Wash and hull the strawberries, then cut them into thin slices.
Combine the sugar and lemon juice in a saucepan over medium heat, stirring until the sugar dissolves and the mixture begins to simmer.
Add the sliced strawberries to the saucepan, stirring gently to coat them with the syrup. Cook for about 3-5 minutes until the strawberries soften slightly and release their juices, but still hold some shape.
Reduce the heat to low and simmer for an additional 3-4 minutes, allowing the mixture to thicken slightly and the flavors to meld. Remove from heat once the syrup has glossy sheen and reaches a thick but pourable consistency.
Allow the strawberry topping to cool slightly before spooning over the cheesecake. Serve warm or at room temperature for best flavor and appearance.
