Make the béchamel: In a saucepan over medium heat, melt the butter. Add the flour, whisking quickly to form a roux. Slowly pour in the milk while continuing to whisk to prevent lumps. Let simmer for about until the béchamel thickens. Season with the nutmeg, salt and pepper. Set aside.

On two slices of sandwich bread, spread a tablespoon of béchamel on each side. Place a slice of ham and a handful of shredded cheese on the béchamel of one of the slices, then close the sandwich with the other slice of sandwich bread.
Preheat your air fryer to 350 °F for .
Place one or two croque-monsieurs (depending on the size of your appliance) in the air fryer basket. Be sure not to stack them for even cooking.
Start cooking for at 350 °F. Halfway through (after ), gently flip the croque-monsieurs so they brown evenly on both sides and the cheese melts perfectly.
Repeat for the remaining croque-monsieurs if needed.
Once the croque-monsieurs are cooked, the bread should be golden and crispy, and the cheese well melted. Cut them diagonally to get two triangles. Serve hot and enjoy right away!

For an even more indulgent, golden croque-monsieur, you can lightly brush the outer slices of sandwich bread with a little melted butter before placing them in the air fryer. This will help give you a nicely crisp crust and an appetizing color. Don't overcrowd your air fryer basket for the best results.
