Table of Contents
Ingredients
For the Buttery Shortbread Crust:
- 1 cup (2 sticks) unsalted butter, softened to room temperature
- 1/2 cup granulated sugar
- 2 cups all-purpose flour
- 1/4 teaspoon salt
For the Tangy Lemon Filling:
- 4 large eggs, at room temperature
- 1 1/2 cups granulated sugar
- 1/3 cup all-purpose flour
- 2/3 cup freshly squeezed lemon juice (from about 3 to 4 large, juicy lemons)
- 1 tablespoon lemon zest (for an extra punch of bright citrus flavor)
- Optional finish: Powdered sugar for dusting before slicing
Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper, leaving enough overhang on the sides to easily lift the baked bars out later. Lightly grease the parchment paper.
- Mix the Crust: In a medium bowl, cream together the softened unsalted butter and 1/2 cup of granulated sugar until smooth and creamy. Whisk in the 2 cups of flour and 1/4 teaspoon of salt until just combined and a crumbly dough forms.
- Bake the Crust: Press the dough evenly into the bottom of your prepared baking pan. Bake for 20 to 22 minutes, or until the edges are lightly golden brown.
- Whisk the Filling Ingredients: While the crust is baking, whisk together the 4 eggs, 1 1/2 cups of granulated sugar, 1/3 cup of flour, fresh lemon juice, and lemon zest in a mixing bowl until completely smooth and well incorporated.
- Pour and Bake the Filling: Once the crust is out of the oven, immediately pour the lemon filling mixture directly over the hot, pre-baked crust.
- Final Bake: Return the pan to the oven and bake for an additional 18 to 25 minutes, or until the center is set and no longer jiggles when gently shaken.
- Cool and Chill: Remove from the oven and allow the pan to cool completely at room temperature on a wire rack. Transfer the pan to the refrigerator for at least 2 hours to chill and firm up completely before slicing.
- Slice and Serve: Use the parchment paper overhang to lift the chilled slab out of the pan. Dust generously with powdered sugar just before slicing into clean, neat squares with a sharp knife.
Service Suggestions
- Dusting: A classic snow-like coating of sifted powdered sugar adds a touch of extra sweetness and visual elegance.
- Garnish: Serve alongside fresh raspberries, blackberries, or a small sprig of fresh mint to cut through the rich, tart curd.
- Dessert Plate: Pair a chilled lemon bar with a dollop of freshly whipped cream or a small scoop of vanilla bean ice cream for an elevated dessert experience.
Storage Tips
- Refrigeration: Because of the egg and citrus curd filling, leftover lemon bars must be stored in an airtight container in the refrigerator. They will keep fresh for up to 4 to 5 days.
- Freezing: You can freeze baked lemon bars (without the powdered sugar topping) for up to 3 months. Wrap individual bars tightly in plastic wrap and place them in a freezer-safe container. Thaw overnight in the refrigerator before serving, then dust with fresh powdered sugar.
FAQs
Can I use bottled lemon juice instead of fresh? While bottled lemon juice works in a pinch, it often contains preservatives and lacks the vibrant, aromatic oils found in fresh fruit. For the absolute best flavor and natural tartness, always use fresh-squeezed lemons.
Why did my lemon filling crack? Cracks in lemon bars usually happen if they are overbaked or if they cooled down too quickly. Make sure to pull them out as soon as the center is set, and let them cool gradually on the counter before chilling.
Can I double this recipe for a crowd? Yes! You can easily double the ingredients and bake them in a standard 9×13-inch pan. Keep an eye on the baking times, as a larger pan may require a few extra minutes in the oven.
