Creating this delicious Bold & Flavorful Harissa Chicken is straightforward if you follow these steps:

1. Marinate the Chicken: In a bowl, mix harissa paste, olive oil, minced garlic, salt, and black pepper. Coat the chicken thighs with this mixture and let them marinate for at least 30 minutes.
2. Preheat the Oven: While the chicken marinates, preheat your oven to 400°F (200°C).
3. Prepare the Vegetables: In a large baking dish, add the halved baby potatoes and sliced leeks. Toss them with a little olive oil, salt, and pepper for seasoning.
4. Arrange the Chicken: Place the marinated chicken thighs on top of the potatoes and leeks in the baking dish. Make sure they are arranged evenly.
5. Bake: Roast in the preheated oven for 45-60 minutes, or until the chicken is cooked through and the skin is crispy. The internal temperature should reach 165°F (75°C).
6. Serve with Yogurt: Once cooked, remove from the oven and let it rest for a few minutes. Serve the chicken and vegetables topped with a generous dollop of yogurt and garnish with fresh parsley and lemon wedges.
