Garlic Butter Pork Tenderloin – Juicy, Flavorful, and Weeknight Easy
Pork tenderloin is one of those cuts that feels fancy but cooks fast. With a golden sear, a splash of butter, and plenty of garlic, you get a main dish that tastes restaurant-worthy with barely any fuss. This version keeps things simple: a handful of pantry spices, a quick stovetop sear, and a short roast in the oven.
The result is juicy slices with garlicky, herby butter melting over the top. It’s the kind of meal you’ll want to make on busy weeknights and for casual company alike.
Ingredients
Method
- Preheat and prep: Set your oven to 400°F (205°C). Pat the pork tenderloin dry with paper towels to help it sear well.
- Season the meat: In a small bowl, mix salt, pepper, paprika, garlic powder, and onion powder. Rub the spice blend all over the pork, pressing it in so it adheres.
- Heat the pan: Place a large oven-safe skillet (cast iron is great) over medium-high heat. Add olive oil and let it shimmer.
- Sear on all sides: Lay the pork in the hot skillet. Sear for about 2 minutes per side until nicely browned, turning with tongs to get color all around. This should take 6–8 minutes total.
- Add the garlic butter: Reduce heat to medium-low. Add the butter to the skillet. When it melts, stir in the minced garlic, thyme, and rosemary. Spoon the foaming butter over the pork for about 30–45 seconds. Don’t let the garlic burn.
- Roast to finish: Transfer the skillet to the oven. Roast for 8–12 minutes, depending on thickness, until the center reaches 140–145°F (60–63°C) on an instant-read thermometer.
- Rest the meat: Move the pork to a cutting board and tent loosely with foil. Rest for 5–10 minutes. This helps the juices redistribute and finish the cook.
- Make it saucy: While the pork rests, return the skillet to low heat. Add lemon juice to the pan and swirl to bring the garlic butter together. Scrape any browned bits for extra flavor.
- Slice and serve: Cut the tenderloin into 1/2-inch slices. Spoon the warm garlic butter over the top and sprinkle with parsley. Serve with mashed potatoes, roasted vegetables, rice, or a crisp salad.
What Makes This Recipe So Good
- Fast and impressive: Pork tenderloin cooks quickly, so you can go from prep to plate in about 30–35 minutes.
- Big flavor, simple ingredients: Garlic, butter, and a few spices create a rich, savory crust and a silky pan sauce.
- Foolproof texture: A quick sear locks in juices; a short roast finishes it gently for tender, sliceable meat.
- Flexible and forgiving: Works in a skillet-to-oven setup or entirely in the oven. Easy to scale for two tenderloins.
- Great for meal prep: Leftovers reheat nicely and make fantastic sandwiches, salads, or grain bowls.
What You’ll Need
- 1 pork tenderloin (about 1 to 1.5 pounds), silver skin trimmed
- 1.5 teaspoons kosher salt
- 1 teaspoon black pepper
- 1 teaspoon smoked paprika (or sweet paprika)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1–2 tablespoons olive oil (or another high-heat oil)
- 4 tablespoons unsalted butter, cut into pieces
- 4–5 fresh garlic cloves, minced

- 1 teaspoon fresh rosemary, finely chopped (or 1/2 teaspoon dried)
- 1 tablespoon lemon juice (optional, for brightness)
- Fresh parsley, chopped, for garnish (optional)
Step-by-Step Instructions
- Preheat and prep: Set your oven to 400°F (205°C).
Pat the pork tenderloin dry with paper towels to help it sear well.
- Season the meat: In a small bowl, mix salt, pepper, paprika, garlic powder, and onion powder. Rub the spice blend all over the pork, pressing it in so it adheres.
- Heat the pan: Place a large oven-safe skillet (cast iron is great) over medium-high heat. Add olive oil and let it shimmer.
- Sear on all sides: Lay the pork in the hot skillet.
Sear for about 2 minutes per side until nicely browned, turning with tongs to get color all around. This should take 6–8 minutes total.
- Add the garlic butter: Reduce heat to medium-low. Add the butter to the skillet.
When it melts, stir in the minced garlic, thyme, and rosemary. Spoon the foaming butter over the pork for about 30–45 seconds. Don’t let the garlic burn.
- Roast to finish: Transfer the skillet to the oven. Roast for 8–12 minutes, depending on thickness, until the center reaches 140–145°F (60–63°C) on an instant-read thermometer.
- Rest the meat: Move the pork to a cutting board and tent loosely with foil.
Rest for 5–10 minutes. This helps the juices redistribute and finish the cook.
- Make it saucy: While the pork rests, return the skillet to low heat. Add lemon juice to the pan and swirl to bring the garlic butter together.
Scrape any browned bits for extra flavor.
- Slice and serve: Cut the tenderloin into 1/2-inch slices. Spoon the warm garlic butter over the top and sprinkle with parsley. Serve with mashed potatoes, roasted vegetables, rice, or a crisp salad.
How to Store
- Refrigerate: Cool completely, then store slices with pan sauce in an airtight container for up to 3–4 days.
- Freeze: Wrap slices tightly and freeze for up to 2 months.
Add a little sauce to keep them moist.
- Reheat gently: Warm in a covered skillet over low heat with a splash of broth or water until just heated through. Avoid the microwave on high; it can dry the pork out.
Why This Is Good for You
- Lean protein: Pork tenderloin is one of the leanest cuts, offering plenty of protein with relatively low fat.
- Micronutrient boost: Pork provides B vitamins like thiamin and B6, which support energy metabolism.
- Flavor without heavy sauces: A modest amount of butter carries the garlic and herbs, so you get big taste with simple, whole ingredients.
- Balanced plate friendly: Pair with veggies and a whole grain for a satisfying, balanced meal.
Pitfalls to Watch Out For
- Overcooking: Pork tenderloin dries out fast past 145°F. Use a thermometer and pull it a few degrees early if needed; carryover heat will finish the job.
- Skipping the rest: Cutting right away sends juices running onto the board.
Resting keeps the meat tender and moist.
- Burning the garlic: Add garlic after searing and keep the heat moderate. If it darkens too fast, pull the pan off the heat briefly.
- Uneven sear: Pat the pork dry and don’t crowd the pan. Moisture or an overloaded skillet prevents browning.
- Wrong cut: Don’t confuse tenderloin with pork loin.
Loin is larger and needs longer cooking.
Variations You Can Try
- Honey Dijon: Whisk 1 tablespoon Dijon and 1 tablespoon honey into the melted butter before basting. Finish with a squeeze of lemon.
- Chili Lime: Swap paprika for chili powder, add lime zest to the butter, and finish with lime juice and cilantro.
- Herb Crusted: Press a mix of chopped parsley, rosemary, thyme, and a bit of panko onto the pork after searing. Roast to finish.
- Smoky Maple: Add 1 tablespoon maple syrup and a pinch of chipotle powder to the butter for sweet heat.
- One-Pan Veggies: Scatter halved baby potatoes and green beans around the pork before it goes into the oven.
Toss the veggies in a little oil and salt first.
FAQ
Can I cook this entirely in the oven without searing?
Yes. Roast at 425°F (220°C) for 18–22 minutes, depending on thickness, until the center hits 140–145°F. Melt the butter with garlic and herbs on the stovetop and spoon it over the sliced pork before serving.
Searing adds flavor, but the oven-only method still works well.
How do I know my pork tenderloin is done?
Use an instant-read thermometer inserted into the thickest part. You’re aiming for 140–145°F. The pork can have a slight blush of pink at this temperature and will be safe and juicy after a short rest.
Can I use salted butter?
You can.
If you do, reduce the kosher salt in the rub slightly, then adjust to taste at the end. The pan sauce will concentrate the seasoning.
What if I don’t have fresh herbs?
Dried thyme and rosemary work fine. Use about half the amount of dried herbs compared to fresh, since dried are more potent.
Add them to the butter early so they can bloom.
How do I scale this for two tenderloins?
Double the seasoning and butter. Sear each tenderloin with enough space in the pan or sear in batches. Arrange both in the oven and add 1–3 extra minutes if needed, checking the internal temperature.
Can I grill the tenderloin?
Yes.
Sear over direct medium-high heat for 2–3 minutes per side, then move to indirect heat, cover, and cook until it reaches 140–145°F. Warm the garlic butter in a small pan and drizzle over the slices.
In Conclusion
Garlic Butter Pork Tenderloin proves that simple techniques and a few good ingredients can deliver big results. With a quick sear, a short roast, and a buttery garlic finish, you get tender, flavorful slices that please everyone at the table.
Keep this recipe in your back pocket for weeknights, but don’t hesitate to serve it to guests. It’s reliable, adaptable, and consistently delicious.
