Remove the turkey tenderloins from their packaging and pat them completely dry with paper towels. Removing excess moisture is the secret to getting a nice sear and ensuring the seasoning sticks properly to the meat.
In a small bowl, whisk together the olive oil, salt, pepper, garlic powder, onion powder, thyme, rosemary, and smoked paprika. This creates a thick paste that will coat the turkey evenly and infuse it with classic holiday aromas.
Rub the seasoning mixture all over the turkey tenderloins, making sure to cover all sides. You can do this right before cooking, or let them marinate in the refrigerator for thirty minutes if you have extra time to spare.
Place the seasoned tenderloins in the air fryer basket. Cook at 360 degrees Fahrenheit for 25 to 30 minutes. Around the 15 minute mark, use tongs to flip the tenderloins so they brown evenly on both sides.
Use a meat thermometer to ensure the thickest part of the turkey reaches 165 degrees Fahrenheit. Once done, remove the turkey from the air fryer and let it rest on a cutting board for at least 5 to 10 minutes before slicing. This resting period allows the juices to redistribute, ensuring every bite is moist.
