Heat oil in a large skillet over medium-high heat. Add onion, reduce heat to medium-low, and cook, stirring occasionally, until softened, about 7 minutes.

Heat oven to 400°.

Bring a large pot of salted water to boil. Add ziti and cook for 7 minutes (the pasta will not be tender); drain and transfer to a large bowl. Add sauce and stir to combine. In a small bowl, lightly beat together eggs and milk; add to pasta and stir to combine. Stir in Pecorino and prosciutto.

Lightly oil a 3- to 4-quart baking dish; transfer pasta to dish and sprinkle with Parmigiano-Reggiano. Bake until top is lightly golden and pasta is al dente, about 15 minutes. Serve immediately.
