In a small bowl combine paprika, granulated garlic, onion powder, chili powder, thyme, salt, pepper, and cayenne pepper and mix until combined.
Add half of the spice mixture into the buttermilk and mix until combined.
Place your chicken pieces into a bowl and pour the seasoned buttermilk over the top and toss until combined. Marinade for 12-24 hours.
Preheat the oven to 400 degrees and place a baking sheet in the oven to get hot. In another shallow bowl add the bread crumbs, flour, and remaining spice mixture and whisk until combined.
Remove the chicken from the buttermilk and shake off any excess and dip into the egg mixture, then into the breading mixture, and place on a plate or platter. Repeat until all of the chicken is coated.
When the oven is ready remove the baking sheet and spray with nonstick cooking spray or rub 1 tablespoon of butter on the sheet.
Place the chicken on the hot baking sheet, skin side down. Spray the top of each chicken piece with nonstick cooking spray, this is optional but I find it helps crisp up the skin.
Bake for 15 minutes then flip and bake for another 20 minutes or until internal temperature reaches 164 degrees.
Remove from the oven and let rest for 5 minutes and serve!
