Instructions

  1. Step 1: Preheat oven to 425°F. In a small bowl, mix 3 tbsp harissa paste, 3 tbsp olive oil, 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, 2 tsp sea salt, and 1 tsp black pepper.
  2. Step 2: Place 6 bone-in, skin-on chicken thighs on a large rimmed baking sheet. Rub the harissa spice mixture evenly all over the chicken thighs, making sure to get under the skin where possible.
  3. Step 3: Toss 6 cups cauliflower florets in any remaining harissa mixture and spread them out on the baking sheet around the chicken thighs.
  4. Step 4: Roast in the oven for 35-40 minutes, turning the cauliflower halfway through, until chicken skin is crispy and internal temperature reaches 165°F, and cauliflower is tender and caramelized.
  5. Step 5: Remove from oven, sprinkle 1/4 cup chopped fresh parsley over the chicken and cauliflower, and serve hot.
