Serve your vegetable galette warm or room temperature but not hot. Once your galette has finished baking, transfer it on the same parchment paper to a wire rack to cool and help create a crisp crust, not soggy. Cool the galette on the wire rack. If it has cooled completely you can still serve the galette warm, simply preheat the oven to 350°F and reheat it for approximately 10 minutes.
