2 cups portabella mushrooms or 2 cups cremini mushrooms

Melt half the butter in medium saucepan over medium/low heat.
Add the garlic, onion, and mushroom and saute until the liquid is released. 5-7 minutes.
Add the remaining butter, cream, and white pepper and bring mixture to a simmer.
Stir often.
Begin your noodles or tortellini at this point so everything will be done at the same time.

When sauce has thickened add the Parmesan cheese and stir frequently until smooth. Remove from heat when sauce has reached desired consistency.
