Heat the oil in a large saucepan or wok at high heat. Stir in the chopped garlic and cook until it is golden brown. Add the Thai chile pepper and stir well.
Add the ground chicken and cook it just halfway done. Reduce the heat to medium and add the mushrooms, fish sauce, oyster sauce, sugar, sweet soy sauce, and chicken stock. Mix well.
When all the ingredients are cooked, add the red bell pepper and the Thai holy basil. Mix well and season to taste with salt. Serve over steamed jasmine rice.
