Croque Madame
A croque madame is a French hot sandwich built from grilled bread, ham, Gruyère cheese, and béchamel sauce, then topped with a fried egg. It's essentially a croque monsieur with an egg on top, and the name comes from the way the egg resembles a woman's hat. The bread is usually pain de mie or a firm white sandwich loaf, buttered and either pan-fried or broiled so the outside crisps while the cheese and béchamel melt through the inside.
Varieties
A croque monsieur is the same sandwich without the fried egg on top. Some versions swap béchamel for a simple layer of Dijon mustard and extra cheese, which produces a sharper, less creamy result.
Buying tips
Buy Gruyère from the deli counter and ask for it sliced or grate it yourself; pre-shredded bags often contain anti-caking starch that keeps the melt from going as smooth. Choose a thick-cut, unsmoked ham (jambon blanc style) rather than deli lunch meat for a more authentic result.
Substitutes
White American or Swiss cheese (in place of Gruyère) — 1:1 by weight
Melts just as well and gives a similar creamy pull, though it lacks Gruyère's nutty, slightly funky depth.
Store-bought Alfredo sauce (in place of béchamel) — 1:1 by volume
Already thickened with cream and cheese, so it stands in for béchamel with almost no adjustment, just thin it slightly with milk if it's very thick.
Turkey or roast beef (in place of ham) — 1:1 by weight
Changes the flavor profile noticeably, but keeps the sandwich's basic hot, layered structure intact.
Sourdough or brioche (in place of pain de mie) — 1:1, same slice thickness
Sourdough adds tang and a sturdier crust; brioche adds sweetness and browns faster, so watch it closely under the broiler.
Storage
Croque madame is best eaten immediately while the egg yolk is still runny and the bread is crisp. If leftovers happen, store the sandwich without the egg in an airtight container in the refrigerator for up to 2 days, and fry a fresh egg when reheating.
How to use
Serve as a bistro-style lunch or brunch main with a simple green salad dressed in vinaigrette to cut the richness. It's also a good way to use up leftover holiday ham and stale sandwich bread that needs a second life.
What it pairs with
Pairs well with a dry white wine like Muscadet or a crisp cider, and with a lightly dressed frisée or arugula salad to balance the richness of the béchamel and fried egg.
Nutrition
A single croque madame typically runs 500 to 700 calories depending on cheese and bread quantity, with significant saturated fat from the butter, cheese, and béchamel, plus a notable protein boost from the ham and egg.
FAQ
What's the difference between a croque madame and a croque monsieur?
They're the same sandwich, but a croque madame is topped with a fried egg while a croque monsieur is not.
Can I make croque madame without béchamel?
Yes. Spread a thin layer of Dijon mustard and use extra shredded Gruyère on top instead; it won't be as rich but still melts and browns well under the broiler.
Why does the bread get soggy in the middle?
Too much béchamel or an under-toasted first side is usually the cause. Toast the bread lightly before assembling and use a thin, spreadable layer of sauce rather than pouring it on.
Can croque madame be made ahead for a brunch crowd?
Assemble the sandwiches without the egg up to a few hours ahead and refrigerate, then broil until melted and top each with a freshly fried egg right before serving.
