Prepare the Crust: Preheat oven to 350°F (175°C).Combine graham cracker crumbs, melted butter, and sugar in a bowl.Press the mixture evenly into the bottom of a 9-inch springform pan.Bake for 8-10 minutes, then let it cool.
Blend the Cottage Cheese: In a food processor or blender, blend the cottage cheese until smooth.
Make the Filling: In a large mixing bowl, combine the blended cottage cheese, Greek yogurt, sugar, eggs, cornstarch, vanilla extract, and lemon zest. Mix until smooth.
Assemble the Cheesecake: Pour the filling over the cooled crust and spread evenly.Tap the pan gently to release air bubbles.
Bake the Cheesecake: Place the cheesecake in the oven and bake for 50-60 minutes, or until the edges are set but the center is slightly jiggly.Turn off the oven and let the cheesecake cool inside for 1 hour with the door slightly ajar.
Chill the Cheesecake: Refrigerate for at least 4 hours or overnight for the best results.
Serve: Remove from the springform pan, slice, and garnish with fresh fruit, whipped cream, or honey.
