01 - In a large bowl, combine the ground beef, minced garlic, grated onion, parsley, cumin, coriander, smoked paprika, chili flakes, salt, and pepper. Gently mix with your hands until just incorporated — avoid overworking the meat to keep the texture tender.
02 - Divide the seasoned beef into 8 equal portions. Roll each into a thick oval patty, then press flat between your palms to about ¾ inch thickness, creating the signature smashed shape.
03 - Heat olive oil in a large skillet or grill pan over medium-high heat. Arrange the kebabs in the pan without crowding and sear for 4–5 minutes per side until deeply browned and cooked through to an internal temperature of 160°F.
04 - While the kebabs cook, squeeze the grated cucumber firmly to remove excess moisture. Combine it in a small bowl with the Greek yogurt, dill, lemon juice, minced garlic, salt, and pepper. Stir well and refrigerate until ready to serve.
05 - Arrange the hot kebabs on a platter with generous dollops of cucumber yogurt sauce alongside. Garnish with sliced red onion, fresh herbs, and serve with warm flatbreads or rice if desired.
