Steps
1. In a bowl, mix soy sauce, oyster sauce, sugar, sesame oil, garlic, and ginger to create the marinade.
2. Coat the chicken thighs in the marinade and let them sit for 5 minutes.
3. Heat a skillet over medium-high heat and add the marinated chicken, skin side down. Sear for about 5 minutes until golden brown.
4. Flip the chicken and pour the remaining marinade over it. Cover the skillet and reduce heat to medium-low.
5. Cook for an additional 10-12 minutes, flipping halfway through, until the chicken is cooked through.
6. Serve the chicken over steamed rice, garnished with chopped green onions.
