Cook the pasta according to the package instructions, until al dente. Drain and set aside.
Combine the butter and oil in a large skillet over medium-high heat. When the butter has melted, add the mushrooms and cook for 5 to 7 minutes, until golden around the edges.
Add the garlic, Italian seasoning, 1/2 teaspoon salt, and 1/4 teaspoon black pepper and cook for 1 minute, until fragrant.
Reduce the heat to low, add the pasta and cream and stir to coat.
Fold in the parmesan cheese. If desired, for a thinner sauce, add more cream.
Season to taste with salt and pepper. Garnish with parsley and serve.
