Preheat the oven to 325°F (163°C) and grease a 9-inch springform pan with butter or cooking spray.
In a medium bowl, combine graham cracker crumbs, ground pistachios, 0.25 cup sugar, and melted butter until the mixture resembles wet sand.
Press the mixture firmly into the bottom and 1 inch up the sides of the prepared springform pan. Bake for 10 minutes, then remove and let cool completely.
In a large mixing bowl, beat the cream cheese and 1 cup sugar on medium speed until smooth and aerated, approximately 3 minutes.
Add the sour cream, pistachio paste, and vanilla extract, mixing until fully incorporated.
Reduce mixer speed to low and add eggs one at a time, mixing just until the yolk disappears to avoid over-incorporating air.
Pour the cheesecake batter over the cooled crust and smooth the top with a spatula.
Bake for 55 to 65 minutes, or until the edges are set and the center has a slight wobble when the pan is gently shaken.
Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour to prevent cracking.
Remove from the oven and refrigerate for at least 6 hours, preferably overnight.
Before serving, spread the cherry pie filling evenly over the top and garnish with chopped pistachios.
