Low-carb cauliflower hummus topped with toasted sesame seeds, served with lemon wedges and celery sticks

It’s another low-carb recipe using the magic that is cauliflower! I’m sure you’ve noticed that I don’t follow a low-carb diet (potato in your noodles, anyone?), but I do love to experiment with all kinds of recipes, and using cauliflower to create a low-carb version of an old favourite is something I’ve done several times before – cauliflower tabbouleh, cauliflower tortillas, cauliflower risotto… to name but a few. This low-carb cauliflower hummus is another amazing, easy way to reduce your carbs, and sneak an extra veggie into your diet while you’re at it.

Just a quick disclaimer, before I get stuck into the recipe: I’m not for one second saying that carbs (especially protein-rich carbs like chickpeas) are bad, or that we should all avoid them completely – I’m a great believer in ‘everything in moderation’ (even halloumi pie). But lots of people do follow low-carb diets for all sorts of reasons, and this recipe is for them. It’s also for people who just really flippin’ love roasted cauliflower, and couldn’t give a monkey’s about carbs.

(Just in case you do care: this recipe contains around 12g of carbs per serving, compared to around 35g in the equivalent chickpea recipe. It also has about half the calories!)

The recipe is basically a simple homemade hummus recipe, but using roasted cauliflower instead of chickpeas. Weirdly, I never used to like cauliflower – it was one of only two veg that I would say I actively disliked, the other being peas, which I also kind of like now (is this what being an adult feels like?). But then I tried cauliflower roasted, and my opinion was immediately changed. When you roast a cauliflower, it gets such an amazing flavour – the little flowery bits get golden and crispy, and totally bring it to life.

And if you blitz up some of that roasted cauliflower with a drizzle of tahini, some fresh garlic and a squeeze of lemon juice… you’ve got a really amazing low-carb cauliflower hummus. If you’re feeling fancy, I would definitely recommend topping it with a drizzle of extra virgin olive oil and a few toasted sesame seeds for an even more amazing flavour!

Now, I’m not trying to fool anyone here – this doesn’t taste like real hummus. Nobody is going to be amazed when you tell them it’s made out of cauliflower. The texture isn’t too dissimilar from regular hummus, but (surprise surprise) it definitely tastes like roasted cauliflower. But if you’re a fan, and you want a fun low-carb snack idea, this cauliflower hummus is the recipe for you!

Of course, you can serve your cauliflower hummus with some crackers or breadsticks if you like, but in keeping with the whole low-carb thing, I used some celery sticks. Crackers would have been better (I’m adding celery to the list of vegetables I don’t like…).

  • 1 large head cauliflower (~ 1 kg / ~ 2 lbs)
  • 2 tbsp oil
  • Salt
  • Black pepper
  • 1 small clove garlic, peeled
  • 1 tbsp tahini
  • Squeeze of lemon juice
  • To serve: 1 tbsp toasted sesame seeds, 1 tbsp extra virgin olive oil (both optional, but highly recommended!)


  • Remove the leaves from the cauliflower, and cut into chunks. Toss in a little oil, season with salt and pepper, and spread it out in a single layer on a baking tray (use two trays if needed). Roast at 190°C (Gas Mark 5 / 375°F) for around 30-40 minutes, until the cauliflower is soft, with crispy, golden brown edges. Set aside to cool.
  • Add the cooled roasted cauliflower to a food processor, along with the garlic, tahini, and a squeeze of lemon juice. Blitz very thoroughly, scraping down the sides, until fairly smooth. You can add more seasoning, lemon juice, etc. if needed. Store in the fridge and serve lightly chilled.


To make the toasted sesame seeds, add a spoonful of sesame seeds to a dry frying pan, and cook over a medium-high heat for a couple of minutes, stirring regularly, until they’re golden brown. Watch them carefully, as once they start to turn they’ll go quickly!

  1. This didn’t taste like hummus, I had to modify it a bit. I added 2x as much tahini, 1-2 Tbsp lemon juice (depending how large the cauliflower), water to make it creamier, and hummus wouldn’t be hummus without cumin, paprika and olive oil. So about 1/2-1 tsp of each spice.3 stars

  2. I have made something very similar using a raw courgette instead of roasted cauliflower (which I’m not convinced by); I prefer it to baba ganoush, and it makes a fabulous salad dressing. Hmmm, must make it again soon….

  3. Yum! I love cauliflower and peas too! I never thought to try cauliflower as a hummus but why not! I will be making this for my next get together. Thanks!
