Preheat the oven to 375 degrees Fahrenheit.
Heat 1 tablespoon of olive oil in a large oven-safe pan over medium-high heat.
Season 2 pounds of bone-in, skin-on chicken thighs on both sides with salt and pepper to taste.
Add the chicken thighs to the pan in a single layer. Cook for 5 to 6 minutes on each side, or until they turn a golden brown.
Once browned, remove the chicken from the pan and place it on a plate. Cover it with foil to keep it warm.
Add 1 thinly sliced onion to the pan and sauté for about 5 to 6 minutes until it softens.
Pour in 1 cup of chicken broth, 1 tablespoon of paprika, 2 teaspoons of ground cumin, ¾ teaspoon of ground cinnamon, ½ teaspoon of ground ginger, and ¼ teaspoon of ground turmeric.
Arrange the chicken thighs back into the pan, spooning some of the liquid over them.
Place the pan uncovered into the preheated oven and bake for 25 to 30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165 degrees Fahrenheit.
After removing the pan from the oven, stir in ½ cup of green olives and 1 tablespoon of lemon juice.
Sprinkle 2 tablespoons of chopped parsley over the top just before serving.
Serve the Moroccan Chicken warm, garnished with lemon wedges if desired.
