I have developed a brie craving of my own. I made it while in France and now must have it frequently. I use a premade sheet of puff pastry and put it on a baking sheet. I cut thick slices of brie and layer them in the centre. Then I saute sweet onions and mushrooms, drain the liquid and put these on top of the brie. Sometimes I also add some sausage slices. Then I fold the pastry up over it in a circle making a galette with a small opening in the centre. I bake it for 30-40 minutes at 350F and voila!!!
