Preheat the Oven: Preheat the oven to 400°F.
Season the Chicken: In a small bowl, mix together the spices, lemon zest, salt, and pepper. Pat the chicken thighs very dry with paper towels, then season generously on all sides.
Sear the Chicken: Heat a wide Dutch oven or braiser over medium heat and drizzle with olive oil. Sear the chicken skin-side down until deeply golden, about 3–4 minutes, then flip and cook the other side for 2 minutes. Remove chicken to a plate.
Build the Flavor Base: In the same pan, sauté the shallots until softened and lightly caramelized, about 2–3 minutes. Add the garlic and sauté for 1–2 minutes until fragrant.
Toast the Rice: Add the basmati rice and stir to coat the grains in the rendered chicken fat. Add the chickpeas and cook for 1 minute, stirring to combine.
Assemble the Dish: Nestle the chicken thighs back into the rice mixture, skin-side up. Pour the chicken broth around the chicken (not over it) and scatter the lemon slices on top.
Bake: Turn off the stovetop heat, cover the pot, and transfer to the oven. Bake for 20 minutes, then uncover and continue cooking for 10 more minutes, until the liquid is absorbed and the chicken is cooked through.
Finish and Serve: Remove from the oven, garnish with fresh parsley, and serve warm.
