In a large bowl, marinate the chicken fillets with the minced garlic, five-spice powder, white pepper, oyster sauce, soy sauce, 1 egg and cornstarch for 20 minutes.
In another bowl, combine the all-purpose flour, cornstarch, garlic powder, paprika and five-spice powder.
Dip the chicken into the flour mixture, coating it well. Shake off any excess flour.
In a large pot, add about 7 cm of oil and heat over medium-high until it reaches roughly 180 °C.
Add the chicken and fry for 6–7 minutes or until crispy and golden.
