Ingredients Method Notes

Ingredients
  

  • 12 oz fettuccine pasta
  • ½ cup (1 stick) unsalted butter
  • 2 cups heavy whipping cream
  • 2 cloves garlic, minced
  • 2 cups freshly grated Parmesan cheese (about 6 oz)
  • ¼ teaspoon freshly ground black pepper
  • ¼ teaspoon salt, plus more for pasta water
  • 1 pinch nutmeg (optional but highly recommended)
  • fresh parsley, chopped, for garnish

Method
 

Boil the Pasta
  1. Bring a large pot of water to a rolling boil and season it generously with salt — it should taste like mild seawater.
  2. Add the fettuccine and cook according to package directions until just al dente.
  3. Before draining, scoop out about one cup of starchy pasta water and set it aside.
  4. Drain the pasta but do not rinse it — rinsing washes away the starch that helps the sauce grip every strand.
Build the Butter-Garlic Base
  1. In a large, wide skillet over medium heat, melt the butter slowly until it foams gently — not browning or sizzling aggressively.
  2. Add the minced garlic and cook for about 60 seconds, stirring constantly, until warm and fragrant. Do not let it brown or it will turn bitter.
Add the Cream and Simmer
  1. Pour the heavy cream into the pan slowly, stirring as you go.
  2. Increase the heat slightly to bring it to a gentle simmer, with small bubbles forming around the edges.
  3. Let it simmer for 5 to 7 minutes, stirring occasionally, until the cream reduces by about a quarter and coats the back of a spoon.
  4. Add the black pepper and a tiny pinch of nutmeg, then stir to combine.
Melt in the Parmesan
  1. Reduce the heat to low.
  2. Add the Parmesan in two or three batches, stirring constantly between each addition until fully melted before adding more.
  3. If the sauce feels too dense, splash in reserved pasta water one tablespoon at a time until it reaches the desired consistency.
Toss the Pasta and Serve
  1. Add the drained fettuccine directly into the sauce and use tongs to toss everything together over low heat for one to two minutes, allowing the pasta to absorb the sauce.
  2. Taste and adjust salt as needed.
  3. Plate and garnish with fresh parsley and extra Parmesan. Serve immediately while steaming hot.

Notes

Do not rinse the pasta after draining — rinsing removes the starch that helps the sauce cling to the noodles. Reserve about 1 cup of pasta water before draining to loosen the sauce as needed. Always grate Parmesan fresh from the block; pre-grated canister cheese contains anti-caking agents that prevent smooth melting. Keep heat low when adding cheese to avoid a lumpy or grainy sauce. A pinch of nutmeg is optional but highly recommended for authentic flavor depth. Store leftovers in an airtight container in the refrigerator for up to 3 days. Do not freeze — cream-based sauces tend to separate when thawed. Reheat gently on the stovetop over low heat with a splash of cream or milk, stirring slowly. Avoid the microwave as it can make the sauce oily. The sauce can be made up to 24 hours ahead and refrigerated separately; reheat slowly with a splash of cream before tossing with freshly cooked pasta.
