Heat olive oil in a cast iron skillet over medium high heat.
In a small bowl combine spices, rub 3/4 of the seasoning into the chicken. Pan sear the chicken in the hot oil until browned. Remove chicken from the skillet and set aside.
In the same skillet over medium heat add remaining spices and cook until fragrant, about 1 minute. Add fish sauce, lime zest, chicken broth, coconut milk and lime juice to the skillet.
Place chicken back into the skillet and transfer to oven. Bake the chicken for about 25-30 minutes or until fully cooked to an internal temperature of chicken - about 175 degrees F.
