By Sarah Johnson · October 18, 2026

What Is Harissa?

Harissa is a North African chili paste made from roasted red peppers, baklouti peppers, garlic, caraway, and coriander. It adds smoky heat and complexity to any roasted vegetable.

Ingredients

2 sweet potatoes, cubed
1 head cauliflower, cut into florets
2 bell peppers, sliced
1 red onion, quartered
3 tbsp harissa paste
3 tbsp olive oil
1 tsp ground cumin
Salt to taste
Fresh cilantro for garnish

Instructions

Preheat oven to 425°F (220°C). Whisk harissa, olive oil, cumin, and salt in a large bowl. Add vegetables and toss until evenly coated.

Spread in a single layer on a parchment-lined baking sheet. Roast 25-30 minutes, turning once halfway, until edges are caramelized and vegetables are tender.

Garnish with fresh cilantro and a squeeze of lemon juice.
