A simple Alfredo sauce made the proper way — with butter, Parmigiano Reggiano, pasta water and a little technique.
Serves: 4
Time: 10 minutes
Difficulty: Beginner
Best for: Fresh fettuccine, quick dinners, comfort food
Alfredo sauce is often made heavy with cream, but the original idea is much simpler and more beautiful.
Good Alfredo is about emulsion: hot pasta, butter, Parmigiano Reggiano and starchy pasta water coming together into a glossy sauce that coats the pasta without feeling too heavy.
It is simple, but simple food needs attention. The heat matters. The cheese matters. The pasta water matters.
INGREDIENTS
400g fresh fettuccine
90g unsalted butter, cut into cubes
120g Parmigiano Reggiano, finely grated
120–180ml hot pasta water
Sea salt, to taste
Black pepper, optional
METHOD
1. Bring a large pot of water to the boil and season it well with salt.
2. Cook the fresh fettuccine until just tender. Fresh pasta cooks quickly, usually in 2–3 minutes.
3. While the pasta cooks, place the butter in a large warm pan or bowl.
4. Transfer the pasta directly onto the butter, keeping the pasta water.
5. Add a splash of hot pasta water and toss gently until the butter starts to melt and coat the pasta.
6. Add the Parmigiano Reggiano gradually, tossing constantly.
7. Add more pasta water as needed until the sauce becomes glossy, creamy and smooth.
8. Taste and adjust with a little salt if needed.
9. Finish with black pepper if you like, and serve immediately.
ANDREA’S NOTES
The sauce should never feel dry or oily. If it looks too thick, add more hot pasta water. If it looks greasy or split, the heat was probably too high or the cheese was added too quickly.
Use finely grated Parmigiano Reggiano so it melts easily into the sauce.
Do not cook the sauce aggressively in the pan. Alfredo is built with gentle heat, movement and pasta water.
The pasta water is not just water — it is what helps the butter and cheese become a sauce.
BEST PASTA TO SERVE IT WITH
Alfredo belongs with fresh fettuccine. The wide ribbons catch the butter, Parmigiano Reggiano and pasta water beautifully, so every bite feels rich but not heavy.
