Season chicken with salt, pepper, paprika, cumin, coriander, turmeric, garlic powder, and cinnamon.
Heat olive oil in a large pot and cook chicken 5–6 minutes until browned, then remove.
In the same pot, sauté onion and garlic 2–3 minutes until softened.
Stir in rinsed rice and toast 1–2 minutes.
Pour in chicken broth and lemon juice and bring to a gentle boil.
Return chicken to pot, cover, and reduce heat to low.
Simmer 18–20 minutes until rice is tender and liquid is absorbed.
Fluff rice, garnish with parsley, and serve with yogurt sauce if desired.
