How To Thicken Cauliflower Soup?

The best way to thicken cauliflower soup is by adding a starch such as flour or cornstarch. Start by making a roux with butter and flour, then gradually whisk in the stock from the soup until it’s thickened to your desired consistency. Alternatively, blend some of the cooked vegetables from the soup in a food processor and add back into the pot.

Cauliflower soup is a delicious and nutritious meal, but sometimes it can be too thin.

If you’re looking for ways to thicken your cauliflower soup without compromising flavor, here are ten easy methods that will do the trick:

1. Add cheese

Munster cheese

Cheese? In soup?

You betcha!

Adding cheese to your cauliflower soup is like adding a sprinkle of magic to make your meal even more delicious.

Not only does it add some extra flavor, but it also thickens up the soup so you won’t have to worry about thin and watery broth.

So don’t be afraid to break out your inner mad scientist and experiment with different types of cheese for an unforgettable taste sensation.

2. Use cream


If you want a creamier soup that can stand up on its own, then use cream instead of milk or water as the base for your dish.

It’s like having a much thicker blank canvas which will allow all the flavors in your dish really shine through – especially if you’ve added lots of flavorful ingredients like potatoes, onions and garlic!

And thanks to this upgrade in ingredients, you’ll get a lovely creamy texture without worrying about being left with a too-thin soup at the end.

3. Blend some of the cauliflower

Taking some of the cooked cauliflower and blending it into the dish directly is another great way to thicken up your cauliflower soup without compromising on flavor or nutritional value.

Or why not get creative by pureeing half of the cooked veggies until smooth and combining them back with chunks for variety?

That would give every spoonful something interesting going on — smoothness combined with surface textures — perfect for getting those tastebuds excited!

4. Use cornstarch


Cornstarch is like the sweetheart of thickening agents – it’s quick, easy, and always delivers stellar results.

When added to a thin cauliflower soup, it will act like an invisible chef who stirs and turns up the heat on your concoction to create that perfectly creamy consistency you’re looking for.

Plus, cornstarch won’t alter the flavor at all so you can enjoy every wonderfully-wholesome spoonful without having to worry about compromising taste or texture.

5. Use arrowroot powder

Arrowroot Flour

This powdery superhero can thicken food faster than a speeding bullet and make your thin cauliflower soup seem practically perfect in every way with its velvety texture and impeccable smoothness.

Arrowroot powder has been used since ancient times as both a medicinal remedy and a cooking aid thanks to its natural healing properties and high-performance thickening power – so you know it’ll have no problem making your soup ultra-thick in record time!

6. Add pureed potatoes

White Potatoes

Potatoes aren’t just masters at being mashed – they are absolute experts when it comes to stretching soups from super thin to seriously sturdy!

Pureeing one potato (or two if needed) will give your too-thin cauliflower soup much more body without changing any of its soothing flavors or tantalizing textures, so any picky eaters out there won’t send this meal right back into their bowl (unless they request seconds!).

7. Add pureed white beans

If your cauliflower soup is looking a bit too thin for your liking, never fear!

Adding a few pureed white beans to the mix is like giving it a hug without all that awkwardness.

The white beans add heft and body to the soup, helping it turn into a robust dish that will fill you up and leave you with a happy smile on your face.

It’s like having health insurance for your tummy – just in case something goes wrong, you always know you’re covered!

8. Use a roux


Roux is French for ‘the magical mixture’ (okay I made that up) but really, this combination of butter and flour can take any soupy situation from hot mess to haute cuisine status in no time.

Simply make sure that the roux has reached an amber color before adding it to the cauliflower soup; then sit back, relax and admire how quickly this simple trick can give your soup more body without sacrificing taste.

9. Use evaporated milk

evaporated milk

Evaporated milk packs quite the flavorful punch when added to thickening liquids like cauliflower soup; plus its mild flavor makes it perfect for those who want their meal to shine through with its natural taste rather than masking itself beneath strong spices or herbs.

To use evaporated milk as a thickener all you need is just one cup per four servings of soup – voila!

You have yourself an irresistibly creamy bowl of goodness (without any fuss).

10. Use coconut milk

Coconut milk

Adding coconut milk to your cauliflower soup is like hitting the jackpot – it’s both healthy and delicious.

Not only does the milk make your soup extra creamy, but its sweetness gives it that something special that takes it from ‘good’ to ‘great.’

Plus, it’s a great way to get some extra nutrients into your meal without packing in too many calories.

It may be an unconventional choice, but with this ingredient, you can’t go wrong!

11. Use mashed avocado

mashed avocado

Mashed avocado might sound odd as an add-in for soup, but trust me when I say it truly elevates the dish (and makes it even healthier!).

When combined with your cauliflower soup base, mashed avocado gives off a nice velvety texture while also adding some essential fatty acids and vitamins K and B6 into the mix.

For best results, spoon dollops of creamy mashed avocado over each bowl of piping hot cauliflower soup!

12. Add a tablespoon of tahini


Tahini is another versatile favorite when adding richness and creaminess to dishes such as soups or porridge – especially if you want to cut down on saturated fats (but remain full).

One tablespoon of tahini adds not just beautiful flavor complexity but also all nine essential amino acids – hello nutritional powerhouse in one spoonful!

A silky garnish made from tahini will perfectly complement a steaming bowl of cauliflower soup…enjoy!

13. Use a slurry of flour and water

Brown Rice Flour

Forgot to thicken your soup as it was cooking?

No worries, a slurry of flour and water can swoop in and save the day.

Just mix these two simple ingredients together until they form a thick paste and then stir it into the soup while simmering on low heat. We like to think of this method as getting an ace up your sleeve when you need it most.

14. Add some breadcrumbs


Breadcrumbs are not just for sprinkling over casseroles – they make a great addition to cauli-soups (if we may coin a term).

Toss some breadcrumbs or even croutons into the mix before serving for added texture and flavor that will take your soup from meh to mmmmmmm in one simple step!

15. Use a spoonful of nut butter (such as almond or cashew)

Peanut Butter

Who knew nuts could be so versatile? You can even use them to thicken soups! A spoonful of nut butter, such as almond or cashew, is all you need for perfectly creamy cauliflower soup without having to sacrifice any nutrition points.

It’s like hitting two birds with one stone: deliciousness meets healthiness, no matter which combination of flavors you choose!
