Yes, it is common to season chicken after marinating. While marinating helps to infuse flavors into the meat, the marinade itself may not be enough to fully season the chicken. Seasoning the chicken after marinating can enhance the overall flavor by adding additional herbs, spices, salt, or pepper. This step is especially important if the marinade is discarded before cooking or if you want to add a more pronounced flavor to the chicken. Remember to adjust the seasoning according to your taste preferences.
