Understanding the Carb Count in Tomato Soup
When you prepare canned tomato soup with milk, you're not just adding creaminess; you're also adding to the carbohydrate content. Canned condensed tomato soup typically has added sugars to balance the tomato's acidity, which contributes to its carb total. When you mix in milk, particularly dairy milk, you add more carbohydrates in the form of lactose, which is milk's natural sugar. Different preparations and types of milk will result in different final carbohydrate counts.
For example, a standard 10.75-ounce can of condensed tomato soup, like Campbell's, is meant to be combined with an equal amount of liquid, such as a full can of milk. Since a 1-cup serving (roughly half the prepared can) has about 25 grams of carbohydrates, consuming the whole prepared can would mean a significantly higher intake. It's crucial to check specific nutritional labels, as formulations can differ greatly between brands.
Factors Affecting Carb Content
Several key factors influence the number of carbohydrates in a bowl of tomato soup prepared with milk:
- Type of Milk: Whole milk adds more fat but has similar lactose content to 2% or skim milk. Plant-based alternatives like almond or coconut milk typically have much lower carbohydrate counts and can reduce the overall total. For instance, unsweetened almond milk has a negligible amount of carbs, whereas standard dairy milk contains about 12 grams of carbs per cup.
- Canned Soup Variety: Not all canned tomato soups are created equal. "Cream of Tomato" soup, for example, is pre-formulated with a cream base and may have a higher or different carbohydrate profile than standard condensed tomato soup mixed with milk at home. Some brands also offer low-sodium or reduced-sugar varieties that will affect the total carb load.
- Added Ingredients: Many recipes call for additional ingredients to enhance the flavor. Adding a tablespoon of flour or sugar to thicken or sweeten the soup will, of course, increase the carb count. Toppings like croutons, crackers, or cheese can also contribute a surprising number of extra carbs.
Comparison Table: Milk vs. Water Preparation
To illustrate the impact of adding milk, here is a comparison of typical nutrition facts for a single-serving of prepared condensed tomato soup.
| Nutrient (per 1 cup) | Prepared with Water | Prepared with 2% Milk |
|---|---|---|
| Total Carbohydrates | ~17g | ~25g |
| Net Carbs | ~15g | ~23g |
| Sugars | ~9g | ~17g |
| Protein | ~2g | ~6g |
| Fat | <1g | ~3g |
| Calories | ~76 | ~139 |
As the table shows, preparing the soup with 2% milk adds a significant amount of carbs, mainly due to the lactose and extra calories. The protein and fat also increase, contributing to a creamier, more filling final product.
How to Reduce Carbs in Your Creamy Tomato Soup
If you're watching your carbohydrate intake, there are simple adjustments you can make without sacrificing flavor:
- Use Heavy Cream: For a keto or low-carb approach, heavy cream is an excellent choice. It has very few carbs per serving and adds a rich, decadent texture, making it a better option than dairy milk for those on a low-carb diet.
- Opt for Low-Carb Milk Alternatives: As mentioned, unsweetened almond or coconut milk can dramatically lower the carb count. They offer creaminess without the lactose. You can also thicken the soup with a small amount of low-carb thickener like xanthan gum if needed.
- Choose a Low-Sugar Soup Base: Look for canned tomato products with no added sugars. Canned crushed tomatoes or tomato puree are great bases for a homemade, low-carb soup. You can then control the added ingredients entirely.
- Make Your Own Soup: A homemade tomato soup from scratch gives you complete control over the ingredients. A simple recipe with fresh tomatoes, vegetable broth, and heavy cream can be very low in carbs. Seasoning with herbs and spices instead of added sugar will help reduce the carb load.
Conclusion
In summary, a single 1-cup serving of canned tomato soup prepared with milk typically contains around 25 grams of carbohydrates. This is considerably higher than the same soup made with water and is primarily due to the natural sugars in milk and the added sugars often found in condensed soup mixes. The choice of milk, specific brand, and any additional ingredients will cause this number to fluctuate. For those following a low-carb or keto diet, switching to heavy cream or a low-carb milk alternative and choosing a low-sugar tomato base are effective strategies to significantly reduce the carb count while still enjoying a creamy, comforting bowl of tomato soup.

Frequently Asked Questions
What is the difference in carbs between tomato soup with milk vs. water?
Adding milk significantly increases the total carbohydrate count. A 1-cup serving of condensed tomato soup prepared with water has approximately 17g of carbs, while the same soup prepared with 2% milk has around 25g.
Is canned tomato soup prepared with milk a good low-carb meal?
No, canned tomato soup with milk is not typically considered a low-carb meal due to the high sugar content in many condensed soups and the lactose in dairy milk. For a low-carb version, it's best to use heavy cream or a low-carb milk alternative and start with a low-sugar tomato base.
Does using fat-free milk reduce the carbs in tomato soup?
Using fat-free milk will not significantly reduce the carbohydrate count compared to 2% or whole milk. The carbohydrates in dairy milk come from lactose, and the amount is fairly consistent across different fat percentages.
Why does canned tomato soup have so many carbs?
Canned tomato soup, especially condensed varieties, contains a notable amount of sugar. This added sugar helps to balance the acidity of the tomatoes and contributes significantly to the overall carbohydrate content.
Can I make a creamy low-carb tomato soup at home?
Yes, you can easily make a low-carb version at home. Use a base of canned unsweetened crushed tomatoes, vegetable or bone broth, and heavy cream instead of milk. For flavoring, rely on herbs and spices rather than sugar.
Is there a specific brand of tomato soup that is lower in carbs?
Some brands offer low-sodium or organic tomato soups that may have less added sugar. However, the best way to find a truly low-carb option is to look for recipes that use a high-quality tomato base and low-carb thickeners or creams, as most standard condensed soups contain added sugars.
Does heavy cream add many carbs to tomato soup?
No, heavy cream is very low in carbohydrates, making it an ideal choice for making creamy, rich soups on a low-carb or ketogenic diet. It will add fat and calories but minimal carbs.
