A super easy tomato soup!
I’ve been making this creamy tomato soup for my kids for years because it’s fast and healthy. My older son loves it, even though he’s not a fan of coconut milk or coconut flavor—so don’t let your anti-coconut bias deter you from making this homemade tomato soup recipe! If you want a super creamy texture, definitely use a powerful blender (like a Vitamix)—no one likes chunks in a creamy soup.
- Extra virgin olive oil, coconut oil, avocado oil: To keep this soup dairy-free, I use one of these cooking fats rather than butter to sauté the alliums.
- Leeks: I recommend using at least 2 cups of thinly sliced leeks (the white and light green parts only) because they add a fantastic sweet onion-y flavor. If you don’t have leeks, thinly sliced shallots or onions will also work. Don’t skimp on this part because the sautéed alliums add to the creaminess of the soup when you blend it all together!
- Garlic: The more the better, but six cloves is always a good amount.
- Fire-roasted canned diced tomatoes: Yes, grab CANNED fire-roasted diced or whole tomatoes (I love Muir Glen brand the best). Fire-roasted canned tomatoes add more depth and flavor to the soup without any fuss or muss. Don’t worry—regular diced tomatoes will work in a pinch. I know some of you may be tempted to use fresh tomatoes, but this pantry staple will save you both time and effort and the end result is terrific.
- Broth: Obviously, the better the broth, the better the soup! I use homemade bone broth or I buy Roli Roti or Bonafide Provisions at the store. If you want to make this soup vegetarian, use a high-quality vegetable broth.
- Coconut milk: To keep things dairy free, I use full fat coconut milk in place of heavy cream. My favorite brand is definitely Aroy-D that comes in green Tetra Pak containers at Asian grocery stores. If you absolutely despise coconut milk, you can definitely use another alternative milk but it may not turn out as creamy!
- Kosher salt
- Freshly ground black pepper
- Fresh basil: Top each bowl with thinly sliced fresh basil for a bright, herbaceous kick!
How to make Cream of Tomato Soup
Heat a large saucepan over medium heat. When the pan is hot, swirl in the extra virgin olive oil.
Add in the leeks and a sprinkle of salt. Sauté until the leeks are softened but not browned, about 3 to 5 minutes.
Next, add the minced garlic and cook for about 30 seconds, or until fragrant.
Turn off the heat and transfer the cooked leeks and garlic to a plate.
Dump the whole can of tomatoes, juice and all, into a high powered blender (I love my Vitamix blender)…
…and blitz on high until it’s smooth. (If your blender isn’t big enough, blitz the tomatoes in batches.)
Pour half of the puréed tomatoes into a medium saucepan…
…and add the softened leeks to the remaining tomato purée in the blender. Blitz the tomato purée and aromatics on high until the mixture is smooth. Pour the contents of the blender into the saucepan.
Add the broth and coconut milk.
Stir well and crank the heat up to medium high to bring the soup to a boil. Then, decrease to medium-low heat or enough to maintain a simmer for 10 minutes, stirring occasionally.
Taste the soup and adjust the seasoning with salt and pepper.
Ladle up the soup and garnish with fresh basil.
