01 - Preheat the oven to 400°F.
02 - In a large bowl, combine the olive oil, sumac, cumin, smoked paprika, coriander, salt, and black pepper. Mix until a smooth paste forms.
03 - Add the chicken thighs to the bowl and turn to coat each piece thoroughly in the spice mixture, ensuring even coverage on all sides.
04 - Spread the sliced carrots, drained chickpeas, red onion, and minced garlic in a roasting pan or large baking dish. Drizzle lightly with olive oil, season with a pinch of salt, and toss to combine.
05 - Arrange the seasoned chicken thighs skin-side up on top of the vegetable mixture in the roasting pan.
06 - Roast in the oven for 40–45 minutes until the chicken skin is golden brown and crisp, the internal temperature reaches 165°F, and the carrots are fork-tender.
07 - Remove from the oven, scatter chopped fresh parsley over the top, and serve immediately with lemon wedges on the side.
