Add flour and spices to a bowl and mix to combine. You can coat chicken in the bowl by hand, or you can transfer the seasoning blend into a large zippered bag (or reusable bag), seal, and shake the chicken inside to fully coat.
Place seasoned chicken evenly spaced on your baking sheet. Drizzle generously with olive oil on each piece.
Bake for 50 minutes, flipping drumsticks halfway through.
Serve immediately or refrigerate (great for meal prepping) for about 4 days, or 6 months in freezer.
