This air fryer pork tenderloin delivers a beautifully caramelized crust with a juicy, tender center every time. It's quick, flavorful, and totally impressive.
In a small bowl, mix together brown sugar, smoked paprika, garlic powder, onion powder, chili powder, salt, and pepper.
Pat the pork tenderloin dry. Rub it all over with olive oil and dijon mustard, then coat generously on all sides with the brown sugar spice rub.
Preheat the air fryer to 400°F (200°C). Place the pork tenderloin in the basket.
Air fry for 18 to 22 minutes, flipping once halfway through, until the outside is deeply caramelized and the internal temperature reaches 145°F (63°C).
Remove from the air fryer and let rest for 5 minutes. The juices will redistribute and the temperature will rise a few more degrees.
