Preheat your oven to 325°F (160°C).
In a bowl, mix graham cracker crumbs, 1/2 cup sugar, and melted butter until combined.
Press the mixture into the bottom of a 9-inch springform pan.
In a large mixing bowl, beat cream cheese until smooth and creamy.
Gradually add in 1 cup sugar and vanilla extract, mixing well.
Add the eggs one at a time, mixing on low speed after each addition.
Stir in sour cream and lemon juice until well combined.
Pour the cream cheese mixture over the crust in the springform pan.
Bake for 60 minutes or until the center is set but still slightly jiggly.
Turn off the oven, crack the door, and let the cheesecake cool in the oven for an hour.
Refrigerate for at least 4 hours before serving.
