Dessert doesn't get any better than this recipe for Lemon Blueberry Pie. Swirled with scratch-made blueberry sauce, this bright and creamy lemon pie sits atop a buttery shortbread crust. Citrusy and sweet, this pie is a summertime classic.
Add cornstarch and lemon juice to a small bowl. Stir until combined and cornstarch has dissolved.
Pour cornstarch mixture into a small saucepan over medium heat. Add blueberries and sugar then stir gently while mashing blueberries with the backside of a spoon until sauce thickens--approximately 5 minutes.
Strain blueberry sauce through a fine mesh sieve then cool sauce to room temperature. (Note: only the strained sauce will be used for the swirl, but feel free to garnish pie slices with the blueberries remaining in the strainer.)
Shortbread Crust
Preheat oven to 350 degrees.
Pulse crust ingredients in a food processor until a soft dough forms.
Using your fingers, press shortbread dough into the bottom and up the sides of a 9-inch pie plate until evenly packed.
Bake for 15 minutes or until lightly golden brown then remove from oven to add lemon filling.
Lemon Filling
Combine sweetened condensed milk, lemon juice, lemon zest and egg yolks in a large mixing bowl then whisk until combined.
Pour lemon filling onto warm shortbread crust.
Drop small dollops of blueberry sauce onto lemon filling and swirl gently with a chopstick or butter knife.
Bake for 15 to 18 minutes, until center is just set and no longer jiggly. Do not overbake.
Place pie plate on a wire rack and cool to room temperature.
Chill in the refrigerator for a minimum of 2 hours before serving. (Mine chilled overnight.)
For best results, allow pie to come to room temperature for 30 minutes before slicing. This allows the shortbread crust time to soften.
Store leftovers covered in the refrigerator up to 5 days.
