Heat oven to 400°F. Cover a rimmed cooking sheet with foil and spray the foil with nonstick cooking spray. Place a wire rack on the cooking sheet, and spray it lightly with nonstick cooking spray.
Pat the chicken dry, cut it into 1½-inch pieces and place it in a medium bowl. Sprinkle the chicken with ½ teaspoon salt, ½ teaspoon freshly ground black pepper, and add the buttermilk. Mix to coat all the chicken pieces. Set aside.
In a shallow dish, combine breadcrumbs, parmesan, and herbs. Mix to combine.
Place flour, butter, and eggs in separate shallow dishes. There will be 4 dipping dishes in total.
Strain the chicken/buttermilk over a mesh strainer with a bowl underneath.
Line up the dipping dishes; chicken, flour, butter/egg mixture, breadcrumb mixture.
Dredge a chicken piece with flour and shake off any excess. Dip it in the butter/egg mixture and then the breadcrumb mixture. Place it on the wire rack. Repeat until all chicken has been coated.
Place cooking sheet on the middle rack in the oven. Bake 20 to 30 minutes, turning after 10 to 15 minutes. Nuggets are done when golden brown, crispy, and cooked through.
If nuggets aren't as crispy as you want after 30 minutes, set the oven to broil and cook a few minutes until desired crispiness. Serve hot with dipping sauces. Enjoy!
