Oddly enough, it's my middle son who is soup obsessed. Ironically he is also one of my tougher eaters, so anytime I can get veggies into soups he likes I call that a mom win.
This vegan cauliflower soup really is a win-win-win-win though. The kids (well ⅔) love it, it's super simple to make, it can be made ahead of time, and it's full of healthy, whole food, plant based ingredients!

Preparation tips
Before you get to cooking this creamy soup, make sure to check out these helpful hints:
- This recipe as is will make a thicker bisque type texture. You can adjust the amount of broth for how thick or thin you prefer it.
- Depending on the salt content in the beans and broth, you may want to adjust how much salt you add in.
- I used red potatoes but any starchy potato will work, just don’t use sweet.
- Do not boil the potato to cook it or it will have too much moisture. I cooked it in the microwave (time saver!) but you can bake it too.
- If you prefer to roast the cauliflower for a more robust flavor, roast at 450 F/ 230 C for about 25 minutes until brown and crisp.
- If you don’t have a high speed blender, soak the cashews overnight to soften them. You can also boil them for 20-25 minutes if you forget. Another method is using a coffee or spice grinder to grind them dry (not soaking) into a very fine powder.
Make ahead and storage tips
This recipe for vegan cauliflower soup can be a real time saver! Prepare it ahead of time so all you have to do is heat and serve. Or, make enough for leftovers for an easy lunch the next day!

Healthy Vegan Cauliflower Soup Recipe
Equipment
Ingredients
- 1 cup chopped sweet or yellow onion
- ½ - 1 teaspoon sea salt , adjust depending on salt in beans and broth
- 3 cloves garlic , chopped
- Drizzle of olive oil , or broth if you don’t use oil
- 1 head cauliflower , about 2 pounds once cleaned and chopped into larger pieces
- 4 cups broth , low sodium if needed (see note)
- 1 cup raw cashews , see note
- ½ cup cooked potato , see note
- ½ cup cooked white beans , drained and rinsed from can
- 1 tablespoon lemon juice
Optional toppings:
- Parsley
- Thyme
- Vegan Parmesan
- Ground black pepper
- Saved browned cauliflower
Instructions
- Sauté the onions and salt with oil or broth until soft. Abut 5 minutes.
- Add the garlic and sauté for 1-2 minutes.
- Add the cauliflower, saute for about 6-8 minutes until browning. You can also roast the cauliflower if you prefer but the soup has more flavor if you brown the onions for the caramelized taste, so it takes more pans to cook the cauliflower in the oven but it is an option.
- Put the top on the pan and allow to cook for another 5-7 minutes until cauliflower is nice and soft.
- Add the cooked mixture into a blender, being careful not to burn yourself because it is hot. You can also save some of the cauliflower to use as a topping for the soup.
- Add in the rest of the ingredients and blend until nice and smooth. If your blender is high speed then it will blend it until nice and hot. If not, then you can warm in a pan on the stove.
- Serve!
Notes
- Adjust amount of broth for how thick or thin you prefer it. This will make a thicker bisque type texture.
- If you don’t have a high speed blender, soak the cashews overnight to soften them. You can also boil them for 20-25 minutes if you forget. Another method is using a coffee or spice grinder to grind them dry (not soaking) into a very fine powder.
- I used red potatoes but any starchy potato will work, just don’t use sweet.
- Do not boil potato to cook it or it will have too much moisture. I cooked it in the microwave but you can bake it too.
- If you prefer to roast the cauliflower, roast at 450 F/ 230 C for about 25 minutes until brown and crisp. I opted to pan saute so that I had less pans to clean but roasting yields a great flavor as well.

Laura Colvin
Hi, thanks for posting this recipe. I looked at the nutritional info and wonder where the 1 gram of cholesterol comes from?
veggiesdontbite
Hi Laura! It's from the cashews. There is some saturated fat in cashews. You should always talk to your doc if you must avoid saturated fat, but in general the healthy qualities that cashews give outweighs the small amount of saturated fat they have.
Naomi
Would this freeze ok?
veggiesdontbite
Hi Naomi! Yes! It definitely would!
Kathy
Hope you Can help. This soup sounds wonderful. At our retirement home we make a soup night. I need this recipe to equal 10 quarts of soup.can you help me.
veggiesdontbite
Hi Kathy! Thank you so much! So this makes about a 4 quart pot full. Not to the top but mostly full. If you go to the recipe where it says 4 quart pot nest to servings, you can hover and click on the arrows to increase the servings until you get 10. That will automatically adjust how many ingredients you need! I would maybe do 11 or 12 quarts just to be safe you have enough.
