Air-fried pork tenderloin is a lean, boneless cut seasoned with a simple spice rub and cooked until juicy with a lightly browned exterior. The air fryer cooks it quickly, but tenderloins vary in thickness, so a meat thermometer—not the clock alone—is the reliable way to know when it is done.
Ingredients
- 1 pork tenderloin, about 1 to 1¼ lb (450–570 g), silver skin removed
- 1 tbsp olive oil (15 ml)
- 1 tsp kosher salt (5 g; use about ¾ tsp fine salt)
- 1 tsp smoked paprika (2 g)
- ½ tsp garlic powder (1.5 g)
- ½ tsp onion powder (1 g)
- ¼ tsp ground black pepper (0.5 g)
- 1 tsp Dijon mustard (5 g), optional, for serving
Instructions
- Prepare the tenderloin. Pat the pork dry with paper towels. If a thin, shiny strip of silver skin remains, slide a sharp knife beneath it and trim it away; it can stay tough after cooking. If the tenderloin is longer than the air-fryer basket, cut it crosswise into two pieces so they fit without folding.
- Season it. In a small bowl, mix the salt, paprika, garlic powder, onion powder, and pepper. Rub the pork all over with olive oil, then coat it evenly with the seasoning. Let it sit at room temperature for about 10 minutes while the air fryer heats; do not leave raw pork out longer than 2 hours.
- Preheat the air fryer. Heat it to 400°F (204°C) for 3 minutes, if your model calls for preheating. Set the tenderloin in the basket with space around it so hot air can circulate. Avoid lining the basket in a way that blocks airflow.
- Air fry and turn. Cook at 400°F (204°C) for 10 minutes, turn the pork with tongs, then cook for another 8 to 15 minutes. Start checking the temperature after 18 minutes total. The exact time depends on the tenderloin’s thickness and the air fryer; smaller or thinner pieces cook sooner. If cooking two pieces, check each one separately.
- Check doneness and rest. Insert an instant-read thermometer into the thickest part of the meat, avoiding the basket. USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C), followed by a 3-minute rest. If it has not reached 145°F (63°C), continue cooking in 2- to 3-minute increments and check again. Transfer the pork to a clean cutting board and rest for at least 3 minutes before slicing.
- Slice and serve. Cut across the grain into slices about ½ inch (1.3 cm) thick. Serve plain or with Dijon mustard on the side. The outside may be more browned where it touched the basket, which is normal.
Tips
- Check the label before seasoning. Some tenderloins are injected or enhanced with a salt solution. If yours is, reduce the added salt to about ½ tsp (2.5 g) or adjust to the package information.
- Don’t confuse tenderloin with pork loin. Tenderloin is narrow and cooks quickly; a larger pork loin roast needs different timing. This recipe is for a whole pork tenderloin weighing about 1 to 1¼ lb (450–570 g).
- Use temperature, not color, as your guide. Pork can remain slightly pink at a safe temperature, and color alone cannot confirm doneness. Check the thickest spot with a clean thermometer.
- Make the seasoning your own. If you do not have smoked paprika, use sweet paprika; the flavor will be less smoky. A pinch of cayenne adds heat, while dried thyme or rosemary gives the rub a more herbal flavor.
Serving Suggestions
Pair slices with roasted potatoes, rice, or buttered egg noodles and a green vegetable such as broccoli, green beans, or a crisp salad. For a quick sauce, stir Dijon mustard into pan juices or serve it with applesauce. A simple vinaigrette or lemony slaw also balances the pork’s savory seasoning. If serving with a sauce that contains raw ingredients, keep it separate from the raw-pork preparation area and use clean utensils.
Variations
Maple-mustard: Mix 1 tbsp Dijon mustard (15 g) with 1 tsp maple syrup (5 ml) and brush it over the cooked, rested slices, rather than adding a sugary glaze at the start, which can darken quickly in the air fryer.
Herb and lemon: Add ½ tsp dried thyme (0.5 g) to the rub. Finish the sliced pork with 1 tsp lemon juice (5 ml) and a little finely grated lemon zest.
Chili-cumin: Replace the onion powder with ½ tsp ground cumin (1 g) and add ¼ tsp cayenne (about 0.5 g). Serve with lime wedges and rice or warm tortillas.
Lower-salt rub: Omit the salt and season the cooked slices at the table if needed. The spices still provide flavor, though the meat will taste less seasoned throughout.
Storage and Reheating
Refrigerate cooked pork within 2 hours of cooking, in a covered container or tightly wrapped. It keeps for 3 to 4 days in the refrigerator. For longer storage, freeze sliced or whole portions in a freezer-safe, airtight container for up to 2 to 3 months for best quality; thaw in the refrigerator.
Reheat only the amount you plan to eat. Add a spoonful of water or broth, cover loosely, and warm in the microwave in short intervals, or heat gently in a covered skillet. You can also reheat in the air fryer at 300°F (149°C), checking frequently so the lean meat does not dry out. USDA FSIS guidance is to reheat leftovers to 165°F (74°C), checked with a food thermometer. Cold slices can also be served in sandwiches or salads, provided they have been stored safely.
Frequently Asked Questions
How long does pork tenderloin take in an air fryer?
For a 1- to 1¼-pound (450–570 g) tenderloin at 400°F (204°C), expect about 18 to 25 minutes of cooking, turning once. Thickness, starting temperature, and air-fryer design affect the time, so begin checking at 18 minutes and cook to 145°F (63°C), then rest for 3 minutes.
Do I need to preheat the air fryer?
Preheating for about 3 minutes helps the pork begin cooking evenly, but some air fryers do not require it. If your model’s instructions say not to preheat, follow those directions; the cook time may be a little longer.
Should I wrap pork tenderloin in foil?
No. Cook it uncovered in the basket so hot air can circulate and brown the surface. Foil can obstruct airflow, and a tightly wrapped tenderloin will steam instead of developing a browned exterior.
Can I cook two tenderloins at once?
Yes, if they fit in a single layer with room around each piece. They may need more time if the basket is crowded. Check the thickest part of each tenderloin separately and remove each piece once it reaches 145°F (63°C), followed by a 3-minute rest.
Why is my pork tenderloin dry?
It may have cooked past its target temperature, been sliced before resting, or been cut into especially thin pieces. Use a thermometer, check early, rest it for at least 3 minutes, and slice across the grain. Because tenderloin is lean, it continues to lose moisture if cooked well beyond 145°F (63°C).
Can I season the pork ahead of time?
Yes. Rub the tenderloin with the spices, cover it, and refrigerate for up to 24 hours. Keep raw pork refrigerated at 40°F (4°C) or below, then cook it promptly; do not leave it on the counter to marinate.
