Preheat the air fryer to 390 degrees for 5 minutes.
Pat the chicken thighs dry with a paper towel.
In a small bowl, mix together the salt, pepper, garlic powder, onion powder, paprika, and oregano. Rub the seasoning well all over the chicken then transfer to the air fryer, skin side down.
Air fry for 12 minutes, then flip the chicken over and cook for 10-12 minutes more until golden and crispy and cooked through in the center.
