Mix 16 ounces regular cream cheese, softened, in a large bowl until very smooth. You can use a handheld mixer or a wire whisk. Mixing the cheese by hand should not be a problem if the cheese is at room temperature. If using an electric mixer, use it only for this part and at the lowest speed. We don't want to incorporate air into the batter.
Gradually add ½ cup + 2 tablespoons granulated sugar and beat until it's very well incorporated.
Add 3 eggs all together, mixing until incorporated and scraping down the sides of the bowl to make sure all the ingredients are well mixed. Don't be tempted to beat.
Add ½ teaspoon vanilla extract or vanilla paste, ½ teaspoon lemon zest and ¼ cup sour cream, stirring to incorporate.
Add 1 ½ cups blueberries to the cream cheese mixture and stir with a spatula. Don't crush the berries. Pour the batter into the prepared pan.
Bake the cheesecake for about 30 to 35 minutes, until the center jiggles slightly and the sides are a little puffed. The time can vary depending on your oven.
Remove from the oven, let it cool on a wire rack for 15 minutes, and carefully run a smooth-bladed knife around the sides of the pan to loosen up any batter that might be stuck. If it's too tender, let it cool a little longer. It will help prevent cracks as the cheesecake cools and shrinks.
Cool completely to room temperature in the pan on a wire rack, cover it with plastic wrap (still in the pan), and refrigerate for at least 6 to 8 hours before cutting and serving. I chill it for 1 or 2 days for the creamiest consistency before removing it from the pan.
