Classic Alfredo Pasta Sauce

Alfredo is at once comfort food and a canvas: this version leans into purity—just butter, cream, whole milk and Parmigiano-Reggiano—to produce a sauce that’s glossy, clingy and unmistakably savory. The butter gives silk, the cream supplies body, and the splash of whole milk keeps the mouthfeel light enough so the cheese can shine; a pinch of freshly grated nutmeg adds a warm, floral lift while parsley brightens the plate. Freshly grated Parm is essential here because it melts into the sauce rather than graining and contributes a nutty, salty backbone.

What makes this recipe reliably excellent is technique rather than complexity: low, steady heat, gradual incorporation of cheese, and a little starchy pasta water to marry the fat and protein into a smooth emulsion that clings to fettuccine. It’s quick enough for a special weeknight but elegant enough for company; you can nudge it richer with extra butter or lighter with a touch more milk, and it will still feel cohesive because the method protects the sauce from splitting.
