Add all of the ingredients into a large bowl and thoroughly mix everything together until completely combined.: The moment you combine the ground sirloin , ground lamb , herbs, and spices you will smell an immediate wave of warm aromatics, the cumin and cinnamon rising first. Use your hands to fold and press the mixture, feeling its texture change from loose to cohesive, which means the proteins are interacting with the seasonings. Mixing by hand also helps distribute the garlic and onion so there are no concentrated pockets of flavor. A common mistake is overworking the meat, which can make the final kebabs dense; aim for even distribution without compacting too aggressively. If the mixture feels too wet, a brief chill will firm it and make shaping easier.
Place in the refrigerator covered for at least 30 minutes or up to overnight.: Chilling the mixture solidifies the fats and allows the flavors to meld, giving you a smoother texture and easier shaping. When you open the bowl after chilling you ll notice the smell deepened and the mixture will hold its shape better under pressure. I usually cover it loosely so moisture does not collect on top. A pitfall is skipping this rest, which often leads to meat that slips off skewers or falls apart while cooking. If you re short on time, the minimum 30 minutes will still help, but overnight makes the best flavor development.
Remove the meat mixture and take out a large chunk and form it into a tight cylinder.: When you shape a portion, press firmly and roll between your palms to expel air pockets, creating a dense, even cylinder. The feel should be springy but cohesive, not crumbly or soupy. You will notice how the mixture glues together as the minced herbs and onion help bind it. Avoid leaving large gaps or uneven thickness, which cause uneven cooking. A frequent slip is making cylinders too thin, which leads to dryness, so aim for a substantial but manageable size.
Skewer the meat cylinder and then press and pull it to fit a majority of the skewer. Repeat until all of the meat has been used.: Thread the cylinder onto the skewer longways, then use your hands to press and shape the meat along the metal so it clings evenly. This pressing and pulling motion ensures good contact with the skewer and creates the classic elongated kofta shape. You should hear a slight squish as the meat forms around the metal, and visually it should look smooth and snug. Be careful not to leave gaps between the meat and skewer, otherwise the kebab may slide during cooking. If pieces slip, return them to the fridge for a quick chill and try again.
Preheat your grill to 450° to 550° F or a griddle to medium-high heat.: Keep a consistent portion size so all kebabs cook uniformly, arranging shaped skewers on a tray as you go. The tray will show a row of similar cylinders, and this uniformity helps you time grilling perfectly. I like to alternate a quick chill between batches if my hands warm the meat too much while shaping. A common error is making the first few kebabs larger than the rest, which means you ll have mismatched cook times; use a measuring scoop if you need consistency.
Place the kofta kebabs right onto your grill or griddle and cook for 3-4 minutes or until very browned and cooked throughout.: Preheating is vital for a quick sear that locks in juices and creates those appealing char marks. When the grill reaches temperature you will see the grates shimmer and smell a faint toasty aroma, a signal that the surface is ready. If the surface is not hot enough, the meat will stick and weep fat rather than sear. Avoid opening the grill repeatedly while heating, as this drops the temperature. On a griddle you want a steady medium-high heat that sizzles on contact without burning the meat immediately.
Remove and serve.: As the skewers hit the hot surface, you should hear a lively sizzle and smell the spices blooming. The outside will quickly brown and develop caramelized edges while the inside stays juicy. Use tongs to rotate gently for even browning on all sides. A telltale cue is when the meat releases easily from the grates, that s the moment to flip or rotate. Overcooking will dry them out, so monitor the color more than the clock, and consider a quick temperature check if you re unsure. If the exterior darkens too fast while the interior is still cold, move the skewers to a slightly cooler zone to finish cooking more gently.
Remove and serve: Right after removing the kebabs you ll notice the aromatic steam rising and the charred edges offering a pleasant textural contrast. Let them rest briefly so juices redistribute, then serve hot from the skewer or slide onto a platter. Resting for a few minutes keeps the interior juicy and prevents all the juices from spilling out the moment you slice or bite. A mistake I see is serving them immediately without a short rest, which leads to a dryer mouthfeel and lost flavor. Present with simple accompaniments and enjoy the layered spice notes that developed during cooking.
