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?

What Our Readers Are Saying

“WOW!! What a delicious and easy tomato soup, my three and one-year old were as thrilled as my husband and I were.” – Ashley

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.

    This recipe is so simple yet SO delicious! I added several cloves of garlic and Italian seasoning to the melted butter and onion, I used canned tomato sauce and it turned out amazing. This site always has the most simple and amazing recipes thank you!! Must try!

  • Joyce Ellen September 14, 2021, 7:00 pm

    Great soup! I modified it a little — added basil and a light dusting of chili flakes. I used crushed tomatoes. It was yummy just like this, and after it cooled I added cream to it which made it even better!

  • Karen September 8, 2021, 7:10 am

    Just made this soup absolutely delicious, if using fresh tomatoes do you add the same amount of water, onion and butter 😀😀

  • SouthernMomma2mb September 5, 2021, 1:10 pm

    OMG! This soup is amazing and so easy. My daughter loved it. Will be making this again and again. Next time I’ll make it in a bread bowl.

  • Linda Harootunian August 26, 2021, 8:24 pm

    This is the GREATEST tomato soup recipe EVER!! SIMPLE, QUICK, DELICIOUS!! You only need 2 pounds of fresh tomatoes for a batch, not 12 pounds with a ton of fancy spices!! 3 simple ingredients you probably have in your kitchen. You don’t have to can them and put them in the hot water canner, FREEZE them in a quart zipper bag! It’s wonderful!! Thank you!

    • Karen September 8, 2021, 7:13 am

      I agree absolutely delicious do you think I could use some frozen tomatoes. I’ve got as I got loads off the allotment

  • carmen gonzalez August 9, 2021, 9:27 am

    You can tell you both cook from the heart and your gut! This is awesome! Chefs make it soooooo complicated and use 400 ingredients you have to travel to Provance, France to get. Thanks for really wanting to share with folks the simple joy of cooking and cooking with gusto!
