Preheat the oven to 200 degrees Celsius/ 400 degrees Fahrenheit. Line a baking tray with baking paper.
Combine spices: Place 2 tablespoons oil, ½ teaspoon salt, ¼ teaspoon black pepper, and 1 teaspoon sweet paprika powder in a large bowl.
Coat drumsticks: Pat the chicken drumsticks dry with kitchen towels; there is no need to wash the chicken before. Add 6 drumsticks to the spice mixture, coat well, and massage the seasoning into the chicken. Place the chicken drumsticks on the prepared baking tray.
Second spice mixture: Pour the remaining oil, salt, and pepper in the same bowl (no need to clean it before). Add the curry powder and remaining 6 chicken drumsticks, turn to coat with the seasoning, and massage the chicken well with the mixture. Place these drumsticks on the tray as well.
Bake for about 30 to 40 minutes, checking after 30 minutes already. You can use a meat thermometer, in this case, the internal temperature of the chicken should be 75 degrees Celsius/ 165 degrees Fahrenheit.
Or you can check the doneness of the chicken by inserting a skewer or toothpick in the thickest part of the drumstick. The juices should run clea; no pink juices are allowed.
