Begin by unrolling the pre-made croissant dough on a clean, lightly floured surface. Leave it out for about 10 minutes to reach room temperature, and preheat your air fryer to 350°F (175°C).

Place slices of ham on each triangle of dough, and sprinkle a generous amount of shredded cheese on top.

Roll the dough from the wider end towards the tip, tucking in the edges to secure the filling inside.

Beat the egg and brush it generously over the tops of the rolled croissants.

Place the rolled croissants in the preheated air fryer basket, ensuring they’re spaced apart. Cook at 350°F (175°C) for 8-10 minutes, checking for doneness at the 8-minute mark.

Let the croissants cool slightly for about 2-3 minutes before serving.
