Preheat air fryer to 400 degrees (or as high as your air fryer will go.)
In a small bowl, add oil, herbs, and spices, mix well.
Drizzle over chicken thighs, toss to coat.
Chicken can be marinated overnight, but this is optional.
Add chicken thighs to air fryer basket.
Air fry at 400 for 8 minutes.
Flip thighs, cook another 8 minutes.
Using a digital thermometer, probe the thickest part of the chicken thigh's meat, taking care to not hit the bone.
You will likely need to flip chicken thighs once more and cook an additional 4-6 minutes to reach 165 internal temperature, but be sure to go off your thermometer, not the cooking time on your air fryer!
If you used skin-on chicken, and your chicken skin is not crispy, crunchy, and golden brown, pop directly under your air fryer's broiler or your oven's broiler to crisp for 1-2 minutes.
Remove from air fryer, and let sit for at least five minutes before serving.
Notes
To cook chicken thighs with bone-in, you may need to add an additional 2-4 minutes to cook time. Please watch internal temperature and be sure to not get thermometer too close to chicken bone to get an accurate reading.
