Preheat the oven to 350' and grease a shallow, ovenproof baking dish.
Steam the brussels for 4 minutes, drain and let them cool to the touch.
Mix together the cream, dijon, creme fraiche if using, salt, and pepper.
Chop up the sprouts and tip them into the prepared dish.
Pour the cream mixture over the top.
Sprinkle the parmesan over the top and bake them for 15 minutes, turning the broiler on for an extra minute or two at the end to brown the top.
Garnish with fresh parsley. Enjoy warm.
