When it comes to preparing a delicious whole roasted harissa cauliflower, the key is in the preparation. These simple steps will ensure that your cauliflower is perfectly seasoned and roasted.

Preheat The Oven

First, preheat your oven to 400°F (200°C). This will ensure the cauliflower cooks evenly and develops a beautiful golden color.

Prepare The Cauliflower

While the oven is preheating, prepare the cauliflower by removing the outer leaves and trimming the stem, leaving the core intact. This will help the cauliflower hold its shape while roasting. Rinse the cauliflower under cold water to remove dirt or debris, then dry it with a clean towel.

Next, place the cauliflower on a cutting board and carefully cut a deep cross into the base, about 1 inch deep. This will help the marinade penetrate the cauliflower and infuse it with flavor as it roasts.

Make The Harissa Marinade

To make the harissa marinade, start by gathering the following ingredients:

  • Two tablespoons of olive oil
  • Two tablespoons harissa paste
  • One tablespoon of lemon juice
  • One teaspoon of ground cumin
  • One teaspoon of smoked paprika
  • 1/2 teaspoon salt

In a small bowl, whisk together the olive oil, harissa paste, lemon juice, cumin, smoked paprika, and salt until well combined. The harissa paste adds a spicy kick to the marinade, while the lemon juice and spices provide flavor. Adjust the ingredients to taste, adding more harissa paste for extra heat or more lemon juice for acidity.

Once the marinade is ready, use a brush or hands to coat the cauliflower with the harissa mixture, ensuring you get into all the nooks and crannies. This will ensure that every bite of the roasted cauliflower is flavorful.

Now that the cauliflower is prepared and the oven is preheated, it’s time to roast. Place the cauliflower in a baking dish or on a baking sheet lined with parchment paper, then transfer it to the preheated oven. Roast for approximately 45 minutes to 1 hour until the cauliflower is tender and the outer edges are caramelized.

Once the whole roasted harissa cauliflower is done, please remove it from the oven and let it rest for a few minutes before slicing. This will allow the flavors to develop fully and the cauliflower to cool slightly for easier handling.

Serve the roasted harissa cauliflower as a main dish or a flavorful side. It pairs well with a creamy yogurt sauce or a tangy tahini dressing. Enjoy the bold flavors and tender texture of this delicious roasted vegetable dish!

Coat The Cauliflower With Harissa Marinade

To infuse the cauliflower with bold, spicy flavors, start by coating it with an irresistible harissa marinade. This North African hot chili paste is renowned for its vibrant combination of roasted red peppers, garlic, and aromatic spices. Follow these steps to ensure every nook and cranny of the cauliflower is not deprived of this delectable coating:

  1. Preheat your oven to 400°F (200°C) for the optimal roasting temperature.
  2. Prepare your harissa marinade in a small bowl by combining two tablespoons of harissa paste, one tablespoon of olive oil, and a pinch of salt.
  3. Place the whole cauliflower on a baking sheet lined with parchment paper or a silicone mat.
  4. Using a basting brush or your hands, generously coat the cauliflower with the harissa marinade, covering the entire surface.

Roast The Cauliflower

Once the cauliflower is perfectly coated, it’s time to unleash its full potential through roasting. Follow these steps to achieve a beautifully golden and tender whole-roasted harissa cauliflower:

  1. Place the baking sheet with the cauliflower in the preheated oven.
  2. Roast the cauliflower for approximately 40–45 minutes, or until it is tender when pierced with a fork. The outer layer should develop a crispy, caramelized texture.
  3. Every 15 minutes, carefully open the oven and use a spoon or basting brush to drizzle any excess harissa marinade from the baking sheet onto the cauliflower. This will ensure the flavors penetrate deeply into the vegetable.
  4. Rotate the cauliflower halfway through the cooking process, allowing it to roast evenly on all sides.

Once roasted to perfection, remove the cauliflower from the oven and let it rest for a few minutes. This will allow the flavors to meld together and the steam to escape, resulting in a firmer texture.
