Prep the chicken: Pat the chicken thighs dry with paper towels.
This helps the skin crisp and the seasoning stick.
Mix the marinade: In a large bowl, whisk olive oil, lemon zest, lemon juice, garlic, oregano, thyme, paprika, cumin, salt, pepper, and red pepper flakes if using.
Coat the thighs: Add chicken to the bowl and toss until every piece is well coated. For best flavor, marinate 20–60 minutes in the fridge. If you’re short on time, a quick 10 minutes still works.
Preheat the air fryer: Set to 380°F (193°C) for 3–5 minutes.
A hot basket helps with browning.
Arrange in basket: Place thighs in a single layer, skin-side down if using skin-on. Avoid crowding; cook in batches if needed.
Air fry first side: Cook at 380°F for 10 minutes.
Flip and finish: Flip thighs (skin-side up now) and cook another 7–10 minutes, until the internal temperature hits 165°F for boneless or 175–185°F for bone-in. Skin should be crisp and lightly charred at the edges.
Rest and garnish: Let rest 3–5 minutes.
Sprinkle with fresh parsley, a squeeze of lemon, and crumbled feta if you like.
Serve: Pair with cucumber-tomato salad, orzo, rice pilaf, roasted potatoes, or warm pita and tzatziki.
