Have you ever found yourself with a pot of spaghetti sauce that’s just a little too thin for your liking? Don’t worry, there are plenty of ingredients you can use to thicken it up and give it that perfect consistency. In this article, we’ll explore some of the best options for thickening spaghetti sauce and enhancing its flavor.

Tomato Paste

If you’re looking for a natural and easy way to thicken your spaghetti sauce, tomato paste is the way to go. It’s concentrated tomato puree that adds both thickness and intense flavor to any sauce. Simply stir in a tablespoon or two of tomato paste into your simmering sauce until it reaches the desired consistency.


Another great thickening agent for spaghetti sauce is breadcrumbs. They not only add thickness but also help absorb excess liquid and enhance the texture of the sauce.

To use breadcrumbs, start by adding a small amount to your sauce and let it simmer for a few minutes. If needed, add more until you achieve the desired thickness.

Cornstarch or Arrowroot Powder

If you prefer gluten-free options, cornstarch or arrowroot powder are excellent choices for thickening spaghetti sauce. Mix either of these powders with water to create a slurry before adding it to your simmering sauce. Stir well and continue cooking until the sauce thickens.


Adding cheese not only brings extra flavor but also acts as a thickener for your spaghetti sauce. Parmesan cheese is particularly effective due to its low moisture content and strong flavor profile. Grate some Parmesan cheese into your simmering sauce and stir until melted and well incorporated.


If you prefer natural thickeners, some vegetables can do the job beautifully. Onions, mushrooms, and bell peppers are great options.

Sauté these vegetables before adding them to your sauce to release their flavors and enhance the thickness. You can either finely chop them or puree them for a smoother sauce.


While adding thickening agents is helpful, sometimes all you need is a little patience. Simmering your spaghetti sauce for an extended period allows the moisture to evaporate, resulting in a thicker sauce. Just make sure to stir occasionally to prevent it from sticking to the bottom of the pot.

Final Thoughts

Thickening spaghetti sauce doesn’t have to be complicated. Whether you opt for tomato paste, breadcrumbs, cornstarch, cheese, vegetables, or simply simmering it down, there are plenty of options available to suit your preferences.

Experiment with different methods and find what works best for you. Enjoy your delicious homemade spaghetti sauce with the perfect consistency!
