In a large bowl, combine the olive oil, garlic powder, onion powder, paprika, cumin, coriander, turmeric, salt, and pepper to create a marinade.
Add the chicken thighs to the bowl and coat them evenly with the marinade. Let it sit for at least 10 minutes to absorb the flavors.
Preheat the air fryer to 200°C (390°F). Place the marinated chicken in the air fryer basket in a single layer and cook for 15-18 minutes, flipping halfway through, until the chicken is golden brown and cooked through.
While the chicken is cooking, prepare the dipping sauce by mixing the yogurt, lemon juice, and minced garlic in a small bowl. Season with salt to taste.
Once cooked, remove the chicken from the air fryer and let it rest for a few minutes. Garnish with fresh parsley and serve with the yogurt dipping sauce.
