Prep the drumsticks: Pat the chicken dry with paper towels. Dry skin means better browning and crispiness.
Make the spice rub: In a small bowl, mix salt, pepper, cumin, coriander, paprika, turmeric, chili powder, garam masala, garlic powder, onion powder, and ginger.
Stir in the oil and lemon juice to form a thick paste. Add brown sugar or honey if using.
Coat the chicken: Add drumsticks to a large bowl. Spoon the spice paste over them and rub it in with your hands until every piece is evenly coated, including under the skin where possible.
Preheat the air fryer: Set to 380°F (193°C) for 3 minutes.
A warm basket helps the skin start crisping right away.
Arrange in the basket: Place drumsticks in a single layer with a little space between them. Do not overcrowd. Work in batches if needed.
Air fry, then flip: Cook at 380°F (193°C) for 12 minutes. Flip the drumsticks and cook for another 10–12 minutes.
Check for doneness: Internal temperature should reach 165°F (74°C) at the thickest part, not touching bone.
If not there, cook 2–4 minutes more.
Crisp finish (optional): For extra char, increase to 400°F (204°C) for the last 2–3 minutes.
Rest and serve: Let the chicken rest 3–5 minutes. Squeeze with lemon, sprinkle cilantro, and serve with the yogurt sauce if you like.
