Preheat your oven to 400°F. Cut each peach into 4–6 wedges and place them in a baking dish or sheet pan.
6 medium to large peaches
Sprinkle the brown sugar, cinnamon, and salt evenly over the top and give everything a gentle toss to coat.
¼ cup brown sugar, ¼ teaspoon cinnamon, dash of table salt
Roast for 10–12 minutes, until the peaches are just tender and the sugar has started to caramelize around the edges. Let them cool before using.
Graham Cracker Crust:
Lower your oven to 350°F. Spray a 9-inch springform pan with cooking spray and wrap the outside bottom in foil to prevent leaks.
In a medium bowl, combine the graham cracker crumbs and granulated sugar. Add the melted butter and mix until well combined.
2 ½ cups fine graham cracker crumbs, ⅓ cup granulated sugar, 10 tablespoons unsalted butter melted
Press the mixture into the bottom and halfway up the sides of the pan using the bottom of a flat cup or your hand. Bake for 14 minutes.
Cheesecake Filling:
Lower your oven to 325°F. Pour water into a sheet pan or roasting pan, filling it a little less than halfway. Place it on the lowest rack in the oven so it can start to heat up while you make the cheesecake.
In a large mixing bowl, beat the room temperature cream cheese on medium speed with a handheld or stand mixer until smooth and creamy.
32 ounces full-fat cream cheese 4 blocks room temperature
With the mixer on low, gradually add the brown sugar and beat until well combined.
¾ cup brown sugar packed
Add the egg yolk and whole eggs all at once and mix on low just until incorporated. Scrape down the bottom and sides of the bowl with a rubber spatula.
1 large egg yolk room temperature, 2 large whole eggs room temperature
Gently fold in the sour cream, vanilla extract, cornstarch, and cinnamon with a rubber spatula until smooth. Its okay if there are a few lumps,Be careful not to overmix.
1 teaspoon vanilla extract, ¼ cup sour cream, ¼ cup cornstarch, 3 teaspoons ground cinnamon
Assembling the Cheesecake:
Pour half of the cheesecake filling into the baked crust and spread evenly.
Arrange half of the roasted peach slices on top and spread evenly with the back of a spoon.
Pour the remaining cheesecake batter over the peaches and spread into an even layer.
Place the cheesecake on a separate sheet pan and set it in the oven above the pan of water. Bake for 70–75 minutes, until the edges are set and the center has a slight jiggle. If the center is still very loose, bake for an additional 5 minutes.
Once the cheesecake has just a slight wobble, turn off the oven and prop the door open for one hour.
Let the cheesecake cool to room temperature, then refrigerate for at least 4 hours to set.
Serving:
Arrange the remaining roasted peach wedges over the top of the cheesecake. Serve cold and enjoy!
