FAQ · Things people ask

About this recipe.

Why no cream? Every restaurant version has cream.

That's an American-Italian adaptation from the mid-20th century. In Rome, cream was never part of Alfredo di Lelio's original — the emulsion of butter, starchy pasta water, and Parmigiano creates creaminess without it. Adding cream makes it richer but obscures the butter's flavor and breaks the point of the dish.

Can I use Grana Padano instead of Parmigiano-Reggiano?

Yes. Grana Padano is milder and lower in fat, which can actually help the emulsion come together a bit more easily. It's a reasonable substitute — not heresy.

My sauce is greasy and the cheese is clumping — what went wrong?

Too much heat. Either the pasta was too hot when you added the cheese, or you returned the pan to the flame. Pull it off the heat, let it sit for 30 seconds, then add the Parmigiano with a splash of pasta water and toss off-heat.

Does it have to be fresh pasta?

No. Dried fettuccine works well, particularly bronze-die extruded, which has a rougher surface that holds the sauce better. Fresh egg fettuccine is traditional and more luxurious, but technique matters more than pasta format here.
