What You Will Need To Follow This Tutorial

Alfredo Sauce

The first thing that you will need to be able to thicken alfredo sauce is a thin alfredo sauce! It’s possible to make your own alfredo sauce at home, or you can buy a jar at the store.

Alfredo sauce is a cream-based sauce that is typically made of butter, heavy cream, and Parmesan cheese. That’s all it takes to make this tasty sauce! The key to making a thick sauce from scratch is lots and lots of practice, but there are ways to thicken sauces that are too thin.

Option #1: Skillet


A skillet is a pan with slanted sides that has a big surface area. This makes it ideal for cooking things that need to be browned evenly or for reducing things like sauces.

When it comes to alfredo sauce, cooking it in a skillet for a long period of time over low heat can help the sauce reduce and become thicker.

Option #2: An Egg

Beat the egg yolks.

Eggs are often used as binding agents to help things stick together. Their texture and properties make it possible for them to do this, and using eggs when combining your sauce with your pasta is no exception.

Option #3: More Parmesan

While some cream sauces have a roux as a base, there is no flour or starches used in traditional alfredo sauce. The thickening agent in alfredo sauce is Parmesan!

Parmesan is a hard, dry cheese made with skim milk that has a complex and salty flavor. This cheese is what gives alfredo its distinctive flavor.

Step-by-Step Instructions

Option #1: Use A Skillet!

Step #1: Simmer That Cream

The most important step to making sure that your alfredo sauce gets thicker is simmering it for a long period of time over low heat. This will allow the water in it to slowly evaporate, creating a thicker sauce.

If you are making your pasta sauce from scratch, make sure to simmer the cream and butter mixture over low to medium heat until it reduces by 40 to 50% before adding the parmesan.

If you already added the cheese or you bought the sauce at the store, simply pour the sauce into a skillet and set it to simmer.

Step #2: Simmer Until Reduces, Stirring Often

Keep the cream or sauce on the skillet simmering until it gets thick enough. Stir the sauce often to make sure that it does not stick, especially if you have already used the cheese.

Option #2: Use An Egg!

Step #1: Get The Egg

If your sauce is already done and it is not thick enough to cling to the noodles, using an egg might be the perfect solution.

Step #2: Mix Up The Egg

If you are cooking the sauce from scratch, mix the egg and add it to the cream before you start heating it. The egg will help add some thickness to the sauce and help it cling to the noodles.

If you have already cooked your sauce or you bought it from a store, mix the egg up in a bowl with some pasta water and then mix it into the sauce over low heat. Mix constantly to prevent the egg from cooking before it is combined into the sauce.

Step #3: Mix With Noodles & Enjoy!

Now that your sauce is thicker, mix it with the pasta. The egg will help the sauce bind to the noodles giving it a thicker texture.

Option #3: Use More Parmesan!

Step #1: Grate More Parmesan

Parmesan is the key to ensuring that your sauce is thick enough, as it is the only thickening agent used in traditional alfredo sauce. Grate up more parmesan as needed to thicken your sauce.

Step #2: Add In The Parmesan

Add in more Parmesan in ¼ cup increments. Mix thoroughly and allow to sit over heat for five minutes before adding more Parmesan. Check the consistency regularly until you are satisfied with the thickness.

Bonus Tip: What If It Gets Too Thick?

All of these techniques will help your sauce get thicker, but what do you do if your sauce gets too thick?

There’s a secret to this, too! Every pasta lover knows this secret, so I’m going to let you in on it, too.

Make sure that you set aside some pasta water when you’re done cooking your pasta. You can then use the pasta water to thin your sauce if it gets too thick while you are adding in an egg, parmesan, or something else.

Thick Sauce Is Delicious Sauce

Have you learned how to thicken alfredo sauce? It’s pretty easy once you know how. All you need is the sauce and an add-in or two to make sure that your sauce has the time it needs to get thicker.

With a cream sauce like alfredo that doesn’t have any flour in it, the main thing that you should always focus on is making sure you let the cream and butter mixture reduce long enough before you add in any cheese. This is the best time to thicken the sauce, after all!
