17 Comments Do you love cauliflower and do you love celery root or celeriac? Then this cauliflower celeriac soup is for you! I like to serve it with flaky pan-seared salmon on top of the pureed soup. So good!

Tip from Simone
I made this cauliflower celery root soup with coconut milk. That’s one option! You can also skip the cream entirely, or use regular heavy cream or regular milk instead. I personally love the flavor of coconut, but not everyone does – so feel free to adjust it!
Recipe Ingredients
This cauliflower soup with celeriac is fairly simple in terms of ingredients, but here are a few helpful notes in case you want to switch things up:
- Leek – instead of onion I’m using leek for flavor this time. You can swap it for onion if you prefer. And honestly, garlic is good with everything.
- Cauliflower and celeriac – I use about half of each, but I added the weights because they can vary a lot in size.
- Coconut milk – makes the soup extra creamy. Add it at the end of the cooking time and let it warm through. If you want to use cream instead, that works great. I’d use a bit less (about 100-150 ml / ½-â…” cup) and adjust to taste. If you need to keep it dairy-free, you can also use plant-based cream.
- Broth – I use chicken broth because it has more flavor than vegetable broth, but both work.
- Salmon fillet – I use fresh salmon, but this also works well with smoked salmon (which doesn’t need to be cooked). Hot-smoked salmon is also delicious!
How to Make Cauliflower Celeriac Root Soup
If you’ve made cauliflower soup before (like this cauliflower soup with crispy bacon) then it won’t surprise you that this one is just as easy.
Slice the leek into thin rings – I’m using leek instead of onion simply because I had one in the fridge. SautĂ© the leek gently until it softens, then add the diced celery root and cauliflower florets. SautĂ© briefly and then add the broth. Let it simmer until the vegetables are tender, which takes about 15 minutes depending on how large the pieces are.
Blend the soup with an immersion blender, add the coconut milk and let it heat through while you pan-sear the salmon until crispy. Serve with fresh dill.
FAQ Cauliflower Celeriac Soup
Yes. Replace the chicken broth with vegetable broth and leave out the salmon. For extra protein, try toppings like roasted chickpeas, sautéed mushrooms, or tofu.
Absolutely. Use heavy cream or cooking cream for a rich version without coconut flavor. Want it dairy-free but not coconut? Unsweetened oat cream works great.
You can freeze the soup without salmon (for up to 3 months). Leave out the coconut milk and salmon before freezing and add them after reheating for best texture and flavor.
Pan-sear the salmon before serving. Adding raw salmon to hot soup doesn’t cook it evenly. Smoked salmon, however, can be added directly!
Yes, but the soup will be chunky. You can also use a regular blender – blend in batches and be careful with hot liquids.
Great options include:
- Extra flaked salmon
- Crusty bread (or make your own croutons!)
- Rye bread with cream cheese
- Crackers with herbed cream cheese

Delicious and creamy soup and so easy to make!
Perfect timing for me. I’m doing Paleo and needing some good ideas right about now. It looks very comforting. A squeeze of lemon might be nice too.
O I didn’t know you are doing Paleo too at the moment Angela! This soup is wonderful and in fact now that I think about it; the original had a squeeze of lemon in it as well but I just totally forgot!
That’s such a pretty bowl with so much flavor in there. I love cauliflower and salmon together, and with a bit of coconut, that’s just pure bliss!
Thanks Gintare! It is indeed a delicious soup!
I love anything with celeriac or celery root as we call it here, and have yet to combine it with cauliflower until reading this recipe. The soup looks perfectly delicious and being so healthy is an added bonus.
Thanks Cathy and yes it is indeed a great combination!
Sorry to hear you are feeling uninspired, Simone, but let me tell you, this soup sure inspired me!!!
You sure did a fantastic job adapting Donna’s recipe! I say you should be uninspired more often đŸ˜‰
Thanks so much Sonia! đŸ˜‰ We decided to stop the whole30 and continue with ‘regular’ Paleo instead. Just so we can have something else in the morning. That breakfast really is my breaking point. We did eat chicken once for breakfast but it’s just not something I can stomach early in the morning. This morning we had quinoa flakes with some fruits and nuts and boy, that was delicious.. đŸ˜‰ So still on the healthy path, just a tiny bit more flexible.
Beautiful picture, and the soup looks pretty good too đŸ˜‰

Thanks Janie!
A refined tasting soup! That combination is wonderful. Celeriac is so fragrant and versatile…
Cheers,
Rosa
It is, isn’t it? I totally love celeriac except for the cleaning part..
Gorgeous, Simone! I love the light here – and I recognize that spoon đŸ˜‰
Hahaha… Yes I think the spoon might look familiar to quite a few people!
I love cauliflower soup and with salmon it’s the best! I used that spoon recently in a shoot too LOL! Oh good times & memories! I am happy for you that you are sticking to this! And from the looks of it you are seriously creating some great recipes, making it sound easy!
Truth be told… It’s not so easy and we’re relaxing it a little bit… Stil eating really healthy but letting in some oats and quinoa and such… Much better!!
