Tips for making French onion puffs

1. Use shop-bought frozen puff pastry. Having a few sheets of puff pastry in the freezer is a great tip for the festive season. Whipping up a batch of quick appetizers is a breeze when you are prepared. Thaw the pastry then cut into small squares (approximately 5cmx5cm).
2. Spray a muffin tray with cooking spray then loosely press the puff pastry into each hole.
3. Cook the onions low and slow until they are caramelized and soft. Add the onions to the pastry then add a teaspoon of grated cheese.
4. Pinch the corners of the pastry together to encase the filling then brush with egg wash.
5. Bake until the pastry is puffed, golden and crisp.
6. Remove the puff from the oven and allow to cool for 15-20 minutes before serving.

Making ahead and freezing

These puffs can be made a day in advance and kept un-baked, covered in the fridge. Simply bake before serving. The unbaked puffs can also be wrapped well in plastic and foil and frozen for up to 3 months. Bake from frozen on a parchment-lined baking sheet until crisp and golden.
