Three Ingredient Tomato Soup

This might just be the simplest tomato soup out there! The flavors are so rich, though, your guests won’t believe it’s made with just sauteed onions, bell pepper and tomatoes. We made this for Sunday Brunch Cooking + Eating and one of my guests asked, “And you added some garlic, right?” Nope. “And some basil?” Nope.

Just tomatoes, onions and bell pepper. But you will need LOTS of tomatoes.

When my mom taught me this recipe I couldn’t believe it. This was back in my college years and my only experiences with tomato soups were those pizza-sauce-like, canned-tomato ones served at fast food restaurants. This one is creamy and real and tasted incredibly gourmet to my fast-food palate.

Three Ingredient Tomato Soup

Prep Time: 5 minutes

Cook Time: 25 minutes

4-6 servings


  • 7-9 ripe tomatoes, roughly chopped*
  • 1 medium onion, chopped
  • 1/2 red bell pepper, chopped
  • olive oil
  • sea salt, veggie bouillon or broth


  1. In a medium pot, pour enough oil to just cover the surface. Sauté onion and bell pepper over medium-high heat for about 7 minutes, stirring occasionally.
  2. Add tomatoes and their juices. Bring to a boil then cover and reduce heat to a simmer.
  3. When tomatoes have sweated out and are "mushy," transfer to a blender and add home-made broth and/or salt to taste or 1 and 1/2 veggie bouillon in a pinch.
  4. Blend well, return to pot if it needs to be heated and serve.


* I used 7 tomatoes on the vine, if you don't have enough tomatoes you can add tomato paste when blending

* When we made it for Brunch we added 1 1/2 Rapunzel organic vegan bouillon. We did not add water since we wanted a thick, creamy soup, but you can dilute it if you'd like!

Hi! Thanks for reading! I’m a certified nutritionist exploring the local & sustainable foods scenes in The Woodlands and Houston! Keep in touch and follow me! As of 2017 my sister and I just opened an outdoor dessert café – check it out! I couldn’t be more excited!


  1. this is the best! I made it and it was super quick and my dad said it was the best tomato soup he’s ever tasted. It’s just everything! :) thank you! x

    • Caitlin, thank you for sharing! I’m so glad you guys liked it. Sharing food with people you love is the best – wish my dad would let me feed him more often (and liked it)! Enjoy!

  2. Those tomatoes look beautiful… Love this recipe! I got my husband to start loving tomato soup, and now he wants it all the time! I’ve never tried it with bell pepper… I think that is a brilliant idea!! :D Adding this to my future dinners list!

    • Thanks for stopping by! Hope you guys enjoy the bell pepper addition! I prefer to use fresh tomatoes and never canned but if the bell pepper was too much/too strong you can quickly fix it by adding tomato paste (I’ve had to do that several times!)
