I used gluten-free fettuccine, but any type of pasta would work as well. Long pasta, such as spaghetti or tagliatelle are two other great choices.
If you are not vegan and you can find Graviera, give it a go. It is a very tasty Greek cheese.
If you are following a vegan diet you can still enjoy this pasta dish. Simply, substitute Parmesan cheese with 5 tablespoon nutritional yeast or with vegan Parmesan.
If you are following a gluten-free diet, always make sure that your pasta is certified gluten-free.
Store the Alfredo pasta dish in an airtight container, in the fridge, for up to 4 days.
