Preheat the oven to 375 degrees Fahrenheit.
Pat dry the chicken thighs and drumsticks with a kitchen towel and set them aside.
In a 9x13 baking tray, add the halved potatoes, cherry tomatoes, and garlic. Massage the vegetables with olive oil and season them with salt and pepper.
Arrange the chicken over the vegetables and coat them well with harissa paste on both sides.
Place the tray in the oven and bake for 35-40 minutes, or until the chicken is cooked through.
Once done, transfer the chicken and vegetables to a serving plate, garnish them with parsley, and serve alongside a wedge of lemon on the side.
