Classic Fettuccine Alfredo Recipe
Quick Answer
Authentic Fettuccine Alfredo uses only 3 ingredients: fettuccine pasta, butter, and Parmigiano-Reggiano. Cook pasta al dente, toss with cold cubed butter and finely grated Parmesan off the heat, adding pasta water gradually to create a silky emulsion. No cream in the original Roman recipe.
Rich, creamy Alfredo sauce with buttery Parmesan clinging to every strand of pasta
By Sarah Mitchell • June 14, 2026
Fettuccine Alfredo is the ultimate indulgent pasta — silky ribbons of fettuccine coated in a luscious sauce of butter, heavy cream, and freshly grated Parmesan that clings to every strand. It's decadent, it's simple, and it takes just 20 minutes from start to finish.
The key to a perfect Alfredo is using freshly grated Parmigiano-Reggiano (never pre-shredded — it won't melt smoothly) and reserving some pasta cooking water. The starchy water emulsifies the sauce, preventing it from separating and keeping it silky smooth.
Serve it as-is for a vegetarian main, or top with grilled chicken, shrimp, or crispy pancetta. A generous crack of black pepper and a shower of extra Parmesan at the table are non-negotiable.

Frequently Asked Questions
Does real fettuccine alfredo have cream?
No — authentic Fettuccine Alfredo from Rome uses only butter, Parmigiano-Reggiano, and pasta water. The creamy texture comes from emulsifying the cheese and butter with starchy pasta water. The cream-based version is an American adaptation.
What cheese is best for fettuccine alfredo?
Parmigiano-Reggiano (aged 24+ months) is essential. Pre-grated cheese won't work as well because it contains anti-caking agents that prevent smooth melting. Grate it yourself on a Microplane for the silkiest sauce.
Why is my alfredo sauce grainy?
The heat is too high. Always toss the cheese and butter with pasta OFF the heat. Add pasta water gradually (1-2 tablespoons at a time) and toss constantly. The residual heat from the pasta is enough to melt everything into a smooth emulsion.
