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

• 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 Keto Tomato Soup

• Chop the onions and tomatoes and mince the garlic. Sauté the onions and garlic in olive oil until translucent.
• Add the chopped tomatoes, then add the spices 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 the soup into a blender and puree until 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 keto tomato soup?

Usually, letting the homemade tomato soup simmer on the stove for a few minutes thickens it. 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.

Storing and reheating

Allow the soup to reach room temperature, then 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 reduce the tomatoes’ acidity.
• Another alternative to help with the acidity is to add a low-carb sweetener, such as monk fruit, stevia, or allulose.
• Use fire-roasted tomatoes for a stronger, smoky flavor.
• If you don’t want to use a regular blender, you can blend your soup using an immersion blender.
• You can also coarsely blend the soup to make it chunkier if that’s what you prefer.
• Add some cream cheese or a dollop of sour cream for more creaminess.
