Preheat oven to 375F.
Start by preparing the chicken. Combine the olive oil, spices, and chicken thighs in a bowl. Toss until the chicken is coated in the oil and spices and then set aside.
In a 9x13 dish, combine the rice, hot broth, turmeric, and salt. Add in the vegetables if using and mix. Place the chicken pieces on top of the rice.
Cover with foil and bake for 30 minutes. Remove the foil and spray the tops of the chicken with cooking spray if desired for extra crispiness.
Bake for an additional 20-30 minutes or until the rice is cooked through.
