Preheat your Airfryer at 320 F or 160 C for 5 minutes. Brush the sides of the basket with oil.
To coat drumsticks -- Use one hand as it tends to get dirty when dipping the chicken. Take the marinated chicken drumsticks and dunk them well in seasoned flour so that they are coated well. Now dust them lightly to remove excess flour.
Next dip them in beaten egg mix. Your hands will get sticky now.
Take them and rub them in cornflakes and breadcrumbs mix to get a nice thick coating. Keep them aside.
Repeat this method till all drumsticks are ready coated.
Put them in your airfryer basket and put it in the airfryer. My entire batch fitted at one go. Otherwise you can airfry in two batches.
Air fry at 320 F or 160 C for 15 minutes. Open Airfryer half way at 8 minutes and flip the drumsticks once. Be careful while flipping so as to not break the coating.
After 15 minutes increase the temperature to 390 F or 200 C and airfry for 6 minutes more to get a nice golden brown colour.
You could also check the internal temp of chicken which should reach 165 F for it to be cooked.
Your crispy Air fryer fried chicken drumsticks are ready to serve. Serve with onion rings, mint chutney, dip or good old ketchup. Enjoy it hot.
