Roll the puff pastry sheet into a rectangle that is at least 8 inches wide and no less than ⅛-inch thick. With the standard puff pastry sheets found in the grocery stores, you won't have much rolling to do.
Spread mango chutney over the puff pastry and top with cheddar cheese. Using a rolling pin, lightly press the cheese into the pastry. Roll each long end of the rectangle into the center. Chill for about 15 minutes.
Cut the roll crosswise into ⅛-inch slices and divide the palmiers between two baking sheets covered with parchment paper. Chill for at least 1 hour.
Preheat the oven to 450 degrees F. Bake the palmier until they are puffed and light golden brown, 6 to 8 minutes. Quickly flip the palmiers and place back in the oven, switching positions of the baking sheets. Bake for an additional 4 to 5 minutes. Transfer the palmiers to a cooling rack and cool completely before serving.
Make ahead: The palmiers can be baked and then store in the fridge in an airtight container for 2 to 3 days, or frozen. Before serving, place unthawed palmiers on a baking sheet in a 350 degree F oven for 5 minutes.
