Ingredients

Why this recipe works

The method begins with a quick roux—butter and flour cooked together—which gives the sauce body and prevents it from separating. This ensures a smooth, stable emulsion that coats the pasta evenly.

The addition of starchy pasta water not only thins the sauce to the right consistency but also adds a silky texture that clings to the noodles, creating that signature Alfredo gloss.

Using freshly grated parmesan is crucial for a smooth melt. Pre-shredded cheese often contains anti-caking agents that can make the sauce grainy.

By removing the pan from the heat before adding the cheese, the parmesan melts gently into the warm cream, resulting in a velvety, cohesive sauce. The garlic powder and Italian seasoning add depth without overpowering the delicate dairy flavor.

Notes and substitutions

For the best flavor, use freshly grated parmesan from a wedge—it melts more smoothly and tastes brighter than pre-shredded. Heavy whipping cream gives the sauce its richness; half-and-half can be used for a lighter version, but the sauce will be thinner. The reserved pasta water is essential for adjusting consistency, so don't skip it.

This recipe uses garlic powder for convenience and even distribution. If you prefer fresh garlic, sauté 2 minced cloves in the butter for 1 minute before adding the flour. A wide skillet gives the sauce room to coat the pasta evenly. For a more decadent dish, add a pinch of nutmeg—though the video doesn't, it's a classic complement.
