Cooking stuffing inside a turkey is discouraged due to food safety concerns and the risk of uneven cooking. When stuffing is placed inside the turkey cavity, it takes longer to reach a safe temperature for consumption. As a result, the turkey's outer meat may overcook and become dry before the stuffing reaches a safe temperature, creating a potential health hazard. Furthermore, the moist environment inside the turkey can promote the growth of harmful bacteria in the stuffing, posing a food safety risk. It's safer to cook stuffing separately in a baking dish, allowing it to reach a safe internal temperature and ensuring both the turkey and stuffing are cooked to perfection while reducing the risk of foodborne illness.
