Preheat your oven to 350°F (175°C).
If your brie came in a wooden box, remove it and unwrap the cheese. Place it back in the box (if using) or in a small baking dish.
Score the top of the brie in a crisscross pattern. This helps the jam penetrate the cheese as it bakes.
Spread about 1/4 cup of fig jam over the top of the brie. Don't go overboard – you want a nice balance between cheese and jam.
If you're using additional toppings like nuts or herbs, sprinkle them over the jam now.
For a "naked" brie, simply place it in the oven as is. If you're going for a puff pastry-wrapped version, gently wrap the prepared brie in a sheet of puff pastry before baking.
Bake for 15-20 minutes, or until the cheese is soft and gooey when you touch it.
Let it cool for 5 minutes before serving – trust me, you don't want to burn your tongue on molten cheese!
