Who doesn't love a bowl of creamy pasta and who doesn't love mushrooms and garlic. You know where I am going; This Pasta with Creamy Mushroom Sauce will be dead center in your wheelhouse.
Bring water and salt to a boil, add the pasta and cook according to the directions on the packaging.
While the pasta cooks, heat oil and butter in a skillet, add the garlic and onions until translucent. Then add the mushrooms and some salt and pepper. (2-3 minutes) (Note 1)
Cook until the mushrooms are brown and tender and most of moisture is evaporated. (2-3 minutes)
Add the cream and white wine to the skillet and 1/4 cup of pasta water. Simmer until thickened, stir occasionally. (2-3 minutes) (Note 2)
Add the Parmesan cheese half of the rosemary and salt and pepper if desired. You may want to add more pasta water to achieve the thickness you prefer.
Add pasta and toss to coat the pasta with the sauce.
Divide over 2 bowls and sprinkle with the remaining rosemary. (Note 3)
Notes
For this sauce I prefer to slice the mushroom over chopping them in quarters. The slices are more tender and can 'slide' easy with the sauce to coat the pasta.
If you don't like to use wine, add chicken of vegetable broth instead.
If you don't like rosemary, you can use chives, parsley or thyme.
