Ingredients
- 1 pork tenderloin (about 1 to 1.5 pounds), silver skin trimmed
- 1.5 teaspoons kosher salt
- 1 teaspoon black pepper
- 1 teaspoon paprika (smoked or sweet)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried thyme or Italian seasoning
- 1–2 tablespoons olive oil
- 3 tablespoons unsalted butter, softened
- 3–4 cloves garlic, finely minced
- 1 tablespoon fresh parsley, finely chopped (plus more for garnish)
- 1 teaspoon lemon zest (optional, but brightens the butter)
- Fresh lemon wedges, for serving (optional)
How to Make It
- Preheat the air fryer: Set to 400°F (200°C) for 5 minutes so it’s hot when the pork goes in.A preheated basket helps create a better sear.
- Prep the tenderloin: Pat the pork dry with paper towels. Dry meat browns better and helps the rub stick.
- Mix the seasoning: In a small bowl, combine salt, pepper, paprika, garlic powder, onion powder, and thyme.
- Season and oil: Rub the pork with olive oil, then coat evenly with the seasoning mix, pressing it onto all sides.
- Make the garlic butter: In another bowl, mash together softened butter, minced garlic, parsley, and lemon zest (if using). Set aside.
- Air fry, first stage: Place the pork in the air fryer basket. Cook at 400°F for 10 minutes.
- Flip and finish: Flip the tenderloin.Cook another 8–12 minutes, depending on thickness, until the internal temperature reaches 140–145°F (60–63°C) in the thickest part.
- Baste with garlic butter: In the last 2–3 minutes of cooking, spread half the garlic butter over the top so it melts and coats the pork.
- Rest the meat: Transfer to a cutting board and tent loosely with foil. Rest 5–8 minutes. This keeps the juices inside.
- Slice and serve: Slice into 1/2-inch rounds.Spoon on the remaining garlic butter, garnish with parsley, and add a squeeze of lemon if you like.
Garlic Butter Air Fryer Pork Tenderloin
Crisp outside, juicy inside, and drenched in garlicky herb butter
Ingredients — Pork & Rub
- 1 pork tenderloin (about 1–1.5 lbs), silver skin trimmed
- 1½ tsp kosher salt
- 1 tsp black pepper
- 1 tsp paprika (smoked or sweet)
- 1 tsp garlic powder
- ½ tsp onion powder
- ½ tsp dried thyme or Italian seasoning
- 1–2 tbsp olive oil
Ingredients — Garlic Butter
- 3 tbsp unsalted butter, softened
- 3–4 cloves garlic, finely minced
- 1 tbsp fresh parsley, finely chopped (plus more for garnish)
- 1 tsp lemon zest (optional, but brightens the butter)
For Serving
- Fresh lemon wedges (optional)
Instructions
- Preheat the Air FryerSet to 400°F (200°C) and preheat for 5 minutes. A hot basket creates a better sear from the start.Never skip the preheat — a cold basket leads to pale, uneven browning.
- Season the PorkPat the tenderloin completely dry with paper towels. Mix salt, pepper, paprika, garlic powder, onion powder, and thyme. Rub the pork with olive oil, then coat evenly with the spice mix, pressing it onto all sides.Dry meat browns better and helps the rub stick — this step makes a real difference.
- Make the Garlic ButterMash together softened butter, minced garlic, parsley, and lemon zest (if using) in a small bowl. Set aside.
- Air Fry — First StagePlace the pork in the air fryer basket. Cook at 400°F for 10 minutes.
- Flip, Baste & FinishFlip the tenderloin. Cook another 8–12 minutes depending on thickness, until internal temperature reaches 140–145°F in the thickest part. In the last 2–3 minutes, spread half the garlic butter over the top so it melts and coats the pork.Use an instant-read thermometer — pork tenderloin dries out fast past 150°F. Pull at 140–145°F and let carryover heat finish the job.
- Rest, Slice & ServeTransfer to a cutting board and tent loosely with foil. Rest 5–8 minutes. Slice into half-inch rounds. Spoon the remaining garlic butter over the slices, garnish with parsley, and add a squeeze of lemon if desired.Resting keeps the juices inside — slicing too early means dry, pale medallions instead of juicy, glossy ones.
Tips for the Best Results
- Always preheat the air fryer — a cold basket means pale, uneven results.
- Trim the silver skin before cooking — it causes curling and stays tough and chewy.
- Pat the pork bone-dry before seasoning for the best sear and rub adhesion.
- Pull at 140–145°F and rest 5–8 minutes — carryover heat finishes cooking safely.
- Baste with garlic butter in the last 2–3 minutes only — adding it too early means it drips off before the crust sets.
- Make the garlic butter up to 3 days ahead and refrigerate. Let it soften slightly before basting.
- If cooking two tenderloins, leave space between them so air circulates — crowding causes steaming, not crisping.
Storage Instructions
- Refrigerate: Store cooled leftovers in an airtight container for up to 3–4 days.
- Freeze: Wrap tightly and freeze for up to 2 months. Thaw in the fridge overnight.
- Reheat: Warm gently in a covered skillet with a splash of broth or water over low heat, or in the air fryer at 300°F for 4–6 minutes. Avoid overcooking.
- Sauce saver: If you have leftover butter, melt it and drizzle over reheated slices to keep them juicy.

Recipe Variations
- Maple Dijon: Swap garlic powder and paprika for 2 teaspoons Dijon mustard and 1 tablespoon maple syrup. Brush on during the last 5 minutes.

FAQ
How long does pork tenderloin take in the air fryer?
For a 1 to 1.5-pound tenderloin, plan on 18–22 minutes at 400°F, flipping halfway. Always use a thermometer and cook to 140–145°F, then rest before slicing.
Jump to RecipeCan I cook two tenderloins at once?
Yes, if your air fryer is large enough to allow space around each piece. Cook time may increase by a few minutes.
Check both tenderloins for temperature individually.
Do I need to marinate the pork?
No. The dry rub and garlic butter add plenty of flavor. If you have time, a quick 30-minute marinade won’t hurt, but it’s not required.
What if my tenderloin is thicker or thinner?
Adjust the time.
Thicker pieces may need a few extra minutes; thinner ones may be done faster. Start checking temperature early to avoid overcooking.
Can I make this dairy-free?
Yes. Use a plant-based butter or olive oil-garlic mixture instead of regular butter.
The technique stays the same.
How do I keep the pork from drying out?
Don’t overcook, and let it rest. Basting with garlic butter in the final minutes adds moisture and flavor that helps keep slices juicy.
Jump to RecipeWhat sides go best with this?
Great options include roasted or air-fried potatoes, green beans, asparagus, a simple arugula salad, or creamy polenta.
Is pork tenderloin the same as pork loin?
No. Tenderloin is smaller, leaner, and cooks faster.
Pork loin is larger and requires longer cooking. This recipe is written specifically for tenderloin.
Can I make the garlic butter ahead of time?
Absolutely. Mix it up to 3 days in advance and keep it in the fridge.
Let it soften slightly before basting.
What temperature should I rest the pork to?
Remove at 140–145°F. Carryover heat will keep it safe and tender while it rests for 5–8 minutes.
