👩🏽‍⚕️ Dietitian's Note

This vegan tomato soup turns the classic into a more balanced, satisfying meal. Butter beans provide plant-based protein and fiber, while also contributing minerals including potassium, magnesium, iron, and zinc. Blending them into the soup creates a naturally creamy texture without relying on heavy cream or cashews, bringing each serving to 15 grams of protein and 15 grams of fiber.

Tomatoes are rich in lycopene, an antioxidant whose bioavailability increases with cooking. Because lycopene is fat-soluble, serving the soup with a source of healthy fat can help increase their absorption, particularly if you prepare the soup oil-free.

Why You'll Love This Recipe:

This Vegan Tomato Basil Soup is not only cozy and delicious. It's also:

Creamy without cream: Butter beans create a silky texture without dairy, coconut milk, or cashews.
High in protein and fiber: Each serving has 15 grams of protein and 15 grams of fiber.
Mostly hands-off: The oven does most of the work-roast, blend, and serve.
Meal-prep friendly: Refrigerate for up to 5 days or freeze for up to 3 months.

👩🏼‍🌾 Ingredients

Below, I share ingredient notes from both a nutrition expert's and trained chef's perspective.

Vine tomatoes, olive oil, vegetable broth, basil, chopped onion, butter beans, nutritional yeast, maple syrup, and garlic on a marble board.

Butter beans have a mild, buttery flavor and blend into the soup for an exceptionally creamy, velvety texture without overpowering the roasted tomatoes and basil.
Vine-ripened tomatoes have a naturally sweet, full tomato flavor. Roasting concentrates their sweetness and savory umami while adding caramelized depth for a richer tomato basil soup.
Fresh basil brings a sweet, peppery, and aromatic freshness that balances the richness of the roasted tomatoes and garlic. Add extra just before serving for an even brighter basil flavor.
Roasted garlic becomes sweet, mellow, nutty, and almost caramelized in the oven. Using a whole head adds deep savory flavor without the sharp bite of raw garlic.
Nutritional yeast adds a savory, slightly nutty, Parmesan-like flavor that enhances the soup's umami. It is optional but adds another layer of richness.
Olive oil is optional.

🍅 Substitutions

This recipe is versatile and easy to adapt. Below are some simple ingredient substitutions.

Butter beans: Any variety of white beans will work (Great Northern, navy, or cannellini beans).
Vine tomatoes: The vine tomatoes can be replaced with an equal weight of cherry, grape, or regular tomatoes but the soup will be slightly less sweet and more acidic tasting.
Olive oil: Use balsamic vinegar instead for oil-free
Fresh basil: Instead of fresh basil, use 1 tablespoon plus 1 teaspoon of dried basil.
Nutritional yeast: Omit as needed.
Tomato paste: Omit as needed.
Spicy: Add crushed red pepper while roasting for some heat.

📝 How to Make Vegan Tomato Basil Soup

The complete recipe with exact amounts is below. These additional tips will help you get the best results.

Eight vine tomatoes, chopped onion, and a head of garlic in a white baking dish with olive oil.

Place the tomatoes, onion, and garlic in a single layer for roasting so that they have space to brown. Overcrowding the baking dish will induce steaming. Browning the veggies adds much more flavor to the soup.

Roasted vine tomatoes, chopped onion, and a head of garlic in a white baking dish with olive oil.

Roast for 35 minutes or until the tomatoes have softened and the onion is golden brown.

Roasted vine tomatoes, onion, garlic, as well as butter beans, nutritional yeast, and basil leaves in a large white saucepan.

Use a nonreactive saucepan made from a material that will not react with acidic ingredients to warm the soup. Otherwise, the acid in the tomatoes will mix with the metal and result in an unpleasant metallic taste. Stainless steel and enamel cookware are the best options. (Uncoated aluminum and iron are both reactive.)

Optional for serving: Add a splash of unsweetened oat milk for more creaminess, or my quick Nondairy Cream or Tofu Cream for a an additional protein and flavor boost. This is especially beneficial if you omit the oil, as consuming tomatoes with a source of dietary fat can increase the absorption of lycopene and other antioxidants.

✔️ Storage & Meal Prep Tips

These simple tips will help this vegan tomato soup stay fresh and delicious:

Storage: Allow the soup to cool completely, then transfer it to an airtight container and refrigerate for up to 5 days. If the soup thickens in the refrigerator, add a splash of vegetable broth or water until it reaches your desired consistency.
Freezing: This tomato basil soup freezes well for up to 3 months, making it ideal for meal prep. Freeze in individual portions for quick lunches or dinners, leaving a little room at the top of the container for expansion. Thaw overnight in the refrigerator before reheating.
Meal Prep: Make a batch ahead and portion it into individual containers for easy meals throughout the week. Keep any toppings or garnishes separate and add them after reheating for the best texture and flavor.

🙋🏽‍♀️ Recipe FAQs

Can I use a food processor to blend the tomato soup?

Yes! A blender, food processor or immersion blender will work.

Why do you put baking soda into tomato soup?

You can use baking soda instead of a sweetener to neutralize the acidity of the soup. When you add baking soda to tomato soup, it neutralizes the acid in the tomatoes. Not only will this make the tomatoes taste less acidic, but it also means that you can now add milk to your soup without risking curdling it.

Why should you not boil tomato soup?

Boiling reduces the flavor in the soup. Instead, simmer your Vegan Tomato Soup until warmed through.

What are some tips for making vegan tomato soup?

For the richest flavor, roast the tomatoes, onion, and garlic until lightly browned and caramelized rather than simply cooking them until soft. Use ripe, flavorful tomatoes, and blend in white beans for a creamy texture without dairy or cashews. Fresh basil adds the brightest flavor, so add it when blending rather than roasting it. If the soup tastes too acidic, a small amount of maple syrup can balance the tomatoes without making the soup noticeably sweet.
