01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Place puff pastry sheet on a lightly floured surface.
03 - Set the Brie wheel in the center of the pastry. Spread fig jam evenly over the top of the cheese. Sprinkle with chopped nuts if using.
04 - Fold the corners of the pastry over the Brie, trimming excess if needed, and seal by pinching edges together. Flip the wrapped Brie over so the seams are on the bottom.
05 - Brush the pastry all over with beaten egg for a glossy finish.
06 - Place on the prepared baking sheet and bake for 18–22 minutes, or until the pastry is golden brown and crisp.
07 - Let cool for 5–10 minutes before serving. Garnish with fresh thyme, if desired. Serve warm with crackers or sliced baguette.
