If you’re looking for a showstopping and mouthwatering dessert to impress dinner guests, look no further than this lemon meringue cheesecake recipe.
Arrange racks in upper and lower thirds of oven; preheat to 350°. Grease a 9" springform pan with cooking spray.
In the large bowl of a stand mixer fitted with the paddle attachment, beat cream cheese, granulated sugar, sour cream, cornstarch, lemon zest, vanilla, and salt on medium speed until smooth, about 1 minute (a few lumps of cream cheese are fine). With mixer on low speed, beat in eggs until fully combined, about 1 minute. Pour filling into crust.
Once cheesecake has cooled 30 minutes, pour water into a medium saucepan to a depth of 1" to 2". Bring to a simmer over medium-high heat.
In a large, very clean bowl of stand mixer fitted with the whisk attachment, beat egg whites, cream of tartar, and salt on medium-high speed until soft peaks form, 1 to 2 minutes. Gradually add granulated sugar, 1 tablespoon at a time, and beat until incorporated. Increase mixer speed to high and beat until meringue is glossy and stiff peaks form, about 2 minutes.
