Preheat your air fryer to 400°F (200°C) for about 5 minutes.
In a mixing bowl, combine olive oil, garlic powder, onion powder, smoked paprika, dried thyme, salt, and black pepper. Mix well to form a marinade.
Pat the chicken thighs dry with paper towels to ensure a crispy skin.
Rub the marinade all over the chicken thighs, ensuring they are coated evenly, including under the skin if possible.
Place the chicken thighs in the air fryer basket, skin side up, ensuring they are not crowded.
Cook the chicken thighs for 25 minutes, flipping them halfway through for even crispiness.
Check the internal temperature of the chicken using a meat thermometer; it should read at least 165°F (75°C).
Once fully cooked, remove the chicken thighs from the air fryer and let them rest for 5 minutes before serving.
