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).

    This was absolutely delicious. I cooked mine in the crock pot. I just threw all of the ingredients in added fresh garlic and cooked on high for 4 hours, let it cool and then pureed it. Yummy!

    Made this last night and it was heavenly! I simmered two sprigs of rosemary in there (took them out before blending) and it added so much flavor! Would definitely recommend that if you happen to have some around

    Does It taste different if using olive oil instead of butter? Thank you!

      Hi Jennifer, the butter makes it really creamy tasting, but olive oil should still work in its place.

    I thank you for this recipe. I love the tomato steak recipe my family has always made but most canned soups contain gluten or peppers. I do not respond well to either one. I tried it with one that didn’t and was not overly fond of it (or the price tag). This recipe worked beautifully. I did make it with fresh tomatoes, so I will try canned soon. We had A LOT of fresh.

    I love tomato soup but can’t abide the canned version. This is a quick recipe that tastes wonderful. I made it according to the directions. Will definitely Make it again.
