**Preheat the oven** to 325°F (165°C). Line a springform pan with parchment paper and grease the sides.
**Make the crust:** Mix graham cracker crumbs, sugar, and melted butter. Press into the bottom of the springform pan. Bake for 10 minutes, then let cool.
**Prepare the filling:** In a large bowl, beat the cream cheese until smooth. Gradually add sugar and mix well.
**Add wet ingredients:** Beat in eggs one at a time, then mix in sour cream, vanilla extract, lemon juice, and lemon zest.
**Fold in blueberries** gently to avoid breaking them.
**Bake:** Pour the batter over the crust. Place a water bath (oven-safe dish with hot water) on the lower rack of the oven to prevent cracks. Bake for 55-60 minutes until the edges are set but the center is slightly jiggly.
**Cool slowly:** Turn off the oven and let the cheesecake cool inside with the door slightly open for 1 hour. Then, remove and cool completely on a wire rack.
**Chill for at least 4 hours** (preferably overnight) before serving.
**Top with blueberry preserves or fresh blueberries** and whipped cream if desired. Slice and enjoy!
