What is a Croque Madame?
A Croque Madame is a French hot ham-and-cheese sandwich topped with an egg. It is closely related to the Croque Monsieur; the egg is the defining addition here.
This version keeps the familiar layers of ham, cheese and béchamel while using gluten-free bread and flour. Mustard gives the creamy sauce a savoury edge, and the egg makes each sandwich a filling centrepiece.

The bread supplies most of the carbohydrates, while butter and Gruyère contribute much of the fat; ham, cheese, milk and eggs provide protein. Pair a sandwich with a green salad or vegetables for a fresh contrast.
Choose the bread and cheese
Bread: Choose slices sturdy enough to hold the fillings and sauce. Gluten-free loaves vary in size and texture, so handle them gently when assembling.
Cheese: Gruyère melts into the sandwich and has a savoury flavour. Check that the cheese and any alternative you use are suitable for your dietary requirements.
Get the béchamel smooth
Flour and butter: Whisk the flour into the melted butter until golden before adding the liquid. This helps form the base of the sauce.
Milk: Add it gradually while whisking to help avoid lumps. Keep whisking until the sauce thickens, then set it aside so it is ready to layer into the sandwiches.
Layer without overfilling
Filling: Divide the ham, Gruyère and béchamel between four slices of bread, then close with the remaining slices. Keep the layers contained so the sandwiches are easier to turn.
Butter: Spread the softened butter over the bread as directed. It helps the outside brown as the sandwiches fry.
Look for a golden finish
Sandwiches: Fry until both sides are golden, then remove them and keep them warm while you cook the eggs. The recipe gives no exact frying time, so use colour as your cue.
Eggs: Cook them in the same skillet to your preferred doneness. A runny yolk can mingle with the sauce, while a firmer egg is easier to eat neatly.
Serve while warm
Finish: Add one egg to each sandwich and scatter over chives, microgreens if using, and freshly cracked black pepper. Serve promptly so the bread and cheese are still warm.
On the side: A simple green salad or lightly dressed vegetables can add freshness alongside the rich sandwich.
Recipe notes & tips
- Whisk continuously as you gradually add the milk to the flour-and-butter mixture.
- Spread the softened butter evenly over the bread for more consistent browning.
- Keep the filling within the edges of the bread to make the sandwiches easier to turn.
- Use the same skillet for the eggs after removing the sandwiches.
- Add the microgreens just before serving so they stay fresh.
Variations
- Add extra mustard: Stir a little more gluten-free Dijon into the béchamel for a sharper flavour.
- Use another melting cheese: Swap the Gruyère for a suitable gluten-free cheese that melts well.
- Add a side salad: Serve with crisp leaves dressed simply for a fresh contrast.
- Change the egg doneness: Fry the eggs until the yolks are as runny or firm as you prefer.
- Skip the microgreens: Leave them off or use extra chopped chives as the garnish.
Common mistakes to avoid
- Lumpy béchamel: Add the milk gradually while whisking steadily.
- Pale sandwiches: Keep frying until both sides are golden before removing them.
- Overfilled bread: Divide the fillings between the sandwiches and keep them inside the edges.
- Cold sandwiches: Keep the fried sandwiches warm while you cook the eggs.
- Overcooked eggs: Watch them closely and remove them when they reach your preferred doneness.
How to store
For the best texture, serve the sandwiches as soon as they are assembled. Refrigerate leftovers in a covered container and reheat in a skillet until warmed through; the bread may soften during storage.
Frequently asked questions
Can I make the béchamel ahead?
The recipe does not specify advance preparation. If you make it ahead, cover and refrigerate it, then warm it gently and whisk before assembling.
How do I keep the sauce smooth?
Whisk the flour into the melted butter first, then add the milk gradually while whisking. Continue until the sauce thickens.
Can I use a different cheese?
Yes. Choose a gluten-free alternative that melts well, as suggested in the ingredient list.
Do the eggs have to be fried in the same skillet?
The method uses the same skillet after the sandwiches are removed. Fry the eggs there to your preferred doneness.
Can I leave out the microgreens?
Yes. They are optional; serve the sandwiches with chives and freshly cracked black pepper instead.
