🧾 Ingredients
This whole roasted cauliflower head is made with just a few delicious ingredients.

- The whole cauliflower head - steamed, fried, or roasted - is such a versatile ingredient to work with. It is the perfect side dish or can be used to make hearty meals and snacks.
- Extra virgin olive oil - brings the golden color out of the cauliflower and helps caramelize the cumin. It is heart-healthy and gives a deeper flavor to vegetable dishes like this one, so using a good quality Spanish or Italian olive oil is key!
- Fine sea salt 🌱 - yum! Rounds up all the roasting flavors!
Optional: Maldon flaky salt to serve the cauliflower. You can also rub some of it with olive oil before baking the cauliflower head.
See the recipe card for quantities.
🔪 Instructions
This morning detox drink involves 3 simple steps.
- Washing and preparing the cauliflower.
- Boiling in the cauliflower head.
- Roasting the cauliflower with oil.
Preheat oven to 480 ºF (250ºC).

Carefully cut the outer leaves of the cauliflower and about an inch of the hard stem.

Boil the whole head for 12 minutes in salted water until the cauliflower is fully blanched.
Hint: you can leave the head intact with its leaves. The green leaves will turn dark brown and can be great for plating the dish.

Remove the cauliflower from the heat and drain. Pat dry with a clean tablecloth.

Place the head of cauliflower on a prepared baking dish lined with parchment paper or a cast iron pan, top it with the oil, and brush it evenly.
Hint: optionally massage the cauliflower with Maldon salt. Make sure you add olive oil to the cauliflower upside down, so the center also gets some olive oil goodness.
Bake cauliflower in the mid-rack for 15-20 minutes, watching the oven after 15 minutes to ensure the top is not too burned. A dark golden brown is what we aim for!

Bake the trimmed cauliflower head in the preheated oven, and roast until it has a lovely golden brown color.

Place the entire head on a single serving plate and slice right in the middle.
Hint: if you want to add color, add chopped fresh parsley and black pepper. You can also add some zesty lemon juice on top to serve.

🍶 Substitutions
Not much to substitute for the three-ingredient recipe, but if you are curious to try other simple flavorings, I recommend you to use toasted sesame oil, which has a strong and decisive flavor that pairs wonderfully with cauliflower.
That's why we used tahini paste on our whole roasted spiced cauliflower with tahini sauce.
📖 Variations
Adding spices to the boiling water is one easy way to infuse the whole head of cauliflower with your favorite seasonings and colors into your cauliflower head.
You can add a cube of concentrated vegetable broth and spices like smoked paprika and turmeric.
Another option, if you love your garlic, is to massage the boiled head of cauliflower with garlic powder and olive oil before you bake it.
If you like to add a sour note, you can drizzle freshly squeezed lemon juice on top of the whole baked cauliflower.
🍽 Equipment
- Sharp knife and chopping board to remove the outer cauliflower leaves and inner stem.
- Baking tray - and parchment paper to put the head of cauliflower in the oven.
- Medium to large pot - to boil the cauliflower.
- Kitchen Brush - optional, to evenly coat the cauliflower with olive oil.
🥡 Storage
Store leftover cauliflower in a covered container in the fridge for up to 3 days.
You can freeze leftovers, but the cauliflower will be a little mushy when they thaw. If you absolutely need to freeze it, use leftovers to make a vegan "egg salad".
You can freeze your immune-boosting juice in an airtight container, but it doesn't stand up well to freezing for more than 3 months. It will never reach the same nutrient density as fresh juice, but you will still enjoy its health benefits.
💡 Top tip
The trick in this easy recipe to ensure you have a softer cauliflower is to boil it. Otherwise, you must use aluminum foil before turning it into the oven. Then remove the foil to get the top of the cauliflower browned.
