Tomato sauce and tomato paste are two staples in many cuisines around the world. While they share a common ingredient – tomatoes – they serve different purposes and have distinct textures and flavors. Tomato sauce is a liquid or semi-liquid condiment made from cooked tomatoes, often used as a base for pasta dishes, pizza, and other recipes. On the other hand, tomato paste is a concentrated, thick paste made from reduced tomatoes, used to add depth and intensity to various dishes. But can you turn tomato sauce into tomato paste? In this article, we’ll explore the possibilities and limitations of transforming tomato sauce into tomato paste.
Understanding the Basics of Tomato Sauce and Tomato Paste
Before we dive into the process of converting tomato sauce into tomato paste, it’s essential to understand the fundamental differences between the two. Tomato sauce is typically made by cooking down fresh or canned tomatoes with aromatics, herbs, and spices. The resulting sauce can range from thin and watery to thick and chunky, depending on the desired consistency and recipe.
Tomato paste, on the other hand, is made by reducing tomatoes to a concentrated, paste-like consistency. This process involves cooking the tomatoes for an extended period, removing excess water, and then blending or straining the mixture to create a smooth, thick paste. Tomato paste is often used as a flavor enhancer, adding a rich, intense tomato flavor to dishes without the need for added liquid.
The Science Behind Reducing Tomato Sauce
To turn tomato sauce into tomato paste, you need to reduce the liquid content of the sauce while preserving the flavor and nutrients of the tomatoes. This process involves evaporation, where the water content of the sauce is slowly cooked off, leaving behind a thicker, more concentrated mixture.
There are several factors to consider when reducing tomato sauce:
- Temperature: Heat plays a crucial role in reducing tomato sauce. A gentle heat will help to evaporate the water content without burning or caramelizing the sugars in the tomatoes.
- Time: The longer you cook the tomato sauce, the thicker it will become. However, prolonged cooking can also lead to a loss of flavor and nutrients.
- Stirring: Regular stirring is necessary to prevent scorching and ensure even reduction.
Methods for Converting Tomato Sauce to Tomato Paste
There are several methods to convert tomato sauce into tomato paste, each with its advantages and disadvantages.
Stovetop Reduction
One of the simplest methods for reducing tomato sauce is to simmer it on the stovetop. This involves cooking the sauce over low-medium heat, stirring occasionally, until the desired consistency is reached.
- Pros: Quick and easy, stovetop reduction allows for easy monitoring of the sauce’s consistency.

Oven Reduction
Another method for reducing tomato sauce is to cook it in the oven. This involves transferring the sauce to a baking dish and cooking it at a low temperature (around 300°F/150°C) for an extended period.
- Pros: Oven reduction allows for hands-off cooking, reducing the risk of scorching or burning.
- Cons: Requires longer cooking times, and there’s a risk of over-reducing the sauce.
Dehydrator Method
A dehydrator can be used to reduce tomato sauce to a paste-like consistency. This involves spreading the sauce onto dehydrator sheets and cooking it at a low temperature (around 135°F/57°C) for several hours.
- Pros: Dehydrator method allows for precise temperature control and even drying.
- Cons: Requires a dehydrator, and the process can be time-consuming.
Tips and Variations for Making Tomato Paste from Tomato Sauce
When converting tomato sauce to tomato paste, there are several tips and variations to keep in mind:
- Use a roux: Mixing a small amount of roux (flour and fat) into the tomato sauce can help thicken it and create a more paste-like consistency.
- Add aromatics: Sauteing aromatics like onions, garlic, and herbs can add depth and complexity to the tomato paste.
- Use different types of tomatoes: Experimenting with different tomato varieties, such as cherry or plum tomatoes, can create unique flavor profiles.
- Blend or strain: Blending or straining the reduced tomato sauce can help create a smooth, even paste.
Common Challenges and Solutions
When converting tomato sauce to tomato paste, you may encounter several challenges. Here are some common issues and solutions:
- Scorching or burning: Stir the sauce regularly, and adjust the heat as needed to prevent scorching.
- Over-reducing: Monitor the sauce’s consistency closely, and remove it from heat when it reaches the desired thickness.
- Lack of flavor: Add aromatics, herbs, or spices to enhance the flavor of the tomato paste.
