Cut the boneless chicken into bite-sized cubes and place them in a mixing bowl.
Add yogurt, ginger-garlic paste, tandoori masala, and lemon juice.
Mix thoroughly until the chicken is evenly coated with the marinade.
Cover and refrigerate for at least 1–2 hours to allow the flavors to develop.
Thread the marinated chicken pieces onto skewers.
Preheat the oven to 425°F (220°C) or prepare a medium-high grill.
Cook for 15–20 minutes, turning occasionally and brushing lightly with oil, until the chicken is cooked through and lightly charred. Ensure the internal temperature reaches 165°F (74°C).
Serve hot with mint chutney, sliced onions, and lemon wedges.
