Easy Three-Ingredient Tomato Soup
My favorite 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
How To Make The Easiest Tomato Soup From Scratch
This simple homemade tomato soup is quick, easy, and insanely delicious. It is excellent with canned tomatoes, but you can also use fresh tomatoes. Tips for canned and fresh tomatoes are found in the recipe below. If you love quick, no-fuss recipes, this is it! If you love roasting tomatoes, try our roasted tomato soup!
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.
We love serving this with a grilled cheese sandwich, but a slice of this rosemary focaccia bread is also an excellent idea!
Making The Soup
Here’s how to the best (and easiest) tomato soup
Add water or broth and simmer. Bring everything to a low simmer, add some salt and leave it alone for about 40 minutes.
Watch our video above and see how creamy it gets. That’s thanks to the butter.
Blend. I 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?
What Tomatoes Should I Use
This soup is excellent with canned tomatoes. Just like when making our favorite red pasta sauce, I love using 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.
You can also use fresh tomatoes. You will need 10 to 12 whole tomatoes (or about 2 pounds). It’s best to peel them, but we have made the soup with unpeeled tomatoes.

Can I add cream? Yes, although, with the butter in this recipe, only a small splash of cream is needed.

Easy Three-Ingredient Tomato Soup
You only need three main ingredients to make this velvety, rich tomato soup recipe. This, friends is your new favorite weeknight meal.
Watch Us Make the Recipe
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, see notes for fresh tomatoes
1/2 teaspoon fine sea 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 1/2 teaspoon of salt. Bring to a simmer. Cook, uncovered, for about 40 minutes. Stir occasionally and add additional salt as needed.
Blend the soup, and then season to taste. The soup doesn’t need to be ultra-smooth, some texture is a nice touch. An immersion blender does make quick work of this, or you can 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 to release some of the steam and prevents the blender lid from popping off (which can be a big, hot mess).
Adam and Joanne's Tips
- Can I use fresh tomatoes? Yes. If you want to use fresh tomatoes, you will need 10 to 12 medium tomatoes (or about 2 pounds). You can peel them, but we skip this step since we will be blending the soup in the end anyway.
- Can I make this vegan? Yes, olive oil is an option or coconut oil instead of butter. Coconut oil might sound odd but the light coconut flavor with onion/tomatoes is pretty delicious.
- Can I add basil? This soup is delicious with and without basil. Adding a handful of fresh basil at the end before blending the soup is a fantastic idea.
