Preheat the oven to 400°F.
To make the marinade, mix olive oil, yogurt, paprika, cumin, salt, onion powder, ginger, black pepper, turmeric, minced garlic, parsley, and cilantro in a small bowl.
Place the chicken, potatoes, and lemon slices in a large baking dish.
Pour the marinade over the chicken and potatoes, ensuring they're evenly coated. Try to get some marinade under the chicken skin for extra flavor.
Bake in the oven, uncovered, for 50 to 60 minutes until the chicken is fully cooked through. For extra crispiness, broil for 3 to 5 minutes.
Remove from the oven and add the olives and preserved lemons before serving!
