Preheat the oven: Set your oven to 425°F (220°C). A hot oven helps render fat and crisp the skin.
Prep the pan: Line a baking sheet with foil or parchment for easy cleanup. Set a wire rack on top if you have one.
The rack lifts the drumsticks so the heat can circulate.
Pat the chicken dry: Use paper towels to dry each drumstick thoroughly. Dry skin equals better browning and crispness.
Mix the seasoning: In a small bowl, combine salt, pepper, garlic powder, paprika, onion powder, thyme, and red pepper flakes if using.
Coat the chicken: Toss drumsticks with olive oil in a large bowl. Sprinkle the seasoning blend evenly and rub it in so every piece is well coated.
Arrange and bake: Place drumsticks on the rack or directly on the lined sheet, leaving a little space between each.
Bake for 35–45 minutes, depending on size.
Check for doneness: Use an instant-read thermometer. You’re aiming for at least 165°F (74°C) at the thickest part, not touching bone. For extra tenderness, 175–185°F (79–85°C) is great for dark meat.
Optional crisp finish: If you want more color, broil for 2–3 minutes at the end.
Keep a close eye to avoid burning.
Rest and serve: Let the drumsticks rest for 5 minutes. Squeeze lemon over the top and sprinkle with parsley if you like. Serve hot.
