1. Preheat Oven:
- Preheat your oven to 375°F (190°C).
2. Roll Out Puff Pastry:
- Roll out the puff pastry sheet on a lightly floured surface. If the sheet is not rectangular, shape it into a rectangle.
3. Add Ham and Cheese:
- If desired, spread a thin layer of Dijon mustard over the puff pastry for added flavor.
- Place the ham slices evenly over the puff pastry, leaving a border around the edges.
- Add the Swiss cheese slices on top of the ham.
4. Roll and Cut:
- Starting from one of the longer edges, tightly roll the puff pastry sheet into a log.
- Use a sharp knife to cut the log into 6 equal-sized pieces.
5. Arrange on Baking Sheet:
- Place the cut pieces on a baking sheet lined with parchment paper, leaving space between each one.
6. Brush with Egg Wash:
- Brush the tops of the croissants with the beaten egg. This will give them a golden brown color when baked.
7. Bake:
- Bake in the preheated oven for 15-20 minutes or until the croissants are puffed up and golden brown.
8. Serve:
- Allow the ham and cheese croissants to cool for a few minutes before serving.
9. Enjoy:
- Enjoy your homemade ham and cheese croissants while they are warm and flaky!
