1
Mix spices together in a small sealable bag. Add 1 tablespoon spices, buttermilk and chicken to a large freezer bag and marinate 6-24 hours. Store remaining spices.
2
Preheat oven to 400 degrees F. Line a rimmed baking tray with parchment paper (foil will NOT work because the chicken sticks to it). Add butter to baking tray and melt in oven while it preheats. Remove baking tray once butter is melted.
3
Mix together flour, panko, cornmeal and remaining spices in a large bowl. Add half of this breading mixture to a large freezer bag.
4
Remove chicken from buttermilk and dab off excess marinade with paper towels.
5
Add half of the chicken to the breadcrumb bag and shake until well coated, pressing the breadcrumbs into the chicken with your fingers through the bag. Lay breaded chicken in butter on baking tray. Add remaining breadcrumb mixture to bag along with remaining chicken and repeat.
6
Bake at 400 degrees F for 10-12 minutes until golden then carefully flip chicken and bake another 5 minutes then broil to desired crispiness. (If the breading is white in some places after you flip your chicken, this simply means it did not come in contact with the butter.)
