The time required to bake chicken drumsticks depends on whether the drumsticks are thawed or frozen. Thawed chicken drumsticks should bake at an oven setting of 400 degrees Fahrenheit for 35 to 40 minutes, and frozen drumsticks should bake at 375 degrees Fahrenheit for 55 to 60 minutes.
Ovens vary, so cooking times and temperatures might need to be adjusted to ensure the chicken drumsticks cook completely. According to Tyson Foods, one way to determine if chicken drumsticks are done is when the juice runs clear. Better Homes & Gardens recommends cooking drumsticks until a meat thermometer reads 180 degrees Fahrenheit when inserted into the thickest part of the drumstick.
