Picking the best tomatoes for tomato soup
Since the tomato is the star of the show in this soup it’s important to pick the best tomatoes from the start. For a rich and flavorful tomato soup, you will want to select tomatoes that are sweeter and less acidic. Some of the best fresh tomatoes to select include:
- Plum (also labeled Roma)
- San Marzano
How to make Tomato Basil Soup
- Butter– Adds flavor to the base of the soup, swap with olive oil for a vegan soup.
- Cashews– Helps make the soup thick and creamy without adding flour or cream.
- Peppercorns– For a little spice.
- Onions and garlic– Provide aromatics to the base of the soup.
- Tomatoes– Fresh such as plum (Roma) or San Marzano work best.
- Water- To help thin out the soup as needed.
- Spices– A blend of oregnao, salt, sugar, and ground black pepper give the soup some added flavor.
- Basil– Adds a slightly sweet, savory, and almost peppery taste to the soup.
Step by Step Instructions
- Set the Instnat Pot to ‘Sauté’ and adjust the setting to ‘Normal’. When the display reads ‘Hot’, add butter or oil.
- Add cashews, onions, black peppercorns, and garlic. Sauté until the onions are soft and translucent.
- Stir in the chopped tomatoes and mix well.
- Next, pour in the water and salt. Stir to combine.
- Cover the lid and move the vent to “sealing”. Pressure cook on high for 10 minutes. When the cooking cycle is complete do a quick release by moving the steam valve to “venting”.
- Open the lid and add basil leaves. Use an immersion blender to puree the soup. If you use a traditional blender, wait at least 10-15 minutes for the soup to cool down.
- Do a taste test and add salt and pepper if needed. If the soup is too tart, you can add a teaspoon of sugar (or more) to neutralize the sourness.
- Serve immediately.
- Butter– Swap out the butter for olive oil to make this a vegan recipe.
- Water– You can also replace water with a light broth such as chicken or vegetable broth to add a little flavor.
Storing tomato basil soup
- Refrigerate– Keep your tomato basil soup in the refrigerator in an air-tight container for 4-5 days.
- Freeze– Store in the freezer, in a freezer-safe container for up to one month.
- Thawing– Move the soup from the freezer to the refrigerator to thaw overnight before heating and serving.

Frequently asked questions
