Step 1: Preheat the Oven

• Preheat your oven to 325°F (160°C).
• Prepare a 9-inch springform pan by greasing the bottom and sides.

Step 2: Make the Crust

• In a mixing bowl, combine the pistachio crumbs, sugar, and melted butter. Mix until well combined.
• Press the mixture firmly into the bottom of the prepared springform pan to form an even layer.

Step 3: Prepare the Filling

• In a large mixing bowl, beat the softened cream cheese and sugar together until smooth and creamy, about 3-4 minutes.
• Add the vanilla extract and mix until combined.
• Add the eggs one at a time, mixing well after each addition.
• Gently fold in the heavy cream, chopped pistachios, and pistachio paste (if using) until just combined.

Step 4: Bake the Cheesecake

• Pour the cheesecake filling over the prepared crust, smoothing the top with a spatula.
• Bake for 55-60 minutes, or until the edges are set and the center is slightly jiggly.

Step 5: Cool and Chill

• Turn off the oven and leave the cheesecake inside with the door ajar for 1 hour to cool gradually.
• Remove from the oven and let it cool to room temperature. Then refrigerate for at least 3 hours or overnight for the best flavor and texture.

Step 6: Serve

• Once chilled, carefully remove the cheesecake from the springform pan.
• Garnish with whipped cream, chopped pistachios, and fresh mint leaves, if desired.
