How long to cook pork tenderloin in an air fryer (with temp + tips)

Cook a whole pork tenderloin (450-680g / 1-1.5 lb) in an air fryer at 200°C / 400°F for 20 to 22 minutes, flipping at the halfway mark. Pull at 63°C / 145°F internal at the thickest centre — the USDA safe minimum for whole pork since 2011. Rest 5 minutes loosely tented; carryover brings it to 66°C / 150°F. Slice across the grain for tender bites.

Temperature 200°C 400°F

Time 20–22 min at recommended size

Internal temp 63°C 145°F

Time by size

Size	Time
Small (450g / 1 lb)	16–19 min
Standard (565g / 1.25 lb)	20–22 min
Large (680g+ / 1.5 lb+)	24–28 min

Step-by-step method

Preheat the air fryer to 200°C / 400°F for 3 minutes.
Trim the silverskin (the silvery membrane on top) — it doesn't render and goes chewy.
Pat dry, brush with oil, season generously.
Place in the basket; for longer fryers leave straight, for shorter ones bend it slightly.
Cook 11 minutes, flip, cook 9 to 11 more minutes.
Verify temp at the thickest centre — pull at 63°C / 145°F.
Rest 5 minutes loosely tented before slicing across the grain.

How to tell it's done

Surface should be deeply golden brown all over. Internal temp at the thickest part reads 63°C / 145°F. Sliced, the centre should be just barely pink — safe, juicy, and tender. Past 68°C / 154°F the meat tightens and goes from buttery to firm; past 72°C / 162°F it's dry.

Common mistakes

Leaving the silverskin. The silvery membrane on top doesn't render — it tightens during cooking, making slices chewy. Slip a knife under and peel it off.
Cooking to 71°C / 160°F. Old recipes call for higher temps; the USDA lowered safe minimum to 63°C / 145°F in 2011. Past that, you're drying out the meat.
No rest. 5 minutes loosely tented is non-negotiable for tenderloin — it's lean, and juices need time to redistribute.
Slicing with the grain. Tenderloin's muscle fibres run lengthwise — slice across them (perpendicular) for tender, short fibres.
Cooking too cold. 30 minutes on the counter before cooking gives a more even centre-to-edge cook.

Why it works

Pork tenderloin is the leanest cut of pork — about 4% fat, similar to skinless chicken breast. That leanness makes it cook fast and dry out fast. The 2011 USDA safe minimum of 63°C / 145°F respects how lean it is: cooking past that doesn't make it safer, it just removes more moisture. The 5-minute rest is critical because lean meat has no fat reservoir to keep juices from running out.

Frequently asked questions

Do I need to remove the silverskin?

Yes. The silvery membrane on top of pork tenderloin doesn't render during cooking — it tightens, making the cooked meat chewy. Slip a sharp knife under it at one end and slowly peel it off in long strips.

What temperature is safe for pork tenderloin?

63°C / 145°F internal at the thickest part (USDA safe minimum since 2011). After a 5-minute rest, carryover cooking brings it to about 66°C / 150°F. The centre stays slightly pink and juicy — that's correct.

Should I bend the tenderloin to fit the basket?

If your air fryer is shorter than the tenderloin, gentle bending is fine. The meat cooks evenly because air circulates around the curve. Don't fold it sharply — that creates a thick spot that won't cook through.

How do I know when pork tenderloin is done?

Use an instant-read thermometer in the thickest part. Surface colour and slice colour can be misleading because of the curved shape. 63°C / 145°F internal is the only reliable signal — pull and rest at that temperature.
