Preheat the oven to 180°C.

First prepare the bechamel sauce. In a pan melt the butter and add the flour, stirring continuously. Once mixed well, take off the heat and add the milk. Mix again and return to the heat. Continue to mix until the sauce thickens. Add salt, pepper and a small handful of the grated cheeses and mix until smooth.

In a pot with plenty of boiling salted water cook the tagliolini until al dente. While the pasta is cooking, in a large ovenproof pan, melt the butter and add the ham. Once the tagliolini is al dente, drain and transfer to the pan with the ham. Add ¼ cup of pasta water and mix. Add half the bechamel and mix. Then top the pasta with the remaining bechamel and grated cheeses. Bake in the oven for 15 minutes until golden and bubbling!
