Combine ground beef, minced onion, garlic, parsley, and mint in a large bowl. The key here is mincing everything finely so each bite gets balanced flavor. Add all your spices - cumin, coriander, cinnamon, paprika, salt, and pepper.

Pour in the beaten egg and breadcrumbs, then gently mix everything with your hands. Don't overmix - you want tender koftas, not tough ones. The mixture should hold together when squeezed but still feel light. If it seems too wet, add a tablespoon more breadcrumbs.

With slightly damp hands, form the mixture into 12 oval-shaped patties, about 3 inches long. The dampness prevents sticking and helps create smooth surfaces. Place them on a plate and let them rest for 10 minutes.

Heat your grill pan or outdoor grill to medium-high heat. Cook the koftas for 5-6 minutes per side, turning once. You'll know they're ready when they develop a beautiful golden-brown crust and feel firm to the touch. The internal temperature should reach 160°F for food safety.
