Cauliflower soup is a great way to use up that head of cauliflower sitting in the back of your fridge. It’s light, and mild, and goes great with some crunchy garlic bread.
This is one of those mild soups perfect for younger kids, a light meal for adults, or a nourishing soup for somebody under the weather. It also makes a great starter.

How Can I Make The Flavor Stronger?
If this soup is too mild for you, your best bet is to add more spices or use a bouillon cube. I don’t generally use them, but if you don’t have a problem with them, it’s a good option.
Can I Make This Soup Ahead?
You can! See the storage notes below. You can apply the same timing to making this soup ahead.
How Do I Adjust The Thickness Of Cauliflower Soup?
Your best bet to get the thickness you like is to add the milk slowly. Add less for a thicker soup or more for a thinner soup.
Can This Cauliflower Soup Be Made Vegan Or Dairy-Free?
Yes! If you use vegetable broth and plant-based milk, it will naturally be both.
Can I Add Other Vegetables To This Cauliflower Soup?
You can! Either cook them until soft and blend them into the soup, or make the soup according to the recipe directions and then add vegetables after blending and heat them at a simmer in the soup.

Can I Make Cauliflower Soup In A Slow Cooker?
You can, but you’ll need to sauté the vegetables in a skillet first. Then cook everything together (except the milk) in a slow cooker for about 3 hours on low, or 1-2 hours on high. You only need to cook it until the cauliflower is soft and cooked through. Then blend everything in the crock with the milk and serve.
Can I Make Cauliflower Soup In An Instant Pot?
You can! Sauté the veggies on the sauté setting. Then add everything else (except the milk) in and cook on high pressure for about 10-15 minutes, or until the cauliflower is soft and cooked through. Then add the milk and blend.
What Can I Serve With Cauliflower Soup?
Here are some ideas for what you can serve with this mild and tasty soup:
- Crusty bread
- Garlic bread
- Grilled cheese sandwiches
- Caesar salad
- Roasted vegetables
- Mixed greens salad
- Quinoa salad
- Roasted chicken
- Croutons
- Parmesan crisps
- Crackers
- Bruschetta
- Stuffed mushrooms
- Pita chips
- Baked potato

About The Ingredients
Cauliflower – Just look for a medium to large head of cauliflower. An average-sized one. You don’t have to have a specific amount here.
Red onion – You can use yellow onion in a pinch.
Garlic – Don’t be shy with the fresh garlic. Look for the biggest cloves on the bulb.
Celery – Here again, don’t worry about the size of the celery bunch. You’ll be measuring it when it’s chopped anyway.
Broth – This can be vegetable broth or chicken broth. Whichever you prefer to use. I find that chicken broth gives this a better overall flavor, but veggie broth is fine too. Either works.
Unsweetened oat milk – Or any type of milk you prefer.
Extra virgin olive oil – Or any light-flavored oil you prefer to use.
Ground black pepper – Or try white pepper if you prefer. Either will work fine here.
Dried thyme
Ground rosemary
Paprika – You can use regular or smoked if you like a smokier flavor.
Ground coriander
Garlic powder – Or garlic granules.
Onion powder – Or onion granules.
Salt – Add to taste once the soup is finished.
Fresh parsley or chives – For garnish. (Optional)
How To Make Cauliflower Soup

Gather and measure all your ingredients.

Put the olive oil into a large soup pot and warm it. Then add the onion and celery to the oil and sauté until the onion is translucent and even slightly golden brown.

In the last minute of cooking, add the garlic. Do not cook this for longer than 1 minute. Stir constantly.


Add in all the spices and stir well to combine.


Add the cauliflower and broth to the pot and stir well. Cover with a lid, bring to a boil, reduce to a simmer, and cook for 20 minutes or until the cauliflower is soft and cooked through.



With an immersion blender, blend everything directly in the pot. Then blend in the milk at the end. You should have a nice, smooth soup texture.

Season with salt to your liking and serve.
Storage
Store any leftovers in an airtight container and store them in the fridge. If you use chicken broth, it will last for up to three days. If you use vegetable broth, it will last up to five days.
Freezing
This will freeze well if packed will, for up to 4 months.
Reheating
Reheat in a pot or in a microwave.

Looks lovely! Question for you though – why garlic powder and onion powder – why not fresh onion and fresh garlic?
Jo – You can use those if you like. I just find it easier to use the powders. But you can certainly substitute!
sounds so good
Trude – Hope you enjoy it!
OMGosh! I had to laugh b/c I just bought a head of cauliflower & wondered what I could do different w/ it. Great timing. Thank you, Sherri
Sherri – Glad I could help! 🙂
Think this one would do well frozen?
Sarah – I don’t see why not, though it might be a slight bit more watery when defrosted. But it should freeze pretty well.
Think this one would do well frozen?
This really made me laugh. I can’t imagine you, Tiffany, coming home with something and not knowing what to do with it! That’s my world – every day. At least it was before I found this wonderfully helpful site. ‘Herbs de provence’ – something I find in a jar?
Thanks. And thanks, too, Tiffany, for your admirable honesty. I’m still shaking my head, picturing you with my delimma. I don’t feel quite so bad now, knowing that even you experience this on occasion. See how much you help people? They don’t pay you enough :).
Linda
Linda – Awwwe, thanks! Really, I don’t get paid at all. But I love doing this, so that’s payment enough! At least I earn enough to keep the blog going. That’s something! Glad you can use the recipe!
I love cauliflower. To me it’s almost like tofu and takes on all of the other flavours of the dish. The soup looks delicious
SMC – Yes! It really does!
This looks delicious! My go-to for cauliflower is to boil it (takes a while), mash it and use it as a mashed potato substitute. (Something I learned one of the three times I watched The Biggest Loser.)
Melanie – Yes!! I tried that eons ago when I did the South Beach Diet. Good stuff!
Glad you both enjoyed it! 🙂
I was just wondering, herbs de provence. If I can’t find it is there something I can substitute for it or would it be terrible without it if I left it out?? Thanks
You can try leaving it out, but you may want to add more of the other spices.
This soup is soooo good! I left out the herbs de provence and the parsley (didn’t have that on hand and reeeeally wanted to try this recipe) it is amazing!! I also left a few cauliflower “chunks” in as well. I felt like it was little more hearty for me. Thank you so much for this recipe! I LOVE IT!!
JB – I’m so glad you enjoyed it! 🙂
This is fantastic! The ingredients are so simple yet make such a delicious, healthy, EASY, low-calorie meal! and due to a low ‘student budget’ it’s a perfect meal for me that doesn’t break the bank. I was all out of herbs de provence so I just used mixed herbs instead and I used fresh garlic. It’s definitely one for my newly developing recipe book. I really think what you do is great – you are really helping me to turn my life around, I’ve always wanted to ‘eat clean’ (although I didn’t know that’s what it was called) and I certainly didn’t think there would be this much help, support and knowledge available – when I found this website I was over the moon! thanks again! x
Sophie – My pleasure! So glad you enjoyed it! 🙂
I made this soup the other day and it was good, but waaaay too many spices. I think next time I’ll only use one Tablespoon of each of them. Thanks for the recipe!
Kara – I do tend to enjoy stronger spices…
This is a fabulous recipe, thanks for sharing! Left the oil out and it’s HCG friendly too. I added more spices — Celery salt and paprika work really well with the soup too. I also added a red pepper in for a little more flavor and instead of chicken broth, I substituted bone broth (chicken) as it doesn’t have any sugar or oil in it (HCG friendly). It was so delicious – my fiancee loved it too!!
Paige – Glad you enjoyed it! 🙂
