01 - Preheat oven to 340°F (170°C). Grease and line a 9-inch springform pan.
02 - Layer 6 sheets of phyllo dough in the bottom of the pan, brushing each sheet with melted butter. Evenly sprinkle half of the pistachios, walnuts, sugar, and cinnamon mixture over the layered dough.
03 - Layer the remaining 6 phyllo sheets atop, brushing each with melted butter. Spread the remaining nut mixture evenly, pressing gently. Bake crust for 10 minutes, then cool slightly.
04 - Beat cream cheese until smooth using an electric mixer. Add Greek yogurt, sugar, and lemon zest, mixing until combined. Incorporate eggs one at a time, beating after each addition, then stir in vanilla extract.
05 - Pour the filling over the cooled crust. Tap the pan gently to release any air bubbles. Bake for 45 minutes at 340°F (170°C) or until center is set but slightly wobbly.
06 - Turn off the oven, leave the oven door ajar, and let the cheesecake cool inside for 1 hour.
07 - Transfer cheesecake to the refrigerator and chill for at least 3 hours or overnight until fully set.
08 - In a small saucepan, combine honey, water, sugar, and lemon juice. Heat gently until sugar dissolves, then simmer for 3–4 minutes and cool to room temperature.
09 - Pour cooled syrup over the chilled cheesecake and sprinkle with chopped pistachios before serving.
