three ingredient fettuccine alfredo

I tried this recipe of my Aunt's this week, it was really good and not quite as rich as regular Alfredo. Plus it is easy.

1 cup of room temperature unsalted butter

8 oz. of freshly grated Parmesan cheese

1 pound pasta

salt

Beat the butter and cheese together in a bowl until creamy. Cook pasta in a large pot of salted water, cook pasta until al dente. Reserve 1/2 cup of cooking water. Drain the pasta and return pasta to the pot. Toss pasta with 1/2 teaspoon of salt, the cheese mixture and pasta water. Top with more cheese if desired.
