Before you start
What this method is trying to achieve
Alfredo tightens quickly. Keep the cream mixture warm rather than violently boiling, add pasta and cheese while tossing, then use reserved starchy water to control the final consistency.
Success looks like
Know the target before you cook
The sauce should be smooth, glossy and fluid enough to coat the fettuccine without greasy separation or a dry cheese paste.
Ingredients
What you need
Pasta
- 450 g fettuccine — About 1 lb.
Sauce
- 360 ml heavy cream — About 1 1/2 cups.
- 85 g unsalted butter, cubed — About 6 tablespoons.
- 90 g Parmesan, finely grated — About 1 cup.
Seasoning
- 1/4 tsp freshly grated nutmeg — Optional but classic in many American versions.
- kosher salt and black pepper — To taste.
Method
Cook by the cues, not just the clock
Cook pasta
Boil the fettuccine in salted water until al dente. Reserve at least 240 ml / 1 cup pasta water before draining.
Warm cream and butter
While the pasta cooks, combine cream and butter in a wide skillet and bring only to a gentle simmer. Add nutmeg, salt and pepper, then reduce heat to low.
Add pasta
Transfer the hot drained fettuccine to the skillet and toss until the ribbons are coated in the warm cream mixture.
Add cheese
Sprinkle in Parmesan while tossing over low to medium-low heat until the sauce becomes smooth and cohesive.
Adjust and serve
If the sauce tightens, add reserved pasta water a tablespoon at a time until glossy and fluid. Serve immediately.
Critical checkpoints
Stop here and check
Cream only gently simmering?
The cream is hot and steaming with small bubbles, not violently boiling.Lower the heat if it is boiling aggressively.
Cheese incorporated gradually?
Parmesan melts into a smooth coating while the pasta is tossed.Use low heat and pasta water if the sauce tightens.
Alfredo sliding off or pooling?
The noodles look bare while sauce stays in the pan or bowl.Use CookClue's pasta-sauce-wont-cling diagnosis to check starch, finishing and sauce consistency.

Storage, reheating & substitutions
Storage
Best served immediately. Refrigerated sauce thickens considerably.
Reheating
Warm slowly with a splash of water or milk while stirring; avoid high heat.
Substitutions
Tagliatelle or another broad ribbon pasta can replace fettuccine.
