Baking chicken legs in the oven at 375 degrees Fahrenheit will take about 30 to 40 minutes. To check that the chicken is cooked properly, insert a skewer into the thickest part of the leg and see that the juices run clear and that the meat is not pink. Alternatively, insert a thermometer and ensure that it reads at least 165 degrees.
The length of time it takes to bake chicken legs is roughly 45 minutes in a 350 degree oven. Be sure and sprinkle some spices such as garlic powder or Mrs/ Dash on them before baking to give them some flavor.
