Ingredients you will need

Ingredients for whole roasted cauliflower
  • Cauliflower. I’d recommend using a small or a medium head to make sure it cooks all the way through.
  • Olive oil. I find that olive oil achieves the best earthy flavour.
  • Tamari. You can use soy sauce if not avoiding gluten, or coconut aminos for a soy-free version.
  • Fresh garlic. This will make your kitchen smell amazing!
  • Garlic powder.
  • Garam masala.
  • Cumin.
  • Dried basil.
  • Red chilli. This will add a slight hint of spice, but you can leave it out if you want.
  • Lemon juice.
  • Fresh thyme to sprinkle on top.

How to roast cauliflower

Firstly, preheat the oven to 180 degrees C (350 F) and line a baking tray with a sheet of parchment paper.

Prepare the cauliflower by trimming the leaves and the base of the stalk of the cauliflower, but make sure not to accidentally trim away any of the florets.

Next, mix together the the olive oil, tamari, garlic, garlic powder, garam masala, cumin, dried basil, chilli pepper, and lemon juice.

In order to achieve more flavour, turn the cauliflower upside down and pour in around 1/4 of the sauce, shaking it a few times to distribute it throughout the florets. Place it on the baking tray and brush the rest of the sauce all over the cauliflower. You can also use your hands to do this.

Sprinkle some fresh thyme on top and place in the oven and roast for around 50 minutes, until golden brown on the outside and tender on the inside (you can test for readiness using a toothpick). After around 45 minutes, keep a close eye on it to make sure that it doesn’t start to burn.

Lemon tahini sauce

You can, of course, serve this whole roasted cauliflower with any sauce of your choice. But I think that this lemon tahini sauce goes so well with the rest of the flavours. Its light, tangy and fresh flavour perfectly contrasts the depth of the cauliflower.

You need just a few ingredients: plant based milk, maple syrup, balsamic vinegar, tahini, lemon juice and salt. Simply whisk them together when the cauliflower is almost ready.

Tips and tricks for the best whole roasted cauliflower

  • It’s important to use a small or a medium cauliflower, as one that is too big may burn on the outside, but still end up being undercooked.
  • Make sure to use as much of the sauce as you can to maximise the flavour.
  • Keep in mind that baking times can vary between ovens.
  • You can add any other spices or dry herbs of your choice depending on your preferences.
