Melt the butter in a large pot over low heat. Add the olive oil and onions and cook for 15-20 minutes or until the onions have reduced significantly and caramelized. Don’t rush this process or the onions will burn.

Stir in the mushrooms and cook for another 10 minutes or until the mushrooms have reduced significantly.

Stir in the heavy cream and parmesan cheese until it is fully melted. Bring the mixture to a simmer again, and stir in the cooked pasta.
