There are so many ways to enjoy cauliflower. Now, I’m not one to use it instead of rice or pizza crust but I love making a roasted cauliflower salad as a side dish or adding it to vegetable tikka masala. We also enjoy our cauliflower fritters or roasted cauliflower soup with some crusty bread for dinner every now and then.

This roasted cauliflower head is another favorite way to serve cauliflower in our home. It’s an easy recipe that my whole family loves, especially when served with tahini yogurt sauce.

Ingredients For Whole Roasted Cauliflower

To make this recipe you need cauliflower, spices, olive oil, yogurt and tahini plus lemon.
  • Cauliflower: You need a whole head of cauliflower for this recipe. Make sure it doesn’t have any brown or soft spots and the florets are intact.
  • Spices: A combination of sumac, oregano, Aleppo pepper, salt, cumin, coriander, paprika and garlic powder adds a lot of flavor to this dish.
  • Olive oil: You need a good amount of olive oil to mix with all the spices to make a paste.
  • Tahini yogurt sauce: This sauce is very similar to our middle eastern tahini sauce and you need tahini, garlic, yogurt, lemon, salt and pepper to make it.

How To Roast Whole Cauliflower

Mix the spices and rub over the cauliflower. Roast in the oven and slice.
  1. Wash and dry the cauliflower, then remove the leaves and trim the bottom stem so it can stand. Make sure not to go too deep so the florets stay intact.
  2. Mix the spices with the olive oil and rub it all over the cauliflower, making sure all parts of it are fully coated with the spice mix.
  3. Cover with a piece of aluminum foil and roast in the oven at 425 degrees F for 45 minutes or until a knife inserted into the cauliflower comes out clean.
  4. Remove the aluminum foil and roast for another 10 minutes for the cauliflower to crisp up just a bit.
  5. Meanwhile, make the tahini yogurt sauce and set it aside.
  6. Drizzle the sauce all over the roasted whole cauliflower and serve.

Tips For Roasting A Whole Cauliflower

  • Season well: Cauliflower doesn’t have a strong flavor, so be sure to rub it very well with the spice mix to make sure every bite is seasoned well.
  • Trim carefully: When trimming the bottom of the cauliflower, make sure to remove most of the stem while keeping the florets intact.
  • Heat: When it comes to roasting vegetables, heat plays an important role. Roast your vegetables at 400 to 425 degrees F for them to keep their shape while being crispy in the outside and tender on the inside.

Variations

The combination of spices I mentioned here gives you a delicious and tasty roasted cauliflower with a Mediterranean flair. However, you can always add or remove any of the spices you don’t have on hand.

What To Serve With Cauliflower

While the tahini yogurt sauce is a wonderful addition to this dish, you can also use other sauces such as toum, ezme, zhoug or aioli to dip the cauliflower pieces in.

Serve this whole roasted head of cauliflower as a vegetarian main course with side dishes such as Greek potatoes, vermicelli rice, bulgur pilaf or herb rice. You can also serve it as a side dish with Italian skillet chicken, balsamic chicken or baked salmon with lemon and garlic.

Leftovers And Reheating

Store the leftovers in an airtight container and refrigerate for up to 3 days. Reheat using a microwave or in the oven at 250 degrees F for 15 to 20 minutes.

To freeze whole roasted cauliflower, Slice it into smaller pieces and place it in a freezer bag. Freeze for up to 3 months and thaw it in the fridge before reheating and serving.

Frequently Asked Questions

How do you know when cauliflower is fully cooked?

To ensure that the whole cauliflower is fully cooked, insert a knife and if it goes in smoothly, the vegetable is fully cooked and ready to serve.

Why is my roasted cauliflower tough?

You’ve undercooked it. If it’s still tough after the cooking time is up, roasted it for another 10 minutes. When roasted well enough, the cauliflower is tender and slightly sweet.

How long to roast a whole head of cauliflower?

This depends on the size of the cauliflower. It usually takes 30 to 45 minutes to roast a whole head of cauliflower followed by a few minutes uncovered to crisp in slightly.
