In a small bowl, combine the following ingredients (excluding paneer, bell pepper, and onion): ginger garlic paste, yogurt, salt to taste, black pepper, cumin, tikka spice powder, chili powder, and dry mango powder. Mix all the ingredients well to create a smooth paste.
Once the paste is ready, add the cubes of paneer, cut bell pepper, and cut onion to the bowl. Mix gently to ensure that all the paneer, bell pepper, and onion pieces are well-coated with the marinade. Cover the bowl and let the mixture marinate for 30 minutes at room temperature. TIP: Marinate for longer time to get the more flavors in paneer and vegetables.
Skew the marinated paneer, bell pepper, and onion. Use wooden skewers and thread the paneer, bell pepper, and onion onto the skewers in the desired order, leaving a bit of room on each skewer to allow for turning during cooking. Leave a small gap after skewering one set (paneer, bell pepper, and onion) to facilitate even cooking.
There are two methods to cook the Paneer Tikka skewers:
Method 1: Heat a grill pan on medium-high heat. Lightly brush ghee or olive oil onto the pan to prevent sticking. Place the skewers on the grill pan and grill them for approximately 2-3 minutes on each side. Make sure to cook all four sides of the paneer cubes for the best results. Brush additional oil or ghee on the skewers as needed during the grilling process.
Method 2: Alternatively, you can follow the same steps as Method 1 and grill the skewers on a barbecue.
Once the Paneer Tikka is cooked to perfection, remove the skewers from the grill pan or barbecue.
To serve: arrange the hot Paneer Tikka skewers on a platter and garnish with fresh coriander or mint leaves.
