Ingredient notes and substitutions
- Vegetable broth: Using low sodium broth helps to keep the soup from being too salty. Feel free to use chicken broth if you prefer.
- Carrot: The carrot helps to provide some sweetness and also helps to reduce some of the acidity in the soup.
- Tomatoes: San Marzano tomatoes have less acidity than other types of whole canned tomatoes. If you can't find San Marzano tomatoes, you can use a different type of whole tomato. You may just find that you need to add additional carrot or sugar to help balance out the acidity.
- Sugar: The sugar helps to balance out the soup. If you would like to omit the sugar, you can.
How to make Instant Pot tomato soup
Step 1: Add all ingredients to the Instant Pot inner pot in the order given. Do not stir.
Step 2: Close and lock the lid. Be sure that the pressure release valve is set to sealing.
Step 3: Press manual high pressure and adjust the time to 15 minutes.
Step 4: Once the cooking time has ended, let the pressure naturally release for 10 minutes.
Step 5: Carefully turn the pressure release valve to venting to release any remaining pressure.
Step 6: Carefully puree the soup with an immersion blender until smooth.
Step 7: Adjust seasonings to taste.
Step 8: Serve soup with fresh chopped basil and croutons, if desired.
- Sautéing vegetables: If you'd like to sauté the vegetables before cooking, you can. Simply add the olive oil to the hot Instant Pot inner pot. Add the onion and carrot, and sauté, stirring regularly, for 3-4 minutes. Add the garlic, and sauté for 30 seconds, stirring the entire time. Deglaze with ¼ cup vegetable broth and scrape up any browned bits from the bottom of the pot. Add the ingredients, and do not stir. Continue with the recipe as-written.
- Chunky soup: If you'd like chunkier soup, crush the tomatoes against the side of the pot before cooking and don't puree after cooking.
- Extra flavor: For even more flavor, swirl in 1-2 tablespoons of prepared basil pesto before serving.
- Serving: Serve the soup topped with croutons, with crusty bread, or with grilled cheese soup.
Store any leftover tomato soup in an airtight container in the refrigerator. The soup will keep for up to 4 days when properly stored in the fridge.
