Fettuccine Alfredo, Butter-and-Parmesan Style
Not rated yet. Be the first.
Hot fettuccine, butter, finely grated Parmesan and a splash of the starchy pasta water, tossed off the heat until the sauce turns glossy. Black pepper, lots. The cream version is here too, for anyone who grew up on it.
The short version
Boil fettuccine in well-salted water, save a cup of the water, then toss the hot pasta with butter, finely grated Parmesan and splashes of that water until the sauce turns glossy. About 25 minutes. Grate the cheese fine and toss off the heat so it melts instead of clumping.
What makes ours better
the tricks Nonna pretends she never taught me
-
Toss with pasta water. The starch in the cooking water binds butter and cheese into a smooth sauce that clings to every strand. It also lets you skip the cream and taste the Parmesan.
-
Grate the cheese finely and add it off the heat. Fine shreds melt in seconds. Cheese tossed over a hot burner turns grainy and stringy.
-
Lots of black pepper. Pepper cuts through the richness. Crack it fresh right before serving.

Steps
nobody opens the oven door. looking at you, Dad.
-
Boil the water
Bring a large pot of water to a rolling boil. Add the salt; it should taste like mild seawater. Set a wide serving bowl or the empty pasta pot nearby.
-
Cook the fettuccine
Cook the pasta 1 minute short of the package time, until tender with a slight bite in the center. Fresh pasta takes only 2 to 3 minutes.
About 9 min. Cook mode has a timer for this step.
-
Save the water
Before draining, scoop out at least 1 cup of the cloudy cooking water. Drain the pasta but don't rinse it.
Scoop first, drain second. Once it's down the sink, the sauce is gone.
-
Toss with butter
Put the hot pasta in the warm bowl or back in the pot, off the heat. Add the butter and ½ cup of the pasta water and toss for 30 seconds until the butter melts into a loose, shiny sauce.
-
Add the Parmesan
Sprinkle in the cheese a handful at a time, tossing constantly with tongs. Add more pasta water by the tablespoon until the sauce looks glossy and coats the noodles. Stir in the pepper.
If it looks clumpy, it's too dry. A splash of hot water and a few more seconds of tossing smooths it out.
-
Serve right away
Taste and add salt if you need it. Divide among warm bowls and finish with pepper and a little more cheese. Alfredo thickens as it cools, so eat it hot.
Good to know
the stuff I’d tell you over the phone
- The cream version: melt 4 tablespoons butter in a large skillet over medium heat, add 1 cup heavy cream and bring to a gentle simmer for 2 minutes. Add the drained pasta, 1 cup finely grated Parmesan, salt and pepper, and toss over low heat until coated.
- Buy a block of Parmesan and grate it yourself. Pre-grated cheese has anti-caking starch and doesn't melt smoothly.
- Add a pinch of freshly grated nutmeg, or stir in grilled chicken or a handful of peas at the end. See baked mac and cheese with a crisp crumb top for another cheese-sauce classic.
- Storage. Best eaten right away. Fridge, 2 days. Reheat in a skillet with a splash of water or milk over low heat, stirring until smooth.
Questions, answered
the questions my cousins text me
Does real Alfredo have cream in it?
The original is just butter, Parmesan and pasta. The cream version is the one most American restaurants serve, and it's easier to keep smooth, so both are here.
Why is my Alfredo sauce grainy or clumpy?
The cheese got too hot or was too coarsely grated. Grate it fine, add it off the heat, and loosen with hot pasta water while you toss.
Can I make Alfredo sauce ahead of time?
The cream version holds in the fridge for a day. Rewarm it gently with a splash of milk and toss with fresh pasta. The butter-and-water version is best made fresh.
What pasta works best?
Fettuccine is traditional, but tagliatelle, linguine and rigatoni all hold the sauce well. Use whatever you have.
How do I thicken Alfredo sauce?
Add more Parmesan and keep tossing, or let the cream version simmer 2 to 3 more minutes. Don't use flour; it dulls the cheese flavor.
