MIX together the cumin, coriander, turmeric, paprika, garam masala, garlic, ginger, lemon juice, olive oil, and salt in a large bowl.
ADD the chicken to the bowl and toss to coat evenly in the marinade.
COVER the bowl with plastic wrap and refrigerate for at least 30 minutes or overnight.
PREHEAT the oven to 425°F (218°C).
LINE a baking sheet with parchment paper and place a wire rack on top. Alternatively, thread the chicken pieces onto metal or wooden skewers.
PLACE a pot of water in the bottom of the oven to create steam and keep the chicken moist during cooking.
ARRANGE chicken pieces on the wire rack or skewers, spacing them out evenly.
BAKE the chicken for 20-25 minutes, rotating the skewers every few minutes if using, until cooked through and slightly charred on the outside.
REMOVE the chicken from the oven and let it rest for a few minutes before serving.
GARNISH with fresh cilantro and lemon wedges, and enjoy!
