Easy Three-Ingredient Tomato Soup Recipe

You wouldn’t think that three ingredients — butter, onion, and tomato — can come together to make such a velvety and delicious tomato soup, but let me tell you. They can. Jump to the Tomato Soup Recipe or watch our quick recipe video showing how to make it.

This tomato soup is inspired by one of the most famous recipes out there — Marcella Hazan’s Tomato Sauce. Butter, tomatoes and onion are simmered until slightly thickened. Out comes the onion and the sauce is ready to be spooned over pasta. It’s genius and absolutely delicious. We use the same three ingredients in this tomato soup, but add a little water and blend everything together just before serving.

How to Make Our 3-Ingredient Tomato Soup Recipe

This soup is quick, easy and insanely delicious. Here’s how to make it.

Grab a Dutch oven or pot, place it over medium heat and melt the butter. Add half an onion that’s been cut into large wedges and a large can of tomatoes.

This soup is excellent with canned tomatoes — We usually go for whole peeled tomatoes or crushed tomatoes. By the way, we love San Marzano Tomatoes and are always pleased with tomatoes from Muir Glen. Neither are watery and both taste great.

Bring everything to a low simmer, add some salt and leave it alone for about 40 minutes. See how creamy it gets? That’s thanks to the butter.

Blend the soup — we find an immersion blender is useful, but a blender works, too. Adjust the soup for seasoning then grab a bowl…and maybe a grilled cheese sandwich ?

Easy Three-Ingredient Tomato Soup Recipe

  • PREP
  • COOK

You only need three ingredients to make this velvety, rich tomato soup recipe. This, friends, is your new favorite weeknight meal.

Makes 2 generous servings

You Will Need

4 tablespoons unsalted butter

1/2 large onion, cut into large wedges

1 (28-ounce) can tomatoes, we prefer to use whole peeled or crushed

1 1/2 cups water or low-sodium chicken stock

1 teaspoon kosher salt, or more to taste


    Melt butter over medium heat in a Dutch oven or large saucepan. Add onion wedges, water, can of tomatoes with their juices, and the salt. Bring to a simmer. Cook, uncovered, for about 40 minutes. Stir occasionally and add additional salt as needed.

    Blend the soup — it doesn’t need to be ultra-smooth, some texture is a nice touch. An immersion blender makes quick work of this or use a blender. If you use a regular blender, it is best to blend in batches and not fill the blender as much as you usually would since the soup is so hot. We like to remove the center insert of the lid and cover it with a kitchen towel while blending — this helps some of the steam release and prevents the lid from popping off (which can be a big, hot mess).

    Super delightful! Pun intended.. this is the best homade tomato soup that I have ever had, at my age (old) I have a lot! Add to its simplicity and the reason for its winning nature, no flavore competing and muddying the pot, becomes clear. Simply delicious is pure decision. Thanks to you for this final and only recipe in my tomato soup ‘collection’.

  • Tracy October 8, 2017, 4:05 pm

    YUMMY! I never comment, but this is worthy of a comment! DELISH! I made it today for the first time. I followed the recipe as stated but instead of 1.5 cups of water, I added 1 cup of water with 2 tsp of vegetable broth concentrate and 1/2 cup of milk – wow! I will forever make this soup and I cannot thank you enough for posting this easy, but delicious tomato soup recipe!!!

  • Vinbar October 5, 2017, 12:06 pm

    Saw this recipe and thought I have leftovers
    from pasta sauce & small amount of pasta so I used this basic recipe: put sauce in pot added onion powder, cut up pasta, shredded basil, and some roasted garlic, enough water to make it a soup and keep the flavor…. so easy so good and had it all on hand!!!

    HOLY MOLY!! BE STILL, MY HEART!! Specifically wanted to leave a comment to let others know how amazing this soup is. Until today, I had never made homemade tomato soup…. but I absolutely LOVE tomato soup and was sick of canned soups with all that added sugar. Upon searching the internet, I stumbled upon this lovely easy-peasy recipe and decided to give it a go. The fact that the recipe had zero added sugar was the selling point for me. I also liked the fact that there was no heavy cream, either. This recipe did not disappoint. It really does taste just as good as Panera’s. I am so happy that this recipe found me. I might be heading back to the grocery store tomorrow to buy more ingredients to make more of this! Thank you so much for sharing this incredibly simple and super tasty tomato soup recipe!!!! <3 <3 I am in love!

  • Margarita September 29, 2017, 8:36 pm

    I had to add basil, garlic, a pinch of sugar and milk in order for this soup to acquire the right taste. Otherwise, it tasted like tomato sauce.
    It was delicious! The idea is great, but it certainly lacks flavor.

  • Kailey September 23, 2017, 7:16 pm

    This was a solid recipe! I added some herbs and a tablespoon of cream, but I had everything on hand already, and loved the taste! Thank you for posting. This is a versatile recipe that I will definitely use again.

    A friend told me about how delicious her crockpot, home grown tomato soup was. I never thought to make my own, but I didn’t want to wait 8 hrs or deal with the skins. Your recipe appealed to me because of the simplicity and quick cooking time. My son who never holds back on “constructive” criticism, was WOWED by this soup. He said it tastes a lot like Panera Bread tomato soup, which is his favorite. Had to stop canned soup long ago. Thanks for sharing!

    I have a million tomatoes from the garden…if I use them should,I peel them?

    • Joanne November 7, 2017, 3:52 pm

      Hi Sally, I’d peel them. Although, if you have a high powered blender — like Blendtec or Vitamix, you can probably blend it smooth enough to not even notice the skins.

    Alright, so I’m in the middle of hurricane Harvey, no stores are open, and my roommate is craving tomato soup right? We have nothing in our kitchen so I’m looking up recipes and I find this, which, looks really easy and I have all the ingredients. Guys. I don’t like tomato soup, but this was one of the best soups I’ve ever had. Absolutely amazing and creamy and I about died. Speaking as a broke college student this is such a good recipe to make on a budget and I can make a whole bunch and freeze it for later!!!!! Thank u so much for this godsend!!!

  • Diahann August 26, 2017, 3:09 am

    I’m making the tomato soup recipe with fresh tomatoes.Thank you I’m sure it will be amazing. I question why recipes call for low sodium stock when you add so much salt in the recipe ingredients?

    • Joanne November 7, 2017, 3:53 pm

      We prefer to use low sodium tock in our kitchen so we can control the amount of salt added to the recipe, especially since it varies from brand to brand.
