In a small bowl, mix together salt, dried parsley, dried oregano, black pepper, onion powder, garlic powder, and olive oil to create a marinade.
Place the chicken thighs in a large bowl or resealable plastic bag and coat them evenly with the marinade. Let them marinate in the refrigerator for at least 1 hour, or up to overnight for maximum flavor.
Preheat your air fryer to 380°F (190°C) for about 3-5 minutes.
Remove the chicken thighs from the marinade and shake off any excess marinade.
Place the chicken thighs in the air fryer basket, skin side down, in a single layer. You may need to cook them in batches depending on the size of your air fryer.
Cook chicken thighs in the air fryer at 380°F (190°C) for 12 minutes.
After 12 minutes, flip the chicken thighs over using tongs and cook for an additional 10 minutes, or until the internal temperature reaches 165°F (74°C) and the skin is crispy and golden brown.
Once cooked, remove the chicken thighs from the air fryer and let them rest for a few minutes before serving.
Garnish with fresh herbs if desired, and serve hot with your favorite side dishes.
