preheat the oven to 400 degrees Fahrenheit, cover a baking sheet with foil, place a wire rack on the cooking sheet, and spray it lightly with nonstick cooking spray.
Pat the 3 boneless skinless chicken breasts dry, cut them into 1½-inch pieces, and place them in a medium bowl. Sprinkle the chicken with salt and pepper to taste, and pour the ½ cup buttermilk over the chicken. Mix to coat and set aside.
In a shallow dish, combine 1 cup panko breadcrumbs, ½ cup parmesan cheese, and 1 teaspoon Italian seasoning. Mix to combine.
Place 1 cup all-purpose flour, ½ cup melted butter, and 2 lightly beaten room-temperature eggs in separate shallow dishes. There will be 4 dipping dishes in total.
Take the chicken out of the buttermilk over a mesh strainer with a bowl underneath to allow any excess liquid to drip off.
Line up the dipping dishes; flour, butter, eggs, and breadcrumb mixture.
Dredge a chicken piece with flour and shake off any excess. Dip it in the butter, then in the eggs, and finally in the breadcrumb mixture. Place it on the wire rack. Repeat until all chicken has been coated.
Place the prepared baking sheet on the middle rack in the oven and bake for 20-30 minutes, turning after 10-15 minutes. Nuggets are done when golden brown, crispy and cooked through.
If the nuggets aren't as crispy as you want after 30 minutes, Set the oven to broil and cook for a few minutes until desired crispiness.
