You could also simmer it in water until it's cooked through and then finish it on the stovetop.
I don't know if it's the correct way or not but this works for me. I put a sausage in a pan on the stove and cover it with a clear (so I can see it) lid. I rotate it every so often so that the outside browns evenly, but the casing remains in tact. Tossing the lid on lets it cook to the desired temperature quicker.
