Croque M
There are countless versions of croque monsieurs and croque madames all over France. My mom cooks the sandwiches in a cast-iron press on the stovetop so that the bread becomes a crisp casing for the filling. I prefer a sandwich that’s hot and moist all the way through, so I bake the cheese on top of the bread and spread béchamel throughout. That’s the key to my version: The bread must completely absorb the sauce. The effort is well worth it.
