Preheat the oven to 325°F (163°C). Grease a 9-inch springform pan.
In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined. Press the mixture into the bottom of the springform pan.
Bake the crust for 10 minutes, then remove and let cool while preparing the filling.
In a large mixing bowl, beat the softened cream cheese and sugar until smooth.
Add eggs one at a time, mixing after each addition. Stir in vanilla extract and sour cream until well combined.
Pour the filling over the cooled crust and smooth the top.
Bake for 50–60 minutes, or until the center is slightly jiggly but set. Turn off the oven and let the cheesecake cool inside with the door slightly open for 1 hour.
Refrigerate for at least 4 hours (preferably overnight) before adding the topping.
In a saucepan over medium heat, combine sliced strawberries, sugar, and lemon juice. Cook for 5 minutes until strawberries soften and release juices.
Remove from heat and let the strawberry topping cool completely.
Spread the cooled strawberry topping over the chilled cheesecake before serving.
Notes
For a firmer texture, refrigerate the cheesecake overnight before adding the strawberry topping. You can also blend the strawberry topping for a smoother sauce.
