Baked pork chops for two

I tried the recipe for pork chops baked with wild mushrooms and crème fraîche. Unfortunately, it came out very dry and a little overcooked. I cooked them in an electric Aga which does sometimes seem to cook hotter than the temperature. Also, I cooked only two chops (with the other ingredients reduced proportionately). If it were in a microwave, of course, I'd expect to reduce the cooking time but I didn't think that would be necessary in an oven. Can you give any advice because it was a simple dish to prepare (always my favourite sort) and I'd like to do it again? (One other thing: I may not have cooked the mushrooms enough so I may have started with less liquid from them.) Thank you.
