In a large bowl, combine Greek yogurt, lemon juice, olive oil, garlic, ginger, cumin, paprika, turmeric, coriander, garam masala, chili powder, and salt.
Add chicken to the bowl and coat well with the marinade. Cover and refrigerate for at least 2 hours or overnight for best flavor.
Preheat your oven to 425°F (220°C). Line a baking sheet with foil and place a wire rack on top.
Arrange the marinated chicken on the rack and bake for 25–30 minutes, flipping halfway, until slightly charred and cooked through (internal temp should be 165°F).
Optional: Broil for an additional 2–3 minutes for a more charred finish.
Remove from the oven, rest for 5 minutes, and garnish with chopped cilantro and lemon wedges before serving.
