Add the Greek yogurt, ginger and garlic paste, Madras curry powder, cumin, turmeric, smoked paprika, chilli powder, lemon juice, salt, and black pepper into a large mixing bowl.
Add the chicken pieces and mix thoroughly until every piece is coated in the marinade.
Cover the bowl and refrigerate for at least 3 hours, but overnight is best for maximum flavor.
Preheat the grill to high heat.
Thread the marinated chicken pieces onto metal skewers, packing them closely together while leaving excess marinade behind.
Place the skewers on a baking tray and grill for 4–5 minutes until slightly charred.
Flip the skewers and continue cooking for another 4–5 minutes or until the Chicken Tikka Recipe is fully cooked and charred around the edges.
Serve hot with flatbreads, cooling raita, lettuce, and pink pickled onions.
