A healthy, easy and deliciously complex vegan cauliflower soup made lusciously creamy with celery root and bright with fennel and ginger. It’s quick and light, making it a great weeknight dinner or lazy weekend lunch.
Soup weather has officially arrived!!!
And of course for my cauliflower soup I choose to use…purple cauliflower! Cause that’s my jam. <3
And if ya don’t know that by now…then ya def should! When given the option between the purple and non-purple version of a veggie…I’ll always be the gal going for the purple.
The other day, I was chatting with some catering clients on the phone about the menu for their upcoming event. They asked me: does your food really taste as good as it looks? Well…I sure like to think it does! Try this recipe and you can be the judge :).
Why this Recipe Works:
- Roasting the cauliflower in high heat caramelizes the exterior, bringing out a touch of nuttiness for greater depth of flavor.
- The addition of fennel brightens up the soup and the ginger adds a kick of spice to balance out the rich flavor.
- This soup tastes even better the next day and freezes well (so feel free to double or even triple the quantity to have leftovers).
- The addition of celery root luscious creaminess to this dairy-free soup and brings earthy buttery notes.
Cauliflower, Celery Root and Fennel Pair Beautifully.
One of the most effective ways to pack depth of flavor into a soup is to take the extra step of roasting your veggies before adding them to the pot.
I’m going pretty hard on sharing all my purple-licious food recipes first cause I want you all to know that YES my food DOES taste as good as it looks. And I’m gonna let ya in on a little secret: purple cauliflower taste just like non-purple cauliflower (any difference is *very* subtle). So if you’re having a hard time imaging a purple soup not only looking damn good but actually tasting good too then just think of it as a Cauliflower, Celery Root & Fennel soup. That’s sounds yum, right? Right.
How to Make this Recipe
- Preheat oven to 450 F and chop all your veggies.
- Roast the cauliflower and sweat the onion, followed by celery root, fennel, ginger and garlic and sauté.
- And roasted cauliflower, celery root to the onion pot.
- Simmer for 25-30min.
- Puree.
- Ladle into soup bowls and sprinkle with any toppings your heart desires and enjoy!
Please see my (quasi) step-by-step guide with the corresponding pics below.
Celery root is one of the most underrated veggie… prob cause it’s looks so gnarly…. hehehe.
I’m also gonna let ya in on another little secret if you’re trying to get your soup to look exactly how mine does in the pic. Veggie stock tends to be brownish, so I’ll drain the soup in a colander before blending it up for the pic, then pour the rest of the stock back in. That’s purely an aesthetic strategy so that the veggie stock doesn’t dilute purple color of the soup. Disregard if you’re not too color-concerned (or if you’re not using purple cauliflower, which is a totally valid option!) I obviously completely understand if you don’t have a purple-itis like I do 🙂
I’m keeping it simple and using fresh ginger and garlic and skipping spices, but feel free to have fun playing around with different spices if you’d like and let me know about it in the comments below.
Cooks Tips:
- It’s crucial to roast the cauliflower at high heat to get the full depth of flavor.
- Veggie stock can easily be swapped for chicken or beef stock or even water if you’re really in a pinch.
- If you don’t have a blender and immersion blender will work or stain liquid out and put all the veggies in a food processor then stir the liquid back in (hey, not perfect but if ya don’t have a blender I still want ya to be able to make this soup).
- Once cooled you can store this soup in the fridge 3 days or freeze in suitable containers for 3-6 weeks.
- You can add red pepper flakes to add a kick of spice
- If you're using purple cauliflower, adding a splash of vinegar will turn the soup purpler!
The base is cauliflower, celery root, and fennel, and the aromatics are onions, garlic, and ginger.
I’m giving you permission to leave out the fennel or celery root if you forgot to pick it up and use only 2 of the 3 aromatics if ya need to. Just don’t leave out the cauliflower or it won’t really be a cauliflower soup at all. Have fun. Play. Make soup on a cold day and stay cozy.

Looks so beautiful and luscious! Can you please share what you have used on top for presentation? Is that circles of radish arranged on top? And what are the purple and orange coloured sprinkles?
Yes absolutely! Those are radishes and the sprinkles are salt and bee pollen :). And thanks so much for the super sweet feedback Samia!
