Step 1: Prepare the Crust
- Preheat the Oven: Preheat your oven to 325°F (165°C).
- Combine Crust Ingredients: In a medium bowl, mix the graham cracker crumbs, sugar, and melted butter until well combined and moist.
- Press into Pan: Press the mixture firmly into the bottom of a 9-inch springform pan, creating an even layer.
- Bake the Crust: Bake for 8–10 minutes until lightly golden, then set aside to cool.
Step 2: Make the Cheesecake Filling
- Beat the Cream Cheese and Sugar: In a large mixing bowl, beat the softened cream cheese and sugar on medium speed until smooth and creamy.
- Add the Eggs: Add the eggs one at a time, mixing on low speed just until each one is incorporated.
- Add Sour Cream, Vanilla, and Lemon Zest: Stir in the sour cream, vanilla extract, and lemon zest until well mixed.
- Pour Over the Crust: Pour the cheesecake filling over the cooled crust and smooth the top with a spatula.
Step 3: Bake the Cheesecake
- Prepare a Water Bath: Place the springform pan in a larger baking pan and fill the outer pan with hot water, reaching halfway up the sides of the springform pan.
- Bake: Bake at 325°F (165°C) for 60–70 minutes. The cheesecake should be set around the edges but slightly jiggly in the center.
- Cool Gradually: Turn off the oven, crack the door open slightly, and let the cheesecake cool inside for 1 hour to prevent cracks.
- Refrigerate: Remove the cheesecake from the oven, let it cool to room temperature, and then cover and refrigerate for at least 4 hours or overnight.
Step 4: Make the Blueberry Topping
- Cook the Blueberries: In a medium saucepan, combine the blueberries, sugar, and lemon juice. Cook over medium heat, stirring occasionally until the blueberries begin to release juice.
- Thicken the Sauce: In a small bowl, mix the cornstarch and water to form a slurry, then add it to the blueberry mixture. Simmer until the sauce thickens, about 2–3 minutes.
- Cool the Topping: Remove from heat and let the blueberry topping cool to room temperature.
Step 5: Assemble and Serve
- Add the Blueberry Topping: Once the cheesecake is fully chilled, pour the blueberry topping over the top, spreading it evenly.
- Garnish (Optional): Add a sprinkle of lemon zest or a few fresh blueberries for decoration.
Tips for the Perfect Blueberry Cheesecake
- Room Temperature Ingredients: Use room temperature cream cheese, eggs, and sour cream for a smooth filling.
- Avoid Over-Mixing: Mix ingredients just until incorporated to avoid cracks in the cheesecake.
- Water Bath: This prevents the cheesecake from drying out and keeps it creamy.
