Chef John's Cheesecake Flan

Preheat oven to 325°F (160°C). Lightly coat the insides of four 5 1/2-ounce ramekins with vegetable oil to prevent sticking. (5 minutes)

In a medium skillet over medium heat, combine 1/2 cup plus 2 tablespoons of granulated sugar. Cook, without stirring, until the sugar melts and caramelizes into a deep amber color. Swirl the pan gently to ensure even caramelization. Quickly pour the caramel into the prepared ramekins, coating the bottoms evenly. Place the ramekins inside a large baking dish. (10 minutes)

In a mixing bowl, whisk together the softened cream cheese, beaten eggs, Parmesan cheese, vanilla extract, and salt until the mixture is smooth and homogeneous. Ensure there are no lumps for a silky custard. (5 minutes)

In a small saucepan, heat 1 cup of milk until it is almost simmering. Stir in 1/2 cup granulated sugar until completely dissolved. Gradually pour the warm milk mixture into the cream cheese mixture, whisking continuously until well combined, creating a smooth custard base. (5 minutes)

Carefully spoon the custard mixture into the caramel-lined ramekins, filling them almost to the top. Gently pour hot water into the baking dish to create a water bath, reaching halfway up the sides of the ramekins. This ensures even cooking and a creamy texture. (5 minutes)

Bake in the preheated oven for 45 to 60 minutes, or until the custard is just barely set. The custard should jiggle slightly as one mass when gently shaken. Remove the ramekins from the water bath and let them cool to room temperature for about 20 minutes. (60 minutes)

In a small bowl, combine the graham cracker crumbs and melted butter. Mix well until the crumbs are evenly moistened. Sprinkle the crumb mixture evenly over the top of each flan. Refrigerate for at least 2 hours, or until fully chilled and set. (150 minutes)

Once chilled, run a thin knife along the edges of the flans to loosen them from the ramekins. Invert each flan onto a serving plate. Drizzle any remaining caramel from the ramekins over the top for added flavor and visual appeal. Serve immediately and enjoy this delightful dessert. (5 minutes)
