Getting your ingredients right is the secret to nailing the Ottolenghi-Inspired Whole Roasted Cauliflower with Tahini Sauce Recipe. Each element plays a vital role: from the oils that create a crisp, caramelized exterior to the fresh herbs that add bursts of color and flavor.

  • Whole cauliflower (medium to large): The star of the dish offering a hearty and satisfying base.
  • Olive oil (3 tablespoons): Adds richness and helps achieve that golden, crispy roast.
  • Coconut oil (~¼ cup, melted): Lends a subtle sweetness and moisture, ensuring the cauliflower doesn’t dry out.
  • Sea salt (½ teaspoon): Enhances all the flavors and balances the richness.
  • Tahini (50 grams or about 3 ½ tablespoons): Creamy sesame paste that gives the sauce its signature nutty depth.
  • Lemon juice (1 tablespoon): Brings brightness and a fresh tang to the tahini sauce.
  • Pinch of salt: To season the tahini sauce perfectly.
  • Water (4 tablespoons or more as needed): Thins the tahini to a smooth consistency for easy drizzling.
  • Garlic powder or fresh garlic (optional): Adds aromatic warmth and complexity if you love a little garlicky punch.
  • Chopped roasted nuts (such as walnuts or pine nuts): For a satisfying crunch and earthy undertone as a garnish.
  • Fresh herbs like parsley or coriander (finely chopped): Add vibrant color and fresh herbal notes.

How to Make Ottolenghi-Inspired Whole Roasted Cauliflower with Tahini Sauce Recipe

Step 1: Prep and Parboil the Cauliflower

Start by removing the cauliflower’s top leaves while keeping most of the bottom leaves intact—they’ll turn delightfully crispy when roasted. Give your cauliflower a good wash, then bring a pot of water to boil, filling about three-quarters full. Carefully submerge the cauliflower head upside down in the boiling water, leaving the base slightly exposed. Parboil it for about 5 to 10 minutes until tender but still firm—this softens the core, speeding up roasting and ensuring a tender texture without falling apart.

Step 2: Preheat and Oil Preparation

While the cauliflower drains, preheat your oven to 170°C (338°F). In a small bowl, combine your melted coconut oil and olive oil with sea salt—this luscious oil mix will help the cauliflower develop an irresistible golden crust packed with savory depth.

Step 3: Roast the Cauliflower

Place the steamed cauliflower upright on a baking sheet lined with parchment. Using a silicone brush, coat it generously with half of your oily salt blend. Roast for one hour, then pull it out to brush the remaining oil all over. Return it to the oven for another 30 minutes to an hour depending on size, until deeply golden and tender—you’ll know it’s ready when the leaves are crisp and charred, creating a spectacular contrast of textures.

Step 4: Prepare the Tahini Sauce

While the cauliflower roasts, whisk your tahini with lemon juice, salt, and water. Add water little by little, stirring until the sauce is smooth, velvety, and pourable—thicker if preferred, but perfect for drizzling. A pinch of garlic powder or fresh minced garlic is optional for an extra flavor kick.

Step 5: Finish and Garnish

Remove the cauliflower from the oven and let it rest for about five minutes. Pour your heavenly tahini sauce over the top, then sprinkle with crunchy roasted nuts and a scattering of fresh herbs like parsley or coriander to bring a vibrant, flavorful punch.

Garnishes

Add chopped toasted walnuts or pine nuts along with fresh herbs to brighten the plate. These toppings create amazing texture, fragrance, and a beautiful color contrast against the golden cauliflower and creamy sauce.

Side Dishes

This dish pairs wonderfully with warm, fluffy flatbreads, a simple green salad, or fluffy couscous to soak up every drop of that luscious tahini sauce. It also complements grilled meats or fish for a well-rounded meal.

Creative Ways to Present

Slice the whole roasted cauliflower into thick wedges for easy sharing, or gently pull it apart by hand into rustic florets. Serving it whole on a large platter surrounded by herbs creates an impressive centerpiece that is both inviting and Instagram-worthy.

Make Ahead and Storage

Storing Leftovers

Leftover cauliflower keeps well refrigerated in an airtight container for up to three days. Keep the tahini sauce separate until ready to serve to maintain its fresh texture.

Freezing

While the roasted cauliflower can be frozen, the texture of the florets may change slightly. Freeze in a freezer-safe container for up to one month and thaw overnight in the fridge before reheating.

Reheating

Reheat gently in a low oven to prevent drying out, or warm in the microwave covered with a damp paper towel. Add fresh garnishes and drizzle with tahini sauce right before serving again for maximum flavor.

FAQs

Can I use a different oil instead of coconut oil?

Absolutely! While coconut oil adds a subtle sweetness and creamy texture, you can substitute it with more olive oil or avocado oil, which also promote beautiful roasting and rich flavor.

Is this recipe vegan and gluten-free?

Yes, the entire Ottolenghi-Inspired Whole Roasted Cauliflower with Tahini Sauce Recipe is naturally vegan and gluten-free, making it an inclusive dish for many dietary preferences.

How do I know when the cauliflower is fully cooked?

Check tenderness by inserting a knife or skewer into the core—it should glide in easily without causing the cauliflower to fall apart. The exterior should look golden with some crispy, charred leaves.

Can I prepare the tahini sauce ahead of time?

Yes, the tahini sauce can be mixed a day in advance and stored in the fridge. Just give it a good stir before serving, as it may thicken or separate slightly when chilled.

What can I serve if I want to make this a full meal?

Pair the roasted cauliflower with hearty grains like quinoa or farro, a simple bean salad, or roasted root vegetables to create a satisfying, balanced meal that feels wholesome and indulgent.

This Ottolenghi-inspired Whole Roasted Cauliflower recipe features a perfectly tender and golden roasted cauliflower, enhanced with a luscious tahini sauce, crispy roasted cauliflower leaves, and a garnish of toasted nuts and fresh herbs. The cauliflower is first boiled to tenderness, then brushed with a coconut oil and olive oil blend before slow roasting to achieve rich color and crispiness. This hearty vegetarian dish makes a stunning centerpiece or a flavorful side.

  • Total Time: 1 hour 10 minutes
  • Yield: 2 servings

Ingredients

Cauliflower

  • 1 whole medium to large cauliflower
  • 3 tablespoons olive oil
  • ¼ cup (35 grams) coconut oil, melted at room temperature
  • ½ teaspoon sea salt

Tahini Sauce

  • 50 grams (about 3 ½ tablespoons) tahini
  • 1 tablespoon lemon juice
  • Pinch of salt
  • 4 tablespoons water (more if needed)
  • Optional: ½ teaspoon garlic powder or 1 small garlic clove, finely chopped

Garnish

  • Chopped roasted nuts such as walnuts or pine nuts
  • Fresh herbs such as parsley, mint, or coriander, finely chopped

Instructions

  1. Prepare Cauliflower: Remove the leaves on top of the cauliflower using a knife or your hands, leaving most of the bottom leaves intact to roast crispy. Wash the cauliflower thoroughly.
  2. Boil Cauliflower: Fill a large pan about ¾ full with water and bring to a boil. Carefully place the cauliflower head down into the water so the base protrudes slightly. Boil for 5-10 minutes until the cauliflower begins to become tender but does not fall apart.
  3. Drain: Remove the cauliflower from the boiling water and place it in a colander to drain completely.
  4. Preheat Oven: Set the oven to 170°C (338°F) to preheat while you prepare the oil mixture.
  5. Mix Oils and Salt: In a small bowl, combine the melted coconut oil, olive oil, and sea salt until well blended.
  6. Apply Oil Mixture: Place the drained cauliflower head upright on a lined baking tray. Using a silicone pastry brush, evenly spread half of the oil-salt mixture over the cauliflower, making sure to coat the exposed leaves and surface.
  7. Roast First Stage: Roast the cauliflower in the preheated oven for about 1 hour until starting to turn golden and tender.
  8. Apply Remaining Oil: Remove the cauliflower from the oven and brush with the remaining oil-salt mixture to enhance flavor and promote crisping.
  9. Roast Second Stage: Return the cauliflower to the oven for an additional 30 to 60 minutes, depending on size, until it is very tender and golden brown with crispy, charred leaves.
  10. Rest: Remove the cauliflower from the oven and let it rest for 5 minutes to retain juices.
  11. Make Tahini Sauce: In a small bowl, whisk tahini with lemon juice, salt, water, and optional garlic powder or chopped garlic to create a smooth, creamy sauce. Adjust water or tahini quantities to achieve desired runny consistency.
  12. Serve: Drizzle the tahini sauce generously over the roasted cauliflower. Garnish with chopped roasted walnuts or pine nuts and finely chopped fresh herbs (parsley, mint, or coriander).
  13. Slice and Enjoy: Cut the roasted cauliflower into thick slices or pull apart with your hands to serve.

Notes

  • Keep some of the bottom cauliflower leaves on for roasting; they become crispy and add texture.
  • Boil cauliflower just to tenderize, avoiding overcooking to maintain structure for roasting.
  • You can substitute the coconut oil with additional olive oil if preferred.
  • The roasting time may vary depending on the size of the cauliflower; larger heads require longer roasting for tenderness.
  • The tahini sauce consistency can be adjusted with water or tahini to suit taste.
  • Fresh herbs and nuts can be customized based on availability or preference.
