This air fryer pork tenderloin is the weeknight dinner hero you didn’t know you needed. It delivers a beautifully seasoned, juicy interior with a subtly crisp, caramelized exterior—all in about 20 minutes of cooking time. The air fryer’s rapid hot air circulation mimics roasting but cuts the time dramatically, making it perfect for a quick yet impressive meal.
Ingredients
- 1 lb (450 g) pork tenderloin (about 1 medium tenderloin)
- 1 tbsp (15 ml) olive oil
- 1 tsp smoked paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp dried thyme
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp cayenne pepper (optional, for heat)
- Fresh parsley, chopped, for garnish (optional)
Instructions
- Pat the pork tenderloin dry with paper towels. Trim off any silver skin (the thin, shiny membrane) and excess fat.
- In a small bowl, mix together the smoked paprika, garlic powder, onion powder, thyme, salt, black pepper, and cayenne (if using). Rub the olive oil all over the tenderloin, then coat evenly with the spice mixture.
- Preheat your air fryer to 400°F (200°C) for 3–5 minutes. If your air fryer doesn’t preheat, just note that cooking time may need an extra minute or two.
- Place the seasoned tenderloin in the air fryer basket. It should fit without touching the sides; if it’s too long, you can tuck the thin end under or cut the tenderloin in half crosswise to fit.
- Cook at 400°F (200°C) for 12–15 minutes, flipping halfway through, until the internal temperature reaches 145°F (63°C) as measured with an instant-read thermometer inserted into the thickest part. This is the USDA FSIS safe minimum for whole cuts of pork.
- Remove the tenderloin from the air fryer and let it rest on a cutting board for 5 minutes. The temperature will rise a few degrees during this time. Slice against the grain and serve.
Tips
- Don’t skip the rest: Resting is non-negotiable for juicy pork. It allows the juices to redistribute; cutting too soon will leave you with dry meat.
- Check early: Air fryer models vary in power. Start checking the temperature at 10 minutes, then continue cooking in 1–2 minute increments until it hits 145°F (63°C).
- Use a thermometer: Visual cues are unreliable for pork tenderloin. An instant-read thermometer is the only way to ensure perfect doneness without overcooking.
- No olive oil? Use avocado or canola oil: Any neutral oil with a high smoke point works. Avoid butter, as it can burn at 400°F (200°C).
Serving Suggestions
Slice the pork and serve it alongside roasted vegetables like asparagus or Brussels sprouts, over a bed of creamy mashed potatoes, or sliced thin on a fresh green salad. It also pairs beautifully with a simple pan sauce made from the drippings, a splash of chicken broth, and a spoonful of Dijon mustard. For a complete meal, add a side of rice pilaf or crusty bread to soak up any juices.
Variations
- Herb-Crusted: Swap the dried thyme for 1 tablespoon of fresh rosemary or sage, finely chopped.
- Sweet & Spicy: Add 1 tablespoon of brown sugar to the spice rub for a caramelized, slightly sweet crust.
- Asian-Inspired: Replace the paprika and thyme with 1 tablespoon of soy sauce, 1 teaspoon of sesame oil, and a pinch of five-spice powder. Skip the salt in the rub.
- Garlic Butter Finish: After cooking, rub the hot tenderloin with a mixture of 2 tablespoons softened butter and 1 minced garlic clove before resting.
Storage and Reheating
Store leftover pork tenderloin in an airtight container in the refrigerator for up to 3–4 days. To reheat, slice the pork and warm it in the air fryer at 350°F (175°C) for 2–3 minutes, or in a skillet over medium heat with a splash of broth to keep it moist. Avoid microwaving, as it can make the pork tough and dry. You can also freeze cooked, sliced pork for up to 2 months; thaw overnight in the fridge before reheating.
Frequently Asked Questions
How long does pork tenderloin take in the air fryer?
At 400°F (200°C), a 1-pound tenderloin typically takes 12–15 minutes. Thicker tenderloins may need up to 18 minutes, while thinner ones might be done in as little as 10. Always rely on a thermometer, not just time.
Do I need to marinate the pork first?
No, this dry rub works beautifully without marinating. The rub adheres to the oiled surface and forms a flavorful crust during cooking. If you have time, you can let the seasoned pork sit in the fridge for 30 minutes to deepen the flavor, but it’s not necessary.
Can I cook a larger tenderloin?
Yes, but you’ll need to adjust the time. For a 1.5–2 lb (680–900 g) tenderloin, increase cooking time to 18–22 minutes, flipping halfway. Make sure it fits in your air fryer basket without crowding; if not, cut it in half crosswise.
Why is my pork tenderloin dry?
Most likely, it was overcooked. Pork tenderloin is very lean and dries out quickly if cooked past 145°F (63°C). Always pull it out at that temperature and let it rest. Also, ensure you’re not cutting it too soon after resting.
Can I use a pork loin instead of a tenderloin?
Pork loin is a larger, leaner cut that is also great in the air fryer, but it requires longer cooking—about 20–25 minutes for a 1.5 lb (680 g) roast. The internal temperature should still reach 145°F (63°C). Note that pork loin is less tender than tenderloin, so slice it thin.
Should I flip the pork during cooking?
Yes, flipping halfway ensures even browning and cooking. If you don’t flip, the bottom may stay pale and the top could burn. Use tongs to carefully turn the tenderloin.
