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.

Easy Three-Ingredient Tomato Soup Recipe

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

Let’s review.

  • This tomato soup has three ingredients (plus water and salt).
  • Everything is tossed into a pan — no browning, no hovering over a stove.
  • You can use canned tomatoes — and should.
  • Did I mention there are only three ingredients?

This is your new favorite weeknight meal. Promise.

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

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).

    Do I have to use onion, don’t currently have any on hand could I use onion powder or onion salt instead?

    • Joanne November 8, 2016, 2:29 pm

      Onion does add a nice texture when it is blended into the soup, however, you could try using onion powder to make up for the loss of flavor.

  • Barb October 15, 2016, 6:10 am

    Yummy tomato soup but has anyone added basil or other spices?

    • Joanne October 16, 2016, 12:06 pm

      We have added basil ourselves and loved it. Most fresh herbs (or a combination) would be lovely.

  • Julie October 13, 2016, 7:29 pm

    I’m allergic to anything related to the Lily, so no onions or garlic for me! Is there something you can think of that I could substitute the onions for? This soup sounds amazing!

    • Joanne October 14, 2016, 2:06 pm

      Hi Julie, I wonder if fennel would be a good alternative? Or maybe a combo of celery and fennel. The soup will taste different, but I’m talking myself into making a batch of my own as I write this. It sounds tasty!

  • Daphne October 13, 2016, 2:09 pm

    Hi glad I found your easy tomato soup recipe, made it and loved it. Thanks so much!

  • Kay Lumsden October 10, 2016, 3:39 pm

    Just made this soup, it’s absolutely brilliant and my husband loves it….thankyou for sharing the recipe…..

  • Khadijih September 21, 2016, 11:24 pm

    This is a great recipe!So easy and I even used home grown tomatoes and skinned them.I added organic beef broth because I had some and a decent amount of dried basil. My toddler licked the bowl clean(and so did I)! Delicous,thank you for this recipe!

  • Griselda August 29, 2016, 8:36 pm

    Easy and most convenient way to make tomatoe soup. I enjoy the texture and taste!!!

  • Deirbhile August 23, 2016, 11:44 pm

    Dear Tracy,
    I am only 13 and I had to cook dinner. I love tomato soup and thought it would be easy. I spent about an hour scrolling through multiple recipes until I came to this one and thought this is perfect. the whole family loved it and I could make it. It is amazing!!!

  • Heather August 21, 2016, 7:49 pm

    Would stewed tomatoes work? I just caned a bunch and they have a lot of liquid so I’m thinking I wouldn’t have to add water.

    • Joanne August 22, 2016, 1:46 pm

      They would be great. If the soup is too thick at the end, you could add a little water then.

  • Tracy Rowan August 15, 2016, 3:49 pm

    That’s Marcella Hazan’s pasta sauce thinned down. Your inspiration is beyond reproach, but you really ought to credit her.

    • Joanne August 22, 2016, 1:47 pm

      Hi Tracy, we do credit Marcella Hazan (it’s at the top of the article).

  • Judy August 13, 2016, 3:16 pm

    Can I freeze this soup?

    • Joanne August 22, 2016, 1:48 pm

      Yes, definitely.

  • Lily August 8, 2016, 9:17 pm

    Made this tonight. Only had 1 can diced tomatoes and 3 tomatoes from the garden, but used anyway. Also threw in 2 stalks of celery for good measure! So easy & tasty. My new favorite soup!

  • Sheila August 8, 2016, 6:40 pm

    I used chicken broth instead of water….not vegan but so yummy!!

  • Trina August 2, 2016, 5:46 pm

    This is a tasty tomato soup. My husband and love to go to Panera Bread. He gets tomato soup and cesear salad. Now we don’t have to go there. Yay!! P.S. My husband thinks it’s even better than Panera Bread!

  • Elizabeth June 3, 2016, 12:40 pm

    Gloomy, cloudy day. Wanted tomato soup for dinner to go along with grilled romy cheese and ham sandwiches. I will be making this again and again. So easy and perfect for today as I feel like I have been run over by a Mack truck. Even with my deadened taste buds it tastes great. Much better than what comes out of a can. I bet it would be good cold on a hot summer evening. Can I give it 10 stars?

  • Rachel May 5, 2016, 10:43 pm

    I was amazed at how simple this recipe was to make! And so fun! The only catch was that I am very sensitive to lactose and substituted some margarine instead. Sadly, without the butter it turned out fairly sour and not very creamy. Do you have any suggestions for a dairy-free substitute? I love tomato soup, and especially the idea of a simple, 3-ingredient homemade one!

    • Sarah August 28, 2016, 9:57 am

      Try coconut oil for the butter. Yum.

    • Sarah Lewis September 23, 2016, 4:44 pm

      I’ve made another tomato soup with great results that used olive oil and almond milk for the creaminess.

  • Marian April 25, 2016, 2:12 pm

    I was skeptical about this recipe even after rave reviews. I am really picky about tomato soup so I made half the recipe to try it out. This is absolutely the easiest and best tasting tomato soup ever. I highly recommend you try this just the way it is written. Can’t wait to make a full recipe to serve my family. This is also gluten free. Most canned soups have wheat added. Thanks for sharing this recipe!!!

  • Sherri Fox April 5, 2016, 2:48 pm

    OH. EM. GEE. This was simply awesome. Everyone at the table LOVED it. So easy to make, and oh so yummy. THANK YOU for this recipe! Served ours with grilled cheese too 😉

  • Rhea March 31, 2016, 4:28 pm

    I’m a fan after me and my hubby tried it!!! What a brilliant easy recipe to go to. I would rate this more than 5 stars. Lol

  • Garda Cuthbert March 25, 2016, 11:48 am

    I can’t wait to try this soup! It sounds fantastic and easy. Now I am hungry for homemade soup and a grilled cheese sandwich!
    I’m giving the soup a 5 star rating because I’m wagering it is the best there is.

  • Gloria March 24, 2016, 12:16 am

    I’d use vegetable broth or chicken stock and add some herbs. Mostly because i always have a lot of fresh herbs from my garden

  • Swee March 5, 2016, 9:06 pm

    I had some extra cans of diced tomatoes and wondered what we were going to do with them. I had a taste for tomato soup and grilled cheese so I Googled recipes for homemade tomato soup and the link for this recipe came up. I’m sooo glad it did! I made this recipe just as directed (the video presentation was super easy to follow and nicely put together). I added sugar to it as well. The recipe turned out great. All four of my children really enjoyed it and it had a great texture to it. I give this recipe 5 stars. Delicious.

  • Ella January 16, 2016, 6:46 pm

    This recipe is great. I absolutely love this recipe. This is the best tomato soup I’ve ever had!!! 😀

  • Shaina December 21, 2015, 2:30 pm

    Perfect. I love how uncomplicated and straightforward this is.

  • JulieD December 21, 2015, 12:23 pm

    This looks so good! Love how easy it is!

  • Brenda @ a farmgirl's dabbles December 18, 2015, 8:58 am

    How absolutely perfect is this?! Tomato soup is our go-to weeknight supper during the winter. With gooey grilled cheese sandwiches, of course. 😉

  • Joanne @ Fifteen Spatulas December 16, 2015, 3:52 pm

    How funny! I just discovered the Marcella Hazan recipe two days ago. I’m going to try your soup too! I’ve been on a grilled cheese + tomato soup kick lately.

  • Linda Cottrell October 14, 2015, 8:49 pm

    Is the water added at the same time as the onions and tomatos?
    Are the tomatoes used un-drained?
    Thank you

    • Joanne October 15, 2015, 11:53 am

      Hi Linda, Yes, we add the water along with the tomatoes and the tomatoes are undrained.

  • Arc October 7, 2015, 7:19 pm

    This is almost identical to my own tomato soup recipe – the main differences being that I also add copious amounts of garlic (whole; no need to chop), a pinch of sugar and some fresh basil leaves on the top. I have never used butter but I Shall try it next time, it sounds delicious – I don’t know why it didn’t occur to me before.

    Tomato soup is also fantastic with crispy bits of home cured bacon, if you fancy getting a bit more complicated.

    5* from me!

  • Danielle @ So Munch Love October 7, 2015, 4:22 pm

    I’m starting to think I have been over complicating tomato soup all this time. This looks delish! I’ve got to try these on a bunch of tomatoes I have sitting in the fridge. Thanks for sharing!
