I’ve been on Thai curry kick lately, so I thought it would be fun to create a twist on tomato soup! Coconut milk makes this soup rich and creamy and I love the spiciness of the red pepper flakes. I sprinkled extra on top because I liked the heat! This recipe comes together quickly and easily.

Tips for Thai Tomato Soup

  • Be sure to shake the coconut milk before you open it. Coconut milk tends to separate and shaking it will mix it up and make it easier to reserve some for the topping.
  • When chopping cilantro, feel free to chop the thin stems with the leaves. Discard the larger stems near the bottom of the herb.
  • If you don’t like spicy flavors, skip the red pepper flakes. The red curry paste has a small amount of spice, but the coconut milk will make it mild enough for sensitive palates.

Substitution Ideas

  • For a lower fat option, you can use lite coconut milk. It won’t be as rich and creamy, but it’ll still have a coconut flavor.
  • For a lower sodium option, use low sodium vegetable broth. I prefer “not chicken” style broth for this recipe.
  • You can substitute crushed tomatoes or fire-roasted tomatoes for the diced tomatoes.

How to blend hot soup

  • I like to use an immersion blender because it’s a little less messy and I think it’s easier to achieve the perfect consistency. I like this soup a little chunky so an immersion blender lets me combine all the ingredients without making it perfectly smooth.
  • If you don’t have an immersion blender, you can still blend this soup in a blender. I recommend working in two batches and letting the soup cool slightly before transferring, just so you don’t burn yourself! Remember to allow steam to escape from the blender so the soup doesn’t explode!
  • Do NOT try to blend the hot soup in a bullet style blender like a Nutribullet or Magic Bullet. The steam must escape or you risk an explosion!
