Cut chicken into evenly sized pieces and season with salt and pepper, allowing it to rest briefly for better flavor absorption.
Prepare three bowls: one with seasoned flour mixture, one with whisked eggs and milk, and one with breadcrumbs.
Coat each chicken piece first in flour, then egg mixture, and finally breadcrumbs, pressing gently to adhere.
Heat oil to the correct temperature and test with breadcrumbs to ensure it is ready for frying.
Fry nuggets in small batches until golden brown and fully cooked, then remove and drain excess oil.
Allow nuggets to rest briefly before serving to maintain juiciness and crispiness.
