- 3
Blanket the onion and cheese mixture with the puff pastry sheet, tucking in the edges if necessary.

Bake in the oven until the puff pastry is golden and crisp.

Carefully flip the tart over so the pastry is on the bottom and the caramelized onions and melty cheese are on top.
- 6
Serve warm as an appetizer.
Notes
The author suggests this as a holiday appetizer. While the specific quantities weren't listed in the transcript, a standard sheet of puff pastry typically serves 6-8 as an appetizer. Ensure onions are pre-caramelized before assembling the tart for the best flavor and texture.
