Bonne fête! It's Bastille Day again, and this time, its one of my all-time favorites, the croque madame. Over nine years ago, I wrote about the croque monsieur, the classic French ham and cheese sandwich. I go back to that recipe from time to time, and I think it's one of my best from the very earliest period of No Free Lunch. A croque madame is simply a croque monsieur with a fried egg on top, an upgrade in and of itself. My other reason for revisiting the recipe is to improve on the crunchiness by toasting the bread ahead of time. It's definitely worth the effort!
At their core, both a croque monsieur and croque madame are ham and cheese sandwiches, so using good quality ham, cheese, and bread is important. I used Gruyère here, which packs a ton of flavor, but is expensive. It's great as an occasional treat, but feel free to substitute. I shaved the ham off a half boneless ham from Costco and the bread was a peasant loaf from Vermillion's own Mr. Smith's. As with so many things, a fried egg makes everything better. Just make sure to have a knife and fork for this one.
