In a medium skillet over medium-high heat, melt butter with olive oil. Add the mushrooms and garlic and cook until the mushrooms are soft and tender, about 3–5 minutes.
Add the heavy cream, grated parmesan, cream cheese, Italian seasoning, salt, and pepper. Stir well until the cheese is melted and the sauce is smooth and bubbling.
Remove from heat and serve immediately. Top with fresh chopped parsley for a burst of color and flavor.
