    Are tomato soups keto-friendly?

    Store-bought tomato soup is loaded with carbs and is not keto-friendly, so you have to make it yourself. It also depends on how you make it. While tomatoes are a low carb vegetable, the carbs do add up pretty quickly.

    The serving of this creamy tomato soup is small to keep the carbs low, but if you eat two or more servings, you could use up all your carb allotment for the day.

    Here are the simple ingredients you need for this low carb tomato soup recipe.

    ingredient list of tomatoes, heavy whipping cream and spices
    • Roma tomatoes: I like to use fresh tomatoes, but you can use diced tomatoes. Tomatoes are a bit acidic, but I find that sautéing them for a bit cuts down on the acidity.
    • Chicken broth: This helps to enhance the flavor of the soup. If you don't have chicken stock, you can use water but add more spices.
    • Heavy whipping cream: This makes the tomato soup really creamy and adds bulk to it. You can also use unsweetened, full-fat coconut milk or coconut cream.
    • Onions and garlic: To make it more flavorful.
    • Spices: Smoked paprika, black pepper, cumin, cayenne pepper, and salt.
    • Herbs: Herbs bring out another dimension of flavor to this keto tomato soup. You can use cilantro, fresh basil, or parsley.
    • Olive oil: For sautéing. You can also use avocado oil or coconut oil.

    How To Make This Recipe

    Here's how to make this easy keto tomato soup recipe.

    • Chop the onions and tomatoes, and mince the garlic. Sauté onions and garlic in olive oil till translucent.
    • Add the chopped tomatoes and bring them to a boil. Add black pepper, cayenne pepper, smoked paprika, cumin, and stir.
    • Simmer on medium heat for 5 minutes. Add one cup of broth and cook for 10 minutes, or till the tomatoes no longer taste sour.
    • Add another cup of water and the heavy cream and mix together.
    • Pour into a blender and puree until it's smooth. Pour the soup back into a pot and adjust the seasoning if you wish. I always add salt last because broth contains some salt.
    • Simmer till you reach your desired consistency.

    How can I thicken my homemade soup?

    Usually, letting the homemade tomato soup simmer on the stove for a few minutes will make it thicker. But if you're in a hurry, you can make a slurry.

    Mix half a teaspoon of arrowroot powder and a tablespoon of water in a bowl. Pour into the soup and mix together. In about a minute or so, your soup will begin to thicken.

    If you need to know about the various keto and low carb thickeners out there, this article is a good place to start.

    Storing and reheating

    Allow the soup to get to room temperature and store it in an airtight container in the fridge for up to 4 days. Reheat on the stove for best results.

    Tips and variations

    • Cayenne pepper is optional if you don't like it spicy, but it helps cut down on the acidity of the tomatoes.
    • Another alternative to help with the acidity is by adding a low-carb sweetener like monk fruit sweetener, stevia, or allulose.
    • Use fire-roasted tomatoes for a stronger, smoky flavor.
    • If you don't want to use a regular blender, you can use an immersion blender instead to blend your soup.
    • You can also coarsely blend the soup to make it chunkier if that's what you prefer.
    • For more creaminess, add some cream cheese or a dollop of sour cream.

    Frequently Asked Questions

    Why is tomato soup so high in carbs?

    Tomato soup is high in carbs because the carbs in tomatoes add up pretty quickly. One tomato contains 4.8g of carbs, and a serving of tomato soup can easily contain a few tomatoes since it thickens up when cooking.

    Can you eat tomato soup on the keto diet?

    It depends. Store-bought tomato soup can easily contain a lot of carbs which might kick you out of ketosis. The best way to enjoy tomato soup on your keto diet is to make it yourself so you can have more control over your carb intake.

    Is tomato soup the same as tomato puree?

    No, it is not. Tomato puree is a mix of tomato paste, water, and some other ingredients and preservatives. Tomato soup has been cooked with other ingredients and usually has more flavor. It has less liquid and is a bit thicker than tomato puree.

      Thank you! I have been looking for a great recipe complete with seasonings, and the first five or so popped up with herbs de provance in it. Who does that? Nobody really like lavender in their tomato soup.
      This was almost perfect, with the smoked paprika? Heaven.
      I'm looking forward to more of your recipes.
