Before You Start
Think of paneer tikka as the vegetarian answer to chicken tikka. It borrows the same tandoor-style method, and it is usually the first meatless dish you will see on a tandoori menu. It also happens to be a good thing to make for a party or a barbecue at home. Most of the flavour is settled before the skewers go anywhere near the heat. A thick yogurt coating clings to the paneer, and ginger-garlic paste, warm spices and a little mustard oil or lemon add the smoky tang that a few minutes of grilling cannot build alone.
Here is the part that surprises people. Paneer is already a cooked dairy product, so you are not trying to cook it through the way you would with raw chicken. Your only jobs at the grill are to get colour and char on the outside and to warm the middle without drying it out. If you treat it like meat and leave it on for ages, it ends up dry and squeaky. Quick, hot and attentive is the right approach.
Where This Dish Comes From
Paneer tikka grew out of the North Indian tandoori tradition, the same body of tandoor-oven cooking in Punjab that gave us chicken tikka, and it is essentially a vegetarian twist on those dishes. It spread widely from the middle of the 20th century. Many tandoori restaurants were opened by Punjabi families who had moved after Partition, and they brought tandoor cooking first to Delhi and later to the rest of India and abroad. Paneer tikka was devised so that vegetarian guests at those restaurants could order something with the same smoky, charred character as the meat dishes beside it on the menu. Unlike some chaat dishes, it has no murky ancient legend attached. It is a 20th-century restaurant creation resting on a far older tandoor tradition, and that history is fairly well recorded.
Step by Step
-
Prep
Stir together the marinade
Start by whisking the yogurt until it has no lumps. Then add the ginger-garlic paste, roasted gram flour, chilli powder, turmeric, ground coriander, garam masala, crushed kasuri methi, mustard oil or lemon juice, and salt, and stir until the mixture looks even. The roasted besan is there for a reason. It gives the marinade something to grip, so it stays on the paneer and vegetables instead of dripping off, and it browns at the edges where plain yogurt would just steam.

Prep
Coat the paneer gently
Put the paneer, bell pepper and onion into the bowl and fold them through with a light hand. Paneer can be soft and crumbly at the corners, so you want every piece covered without breaking any. Cover the bowl and chill for at least 1 hour and up to 4 hours. If you leave it much longer, the acid in the yogurt starts to turn the paneer slightly mealy.
-
Assemble
Build the skewers
Slide the pieces onto skewers, alternating paneer, pepper and onion so that everything cooks at a similar pace and the skewers look good on the plate. Keep a little space between the pieces. Packed in tightly, they shield each other from the heat and the sides stay pale.
-
Cook
Grill or broil until the edges char
Brush the skewers lightly with oil. Cook over medium-high heat on a grill, or under a hot oven broiler, turning every 2 to 3 minutes for 10 to 12 minutes in all. You are done when the paneer and vegetables have charred spots and are hot all the way through. In an oven, set the rack close to the top element for better colour, and stay nearby, because broilers differ a lot in strength and a skewer can go from charred to burnt quickly.

Serve
Finish at the table
While the skewers are still hot, squeeze a little lemon over them and, if you like, dust on some chaat masala. Bring them out straight away with mint chutney and sliced onion rings, while the smoky aroma is at its strongest and the paneer is warm and tender.
Swaps That Work
Firm tofu will stand in for paneer. The texture is close, though the flavour is different, and you should press the tofu first to squeeze out water, otherwise it dilutes the marinade. If you have no mustard oil, or the sharpness is not to your taste, use lemon juice or a neutral oil instead. Just know that mustard oil adds a pungent edge that is typical of North Indian tandoori marinades.
Turning the Heat Up or Down
Kashmiri chilli powder is picked for its deep red colour and fairly mild heat. To make the skewers hotter, mix in some regular chilli powder or a pinch of cayenne next to it. Garam masala and kasuri methi bring warmth and aroma, not heat, so you can add more of them without the dish getting much spicier. Another easy route is to leave the marinade alone and let people adjust their own plate, with an extra-hot green chutney on the side or thin slices of fresh chilli scattered over the finished skewers.
Where Cooks Often Slip
A frequent error is putting paneer on the grill straight from the fridge. Cold paneer can tighten up and turn rubbery before it chars, so let the skewers sit out for about 15 minutes first. Another is cooking over weak heat, which dries the paneer out long before any real char appears; this dish needs strong heat and a short cooking time. A third is leaving the paneer in the marinade for too many hours, which makes it mealy instead of tender.
Keeping and Warming Up Leftovers
To keep it: You can keep the marinated paneer and vegetables in the fridge, off the skewers, for up to a day before grilling. Cooked paneer tikka lasts up to 2 days refrigerated, but it is best fresh, because paneer firms up when chilled and can be a bit rubbery once reheated.
To warm it up: Warm leftovers in a hot oven or air fryer for 4 to 5 minutes, or briefly in a hot pan, which brings back some of the char and heat without drying the paneer further. Try not to microwave them for long, since that makes paneer tough.
Kitchen Safety Note
Paneer is already a cooked dairy product, so there is no undercooking worry of the kind you have with raw meat. What matters is ordinary dairy care. Keep the paneer in the fridge until shortly before you marinate it, and do not let the yogurt marinade stand at room temperature for long periods. Wash the peppers and onion well before cutting them for the skewers.
