Based on my research, I can honestly say that marinating really only adds flavor to the outside of the meat. It doesn't really penetrate the meat to add more flavor, apparently that's more of a myth than anything. Having said that, I still like to marinate these pork chops for about an hour, plus this is great if you want to prep them the night before and when you come home from work the next day, all you need to do is pop them in the oven and you've got dinner.
