Bring a pot of salted water to a boil and cook the pasta according to the package directions. Once done, drain and set aside.
In a frying pan, heat some oil over medium heat. Add half of the Parma ham and fry until it becomes crisp, then remove it from the pan and set aside.
Next, add the mushrooms to the pan and cook for about two minutes. Stir in the crème fraîche and bring the mixture to a boil.
Add the cooked pasta, Parmesan, the remaining Parma ham, and parsley, then toss everything together over the heat. Season to taste.
Serve the pasta with the crispy Parma ham on top, and consider pairing it with a fresh green salad and some crusty bread on the side.
