Are you ready to step up your vegetable game and transform a humble cauliflower into a masterpiece? If you think you don’t like cauliflower, you probably just don’t like boiled, mushy cauliflower that reminds you of a bad school dinner. But this recipe for Chimichurri Cauliflower with Tahini Sauce, we assure you, couldn’t be further from this. It is the perfect recipe for when you’re feeling lazy but have friends coming over and want to make something delicious.

The cauliflower takes on this buttery, sweet but salty crust in the oven and it is topped with a garlicky tahini yoghurt and a chimichurri-style salsa.

Cauliflower, often underrated, holds incredible potential. Its mild taste and versatile nature make it a great base for creativity and new flavours. Whilst we’ve kept the cauliflower simple here so its buttery flavour shines, we’ve paired it with two delicious sauces to level it up.

This recipe also happens to be vegetarian, so it is an even better dish to serve to all your friends together!

Oven-roasting cauliflower is also good for you: it retains more nutrients compared to boiling. Cauliflower is rich in vitamins, minerals, and fibre, making it a nutritious vegetable to include in your meals!

Frequently Asked Questions

Why is my roasted cauliflower mushy?

If you’re roasting individual cauliflower florets, overcrowding on the baking sheet is the culprit as they can steam instead of roast, leading to a mushy texture. But with this recipe, since the cauliflower is roasted whole, the main reason might be excess moisture on the cauliflower before roasting. If the cauliflower isn’t dried properly after parboiling, it can become mushy while roasting. Make sure you really allow the full 10 minutes for it to steam dry for best results.

Should my cauliflower be boiled before cooking?

When you are roasting individual florets, there is no need to parboil as they are small enough pieces that they will roast quickly. But in this case, as the cauliflower is roasted whole, we’re parboiling it to reduce cooking time. Boiling cauliflower for a few minutes before roasting can slightly reduce the overall cooking – also making it weeknight friendly! Keep in mind that boiling cauliflower should be done briefly, just until it’s slightly tender. Over-boiling can turn it mushy and bland: we parboil it for just 6-8 minutes until tender so that it spends all the time in the oven getting golden and gorgeous.

Is it possible to make this roasted cauliflower recipe vegan?

Yes – simply replace the Greek yogurt with your favourite plant-based alternative!

  • 1/4 lemon, juiced

  4. Mix together the Greek yoghurt, garlic and lemon juice to make the base.

  7. Spoon some garlicky yoghurt onto a serving plate and pop the cauliflower on top. Drizzle with tahini and chimichurri.
  8. Cut into wedges and enjoy!
