01 - In a large bowl, combine ground beef, minced garlic, grated onion, parsley, cumin, coriander, smoked paprika, chili flakes, salt, and pepper. Mix until just combined—do not overwork the meat.
02 - Divide the mixture into 8 equal portions. Shape each into a thick, oval patty. Gently flatten with your palm to about ¾ inch thickness for the classic smashed kebab shape.
03 - Squeeze excess moisture from the grated cucumber. In a separate bowl, mix together the Greek yogurt, drained cucumber, dill, lemon juice, minced garlic, salt, and pepper. Refrigerate until ready to serve.
04 - Heat olive oil in a large skillet or grill pan over medium-high heat. Add the kebabs and cook 4–5 minutes per side until deeply browned and cooked through to an internal temperature of 160°F.
05 - Serve the hot kebabs with generous dollops of cucumber yogurt sauce, sliced red onion, flatbreads or rice, and fresh herbs.
