Unroll the pre-made croissant dough on a clean surface, allowing it to reach room temperature for approximately 10 minutes.

Place slices of ham evenly on each triangle of dough, then sprinkle a generous amount of shredded cheese over the ham.

Starting at the wider end of each triangle, carefully roll towards the tip, tucking the tips in gently.

Whisk the egg in a small bowl and use a pastry brush to apply a thin layer of egg wash over each rolled croissant.

Set your air fryer to 350°F (175°C) and allow it to preheat for about 5 minutes.

Arrange the croissants in the air fryer basket in a single layer and cook for 8-10 minutes, checking at the halfway mark.

Monitor the croissants closely as they cook, and remove them once they are golden brown.
