In a large skillet or frying pan, heat the neutral oil over medium-high heat. Once the oil is hot, add the chicken thighs. Cook the thighs for about 4-5 minutes on each side or until they are nicely browned. Remove the chicken thighs from the skillet and set aside.
In the same skillet, add the halved garlic. Cook until browned and set aside.
Cover the crock pot with its lid. Set it to low and let it cook for 6-7 hours. Alternatively, if you're pressed for time, you can set it on high for 3-4 hours.
Once done, carefully remove the chicken thighs and place them on a serving dish. Drizzle some of the cooking sauce from the crock pot over the chicken. Garnish with sliced scallions. Serve with steamed rice, noodles, or your preferred side.
