This creamy and comforting Cauliflower and Broccoli Soup recipe is veggie packed and an easy way to get more vegetables into your family's diet. Ready in under 30 minute with just a few ingredients (you can even use frozen veg too), it's warming and easy to adapt with different cheeses and toppings, so there is something for everyone.
You can't beat a hearty and veggie packed soup in winter time. Sandwiches don't quite cut it, and as long as there is bread involved then the kids are happy.
Believe it or not, this bright green broccoli and cauliflower soup is a favourite with kids. It's so creamy, and a great way to get some extra vegetables into them.
There are plenty of vegetables in this soup, but it really doesn't taste like it because of the creaminess. It tastes far more indulgent than it actually is and it is only 306 calories per bowl.

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Broccoli
- Cauliflower
- Onion - You could swap this for shallots if you prefer, and this would give the soup a slightly sweeter taste.
- Garlic - To save yourself some time, use some of that lazy ready chopped garlic in a jar.
- Cheese - We used a mature cheddar cheese. It has a really strong flavour, so you don't need to use as much of it.
- Milk - You can used skimmed, semi-skimmed or whole milk.
- Cream - We used single cream and it just gives the soup a little something extra. You could leave it out if you wanted to, or use reduced fat creme fraiche to make it lighter.
- Stock - Try to use the best quality stock you can buy. If you are making this for young children, then use a low salt stock.
- Salt and Pepper - Generously season.

What To Serve With Cauliflower and Broccoli Soup
This soup is really low in calories, so we usually have it as a starter or serve it with a sandwich. A grilled cheese sandwich is perfect with these and total comfort food. Or a cheesy bagel that is melted under the grill or in the air fryer.
You can also keep things classic and just serve this soup with a French baguette that has been warmed up in the oven, or try making your own bread with our Slow Cooker Bread or Easy White Bread Loaf.
You could also add some crispy bacon on top. Make our Air Fryer Bacon, chop it up and then sprinkle on top.
Homemade Croutons
Soup and bread is such a classic combination. But why not take the humble slice of bread and butter up a gear and make your own crunchy croutons? Not just any croutons, but cheesy, herby croutons.
They are so easy to make, and a great way to use up bread that is going a little stale. The perfect addition to cauliflower broccoli soup.
Just take a couple of slices of bread and cut into 1 inch cubes and scatter on a baking tray. Drizzle with olive oil and sprinkle with Parmesan (or grated cheddar) and sprinkle with dried oregano.
Put them in a preheated oven at 180°C/350°F/Gas 4 for around 8 minutes.
Storage
This can be kept in an airtight container in the fridge 3-4 days. Reheat on the hob (stove top) until cooked through, about 5 minutes.
If you want to freeze the soup, put it in an airtight container, leaving a gap of about 1cm (0.5 inch). This will keep in the freezer for 2-3 months. Defrost in the fridge over night before reheating.
Tips To Make The BEST Cauliflower and Broccoli Soup
- You can add Cheddar, Stilton or Parmesan on top of this soup to make it extra creamy.
- Use a really good quality stock cube, as you will taste the difference. If you are making this for kids, then use a low sodium stock cube.
- To blend, try to use an immersion blender. If you are going to use a jug blender, then allow the cauli broccoli soup to cool completely before blending. You may need to do it in batches.
- Taste the soup before serving and then add more salt if needed.

Can you use frozen Cauliflower and Broccoli
Dannii says
Yes, you can use frozen vegetables for this recipe and I have written about that in the FAQ section of the recipe. However, frozen veg tends to give you a much more watery soup. If you are using frozen vegetables, then you will need to reduce the amount of stock you have used.
Denise Mattison says
i made this and it has far too much broccoli in it. it went really green and didn't taste nice at all. next time i try i will at try half the broccoli.
Dannii says
It's cauliflower and broccoli soup, so it will have a fair amount of broccoli in it. It is equal amounts of broccoli to cauliflower. As the photos show, it is a green colour.
