Marinate the Meat:
In a large baking tray, mix the olive oil, pepper paste, milk, spices, and oregano into a smooth paste. Add the lamb and garlic, ensuring each piece is well-coated. Cover and refrigerate for 1-4 hours.
Prepare the Oven:
Preheat your oven to 180°C (fan) or 200°C.
Arrange the Ingredients:
Season the lamb with salt and pepper, then place it in the center of the tray. Arrange the vegetables side by side ("yanyana") around the meat in sections. Brush the vegetables with olive oil, nestle in bay leaves, and sprinkle with the remaining seasonings. Cover with parchment paper and foil.
Cook to Perfection:
Bake covered for 1 hour. Increase the oven temperature to 210°C (fan) or 230°C, remove the foil and parchment, baste the vegetables with pan juices, and cook uncovered for an additional 20-25 minutes until caramelized.
Serve:
Serve hot with fresh bread, a crisp salad, and a dollop of yogurt for the ultimate Turkish experience.
