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.

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).

    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!!!

  • Seid August 14, 2017, 11:15 am

    This is great! I can’t cook to save my life but this recipe was really easy to follow with great results.

    • Julia Karpinsky August 16, 2017, 1:51 pm

      amazing is all i have to say

  • Corey August 10, 2017, 8:50 pm

    It was a damn rainy day and was in he mood for some tomato soup. Man 40 minutes later and voila tomato soup and I didn’t have to go dogging through my pantry nor cabinet for spices. Everyone liked it so have the man around here some points. Is like to try addin some milk and basil next time I think maybe a simple “bisque?” Regardless it’s an easy 3 step recipe to fine tune to your own liking.

  • Terence Maher July 26, 2017, 6:50 am

    so easy and excellent

  • Amanda July 21, 2017, 1:46 pm

    Can I chop up the onions into small pieces rather than blending it?

    • Joanne August 9, 2017, 6:02 pm

      Sure, although we really love the creamy texture once the onions are blended into the soup.

  • Kat June 29, 2017, 7:13 pm

    Love this soup, my kids are already asking for it again! It’s a perfect inexpensive and easy dinner, especially for those days I’m to tired to put a lot of effort into something, even though it sure tastes like I did! 5 stars!

  • KS June 19, 2017, 6:46 pm

    Easy to make and tasted great. Added some garlic and left out some onion, threw some parmigiana on it, awesome! Great recipe

  • mark st clair May 8, 2017, 4:02 am

    This is my 6th dish that I have attempted. Ya’ll are beyond awesome. With this recipe I was facing a rainy sunday, so I through everything togeather in a pot, walked away to do laundry(or whatever unmemorable sunday task was needed) came back snuggled up with a bowl of tomato soup, a bagle, and a book. Turned my rainy sunday into a cozy sunday,thanks.

    I made this with some slight modifications. My son (age 7) asked for tomato soup (by tomato soup he meant Campbell’s condensed which I did not have)…so I went to the kitchen grabbed a can of tomato SAUCE because I used the last of my diced tomatoes for chili last week. I used an extra half cup of water, reduced the salt by half and added two tablespoons of white sugar. I strained the onions out before blending. He totally fell for it. 😊

  • Kristina April 15, 2017, 2:11 pm

    This was a good base. I’ve never made tomato soup before but have been really into it lately and am frankly sick of spending money at the grocery store soup bar. I opted to blend it all at the beginning because I was too scared to end up with a mess and don’t have an immersion blender. I used a can of crushed tomatoes and added a ton of basil because I just love it, and my plant needed a trim. I also added some heavy cream. Overall, a good starter recipe that you can easily add things to in order to fit your taste. Thanks!

  • Kelly B. April 5, 2017, 7:46 pm

    Do you have the carb count on this recipe?

    • Joanne May 16, 2017, 1:31 pm

      Hi Kelly, you are in luck! We just added nutrition facts. If you scroll to the bottom of the recipe, you should see the carb content there.

  • Mindy Jo April 3, 2017, 1:26 pm

    I wonder what I can use instead of butter? I am on a heart healthy/diabetic diet and am having a hard time finding recipes that are without butter, sugar or both. Is there an alternative?

    • Joanne May 16, 2017, 1:32 pm

      Olive oil can be used in it’s place and if you are hoping to cut some of the fat, reduce it a little.

      • Ryan July 19, 2017, 2:13 pm

        Olive oil is unsaturated, and a little more heart healthy than butter, but you’re not cutting the amount of fat. One tablespoon of oil is denser than a tablespoon of butter and has more calories. Not a bad substitute though. The other option is to just use less butter. Or maybe a dash of gelatin? It thickens it without adding fat, much like making broth with bones.

  • Barbara April 2, 2017, 11:00 am

    Making this today for the 3rd time. Love, love, love.

  • J March 31, 2017, 7:01 pm

    I made this for my family and they thought it tasted more like a tomato sauce. Adding pepper didn’t help much. I paired with grilled cheese and thought it would be an easy meal. Not too sure what I could have added to have it taste more like tomato soup.

    • Joanne May 16, 2017, 1:34 pm

      Hi J, I’m personally in love with this soup as-is, but you could swap the water for broth (chicken or vegetable) or add in a few more veggies (like carrot and celery).

  • Janet Moore March 28, 2017, 10:30 pm

    I love this soup. I make it using fire roasted tomatoes, a whole onion, and organic low sodium chicken broth. It is delicious! Thank you for posting it!

    • Debra June 19, 2017, 1:39 pm

      I am going to try this tomato soup by adding fresh herbs , 1/4 cup red burgundy wine , 1/2 cup chopped carrots , 1 chopped onion , majestic basil garlic ( look on website) and no salt or sugar organic tomato sauce .
