1. Season chicken with salt and pepper. In a large Dutch oven or heavy pot, heat oil over medium-high. In batches, if necessary, cook chicken skin side down until browned, about 7 minutes. Transfer to plate.

2. Reduce heat to medium. Add onion and saute until soft and translucent, about 5 minutes, scraping up any browned bits from pot. Add 2 tablespoons water.

3. Add garlic, cumin, and chipotle; cook until garlic is soft and fragrant, about 2 minutes. Add tomatoes, season, and bring to a simmer; cook 5 minutes, breaking tomatoes down with a wooden spoon. Return chicken and any accumulated juices to pot; bring to a simmer, cover, and cook until chicken is cooked through, about 15 minutes. Serve over rice.
