Instructions:

1. Preheat the Oven:
Preheat your oven to 200°C (392°F).
2. Prepare the Onions:
- In a medium skillet, heat the olive oil over medium heat.
- Add the sliced red onions and cook, stirring occasionally, until they are soft and caramelized, about 10-15 minutes.
- Tip: If the onions start to brown too quickly, reduce the heat slightly.
3. Prepare the Sweet Potatoes:
- While the onions cook, peel the sweet potatoes and slice them thinly, about 1/8-inch thick.
- In a bowl, toss the sweet potato slices with the chopped rosemary to evenly coat.
4. Prepare the Puff Pastry:
- Roll out one sheet of puff pastry on a lightly floured surface to fit a pie dish or baking tray. Ensure that there’s some overhang to form the edges.
- Place this sheet of puff pastry into the pie dish or onto the baking tray.
5. Assemble the Pie:
- Evenly spread the caramelized onions over the bottom of the puff pastry.
- Arrange the sweet potato slices on top of the onions in a circular pattern, overlapping slightly.
- Sprinkle the grated cheddar cheese over the sweet potatoes.
6. Top the Pie:
- Roll out the second sheet of puff pastry to cover the pie.
- Place this sheet over the filling and tuck the edges into the dish or pinch to seal.
- Note: If you want a decorative edge, use a fork to press down the edges.
7. Egg Wash:
- Brush the top of the pie with the beaten egg. This will give the pastry a golden, glossy finish.
8. Bake:
- Place the pie in the preheated oven and bake for 25-30 minutes, or until the pastry is golden brown and puffed up.
- Tip: If the edges brown too quickly, cover them with aluminum foil.
9. Cool and Serve:
- Allow the pie to cool slightly before slicing. Serve warm and enjoy!
