How to Substitute for Tomato Soup (Even If You Don’t Like Tomatoes)

Finding a substitute for tomato soup is not as difficult as you may think.  At its core, tomato soup consists of a few basic ingredients.  There are also plenty of tomato soup substitute options that are completely tomato-free. 

The best substitute for tomato soup depends on your goals, and what ingredients you have on hand.  If you have tomato products on hand then you can make homemade tomato sauce from scratch, and build your soup recipe from there.  Otherwise, for a tomato-free option consider the carrot marinara recipe below or a squash-based vegetable puree.  

Core Ingredients for a Tomato Soup Substitute:

  • Any form of tomatoes (fresh tomato, tomato juice, tomato paste)
  • Salt
  • Sugar
  • Corn Starch

If you have these core ingredients on hand, you can make a substitute for tomato soup at home that will work in a pinch.  Using any form of tomatoes, you’ll need to first create the tomato sauce.

What if you don’t have any tomato Sauce?

If you have just run out of tomato sauce, but you have some other tomato products on hand, don’t lose heart!  

While the flavor you end up with may be a little different than store-bought tomato sauce, it’s relatively simple to make your own tomato sauce from scratch. If nothing else, making tomato sauce from scratch can save you a trip to the store by using ingredients that you have on hand.  

You can substitute fresh tomatoes, tomato paste, or even tomato juice as described below.

Fresh Tomatoes:

You can easily substitute diced fresh tomato to create a homemade tomato puree. Sautee your diced tomatoes on low heat until they begin to break down in the pan.  

Use a potato masher,  spoon, or fork to puree the tomatoes they break down during cooking.  Add your favorite seasonings to improve taste and overall quality. 

Tomato Juice:

In a pinch, you can even boil tomato juice down to form a thicker sauce. Then add a few common seasonings as mentioned below.  

Tomato Paste:

Finally, if you happen to have tomato paste on hand, just add some water, stir, and simmer until the consistency becomes similar to that of store-bought tomato paste.   Season lightly to taste, and set your homemade tomato sauce aside to use later in your tomato soup recipe.  

Ingredients for Homemade Tomato Soup:

  • 8 oz Tomato Sauce (or a similar tomato-based product)
  • 1 Tablespoon Corn Starch
  • 1-2 Tablespoons Sugar (white or brown)
  • ½ teaspoon Salt
  • ½ cup heavy cream (optional)
  • ½ cup water (optional)

Directions:

Simply combine all ingredients in a bowl, and whisk thoroughly.  For a creamier soup, you may also add 1 cup of liquid such as milk, water, or a combination of both.  Warm the thoroughly mixed ingredients in an appropriately sized pot on the stove and season to taste. 

Season to Taste:

Apart from salt, you may wish to add a variety of different seasonings to improve the taste and quality of your homemade tomato soup substitute.  Whether or not you wish to add more seasoning largely depends on how your tomato soup substitute will be used.

If tomato soup is simply a subset of a more complex recipe, then you probably don’t need to add any additional seasoning.  

On the other hand, if you plan to serve your tomato soup substitute by itself, then you may wish to add more ingredients to improve the taste and quality.
