Marinate the chicken: Combine soy sauce, dark soy sauce, oyster sauce, honey, sugar, garlic, five-spice powder, and white pepper in a bowl. Add the chicken and coat them thoroughly in the marinade. Marinate for at least 30 minutes, or overnight for better flavor.
Cook the chicken: Air fryer method: Place the chicken in the air fryer, skin side facing up. Cook at 380°F (190°C) for 20 minutes, or until the internal temperature reaches 165°F (74°C). Oven method: Place the chicken on a baking sheet, skin side facing up. Bake at 420°F (220°C) for 25 minutes, or until the internal temperature reaches 165°F (74°C). Stovetop method: Heat oil in a pan over medium-high heat. Sear the chicken thighs, skin side down, for 2 minutes. Flip the chicken and sear for another 2 minutes. Pour in the marinade and reduce heat to low-medium. Cover and simmer for 7 minutes. Flip the chicken, cover, and simmer for another 7 minutes. Flip again so the skin is up and baste with the sauce.
Serve: Garnish with green onions and sesame seeds (optional). Serve with rice and vegetables.
