How To Make The Easiest Tomato Soup From Scratch

This simple homemade tomato soup is quick, easy, and insanely delicious. It is excellent with canned tomatoes, but you can also use fresh tomatoes. Tips for canned and fresh tomatoes are found in the recipe below. If you love quick, no-fuss recipes, this is it!

Easy Three-Ingredient Tomato Soup

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.

We love serving this with a grilled cheese sandwich, but a slice of this rosemary focaccia bread is also an excellent idea!

Making The Soup

Here’s how to the best (and easiest) tomato soup:

Combine butter, onion, and tomatoes. 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.

Add water or broth and simmer. Bring everything to a low simmer, add some salt and leave it alone for about 40 minutes.

Watch our video above and see how creamy it gets. That’s thanks to the butter.

Blend. I 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?

This soup is also amazing topped with homemade croutons or served next to this easy buttery garlic bread.

What Tomatoes Should I Use

This soup is excellent with canned tomatoes. I love using 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.

You can also use fresh tomatoes. You will need 10 to 12 whole tomatoes (or about 2 pounds). It’s best to peel them, but we have made the soup with unpeeled tomatoes.

A Quick Recap

This is your new favorite weeknight meal. Promise.

  • 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?

Frequently Asked Questions

Can I make this tomato soup vegan? Yes, olive oil or a plant-based butter is an option. You can also use coconut oil. It might sound odd but the light coconut flavor with onion/tomatoes is pretty delicious.

Can I add basil? This soup is delicious with and without basil. Adding a handful of fresh basil at the end before blending the soup is a fantastic idea.

Can I add cream? Yes, although, with the butter in this recipe, only a small splash of cream is needed.

Can I make this soup in advance? Yes! Store homemade tomato soup in an airtight container in the fridge for up to three days or freeze up to three months.

Easy Three-Ingredient Tomato Soup

  • PREP
  • COOK

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

Makes 2 generous servings

Watch Us Make the Recipe

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, see notes for fresh tomatoes

1 ½ cups water, low sodium vegetable stock, or chicken stock

1/2 teaspoon fine sea 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 1/2 teaspoon of salt. Bring to a simmer. Cook, uncovered, for about 40 minutes. Stir occasionally and add additional salt as needed.

    Blend the soup, and then season to taste. The soup doesn’t need to be ultra-smooth, some texture is a nice touch. An immersion blender does make quick work of this, or you can 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 to release some of the steam and prevents the blender lid from popping off (which can be a big, hot mess).

Adam and Joanne's Tips

  • Can I use fresh tomatoes? Yes. If you want to use fresh tomatoes, you will need 10 to 12 medium tomatoes (or about 2 pounds). You can peel them, but we skip this step since we will be blending the soup in the end anyway.
  • Can I make this vegan? Yes, olive oil is an option or coconut oil instead of butter. Coconut oil might sound odd but the light coconut flavor with onion/tomatoes is pretty delicious.
  • Can I add basil? This soup is delicious with and without basil. Adding a handful of fresh basil at the end before blending the soup is a fantastic idea.
  • Nutrition facts: The nutrition facts provided below are estimates. We have used the USDA Supertracker recipe calculator to calculate approximate values. We have omitted salt since you will need to add to your tastes.

    Can I make this recipe in an instant pot?

    • Joanne July 5, 2021, 5:44 pm

      Hi Patty, Yes, this soup can be made in your pressure cooker. We have not done this ourselves, so I am unsure of exact timing.

  • Jacquelyn January 20, 2021, 8:13 pm

    This soup was so simple, and SO flavourful. I was a skeptic… now i’m a believer.

  • Rick boyett January 20, 2021, 2:31 pm

    Ok this was crazy easy i did add pepper and a pinch of sugar it came out great

  • Debra January 19, 2021, 5:43 pm

    Ive made this twice now, with a couple changes. I double the recipe, let the onion carmalize in the butter with some garlic before adding the tomatoes and stock to add more flavor. I think using organic imported canned tomatoes makes a huge difference. I prefer making tomato soup in the summer when I can use fresh tomatoes, roasting them first…. but since it’s my favorite soup, it’s nice to have an easy go to recipe for winter. Thank you! It’s definitely on our dinner rotation!

  • hi January 19, 2021, 11:00 am

    i never comment, but i felt that this was absolutely necessary. the soup was sooooo easy and good. I stirred it every 10 mins. I added extra seasonings, such as black pepper and italian herbs. it came out perfect with grilled cheese 🙂

  • Gary January 14, 2021, 7:32 pm

    Ok, this is my second time making this awesome soup! First time I added cumin, chili powder and ground venison. YUM! Right now I’m am in the process of making up my second batch. I don’t usually follow directions so I didn’t this time either. Maybe the reason I got so many spankings as a child! This time I added sour cream and substituted whole milk for water. Few more minutes on the stove and it will be ready to throw in ninja. My idea for the next batch is going to be adding cut up jalapenos! Thanks for the inspiration!

    This recipe as-is was wayyy too acidic for us. We added a bit of baking soda at the end, and it really helped.

  • Reg Dunning January 8, 2021, 12:49 pm

    I made this soup today, exactly to the recipe, with one exception. I already had a half a sweet onion reserved, so I used that instead of a yellow one. I was satisfied with the result, although , I think a little Tomato paste would have helped the taste . I sampled the soup: with a dash of Cayenne: with a dash of Chili powder. Both served well, so YES, I will be doing this again!

  • Donna L Coats January 6, 2021, 4:19 pm

    This is delicious…my husband will not eat tomato soup, but I was so enthusiastic over this that he tried it and said I would eat this again…that’s high praise coming from him. I sauteed the inion first and I added basil. Love it. I have anpther batch on the stove right now. IThis time I put the sauteed onions into my blender and blended them with the tomatoes before cooking so I don’t have to deal with blending hot soup…I’m hoping it works well, I don’t see why it shouldn’t. Oh,another reason I’m so happy is that I’m on a low sodium diet, so I use sodium free ingredients and add NuSalt…it works for me!

  • Lynnie January 4, 2021, 5:46 pm

    Easy peasey! Out of this world delicious! Love, love it. Perfect comfort food with a velveeta grilled cheese. (Sorry, know that’s not very gourmet,or, healthy but reminds me of long ago and my mom.)

  • Jane January 3, 2021, 1:07 pm

    This is so good, and so easy. We make it every week. Even people who don’t like Campbell’s tomato soup love it. It tastes like real tomatoes.

    • Jane January 3, 2021, 1:08 pm

      Five stars. I’d give more if I could.

  • Kate Farris January 2, 2021, 4:18 pm

  • Dawn December 24, 2020, 12:40 pm

  • Jenn December 14, 2020, 2:25 pm
