Creating this wonderful Parmesan Mushroom Rice is as easy as following these simple steps:

1. Heat Oil and Butter: In a medium saucepan, heat the olive oil and butter over medium heat until melted.
2. Sauté Onions and Garlic: Add the chopped onion and minced garlic. Sauté until the onion is translucent, about 3-4 minutes.
3. Cook Mushrooms: Stir in the sliced mushrooms and cook for an additional 5-6 minutes until they have softened.
4. Add Rice: Add the Arborio rice to the saucepan and stir well, coating each grain in the oil and butter mixture.
5. Pour in Broth: Gradually add the broth, one cup at a time, stirring continuously. Allow the rice to absorb most of the liquid before adding the next cup. This should take about 15-20 minutes.
6. Check for Doneness: Once the rice is creamy and al dente, remove it from the heat.
7. Stir in Cheese and Cream: Fold in the grated Parmesan cheese and heavy cream, if using. Season with salt and pepper to taste.
8. Serve: Spoon the creamy rice into bowls and garnish with fresh parsley for a pop of color.
