A Croque Madame is, basically, an open-faced sandwich. A bit of sliced ham, a freshly fried egg, some tasty sauce…and you have a quick meal. In this gluten-free version, you simply use GF bread as the base of your sandwich.
Traditionally, this sandwich is made with ham. I actually prefer to use thinly sliced turkey when I’m in the mood for a lighter, less salty taste. Of course, once you have the basics down, you can play with the ingredients to suit your needs.
One other note: traditionally, a bechamel sauce is used. I prefer using a tangy substitute to save time.
