Step-by-Step
Instructions
Here’s how to make Roasted Harissa Cauliflower:
Prepare the Cauliflower:
- Preheat Oven: Preheat your oven to 400°F (200°C).
- Cut the Cauliflower: Wash the cauliflower and cut it into bite-sized florets. Ensure the florets are roughly the same size for even cooking.
- Dry the Cauliflower: Pat the cauliflower florets dry with a clean kitchen towel or paper towels. This step is crucial for achieving a crispy texture.
Make the Harissa Marinade:
- Combine Ingredients: In a large bowl, combine the harissa paste, olive oil, cumin, smoked paprika, garlic powder, salt, and pepper. Mix well until all the ingredients are thoroughly combined.
- Adjust Seasoning: Taste the marinade and adjust the seasoning as needed. If you prefer a spicier dish, add more harissa paste. If you want a milder flavor, add a touch of honey or maple syrup.
Coat and Roast the Cauliflower:
- Coat the Cauliflower: Add the cauliflower florets to the bowl with the harissa marinade. Toss well to ensure each floret is evenly coated. Use your hands to gently massage the marinade into the cauliflower for better flavor absorption.
- Arrange on Baking Sheet: Line a baking sheet with parchment paper. Spread the marinated cauliflower florets in a single layer on the baking sheet. Avoid overcrowding the pan, as this can lead to steaming instead of roasting. If necessary, use two baking sheets.
- Roast: Place the baking sheet in the preheated oven and roast for 20-25 minutes, or until the cauliflower is tender and slightly charred around the edges. Flip the florets halfway through cooking to ensure even roasting.
- Check for Doneness: To check if the cauliflower is done, pierce a floret with a fork. It should be tender and easily pierced. The edges should be golden brown and slightly crispy.
Garnish and Serve:
- Garnish: Remove the roasted cauliflower from the oven and transfer it to a serving dish. Garnish with fresh chopped cilantro.
- Serve: Serve the Roasted Harissa Cauliflower immediately while it is hot and flavorful. Provide lemon wedges for squeezing over the cauliflower to add a touch of brightness.

Additional Tips for Roasted Harissa Cauliflower
Follow these tips for the best Roasted Harissa Cauliflower:
- Use Fresh Cauliflower: Choose a firm, white head of cauliflower with tightly closed florets for the best flavor and texture.

- Add a Touch of Sweetness: A drizzle of honey or maple syrup can balance the spiciness of the harissa paste and add a touch of sweetness.
- Use Fresh Herbs: Fresh cilantro adds a vibrant flavor and visual appeal to the dish.
