In a medium bowl, combine graham cracker crumbs and sugar. Stir in melted butter until well combined.
Press the crumb mixture firmly into the bottom of a 9-inch springform pan.
Bake the crust for 8-10 minutes, then remove from oven and let cool slightly.
In a large bowl, beat cream cheese and sugar until smooth and creamy.
Add eggs one at a time, beating well after each addition.
Stir in sour cream, vanilla extract, and lemon zest until just combined.
Pour the filling over the prepared crust.
Bake for 50-60 minutes, or until the center is almost set but still slightly jiggly.
Turn off the oven, crack the door open, and let the cheesecake cool in the oven for 1 hour.
Remove from oven and let cool completely on a wire rack. Then, cover and refrigerate for at least 4 hours, or preferably overnight.
Serve chilled. Top with fresh berries or fruit compote if desired.
Notes
For best results, ensure all ingredients for the filling are at room temperature before mixing. This helps create a smoother texture and prevents lumps.
