Croque Madame

Melt 1 tablespoon of butter in a pan and stir in the flour, cooking over low heat for 1 minute.

~1 min

Gradually whisk in the milk to make a thick béchamel sauce, then season with salt, pepper, and nutmeg.

~5 min

Why: Adding the milk gradually instead of all at once is what keeps the sauce smooth and lump-free.

Spread Dijon mustard thinly over 2 slices of bread.

~1 min

Layer the ham and cheese on the bread, then top with the remaining slices.

~2 min

Spread béchamel sauce over the outside of the sandwich, sprinkle with the remaining cheese, and toast in a pan or oven until golden.

~4 min

Watch out: A too-thick layer of sauce leaves the inside soggy — spread it in a thin, even layer.

In another pan, melt butter and fry the eggs sunny-side up with a runny yolk.

~2 min

Top the toasted sandwich with the fried egg to finish.
