Ingredients and substitutions
- Olive oil - Can be substituted with your favorite cooking oil.
- Onions and garlic - These add savory flavor to your soup. I don't recommend omitting either ingredient.
- Crushed tomatoes - One can of crushed tomatoes can be substituted with an equal weight of fresh garden tomatoes if desired. Your soup may need to cook down a little longer if using fresh tomatoes.
- Broth - Vegetable broth can be substituted with chicken broth if desired. Keep in mind that the recipe will no longer be vegan.
- Seasoning - Salt, pepper, and oregano add flavor to your soup. Oregano can be substituted with dried basil or an Italian seasoning blend if desired.
- Granulated sugar - Just enough granulated sugar is added to offset the acidity of the tomatoes in the recipe.
How to make tomato zucchini soup
- Sauté onions in a stock pot.
- Add remaining soup ingredients and stir to combine.
- Bring to a simmer, cover, and reduce heat to low. Simmer until zucchini is fork tender.
- Carefully transfer in batches to a blender (or use an immersion blender) and blend until smooth.
Tips and tricks
Use an immersion blender - If using an immersion blender, carefully blend your soup (off the heat) right in your stock pot.
Use a regular blender - Fill your blender no more than halfway with hot soup. Return the lid to the blender (with center cap removed) and lightly cover with a towel. Starting slowly and gradually picking up speed, blend your soup until smooth. Pour into serving bowls or another stock pot. Repeat until all soup is blended.
Reheat as needed - Your blended soup may need to be reheated slightly before serving.
Storage
Soup will keep for 3-4 days in the refrigerator in a tightly sealed container and reheats well in the microwave or on the stovetop.
Soup can also be frozen for 2-3 months in a tightly sealed container (allow to cool completely before storing in the freezer).
