Preheat oven to 450 degrees. Make sure there's room to fit your roasting pan on a rack. Spray the roasting pan with oil.
Dry the turkey legs with a paper towel. Dip the turkey legs into the melted butter until coated. Season the turkey legs with seasoning. Place the legs into the roasting pan and then into the oven.
Cook the legs for about 20 min or until light brown. Cover the roasting pan loosely with tin foil. Cook to an internal temperature of 165 degrees.
Let the turkey legs rest for 10 minutes while still covered. Then serve.
