Real Alfredo is not a jar of cream and cheese powder. The original Roman version — butter, pasta water, and aged Parmigiano — is one of the simplest, most satisfying sauces in existence. This version adds pan-seared chicken and a small amount of cream to make it more filling, while keeping the focus on high-quality parmesan and properly emulsified sauce technique.
Ingredients
Cook the Pasta and Chicken
Cook fettuccine in heavily salted water until al dente. Reserve 200ml of the starchy cooking water before draining — this is what makes the sauce emulsify. Meanwhile, season and sear chicken in butter 4 minutes per side until golden. Slice and set aside.
Build the Sauce
In the same pan over low heat, melt butter. Add garlic, cook 60 seconds. Add cream and 100ml pasta water, stir and bring to a gentle simmer. Remove from heat before adding parmesan — adding cheese over active heat causes it to clump.
- Add pasta directly into the sauce off the heat
- Toss vigorously, adding pasta water a splash at a time until silky and coating
- Add sliced chicken, toss again
- Season with salt, pepper, and a pinch of nutmeg
- Serve immediately — Alfredo waits for no one
"Pasta water is not an afterthought. The starch it carries is what turns butter and cheese into a sauce that clings. Without it, you get grease and cheese — not Alfredo."
Use Parmigiano-Reggiano and grate it yourself on the finest side of your grater. Pre-grated parmesan contains anti-caking agents that prevent proper melting and give the sauce a grainy texture.
