Instructions

  1. Step 1: Preheat the oven to 425°F. In a large bowl, whisk together 3 tbsp harissa paste, 3 tbsp extra virgin olive oil, 4 minced garlic cloves, 1 tsp ground cumin, 1 tsp ground coriander, 1 tsp smoked paprika, 1 1/2 tsp sea salt, 1/2 tsp black pepper, and 1 tbsp fresh lemon juice until smooth.
  2. Step 2: Add 6 bone-in, skin-on chicken thighs and 4 cups cauliflower florets to the bowl. Toss well to evenly coat the chicken and cauliflower with the harissa marinade.
  3. Step 3: Arrange the chicken thighs skin-side up on a large rimmed baking sheet, spacing them evenly. Scatter the cauliflower florets around the chicken.
  4. Step 4: Roast in the preheated oven for 35-40 minutes until the chicken skin is crispy and the internal temperature reaches 165°F, and the cauliflower is tender and slightly browned.
  5. Step 5: Remove from oven and sprinkle with 1/4 cup chopped fresh parsley before serving warm.
