So let me explain how you can easily make entire head of cauliflower delicious. Moreover, this cauliflower recipe is much easier to make than roasted cauliflower steaks.

How to make whole roasted cauliflower

I love how easy this dinner recipe is! To prepare cauliflower, wash it and pat dry with paper towel, trim the outer leaves. That’s it. No food processor and almost no knife is needed to make this easy recipe. Maybe trim off the bottom of cauliflower, so it can sit on the baking dish.

So all you need to do is steaming a head of cauliflower, which will make it easier to absorb the spices. If you don’t have a steamer, just put a head of cauliflower upside down in a big pot with boiling water and after 5-10 minutes (depending on the size of the vegetable) remove it from the pot with tongs.

Preheat the oven. Let the cauliflower cool down just a little that you can touch it. Drizzle with olive oil and rub with spice mix. For spice rub I used dried ground garlic, cayenne pepper, smoked paprika, turmeric, cumin and lemon pepper. This spice mix will deliver beautiful taste and beautiful color of whole baked cauliflower, too.

I rubbed with the hands, but you can use kitchen gloves, if you have any scratches on your hands. By the way, when you rub it, don’t forget to gently push cauliflower florets to get the flavor in between. Put cauliflower into the baking dish. You don’t need to wrap cauliflower head in aluminium foil.

Bake in the preheated oven for half an hour until golden brown and florets are soften. You can check if the cauliflower is ready, inserting the tip of knife – it should come in with no resistance. Baking time depends in the size of cauliflower head, just wait until it’s brown on the outside. This cauliflower was quite big, but you can serve individual small cauliflowers, too.

By the way, you can arrange baby potatoes (cut in half), baby carrots and garlic cloves in the pan around cauliflower. Bake them together with cauliflower, then leave vegetables in pan longer, if needed. Having some extra roasted vegetables on the hand is always good!

Meanwhile cauliflower head is baking make tahini sauce, de-seed the pomegranate and chop parsley.

Serve whole roasted cauliflower, drizzled with tahini sauce, sprinkled with chopped parsley, pomegranate seeds and pine nuts. If you wish you can add sliced almonds instead. I also arranged rocket leaves around whole roasted cauliflower.

How to make tahini sauce

To make tahini, just toast half a cup of sesame seeds on a pan (without oil) until golden brown. Let them cool, then put into food processor with lemon juice, olive oil and a splash of water. Blend until smooth or to your liking. I prefer it thick and chewy, but you can blend it further with more olive oil. Add salt and pepper, if needed.

That is so easy and delicious! Add tahini to salads, toasts and so on. It lasts in the fridge up to 6 months. If you’re not a fan of tahini, you can use this vegan avocado pesto with whole baked cauliflower or any other cauliflower dish. You can also use light soy sauce, whipped feta, yogurt, butter sauce for vegetarian topping.

This vegan meal is so addictive and looks beautiful on the table! I highly recommend trying this whole baked cauliflower – spicy, comforting, perfectly rounded with tahini flavor and fresh pomegranate seeds. When you cut it (do the same like you cut your cake), this vegetable is moist and tender inside. Serve some extra tahini sauce on the side!

This is one of our favorite cauliflower dishes so far. It look so festive, but at the same time – so easy to prepare and serve to your family and friends. Just give it a try!

By the way, we enjoyed whole baked cauliflower cold from the lunch box from the fridge. Just irresistible and tasty in cold mode, too. You can also reheat it in the microwave for about 5 minutes on low or 10-15 minutes in the preheated oven (355 F / 180 C), with a little bit of water. Oven roasted veggies like cauliflower are easy to include in everyday cooking!
