Roasted Cauliflower with Citrus Tahini Sauce


I have moaned more than once about my friend, Colette, being vegetarian as I find it difficult to come up with different and interesting vegetarian dishes for her.  Colette either gets one of the few tried and true recipes or some strange concoction that shouldn’t be repeated.  As a result, when I spy a vegetarian dish that looks interesting and tasty, I get a little excited.  Such was the case when I spied this recipe in Suzanne Husseini’s  Modern Flavours of Arabia.

I showed Colette the recipe and it got the thumbs down.  To my dismay, Maus was on Colette’s side.  Not to be deterred, I decided to make it anyway.  Let me tell you, it was fantastic.  Maus, the fussy one, ate every mouthful and then apologised for being a doubting Thomas and … the next time Colette visited, she also apologised.  The day before, she had been to a restaurant where they had just one vegetarian dish on the menu – roasted cauliflower – so she ordered it … and loved it.

This dish is very tasty.  The roasted cauliflower is sweet and delicious.  The richness of the tahini is balanced by the citrus in the sauce.  It is just perfect.  Give it a go.

As there were only two of us, I halved the recipe and it was just the right amount.  These quantities would serve 4, with a side salad.


  • 1 cauliflower
  • about ¼ cup of olive oil
  • salt
  • juice of 2 lemons
  • zest and juice of ½ an orange (I used a bit more)
  • 1 cup water
  • ¾ cup tahini
  • 3 tbs* olive oil, extra
  • 2 cloves garlic, crushed
  • 2 medium onions, thinly sliced
  • ½ cup toasted pine nuts, to garnish
  • ¼ cup chopped pistachios, to garnish

*These are 15 mil tablespoons


  1. Preheat the oven to 200°C.
  2. Slice the cauliflower (core included) into thick slices.  Try to keep the slices whole but don’t get too worried if it falls apart a bit.
  3. Line a baking tray with baking paper.  Coat the cauliflower with olive oil, season with salt and then spread it out on the tray.
  4. Roast the cauliflower until it is golden and crisp and cooked through.  Turn it over half way through.  It should take about 20 minutes.  Try not to break the cauliflower when turning it.
  5. In the meantime, mix together the lemon juice, orange juice and zest, water and tahini.  Set aside.
  6. In a frying pan, heat 3 tablespoons of olive oil and gently sauté the onions and garlic until soft.
  7. Pour the tahini sauce over the cooked onions and bring to a simmer.  Cook until the sauce thickens slightly. Taste, and adjust seasoning, if needed.
  8. Serve about one quarter of cauliflower to each person.  Drizzle the tahini sauce over the cauliflower and garnish with the toasted nuts and additional orange zest.

  1. Hi, we love roasted cauliflower and love tahini sauce. Might try cauliflower lightly steamed and finished on the grill during summer when I am loath to turn on the oven. Great photo Glenda, makes we want to sit and eat. Is that salad from your garden?

  2. For a log time, I avoided cauliflower. I just didn’t care for it when steamed or served raw and those are about the only way it was ever prepared. Now, though, I thoroughly enjoy it roasted. Adding this citrus-y sauce could only make it better. I gotta try this!

  3. Although I am an omnivore, I LOVE veges, eat them copiously, by choice, and adore cauliflower any way… so YUM 🙂 I’ve been wanting to try baked cauliflower but sadly, it will be on a night when I’m eating solo, as the G.O. won’t even consider it.

      • For me yes, but for the G.O… nup, he would just look at me like I had lost my mind, and then eat the steak, only… I have an enduring memory of a lunch we attended once and the poor hostess who the G.O. isn’t fond of anyway, served a huge piece of boiled cauli per plate which after clearing his otherwise, the G.O. conspicously left… I cannot tempt him, not anyway anyhow to eat it 😉

  4. Ah, if people would just give things a try. Everything about this looks fabulous & now you’ve got me thinking that I could even sneak it past my non-cauliflower eating husband. I just got him to try a butternut squash soup that he admitted to liking so maybe just one new idea per week/month?

  5. Colette is always very grateful for ANY food you are prepared to cook her Glenda. I found the idea of a large ‘steak’ of cauliflower a little odd. In my naivety I thought it might be a bit bland. I am very much looking forward to testing it out and always happy to be proven wrong on these matters!

  6. Glenda, this looks and sounds delicious! You are a very accommodating cook! I would just go ahead and make it : )
