Making Southern style chicken in the oven
Try raising the chicken above the roasting pan, with something like a grill grate or roasting rack. Having air flow to the bottom of the chicken pieces will help crisp up the batter on that surface, and the surface area of anything that can stick to your chicken will be limited as well. You will also want to use very high heat (~450F) when cooking, so that the batter will get to the proper texture.
