Place the chicken parts in a shallow dish, whisk together the buttermilk and pepper, pour over the chicken. Set aside.
Next we’re going to set up our assembly line. In a container with a tight fitting lid add the flour, salt, and pepper. Give this a good shake (with the lid on!) and set aside. Next, in a microwave safe shallow dish add the olive oil and butter, microwave just long enough to melt the butter, it took between 20 – 30 seconds in my microwave. Set next to the flour container. In another lidded container place the final three ingredients, close the lid and give it a good shake. Grab a baking sheet and line it with foil. Normally I’m all about a little olive oil or cooking spray, but humor me. If you are completely texture oriented and need the chicken as crispy as humanly possible get a baking rack to place over the sheet.
Preheat the oven to 375°F.
Find something to do for 5 minutes or so. Go wild, plan a side dish.
Starting with the smallest pieces: wings, drumsticks, thighs, then breasts, place one or two pieces in the flour container and give it a good shake. One at a time, remove the pieces from the flour, shaking off any excess, and dip in the oil / butter mixture. Shake the pieces again and add to the final container, giving a good shake to coat the piece evenly. Place on the baking sheet or rack.
Once all of the pieces have moved through your assembly line place in the oven for 40 – 60 minutes. Use a meat thermometer to ensure the largest pieces have reached 165°F If using a whole chicken it may be necessary to cook the breasts longer than the wings and drumsticks, simply set them aside on a paper towel. If the coating on larger pieces looks as though it may brown too quickly, use a small piece of foil as a tent to shield the coating.
