Garlic Butter Pork Tenderloin and Potatoes - Simple, Comforting, and Flavor-Packed
Ingredients
Method
- Prep and preheat: Heat your oven to 425°F (220°C). Pat the pork dry with paper towels and let it sit at room temperature for 15 minutes. This helps it sear well and cook evenly.
- Season the pork: In a small bowl, mix 1 teaspoon salt, 1/2 teaspoon black pepper, and the smoked paprika. Rub this all over the pork.
- Season the potatoes: Toss the halved potatoes with 1 tablespoon olive oil, a generous pinch of salt and pepper, and half the chopped herbs. Spread them on a large sheet pan or oven-safe skillet, cut side down for best browning.
- Make the garlic butter: In a bowl, combine melted butter, remaining 1 tablespoon olive oil, minced garlic, remaining herbs, and lemon zest. Set aside.
- Sear the pork: Heat a large oven-safe skillet over medium-high heat. Add a drizzle of oil if needed. Sear the pork for 1–2 minutes per side until browned all over, about 6–8 minutes total.
- Combine and baste: If you used a skillet large enough, push potatoes to the edges and place the seared pork in the center. If not, transfer both the seared pork and potatoes to a sheet pan. Spoon about half the garlic butter over the pork and drizzle the rest over the potatoes. Toss potatoes lightly to coat.
- Roast: Roast in the oven for 12–18 minutes, depending on thickness, until the pork reaches an internal temperature of 140–145°F (60–63°C). Stir the potatoes once halfway through for even browning.
- Rest the pork: Transfer the pork to a cutting board and rest 5–10 minutes. This helps keep it juicy. The temperature will rise a few degrees as it rests.
- Optional quick pan sauce: Set the skillet or sheet pan over medium heat on the stovetop. Add 1/4 cup chicken broth to the garlicky drippings and simmer for 1–2 minutes, scraping up browned bits. Spoon over sliced pork.
- Slice and serve: Slice the pork into 1/2-inch medallions. Plate with the roasted potatoes, spooning any extra garlic butter or pan sauce on top. Finish with chopped parsley and a squeeze of lemon.
Why This Recipe Works
This recipe relies on a few smart moves to deliver big flavor. Pork tenderloin cooks quickly and stays tender when you don’t overdo it.
Searing first gives it a deep, savory crust, while finishing in the oven keeps it juicy. The potatoes roast alongside and soak up the garlic butter, so they turn crisp on the outside and fluffy inside.
The garlic butter does the heavy lifting. A mix of butter, olive oil, garlic, and herbs coats both the pork and potatoes, creating a flavorful, glossy finish.
Because it’s mostly hands-off once it goes in the oven, it’s ideal for busy nights.
What You’ll Need
- Pork tenderloin: 1 to 1.5 pounds, trimmed of silver skin.
- Baby potatoes: About 1.5 pounds, halved (Yukon golds or red potatoes work well).
- Butter: 4 tablespoons, melted.
- Olive oil: 2 tablespoons, for searing and roasting.
- Garlic: 4–6 cloves, minced (use more if you love garlic).
- Fresh herbs: 1 tablespoon chopped rosemary and/or thyme (or 1 teaspoon dried each).
- Smoked paprika: 1 teaspoon (optional, for warmth and color).
- Lemon zest: 1 teaspoon, plus lemon wedges for serving (optional but brightens the dish).
- Salt and pepper: Kosher salt and freshly ground black pepper, to taste.
- Chicken broth: 1/4 cup (optional, for a quick pan sauce).
- Fresh parsley: 2 tablespoons, chopped, for garnish.

How to Store
Let leftovers cool, then store in airtight containers.
Keep pork and potatoes together or separate, depending on how you plan to reheat. Refrigerate for up to 3 days.
To reheat, warm gently in a skillet over medium heat with a splash of broth or water until heated through. You can also use the oven at 325°F (165°C) for 10–15 minutes.
The microwave works in a pinch, but cover and use short bursts to avoid drying out the pork.
For freezing, slice the pork and pack with some sauce in freezer-safe bags. Freeze up to 2 months. Thaw overnight in the fridge before reheating.
Why This is Good for You
Pork tenderloin is a lean protein, so you get plenty of protein with less fat than many cuts.
The garlic and herbs bring antioxidants and flavor without extra calories. Potatoes offer potassium and fiber, especially if you keep the skins on.
Yes, there’s butter, which adds richness. But a little goes a long way when you’re coating both the pork and the potatoes.
You can also balance the plate with a simple green side, like steamed broccoli or a salad, for a well-rounded meal.
Common Mistakes to Avoid
- Overcooking the pork: Pork tenderloin is done at 145°F. Pull it from the oven on time and let it rest. Going past 150°F can make it dry.
- Skipping the sear: Searing locks in flavor and creates a satisfying crust.
It’s worth the extra few minutes.
- Crowding the pan: If the potatoes are piled on top of each other, they’ll steam instead of crisp. Use a big pan or two smaller ones.
- Uneven potato sizes: Cut the potatoes to similar sizes so they roast evenly.
- Not drying the pork: Moisture on the surface will prevent a good sear. Pat it dry before seasoning.
Alternatives
- Different potatoes: Swap baby potatoes for Yukon golds or russets cut into 1-inch chunks.
Sweet potatoes also work for a slightly sweeter note.
- Herb switch: Use oregano, sage, or Italian seasoning if you don’t have rosemary or thyme.
- Spice twist: Add a pinch of cayenne or chili flakes for heat, or use cumin and coriander for a warm, earthy profile.
- Dairy-free: Replace butter with plant-based butter or use all olive oil. Add a splash of lemon juice for richness.
- Add veggies: Toss in green beans, carrot sticks, or Brussels sprouts during the last 15–20 minutes of roasting.
- Grill option: Sear the pork on the grill over high heat, move to indirect heat to finish, and roast the potatoes in the oven or on a grill-safe pan.
FAQ
Can I use pork loin instead of tenderloin?
You can, but pork loin is thicker and takes longer. Adjust the time and cook to temperature, not the clock.
Consider slicing the loin into thick chops to sear and roast more quickly.
How do I know the pork is done without drying it out?
Use an instant-read thermometer. Remove the pork at 140–145°F and rest it for 5–10 minutes. It will stay juicy and slightly pink in the center, which is safe at that temperature.
Can I make this ahead?
You can prep the garlic butter and season the pork up to 24 hours ahead.
Keep both refrigerated. For best texture, sear and roast just before serving.
What if I don’t have fresh herbs?
Use dried herbs at about one-third the amount. Dried rosemary and thyme are strong, so start with 1 teaspoon each and adjust to taste.
How can I get extra-crispy potatoes?
Parboil the cut potatoes for 5 minutes, drain well, then toss with oil and roast.
Make sure the pan is hot and the potatoes have space. Flip them once for even browning.
Is there a way to make a creamier sauce?
After deglazing with broth, whisk in a tablespoon of cold butter off the heat for a silky finish. For a creamy version, add a splash of heavy cream and simmer briefly.
What should I serve with this?
Keep it simple with a crisp green salad, roasted asparagus, or sautéed spinach.
A spoonful of grainy mustard or a dollop of herbed yogurt also pairs well.
