Baked bucatini sformato recipe- sformato di bucatini al forno

1. Clean and slice the mushrooms and heat them over a gentle flame, until the water they contain has evaporated.

2. Sauté the prosciutto in a hint of butter with the onion, and then mince it with the mushrooms, and, if you're adding it, the truffle. Melt the remaining butter, add the mushroom mixture to it, and simmer it all for about 10 minutes.

3. Boil the bucatini in salted water and drain them when they're still quite al dente. Transfer them to a bowl and add to them the mushrooms, cream, most of the Parmigiano, tomato sauce, herbs, and if need be , a little broth. Beat the yolks and add them, then beat the whites until firm and fold them in too.

4. Preheat your oven to 350 F (175 C).

5. Grease a mold large enough to hold everything, pour the bucatini mixture into it, level it, dot the top of the mold with the remaining butter, and sprinkle the remaining cheese and the bread crumbs over it too. Bake for about an hour, or until browned. Unmold it and serve it hot.
