Preheat the oven to 410°F (210°C). Grease a 9-inch (23 cm) springform pan and line it with parchment paper, leaving an overhang for easy removal and the signature rustic look.
In a large bowl, cream the cream cheese and sugar using a hand or stand mixer on medium speed until smooth and fluffy (2-3 minutes).
Add the pistachio paste and mix until fully incorporated and smooth.
Beat in the eggs one at a time, ensuring each is well mixed before adding the next. Scrape down the bowl as needed.
Pour in the heavy cream, vanilla bean paste, and salt. Mix until the batter is smooth and creamy.
Sift in the flour and gently mix on low speed until just combined. Do not overmix.
Pour the batter into the prepared pan. The batter will be loose but will firm up as it bakes.
Bake for 45-60 minutes, or until the top is deep golden brown and the center is slightly jiggly. A darker top is normal for this cheesecake.
Cool the cheesecake in the pan at room temperature. It will deflate slightly as it cools.
Refrigerate for at least 4 hours or overnight to allow the cheesecake to fully set.
