Air Fryer Beef Tenderloin

1 . Stage

Preheat the air fryer to 400 degrees F (200 degrees C).

2 . Stage

Pat dry tenderloin with paper towels and place on a plate. Drizzle oil all over meat, then sprinkle with oregano, salt, and pepper. Rub spices and oil into meat. Place into the preheated air fryer basket, folding as needed to make it fit. Close the lid.

3 . Stage

Reduce heat to 390 degrees F (198 degrees C) and cook for 22 minutes. Reduce heat to 360 degrees F (182 degrees C) and cook for 10 more minutes. An instant-read thermometer inserted into the center of tenderloin should read 135 degrees F (57 degrees C) for medium doneness.

Remove tenderloin to a platter. Allow to rest, uncovered, for at least 10 minutes before serving.
