Chicken drumsticks typically take about 35 to 45 minutes to cook in the oven, depending on the temperature used and the size of the drumsticks. Here are common guidelines:

• At 400°F (200°C), bake for approximately 35 to 40 minutes until the internal temperature reaches 165°F (74°C)

• At 425°F (220°C), bake for about 40 minutes, turning once halfway through, until the internal temperature reaches 175°F (79°C)

• At 375°F (190°C), baking may take about 40 to 45 minutes, checking for doneness with a thermometer or by ensuring juices run clear

For best results, use a meat thermometer inserted into the thickest part of the drumstick (avoiding the bone) to confirm an internal temperature of at least 165°F (74°C), which ensures the chicken is safely cooked

. Turning or flipping the drumsticks halfway through cooking helps them brown evenly and achieve crispy skin

. In summary, plan for about 40 minutes at 400–425°F, adjusting slightly by oven and drumstick size, and always verify doneness with a thermometer.
