Meanwhile, bring a large pot of salted water to a boil. Add the fettuccine and cook, stirring occasionally, until tender but still firm to the bite, about 4 minutes. Drain. Add the pasta, the remaining ½ cup of cream, the Parmesan, and ¼ teaspoon each of salt and pepper to the cream sauce in the skillet. Toss over low heat until the sauce thickens slightly, about 1 minute. Season with more salt and pepper to taste. Transfer the pasta to wide, shallow serving bowls and serve immediately.
