  • Our recipe for tomato soup has 3 ingredients (plus water and salt).
  • Everything is tossed into a pan — no browning, no hovering over a stove.

Our family loves serving tomato soup with a grilled cheese sandwich. A slice of this rosemary focaccia bread is also an excellent idea! For another spin, try our easy favorite roasted tomato soup!

How to Make the Best (and Easiest) Tomato Soup

You will need three main ingredients to make this tomato soup: butter, tomatoes, and onion. These three ingredients, plus water (or broth) and salt, combine to make one of the best bowls of tomato soup we’ve made.

Our tomato soup recipe pulls inspiration from Marcella Hazan’s famous tomato sauce, a simple yet genius dish with simmered tomatoes, butter, and onion. She removes the onion before serving the sauce over pasta.

We use the same three ingredients to make our soup, but add water and blend everything (including the onion) before serving. The result is a creamy, flavorful soup rivaling almost every recipe for tomato soup we’ve tried.

I’m still amazed at how easy this soup is and how delicious it turns out. If you are skeptical about such a simple recipe, read through the reviews at the bottom of this page. So many of our readers have fallen in love with this easy soup recipe.

To make the soup, you are going to add butter, half an onion cut into large wedges, and a large can of tomatoes to a large pot. If you want to use fresh tomatoes, you can. We’ve included tips for using them in the recipe below.

Tomato Soup Ingredients

Bring everything to a low simmer and cook for 40 minutes. You can see from the photo and our video that our tomato soup becomes creamy. That’s thanks to the butter. The onions also soften, making the soup even more creamy when blended.

Cooking tomato soup

Blend until smooth. An immersion blender is helpful, but a blender works perfectly fine. Adjust the soup with salt and pepper, then grab a bowl and that grilled cheese sandwich I mentioned. This tomato soup is also excellent, topped with homemade croutons or served next to a slice of homemade focaccia or buttery garlic bread.

The Best Tomatoes to Use

I love making this tomato soup with canned tomatoes. They are available year-round, which means we can enjoy delicious soup anytime. I reach for whole peeled or crushed San Marzano tomatoes and am always pleased with tomatoes from Muir Glen.

If you have access to fresh ripe tomatoes, you can use them in this soup recipe. You will need 10 to 12 whole tomatoes (about 2 pounds). I do not peel them for this soup (you can, but I like to keep things easy).

Frequently Asked Questions

Can I make this a vegan tomato soup? For vegan tomato soup, swap the butter in our recipe for plant-based butter or use extra-virgin olive oil. You can also use coconut oil. The light coconut flavor with onion/tomatoes is pretty delicious.

Can I add basil? For a tomato basil soup, just before blending your soup, add a handful of fresh basil leaves. Or, use 1/4 teaspoon of dried basil.

Can I make creamy tomato soup? As written, this soup does have a creamy texture (thanks to the butter). Add a splash of cream after blending for an extra creamy, rich tomato soup.

Make Ahead Tips

This tomato soup recipe is perfect for making ahead of time. Store homemade tomato soup in an airtight container in the fridge for up to three days or freeze for up to three months.

Makes 2 generous servings

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 ½ cups water, low sodium vegetable stock, or chicken stock

1/2 teaspoon fine sea salt, or more to taste

Directions

    1Melt the butter over medium heat in a Dutch oven or large saucepan.

    2Add onion wedges, water, tomatoes with their juices, and 1/2 teaspoon of salt.

    3Bring to a simmer. Cook, uncovered, for about 40 minutes. Stir occasionally and add additional salt as needed.

    4Blend the soup, and then season to taste. The soup doesn’t need to be ultra-smooth; some texture is nice. 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 fill the blender less than you usually would since the soup is so hot. We like to remove the lid’s center insert and cover it with a kitchen towel while blending — this helps 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

  • Fresh tomatoes: Use 10 to 12 medium tomatoes (2 pounds). You can peel them, but we skip this step since we will blend the soup anyway.
  • Vegan substitution: Substitute the butter for plant-based butter or extra-virgin olive oil.
  • Fresh basil: Add a handful of fresh basil before blending the soup.
  • Nutrition facts: The nutrition facts provided below are estimates. We have used the USDA database to calculate approximate values. We have omitted salt since you will need to add to your tastes.
