I always start by preheating my oven to 425°F. While it warms up, I pat the drumsticks dry. Dry chicken helps the skin crisp up beautifully when baked.
In a large bowl, I combine the drumsticks with olive oil, lemon juice, salt, pepper, garlic, and onion powders. Toss everything until the chicken is evenly coated. The olive oil helps all the flavors stick perfectly.
I place the drumsticks in a baking dish, sprinkle chopped rosemary, and dot with butter cubes. Baking for 40-45 minutes makes the chicken tender and juicy. I sometimes broil for 2-3 minutes at the end for extra crispy skin.
Finally, I top the chicken with fresh lemon slices and extra rosemary. This step makes it look as good as it tastes, and the citrus aroma is irresistible.
