Pour the dried mushrooms into a bowl and add 2 cups of hot water. Let soak for 30 minutes, then fish the mushrooms out and rinse them under cold water. Put the mushrooms on a paper towel lined plate to dry. Pour the soaking liquid through a a sieve lined with a coffee filter to remove any impurities, and set it aside.

Put a large pot of salted water on high heat but don't add the noodles yet.

Add a splash of olive oil to a large pan on medium-high heat. Season the chicken pieces with salt and pepper and fry them until they're browned and cooked, about 6 or 7 minutes. Remove the chicken to a plate.

Drop the noodles into the pot of boiling water and cook about 1 minute shy of the instructions. Continue making the sauce as you wait.

Roughly chop the mushrooms and add them to the pan you used for the chicken. Add a splash of olive oil if the pan seems a little dry. Fry the mushrooms until they brown a little (about 3 or 4 minutes).

Add the onion and garlic and continue frying for 2 minutes. Return the chicken to the pan. Add the mushroom liquid and let simmer until only a few tbsp of liquid remains.

Turn the heat down to medium. Add the cream, butter, a pinch of salt and several grinds of freshly cracked black pepper. Whisk in the parmesan. Toss in the mostly-cooked pappardelle noodles and give them a few minutes to soak up some of the sauce. Serve topped with more grated parmesan and a sprinkle of Italian parsley.
