This authentic Italian Fettuccine Alfredo uses just butter, Parmigiano-Reggiano, and pasta water to create a luxuriously creamy sauce without any cream. The traditional Roman technique of vigorous tossing creates an emulsion that coats every strand of pasta in silky perfection. Simple ingredients, spectacular results.
Large serving bowl or wide skillet Should be warmed before use
Fine grater or microplane For grating cheese
Measuring cups
Ladle For pasta water
Pasta fork or tongs For tossing
Instant-read thermometer Optional, for checking pasta water temperature
Ingredients
1poundfettuccine pasta450g, fresh or dried, bronze-cut preferred
8tablespoonsunsalted butter113g or 1 stick, cubed
2cupsParmigiano-Reggiano cheese170g or 6 ounces, finely grated
1cuppasta water240ml, reserved from cooking
1tablespoonkosher saltFor pasta water
freshly ground black pepperTo taste
Instructions
Cube the butter into 1-inch pieces and let soften at room temperature for 10 minutes. Finely grate the Parmigiano-Reggiano using a microplane until it resembles snow.
Fill a large pot with 4 quarts of water and add 1 tablespoon kosher salt per quart. Bring to a rolling boil over high heat.
Add fettuccine to boiling water and cook until al dente (8-10 minutes for dried, 2-3 for fresh). Reserve 2 cups pasta water before draining, letting it cool to about 150°F.
In a large warmed serving bowl, place half the butter and half the grated cheese. Do not stir yet.
Transfer hot pasta directly to the bowl using tongs. Add 1/3 cup warm pasta water and begin tossing vigorously using a lifting and folding motion.
While tossing continuously, gradually add remaining cheese and butter. Add more pasta water 1 tablespoon at a time if sauce seems thick. Continue tossing for 2-3 minutes until sauce is creamy and glossy.
Season with freshly ground black pepper and divide immediately among warmed serving bowls. Serve at once while sauce is at its silkiest.
Notes
Temperature is critical: pasta water should cool to 150°F before adding to prevent cheese from seizing. Use an instant-read thermometer for accuracy.
Grate cheese finely using a microplane for smoothest melting. Pre-grated cheese contains anti-caking agents that create a grainy texture.
Use authentic Parmigiano-Reggiano aged at least 12 months for best flavor and melting properties. Domestic parmesan won't produce the same results.
Vigorous tossing is essential to create the emulsion between butter, cheese, and pasta water. This motion creates creaminess without cream.
Warm serving bowls in a 200°F oven or with hot water before serving. Cold plates cause the sauce to solidify immediately.
Work quickly once pasta is cooked. The heat from the pasta melts the butter and cheese, so timing is crucial.
Store leftovers in an airtight container for up to 3 days. Reheat gently with 2-3 tablespoons water, stirring constantly over low heat.
Don't freeze this dish as the sauce separates and becomes grainy upon thawing.
For variation, add grilled chicken, sautéed shrimp, or blanched vegetables like broccoli or asparagus.
Bronze-cut pasta has a rougher texture that helps sauce cling better than regular pasta.
