Preheat the oven to 325°F and line a muffin tin with paper liners.
In a medium bowl, combine graham cracker crumbs, 3 tablespoons of sugar, and melted butter. Mix until well combined.
Press about 1 tablespoon of the mixture into the bottom of each muffin liner to form the crust.
In a large mixing bowl, beat the softened cream cheese with 1/2 cup sugar and vanilla extract until smooth and creamy.
Add the eggs one at a time, mixing well after each addition.
Stir in the lemon juice and lemon zest until fully incorporated.
Gently fold in the blueberries.
Pour the cheesecake mixture over the crusts in the muffin tin, filling each liner about 3/4 full.
Bake for 18-20 minutes, or until the edges are set but the centers are slightly jiggly.
Remove from the oven and let cool at room temperature for 30 minutes, then refrigerate for at least 2 hours before serving.
