Warm up with this comforting quick and easy Broccoli and Cauliflower Soup recipe. You’ll have a hug in a bowl in about 20 minutes, ready for a healthy lunch or a no-fuss vegetarian family meal. Try the trick of frozen veg for an ultra simplified version!
When the weather turns colder it can be tricky to come up with healthy lunch recipes. Hello Broccoli and Cauliflower Soup!
I don’t know about you but when I’m cold the thought of a salad for lunch makes me shudder a bit.
Soup, my friends, is a healthy hug in a bowl that we all need at lunchtime or even for a lazy dinner.
This recipe is really quick to make (even better if you batch cook and freeze). Serve it with crusty bread and extra cheese and you are good to go.
We can simplify this even more by using all frozen veg (the best hack because – no chopping!) and if you’d rather make it in the slow cooker instead, the instructions are below.
Why you’ll love this Broccoli and Cauliflower Soup recipe
⭐️ So tasty, quick and hardly any effort
⭐️ No prep – just throw it all in
⭐️ Delicious leftovers – cook once, eat twice!
How I came up with this soup recipe
I know making homemade soup can be a bit daunting, but once you’ve tried one or two recipes, you’ll see that they’re actually really simple!
Just a bit of chopping and then it’s all in the pan until it’s time to blend.
Of course, there’s the slow cooker method too if you’d prefer to do the prep earlier in the day (I have to say, this is so good when you know you’re going to be pushed for time when lunch or dinner comes around.)
I wanted to create a soup recipe that involved loads of goodness and flavour, but also didn’t take too much chopping or peeling.
Broccoli and Cauliflower tick those boxes! Plus they’re great value for money, easy to get hold of, and quite often they’re the veggies we have in the fridge already, so we can use up what’s left.
They taste amazing together AND we can even buy them as frozen ingredients, so all we have to do is put them in the pan (we can also use frozen onion and garlic for prep that takes seconds).

Leftovers
In the fridge Broccoli and Cauliflower Soup can be cooked and kept in an airtight container for around 3-4 days in the fridge.
This is a perfect make-ahead or batch cook recipe. It just needs reheating on the hob until warmed through before serving.
In the freezer You can also freeze the soup in an airtight container for 2-3 months. You should defrost it overnight in the fridge and reheat thoroughly.
Top tips
How to make Broccoli and Cauliflower Soup in the slow cooker
Add the same ingredients and cook on HIGH for 3-4 hours or LOW for 5-6 hours. Perfect for straight after a winter’s walk!
Stock
You can use vegetable or chicken stock in this recipe, depending on your preference. If you like a thinner soup, add slightly more, or less for a thicker heartier version. I like Marigold Boullion Powder.
Toppings
You can put any cheese you like into this soup. It would be delicious with Parmesan, Stilton or Gruyere, or a combination. It is a great way of using up leftover bits of cheese in your fridge. Croutons would also be good.
What to serve with this
You can simply enjoy this with some chunky bread on the side, but if you’d like to make it as part of a bigger meal, you could make cheese on toast, a jacket potato, or a nice sandwich like a Tuna Melt.
FAQs
Do I need a blender to make this recipe?
Honestly? Yes. I think you do. You could mash everything when it’s well cooked, but you just aren’t going to get that smooth soft soup texture we are looking for.
A hand blender is a really good buy and they start from about £15. A simple one from Amazon is a good starting buy if you fancy making soups.

I had a half bag of frozen broccoli, mostly stalks, taking up space in my freezer, so I just halved the recipe. It turned out great 😊 The only change I made was roasting my broccoli instead of boiling.Reply
I used mixed frozen cauliflower and broccoli to make the prep even quicker. Made this a few times now . Great recipie.Reply
really lovely, so pleased with how this turned out, made a lovely winter lunch for friends with some crusty bread,Reply
Absolutely fantastic a really tasty soup.Reply
Fab.. 👏👏👏👏 I parboiled the veg first and then used the soup maker to do the rest. Gorgeous consistency and flavour.Reply
So so good., easy to make and tastes delicious. Thanks for the recipe.Reply
A beautiful soup. I used frozen broccoli and cauliflower. I really enjoyed it thanx.
Can you freeze it?Reply
I loved the recipe, so tasty!! My at the time 10 month old did, I did and also my mum did! Thanks for a great recipe. I’ve since found out I’m milk and eggs intolerant 🙁 I’m going to try and use unsweetened oat milk instead of the regular milk and just leave the cheese out… I’ve not found any milk free cheese yet that tastes nice so I can’t substitute it. Hope it’ll still be nice eek! Here goes!Reply
It’s the first time I have made my own “home made soup” it was quick, very easy and tasted lovely. Full marks, many thanksReply
So pleased you enjoyed it John!
