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.

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 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).

    I made this last night for my 10 year old grandson. He enjoyed dunking his grilled cheese sandwich into it. It is amazingly good and so simple to make. I used Whole Foods 365 organic canned whole tomatoes and organic vegetable broth.

    This soup is amazing, I will never open a can of tomato soup again! I did add 2 tablespoons of pesto sauce to give it a tomato basil flavor and instead of butter used light butter with canola oil just decrease calories(especially in view of adding calories with the pesto sauce). Delicious hot or cold!

  • Kim February 10, 2018, 2:59 pm

    A-mazing! I was super hungover and was able to make this with just what I had in the fridge. I made it with the following modifications: small punnet of cherry tomatoes, 3 carrots, half an onion, garlic, butter, bay leaf, some water and salt and pepper. Whizzed it in the food processor after 40 minutes and then added a bit of cream. Perfect with a grilled cheese sandwich. This will definitely be my go-to tomato soup recipe from now on, thanks!
