01 - In a large bowl, combine the ground beef, minced garlic, grated onion, chopped parsley, cumin, coriander, smoked paprika, chili flakes, kosher salt, and black pepper. Mix gently until just incorporated—avoid overworking the meat to keep the kebabs tender.
02 - Divide the mixture into 8 equal portions. Shape each into a thick oval patty, then gently flatten with your palm to about ¾ inch thickness, creating the signature smashed profile.
03 - Heat olive oil in a large skillet or grill pan over medium-high heat. Place the kebabs in the pan and cook for 4 to 5 minutes per side until deeply browned and cooked through to an internal temperature of 160°F.
04 - While the kebabs cook, squeeze excess moisture from the grated cucumber. In a small bowl, combine the cucumber with Greek yogurt, chopped dill, lemon juice, minced garlic, salt, and pepper. Stir until smooth and refrigerate until ready to serve.
05 - Arrange the hot kebabs on a platter with generous dollops of cucumber yogurt sauce, sliced red onion, warm flatbreads or rice, and scattered fresh herbs. Serve immediately.
