Buttermilk ranch, store-bought or homemade, for serving
Method
Preheat the oven to 425°F with a rack in the center position. Line a rimmed sheet pan with parchment paper.
In a food processor, pulse the pecans until as fine as breadcrumbs. Transfer to a shallow bowl or pie pan and stir in the panko, garlic powder, cayenne, and salt until combined.
In a second shallow bowl or pie pan, beat the eggs. In a third shallow bowl or pie pan, place the flour.
Season the chicken all over with salt and pepper. Working with one piece at a time, dip the chicken into the flour and turn to coat. Then dip it into the egg, letting the excess drip off. Then dip it into the pecan mixture, gently pressing to adhere. Arrange the chicken on the prepared sheet pan.
Bake for 20 minutes or until golden brown and the internal temperature of the chicken reaches 165°F on an instant-read thermometer.
Serve the chicken with ranch on the side for dipping.
