Place the chicken down on a parchment paper lined baking sheet. Drizzle them with olive oil and generously season them with salt and pepper. Rub the oil and seasoning evenly onto the meat.
Place them into the center rack of the oven for 40 minutes.
Turn the oven up to 425 degrees and brush the drumsticks with a thick layer of BBQ sauce on all sides. Place them back into the oven for 5 minutes
Spread another thick layer of BBQ sauce on all sides and put them into the oven again for another 5 minutes. Let them cool slightly, serve warm and enjoy!
