Bring a large pot of salted water to a boil and cook the fettuccine until al dente, usually 10-12 minutes. Reserve 120 ml of the cooking water, then drain.
While the pasta cooks, melt the butter in a large frying pan over medium-low heat and cook the minced garlic for 1 minute without letting it brown.
Pour in the cream, bring it to a gentle simmer and cook for 3-4 minutes, until slightly thickened.
Lower the heat and stir in about three-quarters of the parmesan, a handful at a time, until the sauce is smooth.
Add the drained fettuccine to the pan and toss for 1-2 minutes, adding a little of the reserved cooking water if the sauce is too thick.
Season with black pepper and a little salt if needed.
Serve at once, topped with the remaining parmesan and the chopped parsley.
