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.

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 ?

  • COOK
  • TOTAL

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

Directions

    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).

    Seems like an amazing quick soup! Cooking now. Do I cook it on medium or high for the 45 minutes?

    Reply
    • Joanne December 23, 2016, 7:02 pm

      The soup should be at a low simmer — I’d expect that to be medium-low to medium.

    This soup was just what I needed on a stormy winter’s night and only pantry staples required! I’m passing the recipe to friends and family.

    Recently made this soup and I love it… so simple and easy but I feel like it’s a little too salty for my taste, what would you recommend for that?

    Can I blend the tomatoes before cooking instead of after? My blender does not have a removable insert in the top.

      Yes, but you should also finely chop or blend the onion as well.

    Simple and delicious! I stumbled upon this recipe after I went to grab a can of tomato soup from the cupboard, and there wasn’t any.
    My son had just come home from a long, cold and rainy weekend of camping with his Boy Scout Troop. All he wanted was a tuna melt and tomato soup so he could warm up and get his belly full.
    I had all of the ingredients on hand, so I gave it a shot. I added fresh basil, a tiny drizzle of olive oil, a generous pinch of crushed red pepper and a little fresh ground black pepper. It was absolutely delicious!
    I’ll never buy canned tomato soup again. I’ll just grab a few extra cans of tomatoes to keep on hand.
    Thank you for sharing such a simple and delicious recipe.

    I have to have no salt so we used tomato sauce with no salt added. It was delicious. But next time I might mix a little milk or cream and half water. We doubled the recipe and it’s almost gone. Thanks so much.

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

      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.
