Preheat oven to 400 degrees F. Coat a cooling rack with nonstick spray and place on a baking sheet; set aside.
In a large bowl, combine chicken, buttermilk, garlic, basil, oregano, thyme, cayenne pepper, salt and pepper, to taste; marinate for at least 30 minutes. Drain well.
Working in batches, dredge chicken in crushed potato chips, pressing to coat. Place onto the prepared baking sheet; drizzle with butter.
Place into oven and bake, turning pieces halfway through, until crisp and cooked through, about 20-25 minutes.
Serve immediately, garnished with parsley, if desired.
