Chop the prosciutto ham into small chunks. Tip: Rolling the sliced ham before cutting creates perfect little morsels.

In a mixing bowl, combine the hard-boiled egg yolks, grated Parmesan cheese, black pepper, and oregano. Use a fork to break up the eggs until roughly combined.

Add the chopped prosciutto to the bowl with the egg mixture.

Pour in the half-and-half and stir everything together until well combined.

Transfer the mixture to a saucepan and simmer over low heat. Be patient and stir occasionally to prevent the sauce from breaking.

Meanwhile, cook your pasta of choice according to package instructions until al dente.

If the sauce isn't thick enough after simmering, mix a teaspoon of cornstarch with cold water and add it to the sauce, stirring until it reaches your desired consistency.

Drain the pasta and return it to the pot.

Pour the creamy prosciutto sauce over the pasta and toss gently to coat evenly.

Serve immediately, garnished with additional black pepper or Parmesan if desired.
