In a medium saucepan, combine quartered fresh strawberries, 2 tablespoons of granulated sugar, lemon juice, water, and corn starch. Cook over medium heat for about 5-7 minutes, stirring gently until the mixture thickens and bubbles. Once thickened, remove from heat and let it cool to room temperature while you prepare the cheesecake filling.

Preheat your oven to 350°F (175°C). In a mixing bowl, combine 175g of graham cracker crumbs, ¾ cup sugar, and ¼ teaspoon kosher salt. Stir in 5 tablespoons of melted unsalted butter until the mixture resembles wet sand. Press this mixture firmly into the bottom of a springform pan, creating an even layer, then bake for 8-10 minutes until golden and fragrant. Allow the crust to cool.

In a large mixing bowl, beat 24 ounces of softened cream cheese with an electric mixer until smooth and creamy. Gradually add ¾ cup of granulated sugar, ¾ cup sour cream, 1 tablespoon of vanilla extract, and ¼ teaspoon salt, mixing until well incorporated. Add 2 large eggs one at a time, blending well after each addition but ensuring not to overmix to prevent cracks in your Strawberry Swirl Cheesecake.

Carefully pour half of the cheesecake filling into the cooled crust, spreading it evenly. Spoon half of the cooled strawberry mixture over this layer, swirling gently with a knife for a marbled effect. Add the remaining cheesecake filling and top with the rest of the strawberry swirl. Use the knife again to create a beautiful design, being careful not to mix too thoroughly.

Place the springform pan in the preheated oven and bake the Strawberry Swirl Cheesecake for approximately 50-60 minutes. The cheesecake is done when the edges are set, but the center still has a slight jiggle. Remove from the oven, and let it cool at room temperature for about 1 hour, which will help prevent cracking before chilling.

After cooling, refrigerate the cheesecake for at least 7 hours, or overnight, to ensure it sets properly. When ready to serve, carefully remove the cheesecake from the springform pan. Slice into generous pieces and top with additional fresh strawberries or whipped cream if desired to enhance the delightful presentation of your Strawberry Swirl Cheesecake.
