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).

    Alright so this recipe is the bee’s knees, however here’s how you turn it up to 11! Add a can of beer, no joke a beer is the best replacement for the water or chicken stock. Also no pansy beer, if lite is in the name, just stop. I USED Hamm’s better than PBR or malt liquor. DO YOURSELF A FAVOR AND PUT A BEER IN YER SOUP!!!

    OMG, this was amazing just made it. I had to double the recipe though to get plenty for all of us. Now I did not have a can of whole tomatoes as is very difficult to find that here in the Yucatan. But tomato sauce is found in abundance. Add a bit of garlic to the onions, simmered as instructions. then when doing the last part of blending in the blender added a little heavy cream to it and a bit more sauce, then mixed together and heated it up a bit more. This recipe is good. So glad I was able to find
    this recipe online..

    Thank you for this recipe! OMG! I’m seriously leaving this comment in between dipping my grilled cheese in this AMAZING soup! So easy, yet full of flavor. My adjustments: Added 1 tsp minced garlic, 1/2 C milk, & 1 Bay leaf while simmering (removed before blending)! Did I mention, I don’t like tomatoes, but this is delicious! Thanks again!

      Did you use water or chicken stock when you add the milk to the soup?

    A friend forwarded me this recipe and shared that she added two garlic cloves, a few chili flakes and some herb de provence. it was superb!!! great with a grilled cheese sandwich. i added just a splash of evaporated milk to make it a bit creamy and also used a whole onion. absolutely delicious! soon to become a family favourite and so easy. you dont need to simmer 40 minutes. 25 minutes was plenty!

    I liked it, but kids did not. They said it tasted like spaghetti sauce. I have plenty leftover so I think I will add some more spices and possibly a little cream to smooth it a bit. Once they said spaghetti sauce, I kind of agreed, but still liked it.

    Made it – was easy and delicious without being heavy. Only used 2 tablespoons of butter but added garlic and used chicken broth (store bought) instead of water. Do recommend!
