Start by taking out your puff pastry, and let it stay at room temperature.
Then flatten the puff pastry, as much as you can.
Place the brie cheese in the center of the puff pastry, folding the edges over the Brie cheese.
Place a small piece of aluminum foil into the bottom of the basket, just enough to place the Brie on top of it.
Set your Brie on top of the foil, and set the time for 15 minutes at 375 degrees F.
When it is golden brown, remove from the air fryer.
