For the Italian pasta quiche, first preheat the steamer to 100 °C.
Cook the pasta al dente in salted water according to the package instructions and rinse immediately with cold water.
Heat the oil in a pan. Finely chop the onion and sauté. Add the parsley.
In a large bowl, place the well-drained pasta and mix well with the eggs, milk, ham, onion-parsley mixture and cheese, then add salt and pepper.
Butter a baking dish, pour in the mixture and steam in the DG at 100 °C for 40 minutes.
If you want the surface crispy, you can gratinate the quiche under the grill for another 4 minutes.
Before serving, sprinkle the Italian pasta quiche with grated Parmesan.
