It's officially soup season so we are celebrating with a big bowl of Healthy Vegan Roasted Cauliflower Carrot Soup! This creamy soup is dairy-free, gluten-free, and flavored with curry powder for a flavorful & delicious vegan soup to cozy up with during Fall & Winter!
Steps to make carrot cauliflower soup
First, roast the vegetables
What makes this carrot cauliflower soup so good is roasting the vegetables before blending them with coconut milk and other ingredients.
For this recipe, I sliced the carrots into 1-inch pieces and then cut the cauliflower into florets. Then season the veggies with avocado oil, curry powder, garlic powder red pepper flakes, salt, and pepper before baking.
My biggest advice for this soup is to make sure to NOT undercook the vegetables. If you don't cook them until they are browned and starting to crisp, they won't blend well. Cooking the veggies at 400F for the full 30-35 minutes makes the roasted carrots and roasted cauliflower soft and easy to blend into a truly creamy soup.
P.S- for this recipe, I used my NordicWare Aluminum Baking Pans!
What curry spice works best in this recipe?
Ultimately, the curry spice you use in this recipe will affect the flavor of the soup so make sure to use a curry spice you know you like!
I used Spice Hunters Curry Seasoning which is a mixture of cumin, coriander, turmeric, ginger, cloves, red pepper, and black pepper.
You can likely find recipes online for homemade curry spices with these ingredients, but I personally prefer to buy them premixed. The reason for this is it helps me save money and reduce waste from buying large amounts of spices I don't cook with often (like cloves and coriander).
Blend the roasted veggies & coconut milk
Once the carrots and cauliflower are cooked, let them cool, then add them to a blender with the coconut milk. Blend until completely smooth and no chunks remain!
I'm still on the hunt for a great immersion blender, but I use the Kitchenaid K400 Blender which works great for soups. It's also the blender I used to make my Vegan Cream of Broccoli Soup so at this point it's basically my go-to soup blender!
Add veggie broth and simmer
The last step to making this soup is to add the blended veggies & coconut milk to a large soup pot with the veggie broth. The veggie broth helps to thin out this soup so it's not too thicken and also gives it a better flavor.
For this recipe, I used my Lodge Dutch Oven (sage green color if you're wondering!) to cook the soup and I used Pacific Foods Veggie Broth which is SO good and flavorful. If you're looking to make your own veggie broth, check out this recipe.
Best soup toppings
When it comes to soup toppings for this carrot cauliflower soup, I am a BIG proponent of crispy chickpeas!
If you are looking for a really good crispy chickpea recipe I recommend topping this soup with my easy Roasted Sriracha Chickpeas. You could also follow that recipe but season the chickpeas with curry powder instead to match the flavors of the soup.
Overall, a CRUNCHY or FRESH topping works best to give this soup more texture. Other good soup toppings include:
- Pepitas (raw pumpkin seeds)
- Fresh herbs (I used oregano, but any works)
- Hemp seeds
- Pomegranate or Crispy Kale (like I added in my Sweet Dumpling Squash Soup recipe)
- Homemade croutons or fresh breadcrumbs
FAQ & Substitutions:
Can I make this carrot cauliflower soup oil-free?
Definitely! You can boil or steam your veggies until they are soft and ate the seasoning directly to the soup. Alternatively, you roast your veggies on parchment paper or in a glass container without oil.
It doesn't taste quite as good (because there is less caramelization), but it still works. If the seasoning isn't sticking while you are trying to keep it oil free, try adding a little lemon juice or tamari to the veggies to help the seasoning stick.
Is there a substitute for coconut milk?
Keep in mind, coconut milk is what makes this vegan carrot cauliflower soup SUPER creamy.
However, if coconut milk is not accessible to you or you cannot eat it for other reasons, try subbing with unsweetened/unflavored soy milk or oat milk. I highly recommend either of these dairy alternatives as they are creamy and don't have as strong of a flavor as options like almond or hemp milk.
How do I store roasted carrot cauliflower soup?
Leftover soup will keep in a closed container in the fridge for 3-4 days or in the freezer for up to 1 month. When freezing soup, I recommend storing individually as you will have to defrost it before eating.
I hope you enjoy this comforting and Vegan Roasted Carrot Cauliflower Soup! Plus, get excited for even more soup recipes to come this winter.

- Preheat your oven to 400F. Chop the cauliflower into bite sized pieces and rinse and the carrots. Add them to a large baking sheet and toss with the avocado oil, curry powder, salt, garlic powder, turmeric, black pepper, and optional red pepper chili flakes.
- Roast the vegetables for 30-40 minutes until vegetables are soft inside and beginning to brown and crisp on the outside. Remove the vegetables from the oven and let cool to room temperature.
- Once the vegetables have cooled add to a blender with the can of coconut milk and blend until you smooth and no large chunks of vegetables are left. (If using an immersion blender, blend together with broth and tomato paste directly in pot).

- Leftover soup will keep in the fridge for 3-4 days or in the freezer up to 1 month. When freezing soup, I recommend storing individually as you will have to defrost it before eating.
- To make oil free, dry roast the vegetables on parchment paper or in a glass container instead. Veggies may need a little lemon juice or tamari to help seasoning stick.
- There is not a great substitute for coconut milk here (it provides the ultimate creamy flavor), but if you are okay with a less creamy soup sub 1:1 for soy milk or oat milk (unsweetened/unflavored)
- I topped this soup with curry roasted chickpeas based off my Sriracha Roasted Chickpeas recipe (just sub curry powder for sriracha and add in 1 teaspoon more oil)
