1In a bowl, mix Greek yogurt with paprika, red pepper flakes, dried herbs, minced garlic, lemon juice, olive oil, salt, and pepper. Stir well.
2Place chicken thighs in a large bowl or zip-top bag, pour the marinade over them, and ensure each piece is well coated. Cover and refrigerate for at least 30 minutes (or up to 24 hours for deeper flavor).
3Preheat the air fryer to 170°C (340°F).
4Arrange chicken thighs in the air fryer basket skin-side up, without overlapping. Cook for 20 minutes, then carefully flip each thigh and cook for another 10 minutes, until the skin is golden and crispy and the internal temperature reaches 74°C (165°F).
5Serve immediately with your choice of side: rice, salad, or roasted potatoes.
