Preheat oven to 400°.
Wash potatoes, spear a few times with a fork, and bake for one hour or until you can easily insert a fork into the potato.
Remove potatoes from oven and let cool, slightly.
Mix together the crème fraîche and the fresh herbs in a small bowl.
Cut a large oval in the top of each potato and remove the "oval" skin.
Using a tablespoon, remove the inside of the potato, leaving the skin intact.
Put in a medium bowl and mash (using a hand potato masher).
Add all of the rest of the ingredients, including the crème and herbs, and mash until you achieve your desired consistency. Add more milk if you want less dense potatoes.
Put potato mixture back in the potato shell and top each potato with a little more grated cheese.
These potatoes can be made earlier in the day and refrigerated. Take the potatoes out of the refrigerator about 30 minutes before baking. Bake at 350℉ for 40 minutes.
