Ingredients

Why this recipe works

The combination of butter and heavy cream creates a rich, velvety base that carries the flavor of the parmesan beautifully. Simmering the sauce gently allows the ingredients to meld without breaking, resulting in a smooth, glossy texture.

The starch from the pasta water acts as an emulsifier, helping the sauce cling to the noodles and preventing it from turning greasy or watery.

Tossing the hot pasta directly into the sauce ensures that every strand is evenly coated. The residual heat from the pasta helps the sauce thicken slightly, creating a luxurious mouthfeel. Using freshly grated parmesan rather than pre-shredded cheese is crucial, as it melts smoothly and avoids the clumping that can occur with anti-caking additives.

Notes and substitutions

For the best flavor, use a good-quality parmesan cheese and grate it yourself. Pre-shredded cheese often contains cellulose, which can prevent smooth melting.

Unsalted butter allows you to control the salt level, especially since the pasta water is heavily salted. Heavy cream provides the richness; substituting with half-and-half will yield a lighter sauce but not as indulgent.

Garlic powder is used here for its mellow, even flavor; fresh garlic can be sautéed in the butter for a more pungent kick. Italian seasoning adds a subtle herbaceous note, but you can adjust the amount to taste. If you prefer a thinner sauce, add more pasta water gradually until the desired consistency is reached.

• fettuccine: Use tagliatelle or linguine if fettuccine is unavailable; they hold the sauce just as well.
• heavy cream: Half-and-half can be used for a lighter sauce, though it will be slightly less rich.
• garlic powder: Substitute 2 minced garlic cloves for a more pungent garlic flavor.
• Italian seasoning: A mix of dried oregano, basil, and thyme works in place of Italian seasoning.
