By the time you have made a croque-monsieur, turning it into a croque-madame is one of the simplest and fastest things you’ll do. The upgrade is the more complete version of the sandwich. It contains proteins from lots of sources: milk, cheese, ham, bread, and an egg.
The croque-monsieur and this variation both rely on having a base béchamel sauce to coat the bread.
My personal taste is to go for the croque-madame whenever possible. The flavor of the egg white and yolk combines well with the rest of the sandwich, which is itself already a declaration of indulgence. If I am going to indulge, might as well really do so.
