Step 1

Heat oil in a Dutch oven or heavy pot over medium-high heat. Sprinkle chicken with 1 tsp salt and cook for 2 minutes on each side, until lightly browned (you may need to do this in 2 batches); remove chicken to a plate.

Step 2

Reduce heat to medium; add onion and cook until softened, stirring occasionally, 3-4 minutes. Add ginger, garlic, cumin, paprika, turmeric, cinnamon, cayenne and remaining 1 tsp salt; cook, stirring, 1 minute. Pour in broth and orange juice; scrape bottom of pan with a wooden spoon, releasing all the browned bits.

Step 3

Add squash; bring to a boil over high heat. Cover and reduce heat to medium-low; simmer 5 minutes. Stir in orange zest, orange slices, olives, raisins and reserved chicken (including any accumulated juices); simmer, stirring occasionally, until chicken is cooked and squash is tender, 10 minutes more. Stir in parsley.
