This creamy and comforting Cauliflower and Broccoli soup is veggie packed and an easy way to get more vegetables into your family's diet. Ready in under 30 minutes, it's warming and easy to adapt with different cheeses and toppings, so there is something for everyone.
We love 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.
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.

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. 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.
- 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
More ingredient substitutions and variations can be found in the recipe card.
Step by Step
One: Heat the oil in a large soup pan and add the onion and garlic. Cook on a low heat for 3-4 minutes until softened.
Two: Add the chopped broccoli and cauliflower and season.
Three: Add the stock and stir well. Bring to the boil and simmer for 15 minutes.
Four: Blend the soup and then stir in the milk, cream and cheese.
What to Serve it With
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. You could also serve it with a chicken or turkey sandwich for a bit of a protein boost.
You can also keep things classic and just serve this soup with a French baguette that has been warmed up in the oven, or some croutons on top. Or both. You could even go all out and make your own bread. Why not try our Garlic and Rosemary Focaccia?
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.
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.
Extra Tips
- You can add cheddar, stilton or Parmesan on top of this soup.
- 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.
Frequently Asked Questions
Both broccoli and cauliflower are rich in Vitamin-C, Vitamin-K, fibre and folate. Broccoli also contains Vitamin-A and cauliflower is rich in B vitamins and antioxidants, and is known to help with eye health.
This soup is also really low in calories and fat too. It doesn't taste healthy though, and actually tastes far more indulgent then it actually is.
We recommend using a strong flavour cheese in this, as you won't need to use a lot of it. You could swap the mature cheddar for stilton and it would be like a broccoli and stilton soup, but with cauliflower mixed into it.
Yes, you can use frozen vegetables for this recipe, however that 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.
When vegetables are cooking in water, the water soluble vitamins from the vegetables will escape out into the water. Normally, the water is then poured away when the veg is ready to eat. By using the cooking water in the soup (rather than just stock), all the vitamins lost from the cooking process will be retained.
Yes, this can be done on the slow cooker instead and it makes it an even easier meal. Simply put all the ingredients in your slow cooker and cook on high for 3 hours or low for 6 hours.

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.
