Creamy Mushroom Pasta with Caramelized Onions and Spinach

This pasta was so yummy! I loved the addition of the caramelized onions and the creamy sauce just made it great.  This recipe is adapted from Julia's Album.

2 tbsp olive oil
3 onions (sliced)
10 or 15 small mushrooms (sliced)
3 cups spinach
8 oz fettuccine pasta
2/3 cup heavy cream
1/3 cup milk
1 cup grated Parmesan cheese
salt

Heat 1tablespoon of olive oil over high heat and saute onions for 10 minutes while stirring constantly. Turn down the heat and cook for 10 more minutes, onions should be browning without burning. Add a dash of salt and cook for 10 more minutes over low heat. In a separate pan, while caramelizing the onions, add 1 tablespoon of olive oil, add the mushrooms and a pinch of saute and saute over low heat for 15 minutes. Begin to boil the pasta. Add the mushrooms to the pan with the onions and stir in the spinach until it is wilted. Stir in the heavy cream, milk and parmesan cheese to the onion mixture, melt over low heat. Drain the pasta, toss in the sauce and serve.
