In an empty plate, pour oil and mix everything bagel seasoning together.
Coat the drumstick in the mix. Sprinkle additional seasoning if needed. Then place it in a baking pan.
Bake the drumsticks at 425 for about 20 minutes. If you are interested in baking some veggies like brussels sprouts, add it after the 20 minutes. Otherwise, you can bake it for 45 minutes.
After 20 minutes, place the sliced brussels sprouts in the baking pan. Turn the drumsticks to ensure the other side is baked. If you are not adding veggies, that is cool too. But make sure the drumsticks are turned.
