Bring a large pot of water to the boil and cook the pappardelle according to the package directions.
While the pasta is cooking, put a large skillet over medium-high heat. Cook the pancetta until it starts to brown, about 5 minutes. Add the mushrooms and cook for 2 to 3 minutes, then add the cream. When the cream is hot, add the Parmesan and stir.
Drain the pasta and add it to the skillet. Stir well and season with some pepper. I find it does not usually need salt because of the salty pancetta and Parmesan.
Serve immediately. I like to serve it with an arugula salad.
