The internet is simply flooded with various sauces for spaghetti and the most reliable ones are from Italian, French and even English cuisines. It needs to be added that the ones from the American cuisine are not so reliable. In most of the times, those recipes lack one and the same think – thickening the sauce, and there is not a good explanation of how to do it. The spaghetti sauce can be considered as an American invention to some extent.
How to thicken it?
There is not so much science in this since there are two simple ways in which a person should thicken a spaghetti sauce. The first one is to reduce liquid in it and the second one is to simply add starch. How to reduce liquid? Well, first of all, when you start with the preparation of the sauce, you can simply add less liquid into it. Furthermore, there is also the option of actually boiling the liquid off during the course of the preparation of the sauce. Finally, you can simply use some kind of a thicker liquid, e.g. water. When starch is in question, it is pretty simple, you can use some of these ingredients: flour, breadcrumbs, mashed potatoes, cornstarch etc.

However, in most of the cases, it would be needed to apply both these techniques, i.e. reducing water and adding starch, at the same time to get a good result. However, there is also a third thing that can be used in order to make a spaghetti sauce a bit thicker and it is using tomato paste. In this way, you would increase the amount of tomato to the sauce you would make, but you would not increase the liquid in the sauce you are making.
Tomato Sauce
As we have said, this sauce is among the essentials for the preparation of a good spaghetti sauce, and it is one of the inseparable ingredients to it. So, how to make it thicker? Let’s see.
- The first thing you can do is actually to set the pasta water aside, and later to use the same water for the preparation of the sauce. The reason for this is the fact that there is already a lot of starch in this water, which is great for thickening.
- If you decide to add cornstarch, you are on the right track. The reason for this is the fact that cornstarch has a neutral flavor and will not thus disturb the taste you want to achieve.
- Prepare and add a roux. What is it? In essence, a roux is the mixture of fat and people prepare it by cooking it in the combination with flour and butter. This is one of the most common way so thickening the sauce.
- If you want to make things even more interesting, mash some potatoes and add them to the sauce, and it would be perfectly thick.
- One of the best techniques is actually simmering and this would leave the sauce to thicken by itself through the process of cooking.
