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).

    Can you make this with fresh tomatoes? or will it be too watery? Thanks

      Hi AnnMarie, You can definitely use fresh tomatoes. The large can of tomatoes holds about 3 cups of tomatoes. You could peel the tomatoes (the easiest way to do this is to dunk them into boiling water and then into ice water).

    So delicious. I added sugar because the tomatoes were really acidic. Towards the end I also added parsley and garlic.

    This was sooo good!! I have made it twice now, the 2nd time I used orange tomatoes, 1 jalapeno, vidalia onion, and half an orange bell pepper! Then I added rosemary and basil right before I blended it. Divine, so love this recipe!!

    I’ve made this a few times already. Sometimes, I add a little sugar and balsamic vinegar or heavy cream, milk or half-n-half just to have some variation. Tomatoes are one of my favorite fruits. I try to make my meals from scratch as much as possible so that I know exactly what’s in it.
    Canned tomato soup is good in a pinch. But, to avoid that, I make 2 batches of soup, leave some for to refrigerate and the rest in the freezer in small bowls for faster thawing. I make a grilled cheese using different cheeses like smoked Gouda, Gruyère, Swiss, extra sharp cheddar, Muenster, Mozzarella and American sliced cheese and more. It’s fun to mix a few cheeses, too. Cut them into sticks and dipped them in a hot bowl of homemade tomato soup. Great comfort food. Great for enjoying on cold rainy days.

    Want to make this recipe soon as I have made Marcella Hazan’s tomato sauce and thought it tasted like really good tomato soup! My question is could I substitute milk for the water to make it a bit creamier?

      Hmm, that’s a good question. I think I’d stick with the water then add a splash of milk or cream at the end.

    How important is it to use salted butter??? Thanks in advance

    Reply
    • Joanne August 3, 2018, 3:46 pm

      Not very important. Just remember that salted butter will mean you don’t need to add as much salt to season the soup.

    So easy, quick and delicious. My four year old would eat the whole batch if I let her. For anyone following a plant based diet or with a dairy allergy/intolerance just sub avocado oil. You won’t even know the difference. I also added about 1/4-1/2 tsp of minced garlic that I had left on my cutting board.
