Secret Ingredient Tomato Soup

$2.62 recipe / $0.66 serving

I don’t know if I’ve told you, but I’m a little bit of a tomato soup fanatic. I’ve made several tomato soup recipes for Budget Bytes over the past ten years, but this week I tried something a little different. This Secret Ingredient tomato soup has not one, but two secret ingredients that make it ultra rich, without using any dairy, or animal products at all, in fact. This super luscious, warm and comforting, thick and delicious Secret Ingredient Tomato Soup is 100% vegan.

What are the Secret Ingredients??

After the success of my Easy Rosemary Garlic White Bean Soup, which uses puréed cannellini beans to thicken and make the soup extra creamy, I wondered how puréed beans would work in other soups. The cannellini beans did a great job giving this tomato soup body and richness, without having to use butter or cream.

The second secret ingredient is nutritional yeast. If you’ve never had nutritional yeast before, it’s a flakey dehydrated powder that has a slightly nutty or cheesy flavor (it also happens to be high in B vitamins!). The slight cheesy flavor of the nutritional yeast was the final magic touch that took the flavor of this soup over the top. The flavor is super subtle, but rounds out the base notes to keep the flavor deep and rich.

Can I Use a Different Type of Bean?

While I haven’t tried other varieties, I will say that cannellini are particularly smooth and creamy. I wouldn’t expect other beans to give quite as good results.

Can I Freeze This Tomato Soup?

Yes, this tomato soup should freeze beautifully. Just as a reminder, make sure to cool the soup completely in the refrigerator before transferring to the freezer. It’s always a good idea to divide the soup into smaller portions for faster cooling.

The tomato paste and oil mixture looks weird, and won’t really mix together, but don’t worry, you’re doing it right.
