Preheat your oven to 375°F (190°C).
In a small bowl, mix together the salt, black pepper, cumin, coriander, cinnamon, turmeric, and cayenne pepper. Rub this spice mixture all over the chicken thighs.
In a large oven-safe skillet, heat the olive oil over medium-high heat. Add the chicken thighs, skin side down, and sear for about 5-7 minutes until golden brown. Flip the chicken and sear the other side for an additional 5 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, add the chopped onion and sauté for about 5 minutes until softened. Add the minced garlic and cook for another minute until fragrant.
Pour in the chicken broth and bring to a simmer. Add the saffron threads and pomegranate molasses, stirring to combine.
Return the chicken to the skillet, skin side up, and spoon some of the sauce over the top.
Transfer the skillet to the preheated oven and bake for 30-35 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Remove from the oven and let it rest for 5 minutes before serving. Garnish with pomegranate seeds and chopped parsley.
