Why This Recipe Works
🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This isn’t just another lemon bar recipe; it’s the result of meticulous testing and tweaking to achieve the perfect balance. Here’s why it stands out:
- The Crust: We use a classic shortbread crust, which provides a sturdy, buttery base that complements the tangy lemon filling perfectly. The key is to pre-bake the crust until it’s lightly golden, preventing it from becoming soggy.
- The Lemon Filling: The ratio of lemon juice to sugar is carefully calibrated to achieve the ideal balance of tartness and sweetness. We also use a generous amount of lemon zest to amplify the bright citrus flavor. The eggs provide structure and richness, while a touch of flour helps to thicken the filling without making it gummy.
- The Baking Process: Baking the lemon bars at a relatively low temperature (325°F) ensures that the filling sets evenly without browning too quickly or cracking. This slow bake creates a smooth, creamy texture that melts in your mouth.
- The Cooling Process: Patience is key! Allowing the lemon bars to cool completely before cutting is crucial for a clean, professional look and prevents the filling from running.
Ingredients
Here’s what you’ll need to create these irresistible lemon bars:
For the Crust:
- 1 1/2 cups (180g) all-purpose flour
- 1/2 cup (1 stick, 113g) unsalted butter, cold and cubed
- 1/4 cup (50g) granulated sugar
- 1/4 teaspoon salt
For the Lemon Filling:
- 1 1/2 cups (300g) granulated sugar
- 1/4 cup (30g) all-purpose flour
- 1/4 teaspoon salt
- 4 large eggs
- 1/2 cup (120ml) fresh lemon juice (from about 3-4 lemons)
- 2 tablespoons lemon zest (from about 2 lemons)
- Powdered sugar, for dusting (optional)

Instructions
Follow these step-by-step instructions to create lemon bar perfection:
Step 1: Make the Crust
- Preheat oven to 350°F (175°C).
- In a medium bowl, whisk together the flour, sugar, and salt.
- Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
- Press the mixture firmly into the bottom of an ungreased 9×13 inch baking pan.
- Bake for 18-20 minutes, or until the crust is lightly golden brown.
Step 2: Prepare the Lemon Filling
- While the crust is baking, prepare the lemon filling. In a large bowl, whisk together the sugar, flour, and salt.
- Add the eggs and whisk until smooth.
- Stir in the lemon juice and lemon zest until well combined.
Step 3: Bake the Lemon Bars
- Pour the lemon filling over the pre-baked crust.
- Reduce oven temperature to 325°F (160°C).
- Bake for 25-30 minutes, or until the filling is set but still slightly jiggly in the center.
Step 4: Cool and Cut
- Let the lemon bars cool completely in the pan before cutting. This is crucial for a clean cut and prevents the filling from running. You can even refrigerate them for a couple of hours to speed up the process and ensure a firmer set.
- Once cooled, dust with powdered sugar (optional).
- Cut into squares or rectangles. A warm, clean knife dipped in hot water between cuts will help create neat slices.
Tips for Success
Here are a few extra tips to ensure your lemon bars are a resounding success:
- Use Fresh Lemon Juice: Bottled lemon juice simply doesn’t compare to the bright, vibrant flavor of freshly squeezed lemon juice. It’s worth the extra effort!
- Don’t Overbake: Overbaking will result in a dry, cracked filling. The filling should be set but still slightly jiggly in the center when you remove it from the oven.
- Chill Before Cutting: As mentioned earlier, chilling the lemon bars completely before cutting is essential for clean, professional-looking slices.
- Use a Light-Colored Pan: A light-colored baking pan will help prevent the crust from browning too quickly.
- Zest Carefully: When zesting the lemons, be careful not to zest the white pith, which is bitter.
- Experiment with Flavors: While this recipe is perfect as is, feel free to experiment with other citrus flavors. Try using a combination of lemon and lime juice, or add a touch of orange zest for a unique twist.
Storage Instructions
To keep your lemon bars fresh and delicious, store them in an airtight container in the refrigerator for up to 5 days. You can also freeze them for longer storage. To freeze, cut the lemon bars into individual squares, wrap them tightly in plastic wrap, and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. Thaw in the refrigerator before serving.

FAQ
💝 My Kitchen Favorites
The tools I use every day that make cooking a joy
Here are some frequently asked questions about making lemon bars:
- Can I use a different type of crust? While the shortbread crust is classic, you can experiment with other crusts, such as a graham cracker crust or a sugar cookie crust.
- Can I make this recipe gluten-free? Yes! Simply substitute the all-purpose flour with a gluten-free all-purpose flour blend.
- My lemon bars are too tart. What did I do wrong? The tartness of the lemon bars depends on the acidity of the lemons. If your lemons are particularly tart, you may want to add a little extra sugar to the filling.
- My lemon bars are too sweet. What did I do wrong? Make sure you’re measuring the sugar accurately. If you prefer a less sweet lemon bar, you can reduce the amount of sugar slightly.
- Why is my crust soggy? Soggy crust is usually caused by not pre-baking it long enough or by pouring the filling onto a hot crust. Make sure to pre-bake the crust until it’s lightly golden and allow it to cool slightly before adding the filling.
