Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente.

Drain the pasta and set aside, reserving 1 cup of pasta water.

In a skillet, heat olive oil over medium heat. Add minced garlic and sauté until fragrant, about 1 minute.

Add the Boursin cheese, heavy cream, and broth to the skillet. Stir until the cheese is melted and the sauce is smooth.

Add the cooked pasta to the skillet, tossing to coat in the sauce. If the sauce is too thick, add reserved pasta water as needed.

Stir in Parmesan cheese, salt, pepper, and Italian seasoning (if using).

Serve the pasta hot, garnished with chopped parsley.
