Ingredients
For the crust:
- 1 ½ cups all-purpose flour
- ½ cup unsalted butter, melted
- ¼ cup granulated sugar
- Pinch of salt
For the lemon filling:
- 1 cup granulated sugar
- 3 large eggs
- ½ cup fresh lemon juice
- 1 tablespoon lemon zest
- ¼ cup all-purpose flour
For the meringue topping:
- 3 egg whites
- ½ cup granulated sugar
- ½ teaspoon vanilla extract
- Pinch of salt
Preparing the Crust
Preheat the oven to 180°C (350°F). Line a rectangular baking pan with parchment paper for easy removal later.
In a mixing bowl, combine flour, sugar, salt, and melted butter. Stir until the mixture forms a soft dough. Press the dough evenly into the bottom of the prepared pan to form a firm crust layer.
Bake the crust for about 15 minutes, or until lightly golden. Remove from the oven and allow it to cool slightly while preparing the lemon filling.
The buttery base provides structure and a mild sweetness that balances the tart lemon layer. A well-baked crust ensures the bars hold their shape when sliced.
Making the Lemon Filling
In a medium bowl, whisk together eggs and sugar until smooth. Add lemon juice, lemon zest, and flour, and mix until fully combined. The filling should have a silky, pourable consistency.
Pour the lemon mixture over the warm crust and return the pan to the oven. Bake for 18–20 minutes, or until the lemon layer is set but still slightly soft in the center.
Fresh lemon juice gives these lemon bars their signature flavor. The natural acidity creates a refreshing contrast to the sweetness of the crust and meringue topping.
Allow the lemon layer to cool before adding the meringue.
Preparing the Meringue Topping
In a clean mixing bowl, beat egg whites with a pinch of salt until soft peaks form. Gradually add sugar while continuing to beat until stiff, glossy peaks develop. Mix in the vanilla extract.
Spread the meringue over the cooled lemon layer, creating decorative peaks with a spoon or spatula.
Place the pan back into the oven for about 10 minutes, or until the meringue becomes lightly toasted and golden on top. Watch carefully to avoid over-browning.
The toasted meringue adds a light and airy texture that complements the creamy lemon filling beautifully.
Cooling and Serving
Allow the lemon meringue bars to cool completely at room temperature, then refrigerate for at least one hour before slicing. Chilling helps the layers set properly and makes cutting cleaner and easier.
Use a sharp knife to cut into squares or rectangles. Wipe the knife between cuts to keep the edges neat and defined.
These lemon dessert bars are best served slightly chilled, which enhances the refreshing citrus flavor and creamy texture.
Storage Tips
Store lemon meringue bars in an airtight container in the refrigerator for up to three days. Because of the meringue topping, freezing is not recommended, as it may lose its texture when thawed.
If preparing ahead of time, the crust and lemon filling can be baked earlier in the day, and the meringue can be added shortly before serving.
