Naturally, tomatoes are acidic vegetables with a pH of about 4.6. Hence, having tomato soup that tastes acidic (sour) is common, especially when one knows next to nothing about the different varieties of tomatoes.
Some tomatoes have high sugar content and are sweet enough to eat off the vine, while others have low sugar content with more pronounced acidity. The sweet tomato varieties include Sungold tomato, Cherry tomato, and Campari tomato.
Since your tomato soup is mainly dependent on the base ingredient: tomato, the variety used determines if you’ll have a more acidic or less acidic tomato soup. However, you can reduce the sourness and make tomato soup less acidic by adding some other ingredients. This article reviews how to make tomato soup less acidic.
How to Make Tomato Soup Less Acidic?
Here are a few methods to apply to prevent that acidic taste in your tomato soup:
Add baking soda
To make tomato soup less acidic, use baking soda. Baking soda is naturally basic (or alkaline) with a pH of about 9. Hence, when you add baking soda to your tomato soup, the alkaline baking soda will neutralize the acidic tomatoes, removing the sourness and make your soup taste less acidic.
However, note that you must be careful not to add too much baking soda to your tomato soup to avoid ruining the flavor and food poisoning. Typically, adding about 1/4 of a teaspoon of baking soda will completely neutralize the acid in your tomato soup.
Add herbs and spices
Fresh or dried herbs such as basil or sage and spices such as garlic can also help to make your tomato soup less acidic. For example, you can sauté two or more garlic cloves (as desired) in olive oil before adding crushed or pureed tomatoes. Garlic will impart its aromatic flavor to your sauce, making it taste less acidic (sour). You can also top it with some basil or another herb.
Adding vegetables like onions, carrots, and celery will add a sweet aromatic flavor to your tomato soup, making it less acidic.
First, you can try sautéing some onions in olive oil; next, add some diced carrots and chopped celery, then pour in your crushed tomatoes and allow it to cook.
Alternatively, you can use sofrito as a base for your tomato soup. A sofrito already has onions, peppers, and garlic added to some tomatoes. So, you can start with a sofrito and then add your crushed or pureed tomatoes to it. That way, they mix, and the spices in the sofrito reduce the acidity of your tomato soup.

How to keep milk from curdling in tomato soup
There is a great tendency that milk in tomato soup will curdle because tomato soup has everything needed for milk to curdle; an acidic environment and heat. So here are some tips to keep milk from curdling in your tomato soup.
- Do not use skimmed or low-fat milk. The higher the fat content of the milk, the lesser the chance of curdling.
- Add a thin flour and water paste to the milk. This will help thicken the soup and prevent the milk from curdling.
- Do not boil your soup after adding milk or dairy products; the high temperature will make the milk curdle. Instead, add the milk gradually to the soup, warming it slowly.
- Heat tomato soup containing milk slowly on low heat.
- Add a little baking soda to your tomato soup to help neutralize the acid entirely so that the milk does not curdle.
Why does my tomato soup have white spots?

Add more base ingredients
This technique is based on an increase in volume. Adding more tomatoes, peppers, stock, or any base ingredient you used for your spaghetti sauce will help cut the sweetness, and you will even have more sauce that you can save for later. If you used the sweet variety of tomatoes as a base ingredient, this method might not be effective.
Add counteractive ingredients
Another effective way of cutting sweetness in spaghetti sauce is by adding ingredients to counteract that sweetness. For example, acidic ingredients like vinegar, lemon juice, and lime juice will reduce the sweetness of your sauce when added in small amounts. Other counteractive ingredients you can add are cooked mushrooms and spices like chili peppers or paprika.

How do you stop heartburn from tomato sauce?
Heartburn is one of the major reasons why the need to make tomato soup less acidic arises. If you have acid reflux symptoms or gastroesophageal reflux disease (GERD) or are sensitive to acidic foods, you may experience heartburn after eating tomato sauce. You can stop heartburn from tomato sauce by:
- Drinking lots of water to dilute the stomach acid.
- Raising your upper body or standing up straight.
- Eating alkaline foods such as bananas or melons.
- Taking over-the-counter (OTC) heartburn drugs.
- Reducing the acid in your tomato sauce.
If you have additional symptoms such as difficulty in swallowing or chest pain alongside heartburn, please see your doctor for proper diagnosis and treatments.
How to tame acid reflux
Acid reflux symptoms worsen when its victim eats certain foods known as “trigger foods.” Trigger foods are mostly acidic foods such as tomatoes which increase the acidity of the stomach’s content.
As a result, the victim’s lower esophageal sphincter (the valve at the end of the esophagus) is weakened. Thus, there is a backwash of the acidic content of the stomach into the esophagus. This allows the stomach content to flow from the esophagus into the throat and mouth, giving an unpleasant, sour taste in the mouth and causing heartburn. This adds up to why we need to make tomato soup less acidic.
If you suffer from acid reflux, there are three major ways you can tame it. These include:
- Dietary changes.
- Lifestyle changes.
- Use of over-the-counter (OTC) and prescription medications.
Your diet is the first point of consideration when trying to tame acid reflux, especially since those symptoms occur mostly after a meal.
So first, find out what you eat that triggers acid reflux. These trigger foods include acidic foods like tomatoes, gas-forming foods like beans, fatty foods like fries, spicy foods, and caffeinated or carbonated beverages.
Trigger foods vary for each individual. Once you discover your trigger foods, fine-tune your diet to include foods that do not cause problems for you and exclude those that cause a flare-up. For example, while carbonated and caffeinated drinks are not healthy and can be eliminated from the diet, other foods like beans and tomatoes contain essential nutrients. Therefore, they should either be substituted or eaten in small quantities.
Certain lifestyle factors such as smoking, obesity, poor sleep quality, etc., can cause acid reflux or worsen symptoms of acid reflux. For example, Johns Hopkins Medicine reports that smoking weakens the esophageal sphincter, allowing the stomach’s acidic contents to flow back into the esophagus.
Here are some lifestyle modifications that help to tame acid reflux:
- Quit smoking.
- Lose weight
- Avoid stress and anxiety.
- Eat smaller meals at intervals throughout the day.
- Stay up for 1-2 hours after eating; do not lie down immediately after a meal.
- Do not eat late at night.
- Sleep placing your upper body higher than your lower body.
Use of over-the-counter (otc) and prescription medications
If your acid reflux symptoms do not reduce with diet and lifestyle changes, see your healthcare provider for drug prescriptions. There are several OTC heartburn medications and antacids that help to relieve heartburn and other acid reflux symptoms.
Note: Chronic acid reflux (GERD) requires immediate medical intervention as it could lead to more serious medical conditions.
