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, then gently flatten with your palm to about ¾ inch thickness to achieve the characteristic smashed shape.
03 - 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.
04 - While the kebabs cook, squeeze excess moisture from the grated cucumber. Combine with Greek yogurt, dill, lemon juice, minced garlic, salt, and pepper. Stir well and chill until ready to serve.
05 - Arrange the hot kebabs on a platter with generous dollops of cucumber yogurt sauce, sliced red onion, flatbreads or rice, and a scattering of fresh herbs.
