It seems impossible to create such a delicious homemade tomato soup starting with basic canned whole tomatoes, but this soup builds so many layers of flavor in just 25 minutes.

Once you try this tomato soup, you’ll wonder where it’s been your whole life.

While you can easily find peeled canned tomatoes at a grocery store, if you are a gardener, check out this post on canning whole tomatoes.

And to make this dinner even faster, prep by freezing onions and freezing chopped garlic. You won’t regret having these ingredients ready to go in your freezer for all kinds of delicious meals.

Serve this soup alongside some Air Fryer Texas Toast, and your life is about to get amazing.

You can sub in olive oil or non-dairy butter for the ghee.

Pro Tips/Recipe Notes:

  • The baking soda neutralizes the acidity of the tomatoes without using sugar. It evens out the flavor in a really cool way. I highly recommend trying it!
  • This soup freezes like a boss! Freeze in pint wide mouth canning jars for single-servings, and quart jars for family portions. Make sure you leave 1 inch of headspace (space between the top of the food and the top of the jar) to allow for the soup to expand while freezing. Or, try these Souper Cubes for a glass-free option.
  • You can pump up the flavor by adding a few tablespoons of homemade tomato powder.
  • If you want to use fresh tomatoes, check out this post on how to blanch and peel tomatoes.
  • Top each serving with Fried Shallots to take this recipe to the next level.

  • In a heavy-bottomed saucepan, add the olive oil or butter over medium heat. Stir in the onion and allow it to cook down for 3-4 minutes.
    2 tbsp ghee or olive oil, 1/2 onion
  • Add the garlic, and stir for another 2 minutes.
    5 cloves garlic

  • Add the stock, milk, smoked paprika, parsley, basil, and oregano. Bring to a low boil, stirring the whole time.
    1 cup stock, 1/2 cup non-dairy milk, 1 tsp smoked paprika, 1/2 tsp dried parsley, 1/2 tsp dried oregano, 1 tsp dried basil
  • Using an immersion blender, blend the soup to your desired consistency.
  • Once blended, add the baking soda and stir to combine. Finish with a drizzle of balsamic vinegar.
    1/8 tsp baking soda, salt and pepper to taste, balsamic vinegar


If you don't have an immersion blender, carefully transfer the hot soup to a blender. Leave the center cap on the lid off to allow the steam to release.
You'll notice a bit of foaming action with the baking soda; totally normal.

  1. Perfect store cupboard soup that tastes as good as if it had been made from fresh tomatoes!5 stars

  2. Story time: Our house is a house divided when it comes to tomato soup and grilled cheese sandwich night. My husband is a big supporter of the toasted cheese and “real canned tomato soup”, while I am a butter both sides of the bread and grill that sandwich and have it with the most fake orange soup with the mushiest rice in the world. It is about nostalgia for both of us and we have even had conversations about what we will end up giving our future children when neither of us would budge. The answer: this soup. The smokey paprika adds amazing flavor and the baking soda is the answer to all of my issues with adding sugar to tomato soup. My husband loves how fast it is and said it would be a great staple in the regular soup rotation. Thank you Sarah for helping to end this 11 year stalemate.5 stars

    1. I am truly honored to have helped broker this level of peace accords in a house divided. If only soup could heal the world!

  3. I had to do some tweeking to the recipe.  I added a small amount of stevia and a splash of lemon juice as well as more of the spices. It was excellent and because of my dairy and gluten allergy I had not had tomato soup in a long time. I really enjoyed this as did my husband and our family friend
