is cooking the pork first, then adding the potatoes to the same pan, allowing their flavors to meld together beautifully.
By the time you’re done, you’ll have a plate that’s as impressive as it is delicious: a perfectly seared pork tenderloin with a rosy center, surrounded by crispy, aromatic potatoes that hold their shape.
The herbed vinegar crisp adds a bright, tangy contrast that cuts through the richness of the pork, making every bite balanced and satisfying. This dish is foolproof, elegant, and perfect for feeding a family or impressing guests without the fuss.
Serve with a simple green salad or steamed vegetables to round out the meal. The leftovers reheat well, too, making this an ideal recipe for meal prep. Let’s get cooking—your dinner table is about to get an upgrade.
Ingredients for pork tenderloin potatoes
Fresh herbs and tangy vinegar transform simple pork and potatoes into restaurant-worthy one-pan magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Baby Potatoes 🥔 | 1 ½ lb | Yukon gold or red, halved if large |
| Apple Cider Vinegar 🍏 | ¼ cup | Raw, unfiltered preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For searing pork |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for crisp |
| Fresh Rosemary 🌿 | ½ tsp | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ½ tsp | Leaves only, chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced, for potatoes |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely ground |
| Granulated Garlic 🧄 | ½ tsp | For potato seasoning |
| Dried Oregano 🍃 | ¼ tsp | Mediterranean blend preferred |
The pork tenderloin is your star—center-cut with that pink center you crave. Costco or Whole Foods carry the best quality, but any butcher will trim it for you if you ask. Look for pieces that are firm to the touch, not spongy. I like to pat mine dry with paper towels before seasoning—absorbs the crust better. The potatoes? Yukon golds caramelize beautifully, but red potatoes stay crispier. Halve any larger ones so they cook evenly in the same time as the pork. Fresh herbs make all the difference here—Trader Joe's sells pre-chopped blends, but I always grab whole sprigs and chop them myself.
No fresh rosemary? Dried works at half the amount, but it lacks that piney brightness. Apple cider vinegar substitute? White wine vinegar or lemon juice—just add a pinch of sugar to balance. The butter is non-negotiable for crisp—use full-fat or it won't brown right. For the potatoes, if you're short on time, microwave them 5 minutes first to cut cooking time. The garlic powder can be swapped for fresh minced garlic, but it burns faster. And if you're watching salt, reduce the kosher salt by half and add a pinch of smoked paprika for depth.
This dish reheats like a dream—just 2 minutes in the microwave with a splash of water to keep it moist. Store leftovers in the fridge for 4 days in an airtight container. For meal prep, I portion the pork and potatoes separately so they stay crispy. The vinegar crisp on the potatoes gets even better the next day—worth making extra. Freezes beautifully for 3 months if you want to prep ahead for busy nights.

Step-by-step instructions for pork tenderloin and potatoes roast
This one-pan method delivers perfectly tender pork and crispy potatoes with minimal effort.
Prep and Season the Pork Tenderloin
Remove the pork tenderloin from the refrigerator and pat it completely dry with paper towels. This step is crucial for achieving crispy skin later. Place the meat on a cutting board and season generously with 1.5 teaspoons of diamond crystal kosher salt and 0.5 teaspoon of freshly ground black pepper on all sides. Let it sit at room temperature for 15-20 minutes while you prepare the potatoes.
While the pork rests, halve the baby potatoes if they're large, then place them in a large bowl. Toss them with 2 tablespoons of extra-virgin olive oil, 0.5 teaspoon of granulated garlic, 0.25 teaspoon of dried oregano, and 0.5 teaspoon of diamond crystal kosher salt. This coating ensures even seasoning and helps create crispy edges during roasting.
Sear the Pork and Roast Together
Preheat your oven to 425°F. Heat a large oven-safe skillet over medium-high heat and add 2 tablespoons of unsalted butter and 2 tablespoons of extra-virgin olive oil. Once the butter foams, add the pork tenderloin and sear for 3-4 minutes per side until it develops a golden-brown crust. This initial sear locks in juices and creates flavor.
Remove the pork from the skillet and transfer it to a plate. Add the seasoned baby potatoes to the same skillet in a single layer, making sure they're not overcrowded. Roast in the preheated oven for 20 minutes, stirring halfway through to ensure even browning. This initial roast gets the potatoes started on their way to crispy perfection.
Deglaze and Create the Vinegar Crisp
After 20 minutes, remove the skillet from the oven and carefully pour in 0.25 cup of apple cider vinegar. Use a wooden spoon to scrape up all the browned bits from the bottom of the pan—this creates the flavorful base for your crisp. Return the skillet to the oven and continue roasting for another 10-15 minutes until the potatoes are tender when pierced with a fork.
During this time, the vinegar will bubble and reduce, creating a glossy, herbed crisp that coats the potatoes. The pork should reach an internal temperature of 145°F when measured with a meat thermometer. This crisp adds a tangy contrast to the rich pork and tender potatoes, making every bite exciting.
Finish with Herbs and Rest
Once the pork reaches the proper temperature and the potatoes are fork-tender, remove the skillet from the oven. Sprinkle the 0.5 teaspoon of fresh rosemary and 0.5 teaspoon of fresh thyme evenly over the top, then return the skillet to the oven for 2-3 minutes to let the herbs infuse their aroma into the dish.
Transfer the pork tenderloin to a cutting board and let it rest for 5 minutes before slicing. This resting period allows the juices to redistribute, ensuring each slice remains moist and tender. Serve the pork alongside the crispy potatoes and that delicious herbed vinegar crisp for a complete, satisfying meal.
Pro Tips For Making Pork Tenderloin Potatoes
- Sear the Pork First: Walk the pork tenderloin straight from the fridge to a screaming-hot pan with 2 tablespoons of olive oil—no thawing, no warming. The shock of heat locks in juices better than any slow start, and those caramelized edges where the butter pools? That’s where the flavor lives. (Yes, even if you’re impatient like me.)
- Parboil Potatoes Twice: Baby potatoes need two quick dips in boiling water: first for 5 minutes to soften, then a 30-second rinse under cold water to stop cooking. This guarantees they’ll finish crispy in the pan without turning gluey—no more sad, mealy potatoes ruining your effort.
- Use Vinegar Early: Toss the potatoes with apple cider vinegar before they hit the pan, not after. The acid breaks down their skins slightly, making them crispier faster. Skip this, and you’ll end up with a pan full of steam instead of golden bites.
- Baste with Butter: After searing the pork, pull it from the pan and let it rest while you melt 2 tablespoons of unsalted butter with a splash of vinegar. Spoon that glossy liquid over the pork just before serving—it’s the lazy person’s way of making everything taste restaurant-worthy.
Serving suggestions for this pork tenderloin potatoes
Plating Like a Pro
For that restaurant-worthy presentation, slice the pork tenderloin into ½-inch thick medallions and arrange them fan-style on each plate. The crispy potatoes should go in a loose pile beside the pork, with the herbed vinegar crisp glistening visibly.
I like to add a few extra sprigs of fresh rosemary and thyme as garnish—just a quick sprinkle before serving. This keeps the dish looking fresh and intentional. 🌿
Green Salad Pairing
A simple arugula salad with lemon vinaigrette cuts through the richness beautifully. Toss 4 cups baby arugula with 2 tbsp extra-virgin olive oil, 1 tbsp fresh lemon juice, ½ tsp Dijon mustard, and a pinch of salt.
Top with shaved Parmigiano-Reggiano for a touch of elegance. The peppery bite balances the pork's richness perfectly.
Bread Service
Serve with a warm, crusty sourdough loaf or brioche rolls for soaking up the herbed vinegar crisp. I often toast the bread lightly and brush it with garlic-infused olive oil before serving. The contrast of soft bread against the crispy potatoes adds another delicious texture layer. 🥖
Sauce Elevations
For an extra touch, drizzle each plate with a honey-mustard glaze (mix 1 tbsp Dijon mustard, 1 tbsp honey, and 1 tsp apple cider vinegar). This adds a sweet-tangy contrast that complements the savory pork.
Alternatively, a chive cream sauce (whisk ¼ cup sour cream with 1 tbsp chopped chives) adds richness without overpowering.
Family-Style Serving
For a cozy family meal, keep everything in the same skillet and serve it family-style at the center of the table. The shared pan creates a communal dining experience, and everyone can help themselves to pork and potatoes.
This works especially well during holidays or when entertaining—it feels warm and inviting. 🏡
Leftovers Reinvented
Transform leftover pork into pork pot pie by mixing shredded pork with potatoes, adding a splash of cream, and topping with puff pastry. Or make pork fried rice with leftover potatoes, scrambled eggs, and soy sauce. These creative uses keep the meal exciting for days after the original dinner. 💡

Frequently asked questions
Why do you recommend baby potatoes for this recipe?
Baby potatoes cook faster and develop crispy edges perfectly in the same time as the pork tenderloin. Their smaller size means no need to halve them, and they absorb the herbed vinegar crisp beautifully.
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to cut them into 1-inch chunks and increase oven time by 5-10 minutes. Yukon golds work best—they caramelize without falling apart. Halve large potatoes to ensure even cooking alongside the pork.
What's the best way to check if the pork tenderloin is done?
Use a meat thermometer to check the thickest part—it should read 145°F internally. The pork will pull away slightly from the bone and have a juicy pink center. Never rely on color alone, as overcooking leads to dry meat.
Can I make this recipe without fresh herbs?
Use ½ teaspoon dried rosemary and ½ teaspoon dried thyme in place of fresh. Add them with the vinegar at the end of cooking. For extra flavor, sprinkle with ½ teaspoon garlic powder when tossing the potatoes.
How do I prevent the potatoes from burning before the pork is done?
Roast the potatoes alone for 20 minutes first, then add the pork back in for the final 10-15 minutes**. This staggered approach ensures both components cook perfectly. Stir the potatoes halfway to promote even browning.
