Prepare Rice: Wash 2 cups of short grain rice three times and soak in cold water for at least 30 minutes.
Prepare Seasoned Water: Mix 2 cups of water with 1/2 tablespoon chicken bouillon powder (or chicken stock and salt) for flavor.
Marinate Chicken: In a bowl, combine 1 pound boneless skin-on chicken thighs with 2 1/2 tbsp soy sauce, 1 tbsp oyster sauce, 1/2 tbsp honey, 1 tbsp mirin, 1 tbsp garlic powder, 1/2 tbsp neutral oil, 1/2 tbsp toasted sesame oil, and black pepper. Massage well and set aside.
Prepare Vegetables: Smash and finely chop 6 garlic cloves. Dice half an onion. Thinly slice 5 green onions, separating whites and greens.
Sear Chicken: Heat 2 tablespoons oil in a large pot over medium-high heat. Place marinated chicken skin-side down and sear for about 2 minutes until light golden brown. Flip and cook the other side for about 3 minutes. Remove chicken and set aside.
Sauté Aromatics: In the same pot over medium heat, add garlic, onion, and white parts of green onions. Sauté for about 2 minutes. Add more oil or butter if needed.
Cook Rice with Aromatics: Add drained rice to the pot and stir for about 1 minute until well coated with aromatic oil.
Add Seasoned Water and Simmer: Pour in the seasoned water, scraping up any browned bits from the pot. Bring to a boil, then reduce heat to low. Add chicken back in, cover with lid, and simmer for 15 minutes.
Steam Rice: Remove pot from heat and let it steam, covered, for another 10 minutes.
Final Touches: Remove chicken, add a pat of butter and green onion greens to the rice, and mix. Optionally, add chicken back with a few shishito peppers and steam for 5 more minutes for extra fragrance.
