Ingredients
You’ll need just a few simple ingredients to make this soup. Below is an overview of the ingredients and any substitutions you can make.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.
- Broth: Any store-bought or homemade carton or cubes work. I usually just use bouillon cubes since they’re easy to keep on hand in the pantry.
- Coconut Milk: You can use full-fat for a rich, creamy soup or swap it for light coconut milk to reduce the fat in the recipe.
- Ginger: If you don’t have fresh ginger on hand, use 1 tsp ground ginger.
- Turmeric: If you don’t have turmeric on hand, mild yellow curry powder also works.
- Veggies: The recipe calls for carrot, cauliflower and sweet potato but the amounts don’t have to be exact. If you’re short on one, add a little more of the others.
How to Make Cauliflower Sweet Potato Soup
Step 1. Add the onion, garlic, ginger, carrot, cauliflower and sweet potato to a large soup pot with 1/4 cup of the vegetable broth.
Saute over medium heat until fragrant and starting to soften. This should take 7-10 minutes. If the mixture is getting dried out or starting to stick, add another splash or broth.

Step 2. Stir in the turmeric and cook for a few more minutes.

Step 3. Add the broth and simmer until the cauliflower and sweet potato are tender. This should take about 20 minutes. Stir in the coconut milk.
Step 4. Either transfer 1/2 to 3/4 of the soup to a blender and process until smooth or carefully use an immersion blender right in the pot to blend some of the soup. If blending in a blender, be sure to let the steam escape as you blend. If you want a completely creamy soup, feel free to blend it all.

Pour the blended soup back into the pot and serve right away topped with roasted chickpeas, fresh cilantro and a dash of lime.

Roasted Chickpea Option
Crispy roasted chickpeas are an optional topping that add some fun crunch and texture. To make:
- Preheat oven to 400 F.
- Add 1 can of drained, rinsed and dried chickpeas to a baking pan and and drizzle with 1/2 tsp olive oil.
- Add salt and pepper, or any spices you like such as cumin, curry powder etc.
- Roast for 30-40 minutes.
- Use some for the soup then let the leftovers cool completely on the pan before storing for later use.

Storing
- Fridge: Let cool then store in a sealed container for up to 5 days.
- Freezer: Let cool then store in a freezer-safe container (or multiple single-serving containers) for up to 3 months. Thaw overnight in the fridge.
- Reheating: Microwave or stovetop, stirring often, until heated to your preference.

This soup is just wonderful and really exceeded my expectations. I love how the turmeric is really the star of the show; often it is mixed with a bunch of other spices and loses its power, but this really highlights its flavor. I also love the addition of lemon and cilantro for serving. Yum!

I added that to the recipe, thanks. Add it after you’ve softened the veggies and just before you add the broth. Thanks!

Best and easiest soup EVER. I used butternut squash instead of the sweet potato just simply to lower the carbs a bit but the flavor was out of this world. I love this blog! Keep up the good work!!
Oooh amazing, sounds so good with butternut squash! Glad you enjoyed it and thanks for your comment.
