Pat the pork tenderloin dry with a paper towel. Pour the olive oil over the roast and rub all over until completely covered.
Add the brown sugar, salt, garlic powder, and black pepper to a small bowl. Stir until combined.
Cover the pork loin with the spices.
Place the pork in the air fryer basket.
Cook in the air fryer at 380°F/190°C for 10 minutes. Flip the roast over and cook for an additional 8-10 minutes, or until the pork reaches an internal temperature of 145°F/63°C.
Let the roast rest for 5 minutes before slicing.

Notes
Pork tenderloin is done when the pork reaches an internal temperature of 145F.
If your post tenderloin is too long for your air fryer basket, you can cut it in half so you have two pieces side by side.
If your pork tenderloin is smaller or larger than 1.5 lbs you may need less or more time than the recipe states.
The spice mixture is a suggestion, but you can use any spice blend that you prefer to change the flavor of the pork tenderloin.
Pro Tip: This recipe can be made in the air fryer unit with a basket or the air fryer oven. If you are using the air fryer oven, use the middle rack and select the "Air Fry" function.
Pro Tip: Check your food as it cooks. Each air fryer runs a bit differently. Sometimes airfying is a trial and error process. Check your food as it cooks to learn your air fryer better! When cooking a new recipe or food items be sure to check your food often to help avoid over/under cooking.
