1. Gather Your Ingredients
For the cauliflower:
- One large head of cauliflower (about 2 pounds), cut into florets
- Three tablespoons olive oil
- Two tablespoons harissa paste (store-bought or homemade)
- Two garlic cloves, minced
- One teaspoon ground cumin
- One teaspoon ground coriander
- Half teaspoon smoked paprika
- Half teaspoon salt
- Quarter teaspoon black pepper
- Two tablespoons fresh lemon juice
- One teaspoon honey or maple syrup
For garnish and serving:
- Quarter cup fresh cilantro, chopped
- Quarter cup fresh parsley, chopped
- Two tablespoons toasted sesame seeds or slivered almonds
- Lemon wedges for serving
- Optional: tahini sauce or yogurt sauce for drizzling
2. Prepare the Cauliflower
Preheat your oven to 425 degrees Fahrenheit and line a large baking sheet with parchment paper. Higher heat is essential for getting those caramelized, crispy edges. Remove the leaves and thick stem from the cauliflower head. Cut the cauliflower into florets about 1 to 1.5 inches in size, trying to keep them relatively uniform so they roast evenly. Don’t discard the smaller pieces that break off, as these will get extra crispy and are often the most delicious parts. If any florets are particularly large, cut them in half so everything cooks at the same rate. You should have about 6 to 7 cups of cauliflower florets.
3. Make the Harissa Coating
In a large mixing bowl, combine three tablespoons of olive oil, two tablespoons of harissa paste, minced garlic, ground cumin, ground coriander, smoked paprika, salt, black pepper, lemon juice, and honey or maple syrup. Whisk everything together vigorously until you have a smooth, well-combined paste. The honey balances the heat from the harissa and helps the cauliflower caramelize beautifully in the oven. Taste the mixture and adjust the seasoning if needed. If you like more heat, add extra harissa paste. If you prefer it milder, add a bit more honey and olive oil to mellow the spice.
4. Coat the Cauliflower
Add all the cauliflower florets to the bowl with the harissa mixture. Use your hands or a large spoon to toss the florets thoroughly, making sure every piece is evenly coated with the spice paste. Really work the mixture into all the nooks and crannies of the cauliflower. Let the cauliflower sit in the bowl for about 5 minutes if you have time. This brief marinating period allows the flavors to penetrate the florets more deeply and results in more flavorful cauliflower. The cauliflower should be completely coated with a vibrant red-orange paste.
5. Arrange for Roasting
Spread the coated cauliflower florets in a single layer on your prepared baking sheet. This is important, so don’t skip it or pile the florets on top of each other. Overcrowding causes steaming instead of roasting, which means you’ll get soft, pale cauliflower instead of crispy, caramelized florets. If all your cauliflower doesn’t fit in a single layer, use two baking sheets rather than crowding everything onto one. Leave a little space between each floret to allow hot air to circulate. Scrape any remaining harissa mixture from the bowl and drizzle it over the cauliflower.
6. Roast the Cauliflower
Place the baking sheet on the middle rack of your preheated oven. Roast for 15 minutes without disturbing the cauliflower. This initial undisturbed roasting time allows the bottoms to develop a nice caramelized crust. After 15 minutes, remove the pan from the oven and use a spatula to flip and stir the cauliflower pieces, turning them so different sides can caramelize. Return the pan to the oven and roast for another 15 to 20 minutes, stirring once more halfway through. The cauliflower is done when it’s tender when pierced with a fork and has deep golden-brown, slightly charred edges. The smaller pieces should be extra crispy.
7. Check for Doneness
The total roasting time will be 30 to 35 minutes, but this can vary depending on the size of your florets and your oven. The cauliflower should be fork-tender but not mushy, with visible char marks and crispy, caramelized edges. If your cauliflower is tender but not as crispy as you’d like, turn on the broiler for the last 2 to 3 minutes, watching carefully to prevent burning. The high heat from the broiler will crisp up the edges quickly. Remove from the oven when the cauliflower has reached your desired level of crispiness and caramelization.
8. Add Fresh Elements
Transfer the roasted cauliflower to a serving platter or bowl. While it’s still hot, sprinkle the chopped fresh cilantro and parsley over the top. The fresh herbs add a bright, cooling contrast to the warm spices and look beautiful against the golden cauliflower. Sprinkle toasted sesame seeds or slivered almonds over everything for added crunch and nutty flavor. If you haven’t toasted your nuts or seeds yet, you can do this quickly by placing them in a dry skillet over medium heat for 2 to 3 minutes, stirring frequently until golden and fragrant.
9. Serve and Enjoy
Serve the Moroccan Harissa Roast Cauliflower immediately while it’s hot and at its crispiest. Arrange lemon wedges around the platter so guests can squeeze fresh lemon juice over their portions for extra brightness. The acidity from the lemon beautifully cuts through the richness of the spices. If desired, drizzle tahini sauce or a simple yogurt sauce over the top, or serve it on the side for dipping. This cauliflower is incredibly versatile and can be served as a side dish, spooned over grains like couscous or quinoa, stuffed into pita bread, or tossed with pasta for a complete meal.
Tips for Perfect Results
- Don’t crowd the pan. This is the single most important factor in getting crispy, caramelized cauliflower. Give each floret space to breathe and roast properly.
- Cut the florets into similar sizes so they cook evenly. Smaller pieces will get crispier, while larger pieces will be more tender inside.
- High heat is essential for roasting. Don’t be tempted to lower the temperature or your cauliflower will steam and become soft instead of developing those crispy, caramelized edges.
- Harissa paste varies significantly in heat level between brands. Start with less if you’re heat-sensitive, taste the mixture, and add more as desired.
- Make your own harissa paste if you can’t find it in stores by blending roasted red peppers, dried chilies, garlic, cumin, coriander, and olive oil together.
- Let the cauliflower sit undisturbed for the first 15 minutes of roasting. Resist the urge to check on it or stir it too early, as this prevents proper caramelization.
- The cauliflower can be prepped and coated in the harissa mixture up to 24 hours ahead. Store it covered in the refrigerator and bring to room temperature before roasting.
- For extra richness, drizzle a tablespoon of melted butter over the cauliflower during the last 5 minutes of roasting for an added layer of flavor.
- Save the small crispy bits that break off during cutting and roasting. These are like cauliflower chips and are absolutely delicious for snacking.
- Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in a 400-degree oven for 8 to 10 minutes to restore crispiness, or enjoy cold in salads and grain bowls where the texture doesn’t matter as much.
