Preheat your oven to 400°F (200°C). Line a baking tray with parchment paper.
Pat the drumsticks dry with paper towels. Toss with olive oil, salt, and pepper until evenly coated.
10–12 chicken drumsticks, Salt and black pepper, 2 tablespoons olive oil
Arrange the drumsticks on the prepared tray in a single layer. Bake for 25–30 minutes, turning halfway through.
In a small bowl, mix the barbecue sauce and apple cider vinegar. Brush the sauce over the drumsticks.
1 cup barbecue sauce, 2 tablespoons apple cider vinegar
Return to the oven and bake for another 15–20 minutes, turning and brushing with more sauce halfway through, until fully cooked (internal temperature should reach 165°F / 74°C). For a sticky, caramelized glaze, broil for 2–3 minutes at the end.
Garnish with fresh parsley and serve warm.
