Heat up a pan and saute mushrooms, onion and garlic in 2 tablespoons olive oil until the mushroom starts to golden and the onion is soft.
Add 1/2 cup chicken stock, 1 1/2 cup cream and 2 tablespoons chopped fresh dill.
Let it simmer for 5 minutes and season with salt and pepper.
Cook up enough pasta for 4 people, remember to add salt to the water.
Boil until al dente.
Strain and place in a bowl.
Add the sauce, mix and serve with shaved Parmesan on top.
Notes
To make this vegetarian, use vegetable stock instead. Conversely, I sometimes add sauteed chicken, beef, or veal to the dish to make it a bit more hearty.
