Preheat your oven to 425°F. Line a baking sheet with parchment paper and place a wire rack on top.
In a large bowl, combine the buttermilk, garlic powder, onion powder, smoked paprika, salt, and black pepper. Add the chicken thighs and ensure they are fully submerged. Cover and refrigerate for at least 1 hour, or overnight for best results.
In a shallow dish, mix the flour and panko breadcrumbs together. Remove the chicken from the buttermilk mixture, allowing excess to drip off, then dredge each piece in the flour and panko mixture, pressing gently to adhere.
Place the coated chicken on the wire rack. Drizzle the olive oil over the chicken pieces to help them crisp up in the oven.
Bake for 35-40 minutes, or until the chicken is golden brown and reaches an internal temperature of 165°F. In the last 5 minutes of baking, brush the hot honey over the chicken for a sticky, sweet finish.
Remove from the oven and let rest for 5 minutes. Garnish with chopped parsley before serving.
