In a baking dish, toss the apple slices with butter and maple syrup. Roast in the oven for about 25 minutes until they become tender and caramelized.
Prepare the Puff Pastry
Lay the puff pastry flat on a parchment-lined baking sheet. Place the wheel of brie in the center. Carefully cut away a bit of the rind from the top of the brie, leaving the sides and bottom intact.
Add Sweetness
Spread the apple butter or fig preserves evenly over the exposed top of the brie. Fold the corners of the puff pastry over the brie to enclose it completely.
Egg Wash & Sugar Sprinkle
Brush the pastry with the beaten egg to give it a golden finish, then sprinkle lightly with coarse sugar.
Bake the Brie
Bake for 20-25 minutes or until the puff pastry is golden and crisp.
Finish with Apples
Remove from the oven and spoon the roasted apples over the baked brie. Garnish with fresh thyme for a touch of herbal aroma.
Serve
Enjoy this decadent dish with crackers or simply dive in with a spoon for a warm, gooey delight.
