Why You’ll Love This Recipe

This soup is a genuine time-saver. Thanks to the Instant Pot, it goes from start to finish in under 30 minutes, yet the combination of ripe tomatoes, fresh basil, and a touch of cream tastes like it simmered all day. The flavor is bright and layered, striking that perfect balance between sweet, savory, and herbaceous.

It is also refreshingly simple and flexible. You likely have most of these pantry staples on hand already, and with just a couple of easy swaps you can make the soup vegan or gluten-free. That combination of convenience and adaptability makes it the kind of recipe you will return to all season long.

Ingredients

The backbone of this soup is 1 (28 oz) can of San Marzano tomatoes, prized for their rich, sweet flavor, though fresh ripe tomatoes work wonderfully too. Building the flavor base are 1 medium diced onion and 3 cloves of minced garlic, sauteed in 1 tablespoon of olive oil. Swap the onion for a shallot if you prefer a slightly sweeter note.

To bring it all together you will use 2 cups of vegetable stock, where a good-quality stock makes a real difference, plus 1/4 cup of fresh chopped basil for that vibrant herbaceous kick. A 1/4 cup of cream adds richness, though coconut milk or cashew cream keeps it vegan, and 1 tablespoon of balsamic vinegar deepens the natural sweetness of the tomatoes. Finish with salt, pepper, and an optional pinch of red pepper flakes for gentle heat.

Cozy Instant Pot Tomato Basil Soup ingredients

Step-by-Step Instructions

Start by building flavor at the base. Using the Sauté setting on your Instant Pot, heat a drizzle of olive oil, then add the diced onion and minced garlic. Stir until softened and fragrant, about 3 minutes, which coaxes out their natural sweetness before the tomatoes go in.

Next, add the tomatoes and stock. Pour in the can of San Marzano tomatoes, or your fresh tomatoes if using, along with the 2 cups of vegetable stock. Stir in salt, pepper, and the red pepper flakes if you want a little warmth. Give everything a good stir to combine.

Now cook it under pressure. Place the lid on the Instant Pot, set the valve to sealing, and cook on Manual High Pressure for 10 minutes. Once the cycle is complete, carefully perform a quick release of the pressure before opening the lid, standing back from the steam.

Time to blend it to perfection. Use an immersion blender directly in the pot to puree the soup until it is silky smooth. If you do not have one, carefully transfer the soup to a countertop blender in batches, making sure the steam can vent so nothing spills.

Finish with basil and cream. Stir in the freshly chopped basil, a splash of balsamic vinegar, and the cream or coconut milk. Taste and adjust the seasoning as needed, then ladle it into bowls. In under 30 minutes you have a warm, velvety soup ready to be enjoyed.

Tips for the Best Tomato Basil Soup

Like many soups, this one only gets better with a little rest. If you can, make it ahead, since the flavor deepens beautifully after chilling overnight in the fridge. When you do blend, a good-quality balsamic vinegar with subtle sweetness really elevates the finished bowl, so it is worth reaching for a nicer bottle.

If you do not own an immersion blender, a standard countertop blender works fine as long as you vent the steam to avoid spills and blend in batches. This soup practically begs to be paired with something crisp and cheesy, so serve it with a classic caprese grilled cheese with pesto for the ultimate cozy combo, or explore another comfort favorite like our cozy French onion soup.

For variations, add extra red pepper flakes or a pinch of cayenne for a spicy version, or swap the cream for coconut milk or homemade cashew cream to keep it dairy-free. A grilled cheese sandwich, crusty sourdough, or a simple side salad all turn this into a satisfying, balanced meal.

Frequently Asked Questions

Can I freeze this soup?
Absolutely. Let it cool completely, store it in an airtight container, and freeze for up to 3 months. Thaw it overnight in the fridge before reheating gently on the stove.

How do I reheat leftovers?
Reheat gently on the stovetop over medium-low heat, stirring occasionally, or microwave in 30-second increments until warmed through. Low and slow keeps the texture smooth and creamy.

Can I make this soup vegan?
Yes. Simply substitute the cream with coconut milk or your favorite dairy-free alternative. The rest of the ingredients are naturally plant-based, so the soup stays rich and comforting.

Can I use fresh tomatoes instead of canned?
You can. Use ripe, in-season tomatoes for the best flavor and swap them in at the same stage as the canned tomatoes. The pressure cooking will soften them beautifully before you blend.

Why add balsamic vinegar?
Just a splash of balsamic enhances the natural sweetness of the tomatoes and adds a subtle complexity that rounds out the whole bowl. Stir it in at the end so its flavor stays bright.

There you have it, a soup so simple yet so satisfying that you will want to make it again and again. For more ways to build a cozy, balanced table, browse these healthy eating ideas, and tag @thekitchensaid on Instagram so I can see your creations.
