Before getting started, preheat your oven to 375ºF and lightly coat a 13x9 baking sheet with cooking spray.*
Start by whisking the olive oil, salt, pepper and any other seasonings in a large mixing bowl, 'til well combined.
Add your chicken legs to the bowl and toss until well coated with oil and seasonings.
Lay each chicken drum out on the large baking sheet that you prepped in the first step. At this point, you can sprinkle on more seasonings if desired.
Bake your chicken drumsticks at 375ºF for about 20 minutes, and then rotate the tray 180º before baking for another 25 minutes, 'til there's no pink inside and the internal temperature reaches at least 180ºF with a meat thermometer.
Garnish with fresh parsley, if desired, and then serve with all of your favorite side dishes!
