Why This Recipe Works

One-Pot Wonder: Everything—from blooming the aromatics to the final swirl of cream—happens inside the Instant Pot, so you’ll wash only the insert and your blender jar.
Canned-Star Ingredients: Fire-roasted tomatoes and creamy cannellini beans deliver slow-cooked flavor with pantry convenience.
Silky Without Heavy Cream: A modest splash of half-and-half plus a handful of cashews blended in create luxurious body for a fraction of the saturated fat.
Pressure-Infused Basil: Cooking under pressure traps the volatile oils from fresh basil, amplifying perfume you’d otherwise lose in stovetop simmering.
Vegan-Optional: Swap coconut milk for the dairy and you’ve got a plant-powered bowl that still feels indulgent.
Freezer-Friendly: Make a double batch; leftovers reheat like a dream for up to three months.
Kid-Approved: My bean-skeptic nine-year-old slurps this because the beans vanish into the puree—no “weird textures,” only creamy tomato goodness.

Ingredients You'll Need

Before we dive into the method, let’s talk ingredients—because the right tomato and the right bean make or break this soup.

Fire-Roasted Diced Tomatoes: Look for a brand that lists “tomato juice” as the only additional ingredient. The charred edges add smoky depth you can’t coax from plain diced tomatoes. If you can only find whole fire-roasted, dump them on a cutting board and give a quick chop.

Cannellini Beans: These Italian white kidney beans are creamier than Great Northerns. If you cook beans from scratch, 1½ cups cooked equals one 15-oz can. Rinse canned beans to remove 40 % of the sodium; nobody wants a salty soup.

Tomato Paste in a Tube: You’ll use 2 Tbsp here and won’t waste a 6-oz can. Double-concentrated paste is worth the splurge—it’s glossy, jammy, and lends umami sweetness.

Yellow Onion & Carrot: My soffritto starter. Dice small so they melt into the broth. A carrot brings subtle sweetness that balances tomato acidity.

Fresh Garlic: Two fat cloves, smashed and minced. Jarred garlic tastes metallic under pressure; don’t do it.

Extra-Virgin Olive Oil: Use the good stuff for sautéing; flavor compounds survive pressure cooking and you’ll taste them in the finish.

Vegetable Broth: Low-sodium lets you control seasoning. Chicken broth is fine for omnivores, but veggie keeps it universally friendly.

Raw Cashews: Just ¼ cup lends dairy-free silkiness. If you’re nut-free, substitute ½ cup diced potato for similar body.

Fresh Basil: A full cup of leaves, gently packed. Winter basil can be sulky—if yours is pale, perk it up in a mug of tepid water for 10 minutes before chopping.

Half-and-Half: For vegan, swap full-fat coconut milk; the faint coconut marries surprisingly well with tomato. Light coconut milk works too, but soup will be thinner.

Balsamic Vinegar: A teaspoon at the end wakes up everything, like lipstick on a familiar face.

How to Make Instant Pot Creamy Tomato and White Bean Soup

Warm the insert

Remove the Instant Pot lid and press Sauté > Normal. Wait until the display reads “Hot,” then swirl in 2 Tbsp olive oil. Tilting the pot coats the surface and prevents the onion from sticking.

Build the aromatics

Add diced onion and carrot plus ½ tsp kosher salt. Stir every 30 seconds for 3 minutes until edges turn translucent. Stir in tomato paste; cook 1 minute until brick red. Add minced garlic; cook 30 seconds until fragrant but not browned.

Deglaze

Pour ¼ cup of the vegetable broth into the hot pot. Scrape the bottom with a flat wooden spoon to lift any caramelized bits (fond). This step prevents the dreaded “Burn” notice and sneaks extra flavor into the broth.

Load the stars

Add remaining broth, fire-roasted tomatoes (with juice), cannellini beans, cashews, and 1 cup loosely packed basil leaves. Do not stir after this point; layering keeps tomatoes off the bottom and reduces burn risk.

Pressure cook

Lock the lid, set the valve to Sealing. Select Manual/Pressure Cook > High Pressure > 10 minutes. The pot will take 8–10 minutes to reach pressure; total elapsed time is ~20 minutes.

Natural then quick release

When the timer beeps, wait 5 minutes (natural release), then carefully turn the valve to Venting to release remaining steam. Remove the lid away from your face to avoid condensation drips.

Blend until silk-smooth

Use an immersion blender directly in the pot, tilting it slightly for deeper vortex. Alternatively, transfer in two batches to a countertop blender; remove the center cap and cover with a folded towel to vent steam. Blend 45 seconds until no flecks of basil remain.

Finish with cream & acidity

Return the blended soup to the pot on Sauté > Low. Stir in half-and-half and balsamic vinegar. Heat 2 minutes until steaming; do not boil or cream may curdle. Taste and adjust salt (½ tsp more is typical) and freshly ground black pepper.

Serve & garnish

Ladle into warm bowls. Top with a drizzle of olive oil, cracked pepper, and a chiffonade of fresh basil. Crusty sourdough or grilled-cheese soldiers are non-negotiable.

Expert Tips

Choose the right tomato brand

Muir Glen and Cento fire-roasted tomatoes consistently score high for sweet-smoky flavor. Avoid versions packed in puree; they muddy the color.

Soak cashews in a flash

Forgot to soak? Cover with boiling water and microwave 2 minutes, then let stand 5. They’ll soften enough for silky blending.

Thickness lever

Too thick? Thin with broth or milk. Too thin? Simmer on Sauté 5 minutes, stirring; the cashews will continue to thicken as they cool.

Avoid foam overflow

If doubling the recipe, increase pressure time to 12 minutes and be sure the pot is no more than ⅔ full to prevent bean foam from clogging the valve.

Immersion blender safety

Keep the blade submerged; pulse first to break surface tension, then blend continuously to avoid hot splatter burns.

Brighten last-minute

A whisper of lemon zest or an extra drop of balsamic just before serving re-elevates flavors that dull as soup sits.

Variations to Try

Smoky Paprika & Chipotle
Add ½ tsp smoked paprika with the tomato paste and a minced chipotle in adobo for a Spanish riff. Finish with manchego crostini.
Spinach-Basil Swap
Out of basil? Substitute 2 cups baby spinach plus 1 tsp dried oregano. The color will be deeper green, still lovely.
Protein Boost
Stir in shredded rotisserie chicken after blending for a Tuscan-chicken version. Add 1 cup diced zucchini before pressure cooking for veg-plus texture.
Gluten-Free Croutons
Cube stale gluten-free bread, toss with olive oil, garlic powder, and bake 10 minutes at 400 °F while the pot pressurizes.

Storage Tips

Refrigerate

Cool completely, transfer to airtight glass jars, and refrigerate up to 5 days. Reheat gently; do not boil or cream may separate.

Freeze

Ladle into freezer-safe quart bags, squeeze out air, lay flat to freeze. Keeps 3 months. Thaw overnight in fridge, then warm slowly.

Make-Ahead Lunch Jars

Portion 1½ cups into 16-oz jars. Add a cube of frozen basil pesto on top. By noon the pesto has melted into a flavor bomb.

Frequently Asked Questions

Yes, but cook them first. Un-soaked cannellini take 35–40 minutes under pressure plus a 10-minute natural release. Use ¾ cup dried beans to equal one 15-oz can.

Stir in ½ tsp sugar or a pinch of baking soda (alkaline) to neutralize acid. Another swirl of cream also mellows sharpness.

Absolutely. Keep max-fill line in mind and increase pressure time to 12 minutes. Use a 32-oz carton of broth plus 2 cups water to stay under the line.

Yes, all listed ingredients are naturally gluten-free. If adding croutons or broth, verify labels for hidden wheat.

Sauté aromatics on the stove, then transfer everything except cream to a slow cooker. Cook 4 hours on LOW. Blend, then stir in cream and warm 10 minutes more.

Cancel cooking, quick-release steam, open and scrape bottom thoroughly. Add ½ cup extra broth, ensure tomato layer is off the base, then reseal and restart.
