As far as vegan soup recipes go…this one should be on your radar…
My vegan cauliflower soup recipe with roasted cauliflower, you will love it! it’s so creamy, super easy and tastes amazing!! It has a lovely hearty chowder consistency without the addition of potatoes and you’ll be hard pressed to believe it’s vegan!
You’ll be amazed that by just roasting the cauliflower, adding a few simple healthy whole food ingredients, carrots, celery, onions, spices, nutritional yeast and my secret flavour ingredient for vegetable stock- better than bouillon vegetable base! You end up with a healthy comforting bowl of cauliflower soup with top notch flavour!!
There’s no coconut milk, plant milk or cashews, just partially blending the soup creates such an amazing texture none of the cream options are needed!
Lovely for lunch or a lite dinner. Great family meal! Perfect cozy soup for fall, winter or anytime really! My daughter says she wants my potato leek soup next - ahh! wow one at a time sweetie ❤️ lol
How to make Roasted Vegan Cauliflower Soup:
(for full recipe instructions and ingredients see recipe card at end of post)
Preheat oven to 425° Line a large baking sheet with parchment.
Slice the head of cauliflower down the middle lengthwise and cut out the core. Pull off the florets and cut into slices. Add to the baking sheet. Drizzle over the oil and a pinch of salt and pepper. Toss everything together (I use my hands) and spread evenly on the sheet pan.
Bake for 35 minutes tossing halfway through cooking. When cool enough to handle give it all a rough chop
When the cauliflower is almost finished baking start the soup: Set your soup pot or Dutch Oven over medium heat. Add the onions, carrots, celery and garlic, oil and pinch of salt and pepper. Saute for 5 minutes or so until veggies are softening.
Now add the water, bouillon, nutritional yeast, salt, spices and roasted cauliflower (reserve lemon juice until the end of cooking) Bring to a boil on high heat. Cover reduce to a simmer and cook for 10 minutes or so until the veggies are tender.
Remove 4 big ladles of soup (4-5 cups) and puree in blender. Pour back into soup. Season with salt and pepper, stir in the lemon juice. If soup is too thick add a splash or two of vegetable broth. Enjoy!
Serve with my no knead artisan bread for a tasty lunch or lite dinner!

I made this for supper tonight and it turned out great. The cauliflower only needed about 20 minutes in the oven though, glad I checked on it or it would have burnt. I also left the soup all chunky, at my hubby's request. My son however wanted his pureed, lol! It was quite tasty. We ate it with my homemade whole wheat bread. I will definitely put this soup into my recipe rotation.

Just made this and absolutely loved it! I didn’t purée it. I planned on it, but it was so good I just started eating it.

Question. I just made this and I made a double batch. I am not new to cooking and soups are my favorite thing to make. I followed the instructions and used to heads of cauliflower, because I was doubling the recipe. When I blended my soup, it
wasn’t thick, at all. It was very runny. I have made other vegan soups, that require blending, to add texture/creaminess to the soup. Maybe, I needed more cauliflower? Your pictures look like you have a lot of veggies in, even after bending, and mine had very little. I used 9 cups of water (since I doubled the recipe), so I am just curious about your thoughts. Anyhow, even though it was runny (like a normal soup), it was very good. The flavor was amazing, I just want to get the texture right. Thanks!
Verna
Hi Tristen I haven't doubled the soup before- if you're finding it to thin just puree more of the soup, simmer longer, or add less water. It is not a super thick soup to begin with. Hope that helps and happy holidays to you!:) and glad you enjoyed it!

Simple to make and tastes amazing with bread and vegan butter 😍

Thank you so much! appreciate the feedback!

My boyfriend, who intensely disliked cauliflower, LOVES this soup! Me too! I didn’t have celery salt, so I added celery seed and salt. I also forgot the lemon juice the first time; when we added it the second time we decided the soup is perfect without it! I made it in the Ninja Foodi with pressure cooker, and that worked great. I blended about 3/4 of the soup for a creamier texture. This is a WINNER!!!
Verna
So happy you all enjoyed it and thank you so much for your feedback!
Annie

Mallory
Loved this soup so much!! Quick question, when it says that a “serving” is approx 159 calories, what exactly would that serving size be? Thanks!!!
Verna
When calculating the nutritional info that is what was determined and it is approximate. Thrilled you enjoyed the soup Mallory! Feel free to leave a rating next tine it is so helpful. Have a wonderful day!
Lindsay
Hey! Definitely making this soup tonight regardless, but celery salt is really hard for me to find- will omitting it drastically take away from the good flavor? Substitution of celery salt seems super weird, but I really don’t know! 😀
Verna
I'm sure it will still be tasty without celery salt, add in some chopped celery leaves along with chopped celery if you have them. Enjoy Lindsay!
Magi
