How To Make Fettuccine Sauce Thicker?

You can try a few different things to thicken Alfredo sauce. The first approach is not only the simplest, but possibly the best-tasting as well. Cheese, typically Parmigiano-Reggiano and in large quantities, is the main component in Alfredo sauce. You can add more cheese than is specified in a recipe to thicken alfredo sauce until you have the desired consistency.

How can I thicken and cream up my sauce?

Reducing the liquid in a sauce is the simplest way to thicken it. You can accomplish this by simmering or fully boiling your sauce while leaving the lid off so the steam can escape. Keep in mind that if your sauce is just a tiny bit too thin, this is a good remedy. This isn’t the greatest course of action for a sauce that requires a complete makeover and is quite watery. Consider it like this: By concentrating the flavor while lowering the liquid, you may affect the amount of salt. A sauce that wasn’t intended to be decreased at all could become too salty if it is cut in half. Consider using one of the thickening agents listed below if your sauce requires substantial thickening.

How can flour be used to thicken Alfredo sauce?

Any sauce can be thickened by adding thickening ingredients like starch and egg yolks, whether you’re thickening a thin chili or a sloppy pasta sauce. We’ll also take a look at some uncommon thickeners. Cream sauce and even soups are frequently thickened with roux.

Reducing the Sauce:

The simplest technique to thicken the sauce without flour is perhaps to simply boil off any excess heavy cream or pasta water that you may have added to your sauce. Additionally, since it won’t change the flavor of chilled alfredo sauce, it is a fantastic method for thickening it.

Just bring the sauce to a boil, then turn the heat down, and let it simmer until it thickens. To keep the sauce from burning and sticking to your pan, keep stirring. The alfredo sauce will continue to thicken as it cools, so keep that in mind as well.


The use of flour to thicken sauce is quite typical among chefs. All you have to do is combine a spoon or two of flour with a little water to create a slurry. Stirring continuously, gradually incorporate in this mixture to your Alfredo sauce.

The sauce should be simmered until it has thickened and the flour is completely cooked. This method works well if you’ve already created alfredo sauce using cream cheese and heavy cream and don’t want to add more cheese to thicken it because it won’t make the sauce too heavy.


This ingredient makes sense because bechamel and other white sauces start with a roux basis. This is a fantastic substitute for adding egg yolks or cream cheese if you’re creating a “thin” alfredo meal without heavy cream (or trying to make the real Italian Fettuccine alfredo).

Butter is melted in a skillet and flour is added in a proportional amount to make roux. The flour is then heated through and cooked in the butter for a few minutes, giving off a faint nuttiness. Then the roux from the alfredo sauce is incorporated into the sauce and cooked until it is thick and creamy.

Egg Yolks:

When done correctly, this produces a gorgeously thickened sauce like carbonara. As a result, it pairs particularly well with the straightforward Italian alfredo sauce, which may become overly thick and custard-like when egg yolks are added to heavy cream.

In order to thicken your alfredo sauce without cream, first temper some egg yolks. Beat some yolks until they are smooth and runny to achieve this.

Then, whisking continuously, add a ladle’s worth of your alfredo sauce to the egg yolks. To avoid scrambling the eggs, add the sauce carefully and check that it’s not too hot.

As you keep adding sauce, whisk continuously to ensure that the eggs are fully combined. Continue stirring as you add this mixture to the remaining Alfredo sauce.

The sauce needs to simmer on medium-low heat for a few minutes to thicken. Alfredo sauce can be thickened with eggs if you have gluten intolerance.

Cream Cheese:

As long as you don’t mind your pasta tasting a little acidic, cream cheese is a suitable thickening for American alfredo sauce. It is also a wise choice if you are preparing a parmesan-free alfredo sauce.

Just cut your cream cheese into cubes and give it a little time to soften. Although letting your cheese out for 15 minutes can do, room temperature is preferred. After that, stir the cheese into a hot pot of Alfredo sauce.

This should be done gradually, with a small amount of cheese added at a time. Be patient as it will take some time for the cheese to emulsify and thicken. Additionally, the heat should be kept to low since hot temperatures can cause cheese to “split,” resulting in a gritty and unpleasant sauce.

No cream cheese in your refrigerator? Many of these practical cream cheese replacements are effective.


Like flour, cornstarch works well to thicken most sauces, including those with cream as one ingredient. Here’s how to use cornstarch to thicken a sauce: A couple of spoons of cornstarch whisked with a little water until the mixture was smooth and lump-free.

Then, gradually incorporate this slurry into your alfredo sauce while continuously stirring to prevent the slurry from congealing.

Then, over medium-high heat, gradually whisk the slurry into the simmering Alfredo sauce. As soon as the sauce achieves the required thickness and consistency, continue whisking. Even better, use arrowroot powder, which functions similarly to cornstarch.

Potato flakes work well as a thickening as well. However, avoid using cornmeal because it will partially separate from the sauce and leave it “gritty.”

Shredded Cheese:

Any other type of shredded cheese will work in place of the cream cheese in an alfredo sauce. There is such a thing as mozzarella alfredo sauce, especially when it contains freshly shredded high-moisture mozzarella.

To ensure that the cheese melts easily, avoid buying pre-shredded varieties when using shredded cheese. Instead, shred some high-quality cheese yourself and stir it into the sauce as you gradually add handfuls of it, melting it into the alfredo.

As the cheese melts, the sauce will gradually emulsify and thicken. Use Monterey jack, provolone, or white cheddar for the best results.

Mashed Vegetables:

Mashable starchy veggies are an excellent method to thicken sauce if you want a creamy but nutritious Fettuccine alfredo. Cucumber, leeks, or potatoes that have been boiled can be blended or mashed into a form of puree. If necessary, you can add a little milk to the puree to thin it down.

Then, simply whisk continuously while adding the mashed vegetables to the alfredo sauce in a skillet over heat. The sauce will become considerably creamier as a result of the starch that is produced when the veggies are mashed.

Remember, though, that the completed product will have a taste of the vegetables. While many individuals enjoy the additional flavors, some people prefer to cover up the taste of the cauliflower by adding more cheese and Italian seasoning.

Parmesan Cheese:

Regardless of the type of Alfredo you are preparing, this process works beautifully. Simply grate a brick of parmesan cheese and toss it into the sauce while heating it to medium. The best approach to emulsify the sauce and make it creamy and shiny is to use full-fat cheese.

Since parmesan is already present in the sauce, adding more won’t alter its flavor. Add a little milk or a splash of pasta water to thin out the sauce if you’ve added too much cheese and it’s too thick.

Crushed or Powdered Nuts:

Vegan Alfredo on the menu? Instead of using cheese or eggs as a thickening, you can use crushed almonds.

If you’re attempting to avoid gluten, this is a fantastic alternative. It is extremely adaptable because you can use practically any nut you have on hand, particularly cashew or almonds.

After lightly toasting the nuts until fragrant, grind them into a fine powder in a spice grinder. After that, stir this powder into the Alfredo sauce and boil for a while until it thickens.

Additionally, you can soak the nuts in some hot water and mix the resulting paste to thicken your sauce even more quickly.

Is a heavy Alfredo sauce appropriate?

It is true that an authentic alfredo sauce will thicken as it cools. But alfredo sauce tastes best when it’s hot or at least warm, so keep the heat low until you’re ready to serve, stirring now and then.

A chef’s preference for alfredo sauce thickness is entirely arbitrary. Some people want it a little bit thin, while others prefer it excessively thick.

The most important thing is that the pasta be completely covered in alfredo sauce.

How can I thicken my Alfredo sauce?

First, cream cheese

When the cream cheese is smooth, cube it and stir it into the Alfredo Sauce in a pot over heat. Be patient as it could take a short while for the cream cheese to melt and become creamy. Unless you don’t mind a heavier cream cheese flavor, start out with a small amount at a time.

Parmesan cheese, 2.

Add some freshly grated Parmesan cheese of a high caliber to the sauce. Your best bet in this case is freshly grated full-fat Parmesan cheese. I enjoy purchasing a large block of Parmesan from Costco and grating it by hand. If you understand what I mean, it works MUCH better than anything you would find already grated in the spaghetti section of the grocery store shelf.

3. Diced Cheese

It can also be effective to whisk in some high-quality cheese that you have grated yourself. If necessary, you could utilize pre-shredded meat, but pre-shredded meat doesn’t often melt well in sauces, so stick with a name brand. If possible, use a box grater or food processor to shred your own cheese. Depending on your preferences, you should try mozzarella, provolone, or even white cheddar.

4. Cream of Heavy

In a saucepan over medium heat, whisk a small amount of heavy cream into the sauce and cook until it simmers or thickens slightly. Though it can take a lot of cream to thicken a lot of sauce, it’s not always the best solution.

Fifth, cornstarch (or Arrowroot)

Make a slurry by combining a little amount of cornstarch with some cold water (or another liquid) in a small bowl. Pour the slurry into the boiling sauce in a skillet over medium-high heat and stir slowly. Until the spicy sauce has the correct thickness, slowly whisk in the slurry.

6. Flour

In a small bowl, combine some flour with a little water and whisk until smooth, just as you would with cornstarch. While the sauce is cooking in a pan, gradually whisk the flour mixture into the sauce.

Seven. Egg yolks

Be careful with this one so your sauce doesn’t contain scrambled eggs! In a small bowl, place one or more egg yolks (or more, depending on how much sauce you have…). Add a little spicy sauce to the eggs while you whisk them. More hot sauce should be whisked into the yolks until they have absorbed a sizable amount of the sauce and the eggs are heated. The yolks are then incorporated into the spicy sauce-filled skillet. You won’t get smooth curdled eggs if you simply whisk cold egg yolks into hot sauce. Done that, been there, not good.

8. Produce

You read that correctly; Some veggies can be pureed and then added to the sauce. Cauliflower that has been cooked and pureed (like by steaming…) would be fantastic! So long as you don’t mind the flavor of vegetables in your sauce.

9. Roux

Over medium heat, melt some butter; after it has melted, stir in the same amount of flour. Butter and flour should be smoothed out by whisking. In a pan over medium heat, whisk a small amount of the roux into the sauce that is simmering.

Butter 10.

Similar to the roux, add equal quantities of softened butter and flour in a small bowl and stir until the mixture resembles paste. To thicken a simmering sauce, whisk in a small amount at a time.

Which one do I prefer then? If I had to choose one, I would start by trying to add more grated Parmesan cheese. I think it would taste the nicest and be quick and simple.

What makes spaghetti sauce thicken?

Add the flour to the saucepan when the butter has melted, then whisk the mixture.

After the roux has cooked for one to two minutes, mix it into the pasta sauce (be sure the pasta sauce is warm).

Pasta sauce should start to thicken rapidly after being brought to a gentle heat.

Cornstarch Slurry

Pasta sauce should be blended with the cornstarch slurry (be sure the pasta sauce is warm).

The pasta sauce should soon thicken after being brought to a low simmer.

Starchy Pasta Water

Before straining the pasta after cooking it for your spaghetti sauce, drain 1 cup of the starchy pasta water from the saucepan.

Start by adding 1/4 cup of pasta water to your spaghetti sauce in order to thicken it.

Pasta sauce should be whisked into the starchy pasta water before being gently simmered.

If the sauce isn’t as thick as you’d like, continue adding 1 spoonful at a time of starchy pasta water to the sauce until it is.

How may a heavy cream sauce be thickened?

The rich, thick portion of milk that rises to the top is known as heavy cream or heavy whipping cream. When compared to other dairy products, it has one of the highest fat concentrations. Due to its rich flavor, heavy cream is frequently used in baking or cooking. It includes roughly 36-40% milk fat.

They aren’t the same, no. Whipping cream only comprises roughly 30% fat compared to heavy cream’s 36–40% fat level. Heavy cream is thicker and holds its shape better as a result.

Heavy cream can be thickened in a variety of methods, including by whisking, reducing, adding gelatin, flour, cornstarch, guar gum, or combining with cream cheese, among others.

One method to thicken cream is to reduce heavy cream on the stove. You should gently bring it to a boil while whisking continuously, then reduce the heat so that you can sustain an active simmer for a few minutes.

Yes, you may reduce heavy cream on the stovetop to get a rich, creamy foundation.

As you heat the heavy cream, it will thicken, a process known as boiling or reducing. The finished product will gradually grow thicker the longer the cream is heated since more liquid will eventually evaporate.

Not freezing your heavy cream and whisking tools is one of the most frequent errors that prevents heavy cream from thickening. The optimum texture is ensured by using them cold.
