Pour in heavy cream and bring to a simmer. Stir in Parmesan cheese, salt, pepper, and Italian seasoning, mixing until smooth and creamy.
Boil the tortellini according to the package instructions, then drain and add it to the skillet with the Alfredo sauce.
Stir in crumbled bacon, mix everything together, and garnish with fresh parsley. Serve hot and enjoy!
