Buttermilk lends a tanginess to chicken and tenderizes it, which will add to the moistness. Adding fresh herbs to the buttermilk will help infuse a little extra flavor into the flesh.
- Place the chicken in a freezer bag and pour 1 quart buttermilk over it, covering all parts. Seal and place in baking dish in the refrigerator for 4 hours, turning every hour.
- Preheat oven to 425 degrees. Drain buttermilk and discard.
- Mix the rest of the ingredients together. Place the chicken in a cast iron skillet. Paint with oil and herb mixture.
- Place in preheated oven for 45 minutes−1 hour, or until juices run clear. Remove from oven and allow to rest 15 minutes before cutting.
