Preheat your oven to 425°F (220°C) and place a wire rack on a baking sheet. Cover the baking sheet with aluminum foil and lightly coat the rack with cooking spray.
In a mixing bowl, combine olive oil, salt, pepper, paprika, garlic powder, onion powder, thyme, oregano, and cayenne pepper. Mix until you have a flavorful seasoning blend.
Pat the drumsticks dry with paper towels and then brush each one with the seasoning mixture, ensuring they're evenly coated.
Arrange the drumsticks on the prepared wire rack, leaving some space between each to allow for even cooking.
Bake in the preheated oven for 45-50 minutes, or until the drumsticks are golden brown and cooked through. Make sure the internal temperature of the chicken reaches 165°F (74°C).
Once they're done, let them rest for a few minutes before serving. The result? Crispy, juicy, and incredibly delicious oven-baked drumsticks!
