You’d be forgiven if you think we’re obsessed with broccoli and cauliflower.
Not only do we now have broccoli and cauliflower soup, we also have a broccoli and cauliflower salad, and a roasted Mediterranean broccoli and cauliflower bake. That’s a lot of broccoli and cauliflower. And you know why?
Because it rocks. It’s that simple.
It’s tasty, it’s filling, it’s nutrient dense and it’s cheap.
Superfoods get shouted about all the time. Like a z-list celebrity they rise and fall from grace; sometimes you can get hold of them, sometimes you can’t. Prices tend to stay high, however.
What makes them so super, anyway?
Broccoli and cauliflower don’t cause anywhere near the excitement the latest grain or berry that grows only in moonlight on the mysterious plains near the magical waterfall does, but they should.
Both are cruciferous vegetables and are incredibly high in nutrients and vitamins. But we’ve talked about this before. You can find all the veggie goodness details and research right here and here.
What I’m more interested in today is the cooking method.

Boiling? Roasting? Steaming? Frying?
Although all forms of cooking result in some loss of vitamins within vegetables, it is generally regarded that steaming is one of the best ways to cook veg, and boiling is not.
That’s mostly because the water soluble vitamins in veg will leak out into the water when boiled. Then they’ll be poured down the plughole when the veg is ready.
But not if you make soup! Those lovely vitamins will be retained and eaten – by you. Pretty awesome, huh?
So, make broccoli and cauliflower soup and enjoy the vitamins and nutrients at their best.
How to eat broccoli and cauliflower soup
Our filling and healthy broccoli cauliflower soup is versatile and can be eaten on different occasions.
You can have it as a wholesome meal with a side of whole-grain toast and green salad. It can also be an appetizer, which will stop you from eating more for the main course.
Cheddar cheese will make this broccoli and cauliflower soup extra creamy and flavourful. You can also use some cream as an alternative or just keep it vegan with nutritional yeast.



Broccoli – always a great idea
Broccoli is one of the foremost vegetables to come to mind when thinking about green vegetables rich in nutrients.
This superfood contains many vitamins and minerals vital to our health – vitamins A (in the form of carotenoids), B (especially folate), C, E, K, and phosphorus, calcium, iron, zinc, magnesium, potassium, and selenium.
100 grams of broccoli provides 34 calories, 2.8 g of protein, 2.6 g of dietary fiber, and has 89% water content.
The high fiber and water content reduce appetite and increase overall satiety. So this broccoli and cauliflower soup can help you to fill up and support your weight loss goals.
In addition to that, the high fiber content in broccoli draws helps to slow down absorption of food which can contribute to improved cholesterol and blood sugar readings. One review showed improved insulin resistance in type 2 diabetes patients who consumed broccoli sprouts daily for a month.
Perks of being a cauliflower
Cauliflower is also powered by vitamins – B (folate), C, K, and minerals – phosphorus, biotin, potassium, and magnesium.
100 grams of cauliflower provides 25 calories, 1.9 g of protein, 2 g of dietary fiber, and has 92% water content.
Just like broccoli, cauliflower is high in fiber and water content and promotes fullness. The fiber also supports digestive health by improving bowel functions.
There are many interesting ways to serve cauliflower – roasted or steamed as a side dish, fried, baked with cheese, as the main ingredient in a curry.

Broccoli-cauliflower duo for weight loss
In this broccoli and cauliflower soup recipe, two powerful vegetables come together to help you on your weight loss journey (more vegetarian weight loss soups this way!). They both offer a nutrient-rich profile with enough fiber and water to promote satiety.
It’s very important to make certain that all the calories you consume have nutritional value, especially while losing weight. This healthy broccoli and cauliflower soup recipe takes care of that.
More than 50 studies concluded that increasing fiber intake by 14 g a day over about four months provided a 10% decrease in daily caloric intake and body weight loss of 2 kg.
This creamy broccoli and cauliflower soup can slow down your digestion thus reducing calorie intake throughout the day (it’s one of our favorite filling low calorie soups for a reason!).

What our readers are saying
Just what I wanted – quick, easy and nutritious! Made it with mainly broccoli as only had a tiny bit of cauliflower left. Roasted a tin of chickpeas and threw them in at the end with the cheese instead of crutons. Delicious!

Yummmmmm currently spooning a bowl of this deliciousness into my face right now!!! I didn’t have any basil so left that out, used dry thyme instead of fresh, used a shake of celery salt, and 2 tbsp of nutritional yeast in place of the cheddar. Thank you for a delish recipe! Going into the staples ❤️
Lisa ⭐⭐⭐⭐⭐
Great soup! Added Parmesan instead of Cheddar as I like it more salty. You have earned another devoted follower!

Just finished making this soup. Tastes wonderful and has a lovely mouth feel. No cheese added as I am watching my cholestrol. Added a medium potato and some whit pepper along with the other ingredients. This soup is thick and very tasty. We all love it. Thank you for this great recipe. It is very cold in Melbourne Australia at the moment so soup is a regular in our home.
Thanks too, Chris, really glad you enjoyed it! Yep agreed, it’s perfect for those winter evenings. Thanks for writing!
Really Yummy! I subbed cottage cheese for cheddar cheese for some added protein and tripled the garlic.
Interesting idea to use cottage cheese! Glad it turned out tasty 🙂
The soup is very easy to make, but a tad salty due to the Cheddar cheese. Will make again with crème fresh and a little less Dijon mustard!
Oh great idea, let us know how it goes!! 🙂
Quite tasty. I kept the cheddar cheese on the side for those that wanted it, and added only water to the soup mixture (with spices, and oregano).
Really glad you liked the soup, Barry!!
Thanks Barry, glad you enjoyed it!
I had a lot of broccoli, so I didn’t get to add cauliflower, however, I found this soup very delicious. I love the dijon and I had fresh basil…I left the thyme out and used shallot because I wanted to use what I had. I enjoyed it with a Jackfruit/chickpea vegan take on tuna salad for a great soup and salad supper. Oh, and I added a little vegan cheddar in the bowl. Yum!
Wonderful! Really happy our recipe served as a tasty base! 🙂
