First of all, prepare the béchamel: melt the butter with the flour to prepare a roux, then dilute it with warm milk, mixing well.
Add a pinch of salt and nutmeg, then cook, stirring constantly, until it thickens.
Meanwhile, put a pot of salted water on the fire and, when it boils, drop the pasta, then drain it al dente.
Put the pasta in a bowl, mixing it with the bechamel, the diced ham, the diced cheese, a little parmesan.
If it seems too dry, add a little milk.
Pour everything into a 25×25 cm pan, then cook for about 5-10 minutes at 200 ° C, in a preheated convection oven, with the grill on, just long enough for the cheese to melt and a crunchy crust is created on the surface.
The baked tagliatelle are ready: let them rest for 5 minutes before serving.
