Place the chicken in a zip lock bag or sealable container with ½ cup coconut milk, ground cinnamon, paprika, and ½ teaspoon sea salt. Seal the bag and shake around until everything is well combined and the chicken is submerged in the marinade mixture. Refrigerate at least 1 hour, up to 12 hours.

Heat the ghee in a medium saucepan over medium-high heat. Add the onion and sauté, stirring occasionally, until onion is translucent and begins to brown, about 8 minutes. Add the garlic and ginger and continue cooking, stirring frequently, until garlic is very fragrant, about 2 to 3 minutes.

Add the remaining ingredients for the sauce and bring to a full but gentle boil. Reduce heat, cover, and cook, stirring occasionally for at least 20 minutes (the longer you cook this sauce, the more flavorful it will become).

Preheat the oven to 350 degrees F, and lightly spray or oil a large casserole dish.

Transfer the chicken to the casserole dish and bake on the center rack of the oven for 30 minutes, or until chicken is cooked through and reaches an internal temperature of 165 degrees F.

Allow the chicken to cool 15 minutes to allow the juices to distribute throughout the meat. This will help make the meat very tender.

Transfer the chicken to a cutting board and chop into bite-sized cubes.

Add the chicken to the saucepan with the butter chicken sauce and return to a gentle boil. Cook, uncovered, stirring occasionally, for 20 to 30 minutes. Stir in fresh chopped cilantro.

Serve Butter Chicken with quinoa, cauliflower rice or rice of choice.
