Tangy lemon cream meets a jammy fresh blueberry topping in this luscious, crowd-pleasing pie. A buttery graham cracker crust anchors a silky no-bake lemon cream cheese filling for the ultimate sweet-tart dessert.
Heat oven to 350°F. Lightly grease a 9-inch pie plate.
Make the crust: In a bowl, combine graham cracker crumbs, 0.25 cup sugar, and melted butter until evenly moistened. Press firmly into the bottom and up the sides of the pie plate.
Bake the crust for 8 to 10 minutes until lightly golden. Cool completely on a rack.
Make the lemon cream filling: Beat softened cream cheese on medium speed until smooth and fluffy, about 2 minutes.
Slowly stream in the sweetened condensed milk, beating until silky with no lumps, scraping the bowl as needed.
Mix in lemon juice, 1 tbsp lemon zest, vanilla, and salt until fully combined. Spread filling into the cooled crust. Chill at least 2 hours to set.
Make the blueberry topping: In a saucepan whisk 0.5 cup water, 0.5 cup sugar, and cornstarch until smooth. Stir in 2 cups of the blueberries and 2 tbsp lemon juice.
Cook over medium heat, stirring, until thick, glossy, and many berries burst, 4 to 6 minutes. Remove from heat and fold in remaining 1 cup blueberries and 1 tsp lemon zest. Cool to room temperature.
Spoon cooled blueberry topping over the chilled lemon cream layer. Chill 30 minutes to set the topping.
Optional garnish: Whip heavy cream with powdered sugar and 0.5 tsp vanilla to soft peaks; dollop or pipe on slices. Serve cold. Store leftovers covered in the refrigerator up to 3 days.
Notes
For the brightest flavor, use fresh lemon juice and zest. If using frozen blueberries, do not thaw; cook directly from frozen and add an extra 1 tsp cornstarch if the topping seems thin.
