For the Lemon Filling

  • 1 cup freshly squeezed lemon juice The star ingredient that gives it that classic refreshing tang.
  • 2 tbsp lemon zest Amplifies the citrusy flavor profile.
  • 1 1/2 cups granulated sugar Sweetens the lemon filling.
  • 4 large eggs Helps to set the filling.
  • 1 tbsp cornstarch Thickens the lemon curd for the filling.

  • 1/2 tsp cream of tartar Stabilizes the meringue.
  • 3/4 cup granulated sugar Sweetens the meringue.
  • 1/2 tsp vanilla extract Adds a gentle background note in the meringue.

Instructions

Prepare the Crust

  • Preheat your oven to 175°C (350°F). Line an 8×8 inch baking pan with parchment paper.
  • In a bowl, beat the softened butter and powdered sugar together until creamy.
  • Add the vanilla extract and mix in the flour and salt. Press this buttery mixture into the lined pan.
  • Bake for 18-20 minutes, or until the edges are golden.

Make the Lemon Filling

  • In another bowl, whisk together the eggs, granulated sugar, freshly squeezed lemon juice, lemon zest, flour, and cornstarch until the mixture is smooth and well combined.
  • Pour the lemon filling over the baked crust and return the pan to the oven.
  • Bake for an additional 25 minutes, or until just set and slightly jiggly in the center.

Prepare the Meringue

  • Once the lemon layer has cooled slightly, beat the egg whites with cream of tartar in a clean bowl until soft peaks form.
  • Gradually add the sugar while continuing to beat until stiff, glossy peaks form.
  • Blend in the vanilla extract to finish the meringue.

Assemble and Bake

  • Spread the meringue over the cooled lemon layer, using a spoon to create decorative swirls on top.
  • You can either lightly torch the meringue until golden, or place it under the broiler for 1-2 minutes for a similar effect.

Cool and Serve

  • Allow the tart to chill for at least 1 hour before slicing into bars.
  • For the best texture and flavor, serve these delightful squares cold.

Notes

Baking Time: Keep an eye on your crust and lemon filling as baking times may vary depending on your oven. Aim for a golden crust and firm but slightly jiggly filling to avoid a runny texture. Meringue Secrets: Ensure your mixing bowl and beaters are completely clean for the meringue. Any grease can prevent the egg whites from whipping up properly. Flavor Variations: Experiment with other citruses, like limes or oranges, for a unique twist on this classic dessert. Topping Ideas: Consider adding fresh berries or a dollop of whipped cream on top for extra flair.
