Melt 10 g of butter in the saucepan over medium heat, add the 15 g of flour and stir for 1 minute with the whisk. Pour in the 15 cl of milk a little at a time, whisking nonstop.
Tip · Whisk without stopping when you add the milk, and pour it in a thin stream: that's what keeps lumps away.
Thicken and season
Let it cook over low heat, stirring, until the sauce coats the spoon. Add the pinch of nutmeg, salt and pepper, then, off the heat, half the shredded cheese (50 g).
Fill the bread
Use 8 slices of sandwich bread: spread the béchamel on 4 slices. Lay the ham (150 g) over those 4 slices, then top with the other 4 slices.
Sear the first side
Melt half the remaining butter (7 g) in the skillet over medium heat. Lay in 2 croque-monsieurs and brown them for 3 minutes.
Flip and add the cheese
Flip the croque-monsieurs, sprinkle half the remaining cheese (25 g) on top and let them brown for 3 minutes over medium-low heat, with a lid or a plate on top so it melts.
Tip · Keep the heat at medium-low so the bread browns without burning before the cheese melts. Serve with a green salad.
Cook the second batch
Take out the first 2 croque-monsieurs and keep them warm on the plate. Melt the remaining butter (8 g) and do the same thing with the other 2 and the remaining cheese (25 g).
Serve right away
Cut each croque-monsieur in half and serve them piping hot, with the cheese still gooey.
And there you go, it's readyCheck off every step to celebrate.

Pantry salt, oil and spices aren't counted. Your store and your brands will move the total, but the ballpark is right.
How long does it keep?
Eat it fresh. Bread and wraps get soggy when they sit with the filling. Prep the filling ahead if you want, and put it together the day you eat it!
