I love having a bowl of soup on a cold winter night. I even like it in the springtime, because it’s so quick and easy to make.

Yes, I love serving the best vegan soups all year long!

This vegan tomato soup is a favorite, go-to recipe on busy nights because it’s made with only a few ingredients and is full of flavor. It’s like comfort food in a bowl!

Ingredients are laid out on a table. The labels next to them read, chopped onions, vegan butter, diced tomatoes, garlic, brown sugar, and vegetable broth.

Key Ingredients

  • Lemon — We’ll use both the zest and the juice of the lemon.
  • Oats — I used rolled oats for this recipe, but you can substitute instant oats.
  • Chia — We’ll add some ground chia seeds to create a thicker texture. You can use whole chia seeds; I just prefer ground because it creates a smoother finished texture.
  • Syrup — I used maple syrup, but you can substitute agave nectar.
  • Milk — We’ll use almond milk for the best overnight oats! Substitute your favorite plant-based milk.
  • Yogurt — I love adding some plant-based yogurt (plain, unsweetened) for an even more tangy flavor.
  • Protein Powder — I add some vanilla protein powder for increased flavor and nutrients. If your protein powder is not sweetened, you may want to add an extra teaspoon or two of sweetener.
  • Cornstarch — We’ll use cornstarch to thicken the lemon curd topping.
  • Turmeric — A pinch of turmeric makes that lemon curd sunny yellow.
  • Vegan butter — Feel free to use tub margarine, storebought or homemade vegan butter, or substitute olive oil.
  • Onion — You’ll need 1 medium yellow or white onion.
  • Garlic — You can use either 1 or 2 cloves of garlic.
  • Tomatoes — This recipe uses two 15-ounce cans of tomatoes. You can use whole, peeled, or crushed tomatoes. Feel free to substitute one 20 ounce-can.
  • Vegetable broth — Use a high-quality vegetable broth like Better than Boulillion Vegetarian Base or No Chicken Base.

Marly’s Tips

Make it creamy! You can add a bit of creaminess to most vegan soup recipes by adding cooked beans or even a cooked potato. Adding even 1/2 cup of cooked white beans (such as cannellini or chickpeas) to the blender will do the trick.

Why This Recipe is a Winner

  • Canned tomatoes are available year-round, making this recipe easy and accessible
  • Adding a bit of brown sugar cuts the acidity
  • You can leave some texture or press it through a fine mesh strainer for a velvetty smooth soup.

Frequently-Asked Questions

Is tomato soup vegan?

Some tomato soups may be vegan, depending on whether cream has been added or if a vegetable broth was used (instead of a meat-based broth). However, it’s very easy to make your own tomato soup vegan at home.

Tomato soup is naturally gluten-free because the primary ingredients are tomatoes, onions, and broth. If you are highly sensitive to gluten, be sure to choose ingredients that are certified gluten-free.

Secure the lid on the blender and top with a kitchen towel. Blend on low speed for a few seconds, then slowly increase speed to create a relatively smooth soup, leaving some texture. Transfer to a bowl, then repeat with remaining ingredients from the pan.

Notes

Using Fresh Tomatoes

If you want to use fresh tomatoes, substitute around 10 medium tomatoes (approximately 2 pounds), and cook until the tomatoes are tender. 

Fat Substitutes

Use vegan butter, refined coconut oil, or olive oil.
For a no-oil version, simply cook the onions with a little white wine or vegetable broth.

Adding Herbs

You can add 5 to 10 leaves of fresh basil right before blending for even more added flavor. Substitute 1 teaspoon dried basil and/or oregano.

Making it Creamy

Adding beans makes this soup creamy. You can use either cannellini beans or chickpeas to achieve this effect. Another option is adding a cup of vegan creamer (make sure it’s plain (not flavored) and preferably unsweetened (including no added sweeteners such as stevia or monk fruit).
