How to Make Authentic Alfredo Sauce (Recipe)?

This article will discuss Alfredo sauce, how to make Authentic Alfredo Fettuccine, and how to make the traditional Alfredo sauce for ready-made pasta noodles at home. Consume it to the end to learn the most authentic Italian Alfredo Sauce Recipe.

What is Authentic Alfredo Sauce for Alfredo Fettuccine?

There is no such thing as Alfredo “sauce. A sauce, by definition, is made separately and then added to the dish.

However, Alfredo sauce is not made separately but is part of the Fettuccine Alfredo recipe. It is made by stirring butter and Parmigiano Reggiano into slightly sloppily drained and still boiling fettuccine noodles. 

In Italy, it is known by different names, such as “pasta Bianco” and “pasta al burro.” In northern Italy, it’s pasta in Bianco; in central and southern Italy, pasta al burro is made with extra virgin olive oil and cheese.

The American version you might have eaten is loaded with lots of high-fat cream and extra ingredients. But the Italian version is more straightforward

The authenticity came from only three main ingredients:

Parmigiano – Reggiano cheese

Unsalted butter

Egg fettuccine noodles.

In some places, people add garlic, Parmesan, and parsley to the recipe.

What is Authentic Alfredo Sauce’s Origin?

Alfredo is not an actual sauce but a thick paste made with smothering lots of butter with Parmigiano Reggiano inside a dish filled with steaming egg fettuccine.

The source of the Alfredo sauce goes back to 1908 when Alfredo di Lelio, an Italian restaurateur, created Fettuccine Alfredo. He made the sauce of cheese and butter for a dish of noodles that later became one of the staple foods of Italian cuisine that is more famous in America than in Italy. 

The original and most authentic recipe is served in the restaurant “Alfredo alla Scrofa” in Rome, a place American tourists have discovered and made famous.

How to Make Authentic Alfredo Sauce and Fettuccine Pasta?

If you want to go authentic, you also need authentic ingredients. 


  • Unsalted Butter 
  • Parmigiano Reggiano Cheese / Parmesan
  • Egg Fettuccine Noodles

Parmigiano Reggiano Cheese / Parmesan

Parmigiano Reggiano Cheese is the most popular cheese among connoisseurs. It is made with unpasteurized skimmed or partially skimmed milk. 

Getting your hands on authentic Parmigiano Reggiano outside Italy is not easy. Still, you can buy the imitated version of the original Parmigiano Reggiano cheese called Parmesan. Or your best bet is to make it at home using the following Recipe. 

If you buy it from the market, get the new block of Parmigiano Reggiano grater, which should be no less than 27 months old.

Egg Fettuccine Noodles

You can’t make Fettuccine Alfredo with spaghetti, linguine, durum wheat pasta, or other noodles. It would help if you only looked for fettuccine noodles made from thin egg-dough tagliatelle. 

Or you can use dried or fresh pasta made from egg dough and not durum wheat-dried pasta. The flavor and texture of egg pasta are essential for this dish.

Here’s how to make homemade egg fettuccine pasta, step by step:

Step 1: Mix the ingredients. 

Take a mound of durum wheat flour. Make a well in the center and add all the wet ingredients, such as eggs, olive oil, or water. Use a whisk, fork, or fingers to mix the ingredients until they form a shaggy dough.

Step 2: Knead the dough. 

Knead the dough by pressing and punching it with your hand. Work on the surface until the coarse dough forms a shiny, smooth ball. After kneading, allow the dough to rest to relax the gluten and hydrate the flour.

Step 3: Shape the dough and make pasta. 

Pasta comes in many shapes, but we need fettuccine here. 

Produce sheets of pasta dough using the roller you have. It would be best if you also had a chitarra or pasta cutter to cut through rolled pasta dough to make fettuccine or linguine. 

Once you have cut the pasta, you can choose to dry or freeze it. Italians prepare their fettuccine fresh, cooking it the same day. However, you can also dry or freeze homemade pasta to extend its shelf life.


Last but not least, you need unsalted butter. The butter should be sweeter compared to the sloppiness of Parmigiano Reggiano. 

The right tool

For grating cheese, it’s essential to use the right side of the box grater. The big holed side is suitable for shedding tenderer cheese, but for Parmigiano Reggiano, you need the more delicate, finer side (with the tiny holes surrounded by four Spikes).

Making of Fettuccine Alfredo

Now without further ado, let’s get to the Recipe. Here is a step-by-step process of making authentic alfredo sauce or fettuccine alfredo at home. 


Bring 2–4 quarts of lightly salted water to a quick boil and roll out the fettuccine noodles. It will usually take 4–6 minutes to cook, depending on the thickness of the noodles. 

Do not overcook it; it needs to be firmer or al dente with starchy enough liquid.


Meanwhile, your noodles are about to get cooked; take a few knobs of unsalted butter and place them in the bottom of the bowl.

Once your noodles get cooked, drain out the noodles and some of their starchy water.

Note: don’t fully drain them; otherwise, you will not be able to make a sauce.


Use a pair of tongs to add the fettuccine on top of the unsalted butter. Finally, top with a handful of freshly grated Parmigiano Reggiano.


Toss everything together until combined.

At first, it might seem like a watery mess, but it will become a nice creamy sauce.

Optional: Add salt and pepper to taste.

That’s it! The creamy fettuccine Alfredo is ready to serve. 

Real Fettuccine Alfredo from Italian Chefs

You don’t need to add high-fat cream or any other ingredients. To make an authentic Italian recipe, you need egg fettuccine, unsalted butter, and freshly grated Parmigiano Reggiano.  

If you want to make only alfredo sauce, use some starchy water from Fettuccine pasta, add it to the unsalted butter, top with cheese, and mix using the technique mentioned before. 

The restaurant Alfredo alla Scrofa is known for making the best version of this dish, with handmade fettuccine, super thinly grated cheese, and outstanding chefs’ help. But what’s most important is the fresh ingredients and how the pasta gets worked with the butter and cheese to cream it up, making it exceptionally creamy. 

You can see that there is no cream added; the creaminess is created simply by amalgamating the pasta cooking water partially retained when plating, the abundant butter, and the cheese.
