Tomato soup is a classic comfort food that warms the hearts and bellies of many. However, one common issue that can detract from its enjoyment is acidity. A soup that’s too acidic can be overwhelming and even uncomfortable to eat. If you’re struggling with acidic tomato soup, don’t worry – you’re not alone. In this article, we’ll explore the reasons behind acidic tomato soup and provide you with practical tips and techniques to reduce its acidity.
Understanding Acidity in Tomato Soup
Before we dive into the solutions, it’s essential to understand why tomato soup can be acidic in the first place. There are several reasons for this:
The Science of Acidity
Tomatoes are naturally acidic, with a pH level of around 4.2. This acidity comes from the high concentration of malic acid and citric acid in the fruit. When you cook tomatoes, the heat breaks down the cell walls, releasing these acids and making the soup more acidic.
Other Contributing Factors
In addition to the natural acidity of tomatoes, other ingredients and cooking methods can contribute to the overall acidity of the soup. These include:
- Tomato variety: Some tomato varieties, like cherry tomatoes or grape tomatoes, are more acidic than others.
- Cooking time and temperature: Cooking tomatoes for an extended period or at high temperatures can break down the cell walls, releasing more acid.
- Added ingredients: Ingredients like onions, garlic, and citrus can add to the overall acidity of the soup.
- Broth or stock: Using a broth or stock that’s high in acidity, such as one made with tomatoes or citrus, can contribute to the acidity of the soup.
Reducing Acidity in Tomato Soup
Now that we understand the reasons behind acidic tomato soup, let’s explore some practical ways to reduce its acidity.
Method 1: Dilution
One of the simplest ways to reduce acidity in tomato soup is to dilute it with a non-acidic ingredient. You can try adding:

- Butter or oil: Adding a small amount of butter or oil can help neutralize the acidity of the soup.
Method 3: Balancing Flavors
Sometimes, acidity in tomato soup can be balanced by adding ingredients that will counteract the acidity. You can try adding:
- Sweet ingredients: Adding a small amount of sugar, honey, or other sweet ingredients can help balance out the acidity.
- Umami ingredients: Adding ingredients high in umami flavor, such as mushrooms or soy sauce, can help balance out the acidity.
Method 4: Cooking Techniques
Finally, you can try adjusting your cooking techniques to reduce the acidity of the soup. You can try:
- Cooking tomatoes for a shorter time: Cooking tomatoes for a shorter period can help reduce the amount of acid released.
- Using a lower cooking temperature: Cooking tomatoes at a lower temperature can help reduce the amount of acid released.
- Adding ingredients at different times: Adding ingredients like onions and garlic towards the end of cooking can help reduce their contribution to the overall acidity.
Additional Tips and Variations
Here are some additional tips and variations to help you reduce acidity in tomato soup:
Roasting Tomatoes
Roasting tomatoes before adding them to the soup can help reduce their acidity. Simply cut the tomatoes in half, toss with olive oil and your choice of aromatics, and roast at 350°F (180°C) for 20-30 minutes.
Using Fresh Herbs
Adding fresh herbs like basil or parsley can help balance out the acidity of the soup. Simply chop the herbs and add them towards the end of cooking.
Making a Roux
Making a roux with butter or oil and flour can help thicken the soup and reduce its acidity. Simply cook the roux for a few minutes before adding the tomatoes and other ingredients.

What causes acidity in tomato soup?
Tomato soup can be acidic due to the natural acidity of tomatoes. Tomatoes contain malic acid and citric acid, which give them their characteristic tangy flavor. However, when tomatoes are cooked, these acids can become concentrated, resulting in a soup that is too acidic. Additionally, other ingredients commonly used in tomato soup, such as onions and garlic, can also contribute to the overall acidity of the dish.
Other factors can also contribute to the acidity of tomato soup, including the type of tomatoes used, the cooking method, and the addition of other acidic ingredients like lemon juice or vinegar. Understanding the sources of acidity in tomato soup is the first step in reducing it and achieving a more balanced flavor.
How can I reduce acidity in tomato soup without losing flavor?
There are several ways to reduce acidity in tomato soup without losing flavor.
