Ingredients

For the Shortbread Crust:

• 2 cups all-purpose flour
• 1/2 cup powdered sugar
• 1/2 teaspoon salt
• 1 cup unsalted butter, cold and cubed

For the Lemon Filling:

• 4 large eggs
• 1 1/3 cups granulated sugar
• 1/4 cup all-purpose flour
• 1/2 cup fresh lemon juice (about 3-4 lemons)
• 2 tablespoons lemon zest
• 1/4 teaspoon salt

For Finishing:

• 1/4 cup powdered sugar for dusting

Substitution Options:

• Gluten-free: Replace all-purpose flour with 1:1 gluten-free baking flour
• Dairy-free: Substitute cold vegan butter for regular butter
• Reduced sugar: Use 3/4 cup sugar in filling for more tart bars
• Lime variation: Replace lemon juice and zest with lime for a tropical twist

Time & Planning

Prep time: 15 minutes
Baking time: 45 minutes (20 minutes crust + 25 minutes with filling)
Total time: 1 hour plus 2 hours cooling time

Make-ahead tips:

• Prepare the crust up to 2 days ahead and store covered at room temperature
• Mix the lemon filling ingredients the morning of baking
• Finished bars keep covered for up to 4 days and actually taste better after day one

Time-saving advice:
While the crust pre-bakes, prepare your lemon filling so it’s ready to pour immediately when the crust comes out of the oven. This seamless transition helps prevent the crust from cooling too much.

How to Make It

1. Prepare Your Pan and Oven

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang for easy removal. Lightly grease the parchment with butter or cooking spray.

2. Make the Shortbread Crust

In a large bowl, whisk together flour, powdered sugar, and salt. Add the cold, cubed butter and use a pastry cutter or your fingers to work it in until the mixture resembles coarse crumbs with some pea-sized butter pieces. Press the mixture firmly and evenly into your prepared pan – the back of a measuring cup works perfectly for this.

3. Pre-bake the Crust

Bake for 18-20 minutes until the edges are lightly golden and the center looks set. You’ll know it’s ready when the surface no longer looks wet or raw.

4. Prepare the Lemon Filling

While the crust bakes, whisk the eggs in a large bowl until smooth. Add granulated sugar and whisk until well combined. Stir in flour, fresh lemon juice, lemon zest, and salt until the mixture is completely smooth with no lumps.

5. Assemble and Bake

Pour the lemon filling over the hot crust – this helps create a better seal between layers. Return to the oven and bake for 22-25 minutes until the filling is set and no longer jiggles when gently shaken.

6. Cool and Finish

Let the bars cool completely in the pan for at least 2 hours before cutting. Just before serving, dust generously with powdered sugar through a fine-mesh sieve.

Nutrition Overview

Each bar (when cut into 24 pieces) contains approximately:

• Calories: 165
• Carbohydrates: 28g
• Fat: 8g
• Protein: 3g
• Vitamin C: 8% daily value (from fresh lemon juice)

These bars provide a good source of citrus vitamin C and the satisfaction of a homemade treat. Nutritional values may vary based on specific ingredients used and portion sizes.

Healthier Variations

For lighter lemon bars, replace half the butter in the crust with Greek yogurt and reduce the sugar in the filling by 1/4 cup. The texture will be slightly more tender, but the flavor remains bright and satisfying.

You can also add a tablespoon of cornstarch to the filling for extra stability while using less sugar. For added nutrition, incorporate a tablespoon of chia seeds into the crust mixture for subtle crunch and omega-3 fatty acids.

Serving Ideas

These Lemon Bars shine on their own but pair beautifully with fresh berries or a dollop of lightly sweetened whipped cream. For an elegant presentation, serve your Lemon Bars alongside fresh mint sprigs and thin lemon slices.

They’re perfect for spring and summer gatherings, afternoon tea parties, or as a bright finish to heavy winter meals. Consider serving Lemon Bars with iced tea, sparkling water with lemon, or even a crisp white wine for adult gatherings.

Common Mistakes & How to Fix Them

Soggy bottom crust: Always pre-bake the crust until lightly golden and pour filling onto the hot crust for the best seal.

Filling won’t set: Ensure you’re measuring flour correctly and baking until the center no longer jiggles. Altitude can affect setting time, so add 3-5 extra minutes if needed.

Bars fall apart when cutting: Let them cool completely before cutting, and use a sharp knife wiped clean between cuts. The overnight rest really helps with clean slicing.

Too tart or too sweet: Taste your lemon juice before adding – some lemons are more acidic than others. Adjust sugar accordingly in 2-tablespoon increments.

Storage & Reheating

Store covered Lemon Bars in the refrigerator for up to 5 days. They’re delicious cold or at room temperature; let your Lemon Bars sit out for 15–20 minutes before serving if you prefer them less chilled.

For longer storage, freeze individual Lemon Bars wrapped in plastic wrap for up to 3 months. Thaw overnight in the refrigerator and dust your Lemon Bars with fresh powdered sugar before serving.

Avoid leaving Lemon Bars at room temperature for more than 2 hours due to the egg-based filling.

Helpful Tips for Success

Always use fresh lemon juice rather than bottled for the brightest flavor. Room temperature eggs mix more smoothly into the filling, so take them out 30 minutes before baking.

Press the crust firmly into the pan – loose crust will create a crumbly base that’s hard to cut cleanly. Don’t skip the parchment paper overhang; it makes removal effortless and prevents sticking.

For the cleanest cuts, chill the finished bars for 30 minutes before slicing, and dust with powdered sugar just before serving to prevent it from absorbing into the bars.

Conclusion

This reliable lemon bars recipe delivers bakery-quality results with simple techniques and everyday ingredients. The combination of buttery shortbread and bright lemon curd creates a dessert that’s both comforting and refreshing – perfect for any season or occasion.

The beauty of this recipe lies in its consistency and adaptability. Once you master the basic technique, you’ll find yourself reaching for this recipe again and again, whether you need a quick dessert for unexpected guests or want to contribute something special to a potluck.
