Preheat oven to 375℉.
Combine all the Moroccan spice blend ingredients together. The recipe should yield about 8 to 9 tsp or about 3 tbsp.
Season the chicken breasts with 2 tbsp of the Moroccan spice blend thoroughly. Use more as preferred.
In a large Dutch Oven or an oven-safe pot, heat the olive oil over medium-high heat. When the oil is hot, add the chicken breasts and sear on both sides until browned, about 2 to 3 minutes per side. The chicken will not be cooked through at all; it will just be crispy on the outside. Transfer the chicken from the pot to a plate and set aside.
Add the onion and garlic to the pot and sauté for about 3 minutes until the onion softens and becomes translucent, and garlic is aromatic. Add the remaining 1 tbsp of the Moroccan spice blend and stir.
Add the golden raisins, chickpeas, fire roasted tomatoes, chicken broth, couscous, and stir well. Gently stir in the kale. Bring to a boil, then add the chicken breasts back.
Cover the pot with a lid and place it in the oven. If your pot doesn't have a lid, cover with aluminum foil. Cook in the oven for 30 minutes with the lid on, then remove the lid and cook for an additional 30 minutes.
