Lightly sprinkle the chicken legs with salt and pepper. Generously coat the chicken legs with the sour cream.
Put crushed cornflake crumbs in a pie plate or shallow wide bowl and add the Creole seasoning and parsley. Roll the coated chicken pieces in the seasoned crumbs. Place coated chicken in the prepared baking dish. Lightly spray the drumsticks with the vegetable oil.
Bake at 375 degrees for about 1 hour turning as needed or until the meat registers at least 165° F (74° C), the minimum.
